Pre-lube / post-lube oil pump

摘要

This company has released a second EP4 Pre Lube pump in its industrial pump line. With a dual voltage, permanent magnet, 12 or 24 Vdc motor, the EP4 is appropriate for engines to 3,000 hp. It provides lubrication prior to starting reciprocating engines and compressors by drawing oil directly from the crankcase and delivering it back to the bearings until the main oil pump starts running and takes over. As a post lube, it delivers oil to the turbo bearings as they spin down and cool.
