Test results led the manufacturer to replace the rotary-vane pumps’ needle-roller bearings with DP4 plain bearings. Next, it plans to swap out steel-backed bronze frontplate bearings for DP4s.

Designing hydrostatic bearings is more complex than for self-acting types because of the greater number of ... An alternative design is to connect a fluid displacement pump (gear or vane type) ...

Many pump bearings do not reach their theoretical (L10) fatigue life. ... For positive displacement pumps, it helps to establish if ingression or wear is happening on other moving parts besides ...

THE VANE FLEX PUMP CONNECTOR is a compact, efficient solution to reduce turbulence and straighten flow. Combining hydrodynamic planes with a flexible pump connector it exceeds the flow-straightening ...
