Optimising systems
and applications as standard

The EMP OP40 Electric Oil Pump is a high performing and reliable cooling component with a large operating range and efficiencies making it suitable for a wide range of vehicles and applications.

High Power Density

The EMP OP40 offers best in class performance with flow capacity up to 4 gpm and discharge pressure up to 100 psi. Efficient mechanical design along with proprietary software allows sub-zero cold start capability.

Self Priming

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

Multiple Port Configurations

Pump head has two sets of suction and discharge ports for ease of installation and plumbing.

Communication Protocols

The EMP OP40 can be controlled through the following communication protocols: On-Off, J1939 CAN, PWM , EMP-Link. EMP-Link and J1939 CAN versions allow two-way communication to support diagnostics. J1939 CAN communications support J1939 messages defined for Secondary OBD Devices. PWM version provides tach-out feedback (RPM). Note: Interim solution requires use of TMC system controller.

Brushless DC Motor and Drive Controller Technology

Available with 12 VDC and 24 VDC electric motors, brushless, permanent magnet motors are combined with EMP designed motor control electronics to provide a high efficiency, long life pump. Brushless motors have no contacting parts to wear and reduce life. Features include locked rotor protection, over temperature protection, over current protection, over voltage protection and reverse battery protection.

Fully Controllable or On/Off 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 a PWM input by varying the duty cycle of the signal. In the absence of a PWM signal the pump will run in a preprogramed default speed and operate in an on/off manner. EMP’s TMC system controller can also be used to add pressure feedback capability or control for multiple pump systems.
