The EMP Smart Flow® brushless electric oil pump is now available in a cartridge style. This allows for the same premium performance of the OP40 and OP80 oil pumps, but in a smaller, lighter profile that allows for seamless integration with a host housing and eliminates the need for fittings and hoses. 


Compact Design for Integration

The cartridge configuration is designed for direct, seamless integration with OEM manifolds and case housings. It offers efficient packaging, consuming minimal real-estate outside of its host housing while eliminating the need for fittings and hoses.

Available with 12 VDC and 24 VDC electric motors. Brushless, permanent magnet motors are combined with EMP designed motor control electronics to provide a smart, high efficiency, long life pump. Brushless motors have no contacting parts to wear and reduce life. Features include protections against…

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.

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 by varying the duty cycle of the signal.  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.

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

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

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.

EMP pumps can be controlled manually using EMPower Connect™ Service Tool. The software on these pumps can be changed or upgraded in the field using this tool.  History data can be downloaded, includes…
