EP-4 Prelube Oil Pump


The EP-4 pump is designed from the ground up to be the ideal prelube oil pump for diesel and natural gas Engine Prelube. EP4 Diesel Engine Prelube PumpIt performs well with high viscosity oils down to very cold temperatures. As a positive displacement , it will self-prime and is more efficient and quieter than a gear pump.

Description

The EP-4 is powered by a self-contained TENV motor rated for both 12 and 24 Volts DC power systems. 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 to ensure that when the main oil pump is running it cannot spill pressure through the prelube system. By including it in the pump the EP-4 reduces the cost of the prelube system as a whole. These pumps are quieter than a gear design due to their “whisper vane” pump technology.
