Question by: Pete S on Feb 7, 2026, 3:24 PM
trying to match up what i’ve got now. is this the 30VQ28A-1C20 pump with a 7/8 straight keyed shaft and clockwise rotation?
Answer by: Customer Support on Feb 8, 2026, 9:42 PM
Match it up to the model number and the key details. This unit is model 30VQ28A-1C20 in the 30VQ series, it has a 28 ring size, a 7/8 straight keyed shaft, and it is CW rotation.
Question by: Phil B on Sep 23, 2025, 1:37 PM
got a 30VQ28A-1C20 on an old press unit and need to know if this is the right replacement before I order, shaft size and rotation match up?
Answer by: Customer Support on Sep 24, 2025, 6:37 PM
For a direct swap on that model, you're looking at a 7/8 straight keyed shaft and clockwise rotation, with the outlet running in-line with the inlet. Ring size is 28. If your existing pump matches those details, this one lines up as a replacement. Displacement comes in at 5.5 and rated flow is 42.85, so confirm those numbers work for your press circuit before pulling the trigger.
