Large Diesel Engine Prelube Pump

Ideal for Prelubing stand-by power installations and other large Natural Gas or Diesel gen-sets of any size. They are also used extensively in marine primary power applications. These prelube pumps will run quietly and require zero maintenance.

It is also a great oil or fuel transfer pump. In addition they make great process pumps where constant pressure or constant flow is important. With our self-contained constant pressure regulator and internal bypass, CF pumps can supply several processes running in parallel. Variations for any reason in one process will not affect the performance of any other process running simultaneously. 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.
