�� Laing E-10 EcoCirc 6050U0013 Spa Circulation Pump – 115V 3/4″ MPT Threaded Threaded connections for leak-free installation with whisper-quiet ECM circulation technology �� Product Overview The Laing E-10 EcoCirc 6050U0013 is a 115V single-speed spa circulation pump with 3/4″ male pipe thread (MPT) connections and a 4-foot bare cord included, designed for continuous 24/7 low-flow heater circulation. This is the threaded-connection variant of the E-10 series — identical motor and performance to the barb versions, but with NPT threaded ports that provide a more secure, permanent connection for spas originally plumbed with threaded fittings. Powered by advanced Electronically Commutated Motor (ECM) technology, this pump consumes up to 40% less energy than the SM909 and SM1212 series it directly replaces. The magnetically driven open impeller eliminates the traditional shaft seal entirely — removing the number one failure point in conventional circulation pumps. Built with clog-resistant open impeller design using Polyphenylene Oxide (PPO) material, the E-10 handles debris that would stall closed-impeller pumps. The 32-bit motor with side vents provides improved cooling, while built-in dry run protection and soft start (~3 seconds) safeguard the pump and reduce mechanical stress. Delivering up to 15 GPM with a maximum head of 20 feet, this pump is OEM equipment in Marquis Spas (1994-1997 models including Euphoria, Reward, Mirage, Quest, Retreat, Oasis, Spirit, Voyage, Crossing, Secret, Departure, Destiny, and Serenity series) and is used across major spa brands. The threaded 3/4″ MPT connection is specifically required for spas with threaded plumbing — do NOT substitute a barb version for a threaded application without proper adapters. Compact, lightweight (under 5 lbs), and whisper-quiet, the E-10 fits tight equipment compartments with ease. ⭐ Key Features ✅ 3/4″ Male Pipe Thread (MPT) Connections — Threaded suction and discharge for secure, leak-free installation on spas with threaded plumbing ✅ ECM Technology — Electronically Commutated AC/DC/AC Spherical Motor consumes 40% less energy than previous SM909/SM1212 series ✅ 115V / 62W — Ultra-low power consumption for pennies-per-day continuous 24/7 operation ✅ 15 GPM Maximum Flow — Optimal flow for low-flow heater systems with 20 ft maximum head ✅ Magnetically Driven Open Impeller — NO shaft seal to leak or replace, plus clog-resistant PPO (Polyphenylene Oxide) construction ✅ Built-In Dry Run Protection — Embedded microprocessor automatically detects no-water condition and shuts down to prevent damage ✅ Soft Start Technology — Approximately 3-second gradual startup reduces mechanical stress and extends pump life ✅ 4-Foot Bare Cord INCLUDED — Pre-wired and ready for direct connection to spa control system ✅ 32-Bit Motor with Side Vents — Advanced motor design with improved heat dissipation for longer service life ✅ Marquis Spas OEM — Factory-installed in Marquis Spas 1994-1997 models (Euphoria, Reward, Quest, Mirage, and many more) ✅ 50/60 Hz Compatible — Works on both domestic (60 Hz) and international (50 Hz) electrical systems ✅ 1-Year Manufacturer Warranty — Full coverage from Laing Thermotech / Xylem ⚙️ Technical Specifications Specification Value Manufacturer Laing Thermotech (Xylem) Series E-10 EcoCirc Model E10-NSTN1W-19 / E10-NSTNDNN1W-02 Primary Part Number 6050U0013 Alternate Part Number 74009 UPC 733886740097 Pump Type Spa Circulation Pump — 24/7 Continuous Duty Motor Type Electronically Commutated AC/DC/AC Spherical Motor (ECM) Impeller Type Magnetically Driven, Open — Clog Resistant Impeller Material PPO (Polyphenylene Oxide) with High Density Ceramic Bearing Ball Shaft Seal NONE — Magnetically Driven (No Seal Required) Voltage 115V Frequency 50/60 Hz (Domestic and International) Phase Single Phase Wattage 62W at 115V / 60 Hz (3,100 RPM) RPM 3,100 Speed Single Speed Maximum Flow Rate 15 GPM Maximum Head 20 ft Maximum Working Pressure 50 PSI Maximum Temperature 140°F (60°C) Rotation Counter-Clockwise (Viewed from Motor End) Suction Connection 3/4″ Male Pipe Thread (MPT) — Center Suction Suction Physical Dimension 1″ OD Discharge Connection 3/4″ Male Pipe Thread (MPT) — Side Discharge Discharge Physical Dimension 1″ OD Volute Fastening 4 Bolts and 4 Nuts Wet End Material Thermoplastic Discharge Positions 4 Angles via Built-In Mounting Bracket Dimensions (L × H × W) 6″ × 4.88″ × 4.31″ Weight Under 5 lbs Noise Level Under 50 dB — Whisper Quiet Power Cord 4-Foot Bare Cord INCLUDED Mounting Bracket INCLUDED Drain Plug None Protection Features Dry Run Protection, Automatic Overload Protection, Soft Start (~3 sec) Warranty 1-Year Manufacturer Warranty ⚡ Electrical Requirements Electrical Spec Requirement Supply Voltage 115V (110V/120V same standard) Frequency 50/60 Hz Phase Single Phase Wattage 62W at 60 Hz RPM 3,100 at 60 Hz Power Cord 4-Foot Bare Cord INCLUDED Wiring 3 Wires: Hot, Neutral, Ground ⚠️ CRITICAL — 115V ONLY: This pump operates on 115V ONLY.

Ensure your female fittings accept standard 3/4″ NPT threads. General Installation Notes ⚠️ Pump must be installed below water level (flooded suction) to operate properly. ⚠️ Built-in dry run protection will shut down the pump if operated without water — however, always ensure flooded suction before starting. ⚠️ 4-foot bare cord has 3 wires with NO connectors on the cord end. Wire to your spa control system connecting hot, neutral, and ground per your spa’s wiring requirements. ⚠️ Soft start feature provides approximately 3-second gradual startup — this is normal operation, not a fault. ⚠️ Can be mounted horizontally or vertically with the motor end pointing down. Do NOT mount with motor end up. ⚠️ Counter-clockwise rotation when viewed from the motor end — do not attempt to reverse. ⚠️ GFCI protection is required by the National Electrical Code (NEC) for all hot tub and spa installations. ⚠️ 115V ONLY — verify your spa’s voltage before ordering. For 230V with threaded connections, order 6050U0014 or 73999. �� Maintenance Guide Routine Maintenance Task Frequency Notes Check threaded connections for leaks Monthly Re-seal with Teflon tape if needed Verify tight threaded fittings Monthly Do not over-tighten thermoplastic Check flow rate Monthly Reduced flow indicates blockage Inspect motor side vents Quarterly Keep clear of debris for cooling Verify quiet operation Quarterly Unusual noise indicates bearing wear Check mounting bracket Quarterly Tighten if loose Clean open impeller area As Needed Remove any debris if flow decreases Warning Signs — Replace Pump If: Unusual noise (grinding, humming, rattling) Motor overheating excessively Reduced or no water flow despite clear suction Motor trips breaker repeatedly Pump fails to start after soft start period Dry run protection activates repeatedly with water present Cracked wet end housing from over-tightened threaded connections Magnetically Driven Impeller — NO Seal Replacement Needed The Laing E-10 uses a magnetically driven impeller with NO mechanical shaft seal. Unlike conventional shaft-seal circulation pumps (Gecko CMHP, Waterway Iron Might, Balboa) where the seal is the most common failure point, the E-10’s magnetic drive completely eliminates this component. There is no seal to leak, wear out, or replace — ever. �� Ideal Applications Application Suitability Notes ♨️ 24/7 Spa Circulation ✅ Yes — Primary Use Continuous duty low-flow heater circulation ♨️ Low-Flow Heater Systems ✅ Yes — Primary Use 15 GPM max flow, 20 ft max head ♨️ Marquis Spas (1994-1997) ✅ Yes — OEM Replaces 630-6330 — direct factory replacement ♨️ Spas with Threaded Plumbing ✅ Yes — Primary Use 3/4″ NPT male thread connections ♨️ Replacement SM909-NT (Threaded) ✅ Yes — Direct Replaces ALL SM909 and SM1212 threaded models ♨️ Sundance / L.A. / Atlantic Coast ✅ Yes Threaded connection models ♨️ Gatsby / Hawkeye / Royal / Saratoga ✅ Yes Threaded connection models ♨️ Ozone Treatment Systems ✅ Yes Compatible with ozone injection ♨️ Saltwater Spa Systems ✅ Yes Saltwater compatible �� Spas with 3/4″ Barb Plumbing ❌ No — Wrong Type Use 6050U0015 (3/4″ barb, 115V) instead �� Spas with 1″ Barb Plumbing ❌ No — Wrong Size Use 6050U0011 (1″ barb, 115V) instead �� 230V Spa ❌ No — 115V Only Use 6050U0014 or 73999 (3/4″ MPT, 230V) �� 1-1/2″ MBT Plumbing ❌ No Use Gecko Aqua-Flo CMHP for 1-1/2″ connections ❓ Frequently Asked Questions Q: What does MPT mean? A: MPT stands for Male Pipe Thread — also called NPT (National Pipe Thread). The pump has external threads that screw into a female threaded fitting on your spa’s plumbing. This is different from barb connections, which slide into flexible hose and are secured with hose clamps. Q: What is the flow rate of this pump? A: Maximum 15 GPM with a maximum head of 20 feet. Designed for continuous 24/7 low-flow heater spa circulation. Q: What is the physical outside diameter of the threaded connections? A: The 3/4″ MPT threads have a physical outside diameter of 1″ OD. This is standard for 3/4″ NPT pipe threads. Your female fittings must accept standard 3/4″ NPT threads. Q: Does this pump come with a power cord? A: Yes. A 4-foot bare cord with 3 wires is included and pre-wired to the pump. The cord end has NO connectors — you wire directly to your spa’s control system connecting hot, neutral, and ground. Q: Can I use this pump if my spa has barb connections? A: No. Threaded (MPT) and barb connections are not interchangeable. If your spa uses hose barb connections, order the 6050U0015 (3/4″ barb) or 6050U0011 (1″ barb) instead. Using the wrong connection type will result in leaks or inability to install. Q: Does this fit Marquis Spas? A: Yes. The 6050U0013 (Marquis part 630-6330) is the OEM factory circulation pump for Marquis Spas from 1994-1997, including Euphoria, Reward, Quest, Mirage, Retreat, Oasis, Spirit, Voyage, Crossing, Secret, Departure, Destiny, and Serenity models. Q: Does this replace the Laing SM909-NT threaded series? A: Yes. The E-10 directly replaces ALL SM909 and SM1212 threaded (NT) series models while consuming up to 40% less energy: 909-NT-14 (6845, 6 GPM), 909-NT-26 (6850, 9.5 GPM), and 909-NT-18 (6831, 11 GPM). Q: Does this pump have a shaft seal? A: No. The E-10 uses a magnetically driven impeller that completely eliminates the mechanical shaft seal. There is no seal to leak, wear out, or replace. Q: What is dry run protection? A: The E-10 has an embedded microprocessor that automatically detects when the pump is running without water and shuts it down to prevent motor and pump damage. Q: Should I use Teflon tape on the threads? A: Yes. Apply Teflon tape or pipe thread sealant to the male threads before screwing into female fittings. Hand-tighten first, then wrench-tighten 1-2 additional turns. Do NOT over-tighten as the thermoplastic wet end can crack. Q: Can I mount this pump vertically? A: Yes. The E-10 can be mounted horizontally or vertically with the motor end pointing down. Do NOT mount with motor end up. Q: What voltage does this pump require? A: 115V ONLY (also referenced as 110V or 120V — same standard). Works on both 50 Hz and 60 Hz. For 230V with threaded connections, order 6050U0014 or 73999. Q: Is this pump quiet? A: Yes, extremely. The E-10 operates whisper-quiet at under 50 dB. The ECM motor with soft start technology contributes to virtually silent operation. Q: Do I need a GFCI breaker? A: Yes. GFCI protection is required by the National Electrical Code (NEC) for all hot tub and spa installations. Q: What warranty is included? A: 1-year manufacturer warranty from Laing Thermotech / Xylem.

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. If you're unsure or uncomfortable with any aspect of this process, please do get in touch, happy to help. How do I know what size hot tub pump I have? 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. If you're unsure about any aspect of this process, get in touch, always happy to help.
