Product Features

Advanced Diagnostics

Intelligent diagnostics help the user understand how the pump and the entire system is operating. The diagnostics can be communicated through SAE J1939 CAN for real time analysis, or diagnostic data can be downloaded using EMPowerConnect service tool and sent to EMP for analysis. This is especially useful for troubleshooting or system development, and dry run detection.
Brushless Motor & Controller
Brushless permanent magnet motors are combined with EMP designed motor control electronics to provide a high-efficiency long life fan. Brushless motors have no contacting parts to wear and reduce life. The WP120 has motors available in 12V and 24V options.

Our controller features include protections against…
- Locked rotors
- Over temperature
- Over current
- Over voltage
- Reverse battery
Custom Communication Options
Our SmartFlow technology allows our line of components to communicate in a variety of styles to meet customer needs.
- J1939 CAN
- On/Off

Sealed and Fully Submersible

EMP pumps are sealed and fully submersible for long life operation when exposed to the elements. Pumps are validated to withstand submersion and direct pressure wash.
Temperature Inputs

EMP electric water pumps have the ability to read external temperature sensors and control speed based on this input. They are also able to broadcast temperatures to the vehicle via SAE J1939 CAN.
High Efficiency, Compact, Quiet

The motor, electronics, and fluid design have been optimized for high efficiency. The end result is the highest possible flow and pressure for a given amount of input power. The design is also packaged to have as small a footprint as possible for the given pump performance and minimize sound output.
Validated in Severe Conditions

EMP water pumps are validated to withstand all field conditions including thermal cycles, salt spray, pressure wash, thermal shock, vibration and shock, electrical transients, ESD, reverse battery and more.
Available Service Tool

EMP pumps can be controlled manually using EMPower Connect™ Service Tool. The software in the pumps can be changed or upgraded in the field using this tool. History data can be downloaded and includes hours of operation, temperature data, voltage data, calibration information, histogram data, and diagnostic fault codes.
