OEM Replacement Pump Motor

Many pumps come with a motor pre-installed, so where do you find a replacement when the motor fails? It’s possible to contact the pump OEM and order a replacement, however, you’ll likely find a lower-cost, faster-shipping alternative online, without sacrificing quality. The potential cost savings come from decreasing the number of businesses involved in the motor supply chain and ordering directly from the manufacturer of the motor.

Because of standardized frame sizes, you’ll be able to find a replacement that exactly matches the OEM pump motor specifications. Confirm the below information on the motor nameplate to find a replacement:

  • Horsepower
  • RPM
  • Voltage
  • Frame Size
  • Enclosure
  • Phases
  • Mounting Type

Enter your product specifications on the left side menu on this page to filter your options. This will bring back several options to choose from, with varying prices and lead times.

If you’re unfamiliar with these product specs or need a second set of eyes, contact our expert team for support. We’re available Monday-Friday, 7am-6pm MT by phone or email.

Motors are distributed from Edmonton, Alberta; Toronto, Ontario; and Montreal, Quebec. Most pump motors will arrive within 1-5 business days to postal codes in Canada.

Jet Pump Motors

Similar to a jet engine, jet pump motors create large amounts of pressure. This is where the jet pump motor got its name. The pump generates suction to draw fluid into a chamber. A nozzle transforms the pressure into a high-pressure jet, allowing for efficient movement of fluid. These are different than submersible pumps, as the motor and pump are located at the surface, not submersed in fluid.

When searching for a replacement jet pump motor, confirm if your motor is a deep well or shallow well pump. The deep well pump can transport water from depths up to 200 feet. Whereas shallow well pump motors can transport from depths of up to 25 feet.

Keep in mind, a jet motor should never run dry as it could permanently damage the pump.

These are often used in residential pool pumps, industrial pumps, transfer and circulating pumps, and commercial machinery. Baldor, Century, Nidec (also known as US Motors or Emerson Motors), and Marathon manufacturer trusted jet pump motors used across Canada.

P Base / Vertical Motors

Different manufacturers use different nomenclature, but generally a P base motor will indicate a vertical mount pump motor. Because they are vertical, they’re designed to take high axial load but lower radial load. These are commonly used in irrigation pumps and water treatment. WEG offers a wide selection of vertical pump motors, ranging from 1 – 150 horsepower. Baldor vertical pump motors come in 3 –75 horsepower, but custom orders can be built over 2000 horsepower.

Nidec (US Motors) has the largest selection of any brand with both hollow & sold shaft, Medium & high thrust bearings, their range goes from 5 HP – 2000 HP.

Hydraulic Pump Motors

WEG’s hydraulic pump motors come in 5 horsepower, 7.5 horsepower, and 10 horsepower. These motors work with pumps to convert electrical energy into fluid pressure. These are often used for lifting loads in construction, excavating, and manufacturing applications.

Submersible Pump Motors

Baldor’s submersible pump motors are frequently used in wastewater facilities and are built to be completely submerse in liquid. They use the surrounding effluent to cool the motor. They also offer an immersible line of motors, which are designed with a unique seal system. While these motors are not meant to be continually submersed, they are ideal for applications where flooding could occur.

Close Coupled Pump Motors

What is a close coupled motor? The motor shaft and pump are rigidly connecting in a case. The casing is connected directly to the motor. Vs a frame mounted motor where the motor and pump are mounted on a common base plate, which are most common in higher horsepower applications. The close-coupled option is easier to install because the shaft and casing do not need to be aligned. Its design is compact, making it ideal for a confined plant room. Because an additional coupling does not need to be purchased, this is a lower cost option. However, there is a higher risk of motor damage if the pump seal fails. These pump motors are commonly used in transporting water and hazardous chemicals.

Close coupled pump motors may be categorized as JP or JM. The ‘J’ indicates close coupled and the second letter indicates the type of seal. A JP seal is a packing seal and a JM seal is a mechanical seal. These are not interchangeable so ensure you’ve confirmed which type of seal you need for your pump.

We distribute reputable motor brands including Baldor, Century, Marathon, and WEG, which are all stocked in Canada.
