The EP4 pump is an ideal prelube oil pump for large engines, but it is also a great oil or fuel transfer pump for limited duty cycle applications. It performs well with high viscosity oils. As a positive displacement pump it will self prime but is more efficient and quieter than a gear pump. Anywhere you need to move oil or fuel around you can do it easily and safely with a reliable 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, with a pressure gauge built right into the face to show it. These pumps also incorporate a self-contained low loss check valve to prevent backflow. They are quiet due to their "whisper vane" pump technology, and if they do make noise it's due to a starved suction pipe that is too small. They are so quiet that you can hear the normal rattling sound of cavitation in an inlet starved pump
