⚙️ Gecko Aqua-Flo Circ-Master CMHP Spa Circulation Pump — 1/15 HP Single Speed 230V Side Discharge (02093001-2010) Energy-efficient 230V side-discharge circulation for professional spa filtration systems �� Product Overview The Gecko Aqua-Flo Circ-Master CMHP (model 02093001-2010) is the 230-volt version of Gecko Alliance’s premium single-speed circulation pump, engineered for continuous 24-hour hot tub and spa filtration. Running at just 0.6 amps, this 1/15 HP pump delivers up to 40 GPM — the highest flow rate of any recirculation pump in the spa industry — while drawing half the current of its 115V counterpart. The CMHP features a side discharge wet end configuration with the discharge port at the 12 o’clock position and a centered suction port, both equipped with 1-1/2″ male buttress thread (MBT) connections. Its compact NEMA 48-frame thru-bolt motor with permanently lubricated sealed ball bearings provides quiet, maintenance-free operation over thousands of hours. The 230V design is standard in most permanently wired spa installations where a dedicated 230V circuit is already in place for the heater and jet pumps, making it the most common version for full-size hot tubs. This pump is widely used across many spa brands including Sundance, Beachcomber, Coleman/Maax, Baja, Pacific, and others. It is UL Listed (E62386) and California Title 20 Compliant. ⚠️ CRITICAL VOLTAGE WARNING: This is the 230V model. If your spa provides 115V to the circulation pump, you need model 02093000-2010 instead. Verify your existing pump’s voltage label or your spa’s wiring diagram before ordering. Connecting this pump to 115V will result in insufficient performance. Connecting a 115V pump to 230V will destroy the motor. ⚠️ SIDE DISCHARGE vs. CENTER DISCHARGE: This is the CMHP (side discharge) model. If your existing pump has both suction and discharge ports centered, you need the CMCP model (02593001-2010) instead. Verify your existing pump’s discharge position before ordering. ✨ Key Features ✅ 24-Hour Continuous Duty Motor — NEMA 48-frame thru-bolt motor with permanently lubricated sealed ball bearings rated for uninterrupted 24/7 operation, maximizing filtration and heat distribution ✅ Industry-Leading Flow Rate — Up to 40 GPM — Delivers the highest GPM of any recirculation pump in the spa industry, enabling efficient heating and superior water clarity ✅ Ultra-Low 0.6A Draw at 230V — Half the amperage of the 115V version while delivering identical performance, reducing electrical load on your spa’s main circuit ✅ Side Discharge Wet End (CMHP) — Discharge port at 12 o’clock position with centered suction, ideal for spa equipment bays with top-exit or side-exit plumbing configurations ✅ 1-1/2″ MBT Connections — Standard 1-1/2″ male buttress thread on both suction and discharge ports (approximately 2-3/8″ outside thread diameter) with included union fittings ✅ Carbon-Graphite Self-Lubricating Seal — Viton-compatible seal designed specifically for continuous duty operation, providing superior leak protection ✅ Rotatable Wet End — 4 Positions — Wet end can be oriented in 90-degree increments to align with existing plumbing without modifying pipe runs ✅ Quick-Release Compression Fittings — Included union fittings (2x white 2″ union nuts with 1-1/2″ slip tail pieces and O-rings) allow easy installation and maintenance ✅ Three Wing Nut Drain Plugs — Positioned at 3, 6, and 9 o’clock for complete drainage regardless of pump orientation ✅ UL Listed (E62386) & California Title 20 Compliant — Independently tested and approved for safety compliance and energy efficiency standards �� Technical Specifications Specification Value Pump Type Circulation Pump (24-Hour Continuous Duty) Model Number 02093001-2010 Manufacturer Gecko Alliance (Aqua-Flo Brand) Series Circ-Master CMHP Motor Power 1/15 HP (Operating) Speed Settings Single Speed RPM 1,725 (60 Hz) / 1,425 (50 Hz) Motor Type PSC (Permanent Split Capacitor) Flow Rate (Max) 40 GPM Maximum Head 3.8 PSI / 8.9 ft (2.7 m) Voltage 230V (also listed as 220V/240V — all refer to the same pump) Frequency 60 Hz (also compatible with 50 Hz at reduced RPM) Amperage 0.6A Frame Type NEMA 48 Thru-Bolt (48Y) Discharge Port Size 1-1/2″ MBT Suction Port Size 1-1/2″ MBT Discharge Position Side (12 o’clock standard) Suction Position Center Connection Physical OD Approximately 2-3/8″ (thread to thread) Dimensions (Approx.) 12.5″ L × 6.83″ W × 8.25″ H Weight 15 lbs (approx.)

Hot tubs and spas require GFCI (Ground Fault Circuit Interrupter) protection on the supply circuit. This is a code requirement — not optional. The motor must be bonded with no smaller than #8 AWG solid copper conductor per the National Electrical Code. The bonding connection should be made from the accessible wire connector on the motor to all metal parts of the spa structure and to all electrical equipment, metal conduit, and metal piping within 5 feet of the inside walls of the spa. A dedicated circuit is required — do not share with other appliances. ⚠️ Cord Not Included: This pump ships without a power cord. Most 230V spa installations are hardwired directly to the spa control system. If your system uses an AMP plug connection, a compatible pump cord is available separately from Parts4Tubs. �� Compatibility Guide Frame & Mounting: Detail Specification Frame Type NEMA 48 Thru-Bolt (48Y) Wet End Style CMHP (Side Discharge) Suction Port 1-1/2″ MBT — Center Discharge Port 1-1/2″ MBT — Side (12 o’clock standard) Connection OD Approximately 2-3/8″ (thread to thread) Unions Included 2x White 2″ Union Nuts with 1-1/2″ Slip Tail Pieces and O-Rings ⚠️ CMHP vs. CMCP — Critical Difference: The CMHP (this model) has a side discharge wet end with the discharge port positioned at the 12 o’clock position and the suction port centered. The CMCP (model 02593001-2010 for 230V) has a center discharge wet end with both suction and discharge ports centered. Both share the same frame and motor type, but the wet end orientation differs significantly. Installing the wrong model will require plumbing modifications. Verify your existing pump’s discharge position before ordering. 115V vs. 230V — Which Do I Need? This is the 230V model (02093001-2010). The 115V version is model 02093000-2010. Most permanently installed full-size hot tubs use 230V for the circulation pump, as they already have a 230V supply for the heater and jet pumps. Portable plug-and-play spas typically use 115V. Check the voltage label on your existing pump or consult your spa’s wiring diagram. Measuring Your Existing Pump Connections: To confirm 1-1/2″ connections, measure the outside diameter of the inlet and outlet fittings on your existing pump. A measurement of approximately 2-3/8″ indicates a 1-1/2″ connection. A measurement of approximately 3″ indicates a 2″ connection. A measurement of approximately 3-5/8″ indicates a 2-1/2″ connection. Verified Replacement Compatibility: This pump is confirmed as a direct replacement across multiple authorized retailers for the following spa brand pumps: Brand / Application Part Number(s) Sundance Spas 6500-907, 6000-907 Beachcomber (Hush Pump) 02093007-2, 02093695-2 Coleman / Maax Spas 104440, 108897 Baja Spas 02410002-2 (101086-009) Pacific Spas 02093646-2 Theramax II 024110512-2 Waterway Iron Might (230V) 3410020-1E (alternative replacement) �� Wet End Component Part Numbers Component Part Number Impeller 91693601 Wet End Assembly (CMHP) 91040700-000 Motor (230V) K55MYGRD-8367 Seal BSP-200 (Viton compatible) Shaft Seal Kit Compatible with Aqua-Flo Viton 200 seal kit ⚠️ Note: The CMHP wet end assembly (91040700-000) is the same for both 115V and 230V versions. The motor is different: the 230V uses motor K55MYGRD-8367, while the 115V uses K55MYGJN-8255. The impeller (91693601) and seal are shared across both voltage versions. ⚠️ CE Motor Variant: A CE motor version exists (02093001-2010CE) with slightly different motor dimensions: 9-11/16″ × 8-3/16″ × 8-1/4″ versus 9-1/8″ × 6-7/16″ × 8-5/16″ for the standard motor. The CE variant is functionally identical but physically wider. Verify clearance in your equipment bay if considering the CE motor version. ��️ Installation Requirements Mounting & Placement: Requirement Specification Mounting Position Horizontal (below water level — flooded suction required) Base Solid, level surface with vibration-dampening pad Ventilation Ensure all motor louver openings remain free from debris and obstructions Access Provide adequate clearance around pump and above discharge port for inspections and maintenance Plumbing: Connection Size Suction 1-1/2″ MBT (Center) Discharge 1-1/2″ MBT (Side — 12 o’clock standard) Union Type Quick-release compression fittings (included) Installation Notes: ⚠️ This pump must be installed below water level (flooded suction). Ensure the pump casing (volute) will be completely filled with water during operation. ⚠️ Never run the pump dry. Always verify the pump casing is filled with water before starting. Allow reasonable time for priming. ⚠️ For Aqua-Flo compression fittings, DO NOT use thread seal tape (PTFE tape), Teflon, Quick-Seal Thread Sealing Compound, Plasto-Joint Stik, or any other sealants. These fittings are designed to seal with the included O-rings only. Hand tighten only — do not use a wrench. ⚠️ The wet end can be rotated in 90-degree increments to align with your existing plumbing. Loosen the 8 volute screws, rotate to the desired position, and retighten. The standard wet end position has the discharge at 12 o’clock. ⚠️ Ensure proper grounding and bonding per NEC requirements using #8 AWG solid copper conductor. ⚠️ GFCI protection is required by the National Electrical Code for all hot tub and spa installations. ⚠️ Verify your spa control system provides a 230V output for the circulation pump before connecting. Wiring a 230V pump to 115V will result in the pump running at reduced speed with insufficient flow. Wiring a 115V pump to 230V will immediately destroy the motor. ⚙️ Maintenance Guide Routine Maintenance: Task Frequency Notes Check for leaks around seal and unions Monthly Look for drips or moisture at connections — pay attention to the side discharge union Inspect union fittings Monthly Hand tighten if loose — do not over-tighten Verify motor vents are clear Quarterly Remove debris, leaves, or obstructions from motor openings Check mounting bolts and base Quarterly Tighten if vibration has loosened Inspect amperage draw Annually Should read approximately 0.6A at 230V Clean strainer/filter basket As needed Remove debris to maintain flow Warning Signs — Replace or Service Pump If: Unusual noise such as grinding, screeching, or rattling may indicate bearing failure or impeller damage. Water leaking from the seal area means the carbon-graphite seal has worn and requires replacement. If the motor repeatedly trips the breaker, there may be an electrical fault or the GFCI is detecting a ground current — discontinue use immediately and have the pump inspected. Reduced water flow could indicate a clogged impeller, worn seal, or failing motor. Motor overheating or a burning smell indicates the motor windings may be damaged. Seal Replacement: The Circ-Master CMHP uses a carbon-graphite self-lubricating seal (BSP-200) compatible with the Aqua-Flo Viton 200 shaft seal kit. Replace the seal at the first sign of leakage. Both halves of the seal (carbon and ceramic) should be replaced together every time the pump is disassembled. Ensure seal surfaces are smooth, clean, and free from damage before reassembly. Winterization: To prevent freeze damage, disconnect all electrical power, drain the pump thoroughly using the wing nut drain plugs at 3, 6, and 9 o’clock positions, and remove any remaining water. Protect the pump and motor from the elements by covering or storing in a dry, well-ventilated area. �� Ideal Applications Application Suitability Notes ♨️ Hot tub 24-hour circulation (230V systems) Yes Primary application — the most common voltage for permanently installed hot tubs ♨️ Spa heating loop Yes High GPM enables efficient heat distribution through flow-through heaters ♨️ Ozone/sanitizer distribution Yes Continuous circulation ensures even distribution of sanitizer throughout spa water ♨️ Equipment bays with top-exit plumbing Yes Side discharge (12 o’clock) configuration ideal for upward plumbing runs ♨️ Replacement for Sundance, Beachcomber, Coleman spas Yes Verified drop-in replacement for multiple major spa brands �� Whirlpool bath circulation See note Designed for spa systems — verify plumbing, electrical compatibility, and voltage for whirlpool applications �� 230V vs. 115V Comparison Specification 230V (This Model) 115V (02093000-2010) Model Number 02093001-2010 02093000-2010 Voltage 230V 115V Amperage 0.6A 1.3A Motor Part Number K55MYGRD-8367 K55MYGJN-8255 Flow Rate 40 GPM 40 GPM Max Head 3.8 PSI / 8.9 ft 3.8 PSI / 8.9 ft HP 1/15 HP 1/15 HP Frame 48Y 48Y Connections 1-1/2″ MBT 1-1/2″ MBT Wet End CMHP (Side Discharge) CMHP (Side Discharge) Dimensions 12.5″ × 6.83″ × 8.25″ 12.5″ × 6.5″ × 8.25″ Wattage ~138W (230V × 0.6A) ~150W (115V × 1.3A) Both versions deliver identical hydraulic performance.

A: This pump is rated at 1/15 HP (0.067 HP operating) and draws approximately 0.6 amps at 230V/60Hz. Gecko also lists 0.13 HP output power, reflecting a different rating method. It is designed for continuous-duty 24-hour circulation, not for powering jets. Q: Will this pump fit my hot tub? A: This pump uses a NEMA 48 thru-bolt frame with 1-1/2″ male buttress thread connections. The suction is centered and the discharge is at the side (12 o’clock position). The connections measure approximately 2-3/8″ from thread to thread. Match your existing pump’s frame size, port sizes, discharge position, and voltage to confirm compatibility. Q: What is the difference between the CMHP and the CMCP? A: The CMHP (this model) has a side discharge wet end with the discharge positioned at 12 o’clock. The CMCP (model 02593001-2010 for 230V) has a center discharge wet end with both suction and discharge centered. Both use the same frame and motor type, but the wet end orientation differs. Check your existing pump’s discharge location before ordering. Q: My spa uses 230V for the jet pumps and heater. Will this pump work? A: Most likely yes, but you must verify that your spa control system provides a dedicated 230V output for the circulation pump specifically. Some spa packs provide 115V for the circulation pump even when the main supply is 230V. Check the label on your existing circulation pump or consult your spa’s wiring diagram. Q: Does this pump come with a power cord? A: No. This pump ships without a cord and requires hardwire installation or a compatible AMP plug cord purchased separately. Most 230V spa installations are hardwired directly to the control system. Q: Does this pump come with union fittings? A: Yes. The pump includes 2x white 2″ union nuts with 1-1/2″ slip tail pieces and O-rings for easy installation. Q: Can I use thread tape on the fittings? A: No. Aqua-Flo’s compression fittings are designed to seal with the included O-rings only. Do NOT use any thread seal tape, Teflon, or sealant compounds. Hand tighten only. Q: Can this replace a Sundance 6500-907 or 6000-907? A: Yes. Multiple authorized retailers confirm the CMHP 02093001-2010 is a direct replacement for both Sundance part numbers 6500-907 and 6000-907. Q: Can this replace a Beachcomber Hush Pump? A: Yes. This pump directly replaces Beachcomber Hush Pump models 02093007-2 and 02093695-2. Q: Is this the same as model 02093001-2? A: Yes.

Keep in mind that the specific steps may vary depending on your hot tub's make and model, so it's essential to consult your hot tub's manual for model-specific instructions. If you're not comfortable with this procedure, it's a good idea to seek professional assistance. Materials You'll Need: Replacement pump Pipe wrench Adjustable wrench Screwdriver Pipe sealant (thread tape or plumber's putty) PVC primer and cement (if you have PVC plumbing) Teflon tape (for threaded connections) Procedure: Turn Off the Power: Before you begin, ensure the hot tub's power supply is turned off at the circuit breaker or disconnect switch. Safety should always be a priority when working with electrical components. Drain the Hot Tub: If your hot tub is not already empty, you'll need to drain it. Follow your hot tub's manual or manufacturer's instructions for proper draining. (You might not need to do this if you can lock the pump off with the gate valves) Locate the Pump: Identify the location of the existing pump in your hot tub. It's usually located near the equipment area or in a designated pump compartment. Disconnect the Electrical Wiring: Carefully disconnect the electrical wiring from the old pump. This typically involves removing the electrical conduit cover, unscrewing wire nuts, and disconnecting the wires from the terminals. Be sure to note the wire connections or take a picture for reference when connecting the new pump. Disconnect the Plumbing: Depending on your hot tub's plumbing setup, you'll need to disconnect the plumbing connections to the pump. Use a pipe wrench or adjustable wrench to loosen and remove the fittings. Be prepared for some water spillage when disconnecting the plumbing. Remove the Old Pump: Once the electrical and plumbing connections are detached, carefully remove the old pump from its mounting position. Some pumps may be secured with mounting brackets or bolts. Prepare the New Pump: If the new pump is not pre-assembled, you may need to attach fittings, unions, or adapters to match your hot tub's plumbing. Ensure that you use the appropriate sealant or Teflon tape on threaded connections to prevent leaks. Mount the New Pump: Position the new pump in the same location as the old one and secure it in place using the mounting brackets or bolts. Reconnect Plumbing: Reconnect the plumbing to the new pump, ensuring that all connections are tight and secure. If your hot tub uses PVC plumbing, use PVC primer and cement to bond the connections properly. Reconnect Electrical Wiring: Reconnect the electrical wiring to the new pump, following the notes or pictures you took earlier. Make sure all wires are properly connected and secure. Turn On the Power: Restore power to the hot tub by switching on the circuit breaker or reconnecting the disconnect switch. Test the Pump: Turn on the hot tub's pump to ensure that it's working correctly. Check for any signs of leaks or irregularities in the plumbing connections. Refill the Hot Tub: Once you've confirmed that the new pump is functioning properly, refill the hot tub with water. Check for Leaks: Inspect the plumbing connections for any leaks. If you find any, turn off the pump, drain the tub again, and reseal the connections as needed. Monitor: Keep an eye on the pump and plumbing for the next few days to ensure everything is functioning correctly and that there are no further issues. Remember that this is a general guideline, and the specific steps may vary based on your hot tub's design.

Determining the size of your hot tub pump is an important step when it comes to maintenance or replacement. To find out the size of your hot tub pump, follow these steps: Check the Manual: The easiest way to determine the size of your hot tub pump is to consult the owner's manual or user documentation that came with your hot tub. The manual typically contains detailed information about the specifications and components of your hot tub, including the pump. Look at the Pump Housing: If you don't have access to the manual or it doesn't provide the information you need, inspect the pump itself. Most hot tub pumps have a label or plate on the pump housing that displays essential details, including the pump's model number, manufacturer, and specifications. You can then send that to me or Google it. Measure the Pump: If the label is missing or damaged, you can measure the pump's dimensions. Measure the diameter of the pump's wet end (the part where the water flows) and the length of the wet end. These measurements can help identify the size and capacity of the pump. Consult the Manufacturer: If you can't find the information on the pump or in the manual, contact the hot tub manufacturer or a reputable dealer. Provide them with your hot tub's model and serial number, and they should be able to identify the correct pump size for your specific hot tub. Online Research: You can also search online using the pump's model number or hot tub's make and model. Many manufacturers provide detailed information about their products on their websites, and you may find specifications for your pump model. Once you have determined the size and specifications of your hot tub pump, you can proceed with maintenance, repairs, or replacement if necessary. Keep in mind that replacing a hot tub pump with the same size and capacity as the original is crucial to ensure proper water circulation and filtration in your hot tub.
