High Power Density

OP series offers best-in-class performance for flow capacity and operating pressure. Efficient mechanical design along with proprietary software allows sub-zero cold start capability.
Fully Controllable or Single Speed

EMP pumps can be run at any speed between the programmed minimum and maximum speed to minimize power consumption and noise. Variable speed can be achieved through CAN speed command or PWM input. In the absence of CAN speed command or PWM signal the pump will run a preprogrammed default speed and operate in an on/off manner.
Positive Displacement Design

EMP pumps feature positive displacement gerotor type pumping elements, allowing for simpler, quieter, more compact pump design while improving performance and minimizing power loss.
Self-Priming

EMP pumps are all 100% flow tested and incorporate internal geometry features to ensure the pump will remain wet for improved priming capability.
Sealed and Fully Submersible

EMP pumps are sealed and fully submersible for long life operation when exposed to the outside environment and its elements. The pumps are designed and have been validated to withstand submersion and direct spray pressure wash.
Multiple Port Configuration

Oil pump heads have two sets of suction and discharge ports to offer flexible integration.
Service Tool
EMP pumps can be controlled manually using EMPower Connect™ Service Tool. The software on these pumps can be easily changed or updated in the field using this tool. History data can be downloaded, which includes…
- Hours of operation
- Temperature data
- Voltage data
- Calibration information
- Diagnostic fault codes
- Performance data
Variety of Applications
The OP series can be utilized in a variety of functions, customized to the needs of our customers.
- General oil transfer
- Lubrication
- Cooling
- Oil scavenging
- Oil change
- By-pass filtration
