Question by: Vince P on Mar 28, 2025, 10:45 AM

pump says it's field reversible, is that something a guy can do without pulling the whole unit off the machine?

Answer by: Customer Support on Mar 29, 2025, 4:03 PM

Field reversible means the rotation direction can be swapped without full removal or specialized shop equipment. On this Series 26 gear pump, that capability is built into the design, so you're not looking at a teardown job every time a circuit change requires different flow direction. It's one of the more practical features on a pump that's going to see use across something like a tractor or a sweeper where setup flexibility matters.

trying to cut down on that hydraulic whine on my equipment, is this pump built any quieter?

Answer by: Customer Support on Nov 8, 2025, 8:43 AM

Reduced noise and vibration is one of the stated features on this Series 26 external gear pump, along with improved volumetric and mechanical efficiency, so it is aimed at running smoother and more efficiently than older or less refined gear pump designs.
