��️ Balboa Dura-Jet DJAYFA Spa Pump 4239113-S — 1.5 HP 2-Speed 115V 48 Frame Compact, whisper-quiet jet performance with multi-directional volute for effortless spa installation �� Product Overview The Balboa Dura-Jet DJAYFA (Part No. 4239113-S) is a 1.5 HP, dual-speed, 115V jet pump from the award-winning Dura-Jet (Cascade) series by Balboa Water Group / Sta-Rite. Engineered for exceptional performance in a compact 48-frame package, this pump delivers powerful hydrotherapy jet action on high speed (3,450 RPM) and energy-efficient filtration and heating on low speed (1,725 RPM) — giving you the best of both worlds from a single pump. What sets the Dura-Jet apart from competitors is its unique impeller design, which delivers higher efficiency flow with a smaller horsepower motor than other pumps in the same class — the Dura-Jet series is rated for flow rates exceeding 210 GPM. The petite volute and compact 48-frame design allow easy installation in tight equipment bays where larger 56-frame pumps simply won’t fit. The multi-directional volute can be rotated to four positions (12, 3, 6, and 9 o’clock) and includes a 3-position drain plug for complete configuration flexibility. All Dura-Jet seals are carbon ceramic with Viton® elastomers, providing long-lasting performance that easily endures prolonged heat and chemical exposure in spa environments. With Class F insulation and whisper-quiet operation, the DJAYFA is used as OEM equipment by Dimension One Spas, Hawkeye Spas, Master Spas, Great Lakes Spas, and many other major spa manufacturers. The Dura-Jet line has earned an industry reputation for being durable, reliable, quiet, trouble-free, and efficient. ⭐ Key Features ✅ 1.5 HP True Rated / 2-Speed — High speed (3,450 RPM) for powerful jets, low speed (1,725 RPM) for energy-efficient filtration and heating ✅ 115V / 60Hz — Standard US 115V spa circuit compatible — ideal for plug-and-play or convertible spas ✅ Compact 48-Frame Design — Petite volute fits in tight equipment bays where 56-frame pumps won’t ✅ High-Efficiency Impeller — Unique design delivers higher flow with smaller HP than competing pumps — series exceeds 210 GPM ✅ Multi-Directional Volute — Rotates to 4 positions (12, 3, 6, 9 o’clock) for flexible plumbing orientation ✅ 3-Position Drain Plug — Complete flexibility of configuration for any installation ✅ Carbon Ceramic Seal with Viton® Elastomers — Engineered for prolonged heat and chemical exposure ✅ Class F Insulation — Rated for high-temperature motor environments (up to 155°C / 311°F) ✅ Whisper-Quiet Operation — Near-silent performance for a peaceful spa experience ✅ 2″ MBT In/Out — Center suction and radial side discharge with ~3.1″ (3-1/16″) thread outer diameter ✅ OEM Proven — Used by Dimension One, Hawkeye, Master Spas, Great Lakes Spas, and more ✅ Manufacturer Warranty — Backed by Balboa Water Group ⚙️ Technical Specifications Specification Value Part Number 4239113-S Alternate Part Numbers 4239113-S/B, 4239113-B, DJAYFA-0101, DJAYFA-0003, DJAYFA-0001, 15-175-2196, VIC4239113S, 239113-S Manufacturer Balboa Water Group / Sta-Rite (Dura-Jet / Cascade series) Model Designation DJAYFA Pump Type Jet Pump (2-Speed) Series Dura-Jet (DJ) / Cascade Motor Power 1.5 HP (true rated) Speed Settings 2-Speed High Speed RPM 3,450 Low Speed RPM 1,725 Voltage 115V Frequency 60 Hz Phase Single High Speed Amperage 13.0A Low Speed Amperage 3.7A Frame Type 48 (48Y) Insulation Class F Suction Port Size 2″ MBT (Male Buttress Thread) Discharge Port Size 2″ MBT (Male Buttress Thread) Thread Outer Diameter Approximately 3.1″ (3-1/16″) Suction Location Center (front face) Discharge Location Radial side — rotatable to 4 positions Seal Type Carbon ceramic with Viton® elastomers Volute Multi-directional mounting — 3-position drain plug Dimensions (L × W × H) Please refer to manufacturer documentation or contact Parts4Tubs for details Weight Please refer to manufacturer documentation or contact Parts4Tubs for details Cord Included No — use existing cord or purchase separately Unions Included No — sold separately (O-rings included with unions) Warranty Manufacturer warranty — contact Parts4Tubs for full terms ⚠️ Amperage Note: Most sources consistently list 13.0/3.7A (high/low) for this pump. Some distributors list 13.8/3.8A, which may reflect a slightly different motor revision. Pump and motor manufacturers reserve the right to change motors without notice while maintaining the same functionality. Always verify the motor nameplate rating on your specific pump. �� Electrical Requirements Electrical Spec Requirement Supply Voltage 115V Frequency 60 Hz Phase Single Full Load Amps (High Speed) 13.0A Full Load Amps (Low Speed) 3.7A Minimum Circuit Breaker 20A (per HotTubOutpost recommendation for 13A high-speed draw on 115V) Insulation Class F ⚠️ IMPORTANT: All electrical work must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local and state building codes. Hot tubs and spas require GFCI (Ground Fault Circuit Interrupter) protection. A dedicated circuit is required — do not share with other appliances. This is a 115V pump. Do NOT connect to a 230V circuit. If your spa requires a 230V pump, order the appropriate 230V Dura-Jet model instead. Using the wrong voltage will damage the motor and void the warranty. This pump does NOT include a power cord. You will need to use your existing pump AMP cord or purchase a new one. Refer to Balboa/Sta-Rite wiring instructions for proper cord installation. �� Compatibility Guide This Pump: �� Frame: 48 (48Y) �� Suction: 2″ MBT — Center (front face) �� Discharge: 2″ MBT — Radial side (rotatable to 4 positions) �� Thread OD: ~3.1″ (3-1/16″) Discharge Rotation Positions (as you face the wet end): Position Clock Reference Up (standard shipping position) 12 o’clock Right 3 o’clock Down (rare) 6 o’clock Left 9 o’clock Rotation is done by loosening the four long bolts at the back of the motor.

A: The true rated (continuous) horsepower is 1.5 HP, as confirmed by the manufacturer’s Dura-Jet owner’s manual (S377) and all major authorized distributors. Parts4Tubs lists “2 HP” in the product title, which likely refers to a brake horsepower or service factor rating. The DJAYFA model designation in the Sta-Rite manual is categorized under 1-1/2 HP. When comparing pumps, always match the true rated HP and amperage draw (13.0/3.7A for this model). Q: Will this pump fit my hot tub? A: This pump has a 48-frame motor with 2″ MBT center suction and 2″ MBT radial side discharge. The thread outer diameter measures approximately 3.1″ (3-1/16″). Match these specifications to your existing pump. The Dura-Jet’s compact petite volute design fits many equipment bays where larger 56-frame pumps cannot. Q: What voltage does this pump require? A: 115V / 60Hz. All electrical installation must be performed by a licensed electrician. Do NOT connect to a 230V circuit. Q: Does a cord come with this pump? A: No. Most Dura-Jet pumps ship without a power cord. You will need to use your existing pump AMP cord or purchase a new one separately. Q: Do unions come with this pump? A: No. Pump unions are sold separately. If retrofitting, you’ll need a pair of 2″ pump unions (with approximately 3.1″ OD threads) that connect to your existing pipes. O-rings are included with the pump unions. Q: Can I rotate the discharge direction? A: Yes. The discharge can be rotated to 4 positions (12, 3, 6, and 9 o’clock) by loosening the four long bolts at the back of the motor. The pump ships from the factory with discharge pointing up (12 o’clock). We recommend having rotation performed by a qualified spa technician to avoid leaks that may affect the warranty. Q: What size are the ports? A: Both suction (center) and discharge (side) are 2″ MBT (Male Buttress Thread). The outer thread diameter is approximately 3.1″ (3-1/16″). Q: What spa brands use this pump? A: The DJAYFA Dura-Jet is used as OEM equipment in Dimension One Spas, Hawkeye Spas, Master Spas, Great Lakes Spas, and many other brands. Q: What is the amperage draw? A: 13.0A on high speed and 3.7A on low speed at 115V/60Hz. Some distributors list 13.8/3.8A which may reflect a different motor revision. Always verify the nameplate rating on your specific pump. Q: What warranty is included? A: This pump is backed by a manufacturer warranty from Balboa Water Group. Contact Parts4Tubs for full warranty terms and coverage details. 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 electrical installations. Q: What is the difference between DJAYFA and DJAYEA? A: DJAYFA designates 1.5 HP Dura-Jet models, while DJAYEA designates 1.0 HP models. Both use the same compact 48-frame design, 2″ ports, and Dura-Jet wet end — but DJAYFA delivers more power (13.0/3.7A vs 10.4/3.6A) for stronger jet performance. Q: Can I use this as a single-speed pump? A: Yes. When using as a single-speed pump, the low-speed terminal is simply not connected. The pump will only operate on high speed. �� Downloads & Resources �� Sta-Rite Dura-Jet Spa Pump Owner’s Manual (S377) — Complete installation, operation, electrical wiring, troubleshooting, and repair parts list covering all DJ series models, including DJAYFA �� Why Choose the Balboa Dura-Jet DJAYFA ✅ High-efficiency impeller — Delivers more flow per HP than competitors — series exceeds 210 GPM ✅ Compact 48-frame design — Fits tight equipment bays where 56-frame pumps won’t ✅ Carbon ceramic / Viton® seal — Engineered for long service life in harsh spa chemical environments ✅ Multi-directional volute — 4-position discharge rotation plus 3-position drain plug for total installation flexibility ✅ Whisper-quiet operation — Near-silent performance for a peaceful spa experience ✅ Dual-speed efficiency — Full jet power on high, energy-saving filtration on low ✅ Class F insulation — Premium motor protection for demanding spa environments ✅ OEM-proven reliability — Used by Dimension One, Master Spas, Great Lakes, and more ✅ Massive cross-reference compatibility — Replaces 25 DJAYFA part number variants �� Why Buy from Parts4Tubs ✅ US-based support for American customers ✅ Fast shipping across the United States ✅ Expert advice from spa and hot tub specialists ✅ Competitive pricing in USD ✅ Full warranty support ✅ Hassle-free returns ✅ Replacement seals, cords, and unions available ✅ Dedicated customer service team ✨ Summary The Balboa Dura-Jet DJAYFA (4239113-S) is a 1.5 HP true rated, 2-speed, 115V jet pump in the award-winning Dura-Jet (Cascade) series.

O-ring gaskets may vary between manufacturers - measure your existing gasket for accuracy. How do I Replace a Hot Tub Pump? Here's a general step-by-step guide on how to replace a hot tub pump. 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.
