EP4 Prelube Oil Pumps
The EP4 pump is desiged from the ground up to be the ideal prelube oil pump for large engines, and it is also a great oil or fuel transfer pump 
for limited duty cycle applications. It performs well with high viscosity oils down to very cold temperatures. As a positive displacement pump it will self prime and is more efficient and quieter than a gear pump. Anywhere you need to move oil or fuel around you can do it reliably and safely with an EP4 pump.
The EP4-24 is powered by a self-contained motor running on 24 Volt DC power. The EP4-12 is the same unit running on 12 Volt DC power. Both voltages are capable of pressures in excess of 60 psi (4 bar). These pumps also incorporate a self-contained low loss check valve to prevent backflow. This is a critical component in any prelube system so that when the main oil pump is running it cannot spill pressure through the prelube system. By including it in the pump the EP4 reduces the cost of the prelube system as a whole. They are more quiet than a gear design due to their "whisper vane" pump technology. Call for a trial unit today.
