Product Questions & Answers (2)

Question by: Neal H on Mar 29, 2025, 6:17 AM
got a small press setup running a Vickers vane pump and trying to figure out if this double unit would drop right in, it's a 2-bolt SAE B mount with a 13T splined shaft, that right?
Answer by: Customer Support on Mar 30, 2025, 7:43 PM
Both of those check out. The mounting flange is 2-bolt SAE B and the shaft is a 13T SAE B splined configuration, so if your existing setup matches those specs, the physical fit should line up. Port connections are SAE 4-bolt flange style, with a 2-1/2 inch inlet, a 1-inch front outlet, and a 3/4-inch rear outlet, so factor those into your hydraulic connections before swapping it in.
Question by: Clint M on Aug 8, 2025, 3:35 PM
Reckon this'd be alright for a small press application, like the description says?
Answer by: Customer Support on Aug 9, 2025, 6:45 PM
For small press setups, yes, this hydraulic double vane pump is well-suited, especially given its front and rear displacement volumes.
