Pulling For A New Approach
Three screw pumps are commonly used as lube oil pumps for compressors, gearboxes, turbines and other rotating equipment. Their popularity stems from the efficient, reliable and long-lasting service they provide.
While most lube oil pumps are only exposed to ambient pressure at the pump inlet port, there are some applications where the pump sees high inlet pressures.This poses a huge challenge for the pump seal solution and pump construction. In many pump designs it can also lead to high bearing and seal loads that negatively affect the pump and seal life.
