Product Questions & Answers

Got a Commercial G102-2-20L on my medium duty dump truck right now and it's about shot. This pump a straight swap for that?
Question by: Jean C on Aug 25, 2025, 5:51 PM
Yeah, the DM400 series directly replaces the Commercial G102-2-20L, so you're not looking at any major rework to get it in place. It's a direct mount configuration running 3-line operation, with a 1-1/4 NPT inlet, 3/4 NPT pressure port, and 3/4 NPT return port. Rotation is counterclockwise, so just confirm that matches your current setup before you bolt it on and you should be good to go.

got a commercial G102-2-20L on my truck now, is this Permco pump a straight replacement or am i gonna be re-hydraulic connections stuff
Question by: Phil M on Jul 16, 2025, 9:11 AM
It’s called out as a replacement for the Commercial G102-2-20L. It’s a direct mount, 3-line dump pump with a 1-1/4 NPT inlet, 3/4 NPT pressure port, and a 3/4 NPT return port for the third line, so it matches that style of hydraulic connections.
