EP4 Prelube Oil Pumps

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. OEM pricing also available.EP4-24 Features and Specifications Self-contained motor Rated for 24vdc (Not for Continuous Duty) 4 GPM (15 LPM) flow rate Pressures in excess of 60 psi (4 bar) Integrated low loss check valve Built in gage on face of pump to verify pressure Whisper-Vane positive displacement vane technology Suction port SAE straight thread O-ring size: 3/4" Discharge port SAE straight thread O-ring size: 3/4" Designed for 500 - 3000hp diesel engine applications EP2-12 Features and SpecificationsSelf-contained motor Rated for 12vdc (Not for Continuous Duty) 1.75 GPM (6.62 LPM) flow rate Pressures in excess of 60 psi (4 bar) Integrated low loss check valve Built in gage on face of pump to verify pressure Whisper-Vane positive displacement vane technology Suction port SAE straight thread O-ring size: 3/4" Discharge port SAE straight thread O-ring size: 3/4" Designed for 400 - 800hp diesel engine applications Feature and Specifications Comparison EP4-24 EP4-12 Operating voltage 24vdc 12vdc Flow rate 4 GPM(15 LPM) 1.75 GPM(6.6 LPM) Attainable pressure 60psi(4 bar) 60psi(4 bar) Integrated low loss check valve Y Y Built in gage on face of pump to verify pressure Y Y Whisper-Vane positive displacement vane technology, Self Priming Y Y Suction port SAE straight thread O-ring size: 3/4" 3/4" Discharge port SAE straight thread O-ring size: 3/4" 3/4"
