�� Laing E10 Spa Circulation Pump — 115V 1-Speed 3/4″ Barb for Sundance & Jacuzzi Spas | 6500-460 Compact, whisper-quiet ECM circulation with dry run protection — the OEM pump for Sundance and Jacuzzi 115V spas ♨️ Product Overview The Laing E10 (6500-460) is a 115V, single-speed, 3/4″ barb circulation pump designed as the OEM circulation pump for Sundance and Jacuzzi spas that operate on 115/120V power. Powered by a highly efficient Electronically Commutated Motor (ECM) with the latest EC technology, this pump delivers 98 watts of performance from only 65 watts of power — consuming 40% less energy than standard induction motor pumps. The E10 is shaftless, seal-less, and leak-proof by design — the magnetically driven open impeller eliminates the shaft seal entirely, meaning there is no seal to leak or replace. The built-in dry run protection automatically protects the motor if the pump runs without water, and the soft start (approximately 3 seconds) reduces stress on electrical components. Weighing only 4 lbs and operating at less than 50 dB, this compact pump fits in tight equipment bays and runs virtually silent during 24-hour continuous circulation. The pump includes a 4-foot power cord with terminated ends (spade connectors) and a mounting bracket, and can be mounted horizontally or vertically (motor end down). The clog-resistant open impeller is dynamically balanced with a carbon bearing for smooth, ultra-quiet operation. The E10 is a direct field replacement for all older Laing SM-909 series pumps, Laing E5 models, and numerous OEM spa brand circulation pumps. ✨ Key Features ✅ ECM Technology — Electronically Commutated Motor delivers 98 watts of performance from only 65 watts of power ✅ Shaftless, Seal-less, Leak-Proof — Magnetically driven impeller — no shaft seal to leak or replace ✅ Dry Run Protection — Built-in electronic protection prevents motor damage if pump runs without water ✅ Soft Start — Approximately 3-second soft start reduces electrical stress ✅ Whisper-Quiet — Less than 50 dB — virtually silent 24/7 operation ✅ Open Impeller — Clog Resistant — Dynamically balanced with carbon bearing for smooth operation ✅ Ultra-Compact & Lightweight — Only 4 lbs — fits in tight equipment bays ✅ Flexible Mounting — Horizontal or vertical (motor end down) — includes mounting bracket ✅ 4′ Power Cord Included — 3-wire with terminated ends (spade connectors) ✅ 40% Less Energy — Consumes 40% less energy than standard induction motor circulation pumps ✅ OEM Sundance/Jacuzzi Pump — Same pump used by Sundance and Jacuzzi at the factory ✅ 1-Year Manufacturer’s Warranty — Full warranty coverage �� Technical Specifications Specification Value Manufacturer Laing (Xylem) Series E10 (Ecocirc) OEM Part Number 6500-460 (Sundance / Jacuzzi) Laing Model E10-NSHNDNN1W-02 (also E10-NSHN1W-19) Laing OEM Number 6050U0015 Pump Type Circulation Pump — Single Speed Motor Type ECM (Electronically Commutated Motor) — 32-bit Horsepower 1/40 HP Input Power 65 watts Performance Output 98 watts equivalent Voltage 115V Frequency 50/60 Hz Amperage 1.6A Flow Rate (Max) 10-11 GPM Connection Size 3/4″ Barb (intake and discharge) Impeller Type Open — magnetically driven — clog resistant Bearing Carbon bearing Seal None — shaftless, seal-less, leak-proof design Wet End Thermoplastic Mounting Horizontal or vertical (motor end down) — bracket included Weight 4 lbs (less than 5 lbs) Noise Level Less than 50 dB Cord ✅ 4′ power cord INCLUDED — 3-wire, terminated ends (spade connectors) Mounting Bracket ✅ INCLUDED Dry Run Protection ✅ Built-in electronic protection Soft Start ✅ Approximately 3 seconds Duty Cycle Continuous — designed for 24/7 operation Warranty 1-year manufacturer’s warranty ⚡ Electrical Requirements Electrical Spec Requirement Supply Voltage 120V Frequency 60 Hz Phase Single Phase Amperage 1.6A Input Wattage 65W Cord 4′ — 3-wire (hot, neutral, ground) — terminated ends (spade connectors) — INCLUDED Motor Type ECM (Electronically Commutated) ⚠️ CRITICAL VOLTAGE WARNING: This is a 115/120V pump ONLY. Most Sundance and Jacuzzi spas operate on 230V — verify the voltage on your existing pump label before ordering. Sundance uses the same white/black/green wire colors for both 115V and 230V systems — wire color does NOT indicate voltage. For 230V Sundance/Jacuzzi spas, use part number 6000-125 instead. ⚠️ IMPORTANT ELECTRICAL SAFETY: All electrical installations must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and local building codes. Hot tubs require GFCI (Ground-Fault Circuit Interrupter) protection. A dedicated circuit is required — do not share with other appliances. �� Compatibility Guide Sundance Spa Models — Confirmed Compatible (115V Only) Sundance Model Years Notes 780 Dover 2008 – Mid 2009 115V models only Metro 2006 – 2007 115V models only Solo 2006 – 2007 115V models only Caprio 2006 115V models only 850E Series (all) 2005 115V models only Lagunas (all) 2003 – 2005 115V models only Portofino Series (all) 1999 – 2004 Tango, Metro, Caprio — 115V models only Jacuzzi Spa Models — Confirmed Compatible (115V Only) Jacuzzi Model Years Notes J-210 2002 115V models only J-310 / J-315 2002 115V models only J-320 / J-325 2002 115V models only ⚠️ 115V Only: These compatible models are specifically the 115V versions.

If your existing pump has an SM-909 part number, this E10 is the correct replacement. Original SM-909 Model Cord Length This E10 Replaces It SM-909-NHW-14 14″ cord ✅ Yes SM-909-NHW-18 18″ cord ✅ Yes SM-909-NHW-26 26″ cord ✅ Yes SM-1212-NHW-26 26″ cord ✅ Yes �� Cord Length Note: The E10 comes with a 4-foot (48″) cord. Older SM-909 models had shorter cords (14″, 18″, 26″). The E10’s longer 4′ cord provides more flexibility for installation. If the cord is too long, excess can be managed; if your original was very short, the E10’s longer cord is an advantage. �� Alternate Part Numbers Primary Part Numbers Part Number Notes 6500-460 Sundance / Jacuzzi OEM part number (THIS PUMP) 6500-460NA North American variant designation E10-NSHNDNN1W-02 Laing model number E10-NSHN1W-19 Laing newer model revision E10-NSHNDNN1W-01 Laing earlier revision E10-NSHNNN1W Laing variant E10-NSHNNN1W-19 Laing variant 6050U0015 Laing OEM manufacturer number Sundance / Jacuzzi OEM Cross-References Part Number Notes 6500-038 Jacuzzi J-300 series 115V circ pump — this pump replaces it SD6500-460 / SD6500460 Alternate format for 6500-460 SD6540-460 Alternate format variant SUN6500-460 Sundance branded variant Alternate Format / Distributor Part Numbers Part Number Brand / Notes SD6500-4610-0120M-K Combined reference number HQ100120MK / HQ100120M HydroQuip format 10-0120 / 10-0120M-K HydroQuip catalog number 34-158-1450 Industry cross-reference 1-00-0136A / 1-00-0136 Industry cross-reference 1-00-0164 / 1-00-0173 / 1-00-0177 Industry cross-reference variants LAI-10-116 Distributor reference LHB07100139 Catalog reference LHB07100169 Catalog reference variant A-05-280-502 Alternate reference EL-64104-1 / 5EL-64104-1 Alternate reference 3WY87 Dayton cross-reference Older Laing SM-909 / SM-1212 Models This Pump Replaces Part Number Description SM-909-NHW-14 / SM909NHW-14 Laing SM-909 with 14″ cord, 3/4″ barb SM-909-NHW-18 / SM909NHW-18 Laing SM-909 with 18″ cord, 3/4″ barb SM-909-NHW-26 / SM909NHW-26 Laing SM-909 with 26″ cord, 3/4″ barb SM-1212-NHW-26 / SM1212NHW-26 Laing SM-1212 with 26″ cord, 3/4″ barb SM-909-NH-14 / 909-NH-14 Earlier designation SM-909-NH-18 / 909-NH-18 Earlier designation SM-909-NH-26 / 909-NH-26 Earlier designation SM-909-NH-14-2 Variant SM909NH Generic SM-909 reference SM-909 / SM-303 Generic references Laing Numeric Cross-References Part Number Notes 73989 Laing reference 73979 Laing reference 73349 / 73369 Laing references 73491 / 73588 Laing / Watkins references 6848 Corresponds to 909-NH-14 6860 Corresponds to 909-NH-26 6865 Corresponds to 909-NH-18 6958 Corresponds to 1212-NH-26 6846 / 6650 / 6487 / 6496 Older Laing references Other Laing Model Cross-References Part Number Notes 6080U0007 / 6080U0027 / 6080U007 Laing model variants 611064 / 611123 Laing references 9332-0 / 9336-0 / 9338-0 / 9338-10 / 9339-15 Laing catalog numbers LAISM909NH14/12 / LAISM909NH142 Combined Laing/SM references LAISM909NH1834 / LAISM909NH26120 Combined Laing/SM references LAISM1212NH2612 Combined Laing/SM-1212 reference Watkins / Hot Springs / Caldera Cross-References Part Number Notes Watkins 37949 / 34378 / 73491 Watkins brand references Watkins 301392 / 1039801 Watkins brand references SilentFlo 5000 Watkins branded pump name Additional OEM Cross-References Part Number Notes 6603.9 / 6355.9 / 6425.9 / 6596.9 / 7385.9 SpaAndPoolSource cross-references 242059808 Alternate reference LTI 7060 / LTI 70813 / LTI 73588 / LTI 73989 / LTI 73369 LTI brand references Grundfos Replacement Alternative Part Number Notes 10-0139-KIT Grundfos 3-speed universal kit (115V) — can replace this Laing E10 10-0139-K Grundfos pump with adapters (115V) 99575701P1 Grundfos newer universal kit (115V) LX Lower-Cost Alternative Part Number Notes WE10-120V LX brand — same performance and function — lower cost alternative ��️ Installation Requirements What’s in the Box Item Notes Laing E10 circulation pump Complete pump assembly 4′ power cord 3-wire, terminated ends (spade connectors) Mounting bracket For plate mounting Mounting Requirement Specification Mounting Position Horizontal OR vertical (motor end down) Mounting Method Plate mounted — bracket included Base Solid, stable surface Access Allow clearance for cord connections and maintenance Plumbing Connection Size Notes Intake 3/4″ barb Connects to 3/4″ ID vinyl tubing Discharge 3/4″ barb Connects to 3/4″ ID vinyl tubing Tubing 3/4″ ID clear vinyl tubing Secure with hose clamps Installation Notes ⚠️ Verify Voltage First: Confirm your existing pump operates on 115V/120V — NOT 230V. Check the label on your old pump. Most Sundance/Jacuzzi spas use 230V. ⚠️ Wiring: 3-wire connection — hot, neutral, ground. Cord terminates with spade connectors. ⚠️ First Startup: The pump has a soft start (approximately 3 seconds). The impeller may rotate slowly at first until water penetrates the bearings — this is normal. ⚠️ Dry Run Protection: Built-in electronic protection activates if pump runs without water. However, always ensure pump is primed and submerged below water level before startup. ⚠️ Mounting Orientation: Horizontal or vertical with motor end DOWN only. Do not mount with motor end up. ⚠️ SM-909 Replacement: If replacing an SM-909, the E10’s 4′ cord is longer than the original SM-909 cords (14″-26″). Route excess cord safely. ⚠️ GFCI Protection Required: All spa installations require GFCI protection per the NEC. ⚠️ Bonding & Grounding Required: Per NEC requirements. ⚙️ Maintenance Guide Routine Maintenance Task Frequency Notes Check for water flow Monthly Verify circulation is active Inspect barb connections Monthly Check for leaks at hose clamp connections Listen for unusual noise Monthly Should be nearly silent (less than 50 dB) Inspect cord and connections Quarterly Check spade connectors and cord condition Check mounting bracket Quarterly Ensure pump is secure Verify GFCI operation Monthly Test button check Warning Signs — Replace Pump If: Pump fails to start or hums without rotation Unusual noise (clicking, grinding, buzzing) No water circulation despite pump running Motor trips breaker or GFCI repeatedly Pump vibrating excessively Dry run protection activating frequently (indicates plumbing issue) Error codes on spa controller related to circulation (FL1, FLO, etc.) Seal-Free Design Advantage Unlike traditional circulation pumps with mechanical shaft seals, the Laing E10 uses a magnetically driven impeller — there is no shaft seal to leak, wear, or replace. This eliminates one of the most common failure points in spa pumps. If you see water leaking from this pump, it indicates a cracked housing or failed barb connection — not a seal issue. �� Ideal Applications Application Suitability Notes ♨️ Sundance 115V spa circulation ✅ Yes — OEM replacement 780 Dover, Metro, Solo, Caprio, 850E, Lagunas, Portofino ♨️ Jacuzzi 115V spa circulation ✅ Yes — OEM replacement J-210, J-310/315, J-320/325 (2002 ) ♨️ Dimension One 115V circ pump ✅ Yes — Confirmed Select 115V models ♨️ Tiger River circ pump ✅ Yes — Customer confirmed Caspian and other 115V models ♨️ SM-909 series replacement ✅ Yes — Direct upgrade All SM-909-NHW and SM-1212-NHW models ♨️ Any 115V spa with 3/4″ barb circ pump ✅ Yes — Universal fit Same voltage and connection type ♨️ Sundance/Jacuzzi 230V spas ❌ No — Wrong voltage Use 6000-125 (230V) instead ♨️ Spas with 1″ barb connections ❌ No — Wrong size Need 1″ barb version or adapters ♨️ Spas with 1-1/2″ MBT threaded connections ❌ No — Wrong type Barb connections only ❓ Frequently Asked Questions Q: Is this the right pump for my Sundance spa? A: Only if your Sundance spa uses a 115V/120V circulation pump with 3/4″ barb connections. Most Sundance spas use 230V — check the voltage label on your existing pump. If your spa is 230V, you need part number 6000-125 instead. Q: How do I know if my spa uses 115V or 230V? A: Check the label on your existing circulation pump — it will show the voltage. Do NOT rely on wire colors — Sundance uses white/black/green wires for both 115V and 230V systems. Q: Will this replace my Jacuzzi J-300 series circulation pump? A: Yes — for 115V Jacuzzi J-300 models (J-310, J-315, J-320, J-325) made after 2002. This pump also replaces Jacuzzi part number 6500-038. Verify 115V before ordering. Q: Does this pump have a shaft seal that can leak? A: No — this is a key advantage of the Laing E10. The impeller is magnetically driven — there is no shaft seal to leak, wear, or replace. The pump is shaftless, seal-less, and leak-proof by design. Q: Does this pump have dry run protection? A: Yes — built-in electronic dry run protection activates automatically if the pump runs without water, preventing motor damage. Q: Is a cord included? A: Yes — a 4-foot power cord is included with 3-wire terminated ends (spade connectors). A mounting bracket is also included. Q: Can I mount this pump vertically? A: Yes — the E10 can be mounted horizontally or vertically with the motor end facing down. Do NOT mount with motor end up. Q: Will this replace my old SM-909 pump? A: Yes — the Laing E10 is the current-production field replacement for all discontinued SM-909-NHW and SM-1212-NHW series circulation pumps with 3/4″ barb connections. Q: How quiet is this pump? A: Very quiet — rated at less than 50 dB. Customer reviews consistently describe it as whisper-quiet and nearly silent during 24/7 operation. Q: What is the flow rate? A: Maximum approximately 10-11 GPM depending on plumbing conditions. This is sufficient for low-flow heater circulation and filtration in most spas. Q: Is there a Grundfos alternative? A: Yes — the Grundfos 10-0139-KIT (115V, 3-speed, universal kit) is designed as a universal replacement for this Laing E10 and includes a complete plumbing kit with 3/4″ and 1″ barb adapters. Available separately at Parts4Tubs. Q: Is there a lower-cost alternative? A: Yes — the LX WE10-120V offers the same performance and function at a lower price point. Contact Parts4Tubs for availability. Q: Do I need a GFCI breaker? A: Yes — GFCI protection is required by the NEC for all hot tub and spa installations. Q: What warranty is included? A: 1-year manufacturer’s warranty. Contact Parts4Tubs for full terms. �� Why Choose the Laing E10 6500-460 ✅ OEM Sundance/Jacuzzi Pump — Same pump used at the factory — guaranteed compatibility for 115V spas ✅ ECM Motor Technology — 98 watts of performance from only 65 watts — 40% more efficient than induction motors ✅ Seal-Less, Leak-Proof Design — Magnetically driven impeller — no shaft seal to leak or replace ✅ Built-In Dry Run Protection — Electronic protection prevents damage if pump runs without water ✅ Whisper-Quiet — Less than 50 dB — nearly silent 24/7 operation ✅ Compact & Lightweight — Only 4 lbs — fits in the tightest equipment bays ✅ Clog-Resistant Open Impeller — Dynamically balanced with carbon bearing ✅ Flexible Mounting — Horizontal or vertical (motor end down) ✅ 4′ Cord & Mounting Bracket Included — Everything needed for installation ✅ Soft Start Technology — 3-second soft start reduces electrical stress ✅ Replaces All SM-909 Models — Direct upgrade from discontinued SM-909/SM-1212 series ✅ Proven Reliability — Laing (Xylem) — world-renowned pump manufacturer ✅ 1-Year Manufacturer’s Warranty — Full warranty coverage �� Why Buy From Parts4Tubs ✅ Fast shipping across the United States ✅ Expert advice from spa and hot tub specialists ✅ Competitive pricing ✅ Full warranty support ✅ Hassle-free returns ✅ Replacement parts, vinyl tubing, and barb fittings available ✅ Dedicated customer service team ⭐ Summary The Laing E10 (6500-460) is a 115V/120V, single-speed, 3/4″ barb circulation pump and the OEM replacement for Sundance and Jacuzzi 115V spas including 780 Dover, Metro, Solo, Caprio, 850E, Lagunas, Portofino series, and Jacuzzi J-210/J-310/J-315/J-320/J-325 (2002 ).
