Tested & Reprogrammed Used Stewart/EMP WP29 High Output 12V Electric Water Pump

Description:

• Used Stewart / EMP WP29 electric water pump that has been inspected and flow tested

• 12V operation

• Can  be used as an intercooler pump, engine coolant pump, auxiliary coolant pump, EV battery circulation pump and many other uses

• One of the highest flowing, high pressure electric water pumps available

  • This pump is designed to operate at high differential pressures

• High flow and high pressure capability

  • Flows over 29 gallons per minute (gpm) at 7 psi pressure

  • This pump will flow continue to flow at over 25 psi differential pressure

    • Flows over 6 gpm at 26 psi (most pumps will have long since stopped flowing at these pressures)

  • Don't be fooled by flow claims from other pumps that show the open to atmosphere peak flow. Make sure you compare flow at the flow restriction that exists in your cooling system.

• High current, high efficiency DC brushless electric motor
• Long life design (10,000+ hour target lifespan)
• 1" inlet and outlet connection fittings
• Cast 413 aluminum alloy housing
• 9-18 volt DC operating range
• Variable speed capability via J1939 (requires CAN input to pump)

Configuration:

• This pump has been programmed for a maximum current limit of 25 amps and a maximum pump speed of 4600 RPM. That is the maximum performance capability of this pump.
• The pumps are configured to operate via external CAN control or stand-alone.
• In the absence of a CAN signal, the pump will behave as a simple on/off control pump.
  • The built-in pump controller will wait 0.1 seconds on initial start to check for the CAN signal. When the pump controller does not see the CAN signal for 0.1 seconds it will then go into stand-alone operating mode (simple on/off control mode).
  • In stand-alone operating mode the pump operates at the default speed of 4600 rpm (maximum rpm)
  • Need different settings programmed in the pump - contact us so we can see if we can provide what you need

• EMP (Stewart Components)

• WP29 (also referred to as E2512A or WP32)

• 1030002286P0020 rev B

Included:

• Pump
• 60" power, ground and activation wire pigtail harness
• Communications port plug
  • CAN control harness NOT included. Available separately. Pump is programmed to default to maximum pump speed so a CAN connection is not needed for on/off type control.

Condition:

• Used
• Pump has been tested to verify flow and pump operation. Pump has been run on our test stand for a minimum of 30 minutes (with fluid - NEVER run intercooler pumps dry)
• Pump has been reprogrammed for maximum flow without external CAN inputs required. Label with settings part number and date applied to pump to document current pump status.
• Pump has been flow tested to verify flow rate and operation.
• Run-time counter has been reset to 0 hours
• Note - we have multiple pumps. The images shown are for reference example and will not be of the actual pump you will receive. Pumps are inspected for damage but they are used pumps and will have some signs of wear/use.

Warranty:

• 90 days or 500 operating hours (run-time stored in pump)
• Repair or replace at PSS discretion
• Warranty void if maximum operating temperature or voltage is exceeded.
• Warranty void if allowed to operate dry (with no fluid) or other installation requirements not followed
• Buyer responsible for shipping in both directions

Returns:

• 30 days with no sign of use or damage
  • Buyer responsible for return shipping and all parts must be returned

Country of origin:

• Made in the USA
