Question by: Warren B on Apr 4, 2026, 6:08 AM
What kind of applications is this Vickers pump best suited for?
Answer by: Customer Support on Apr 5, 2026, 9:19 AM
This vane pump works well in power steering systems, smaller industrial units, and small presses.
Question by: Lyle H on Apr 6, 2026, 12:38 PM
What kind of seal does this pump use, and is that gonna hold up in a standard hydraulic system running regular petroleum-based fluid?
Answer by: Customer Support on Apr 7, 2026, 3:46 PM
Buna-N seals are what's in this pump, and they're a solid match for standard petroleum-based hydraulic fluids. That's pretty much the go-to seal material for most conventional hydraulic setups, so compatibility there isn't something you'd need to lose sleep over in a typical industrial application.
