Product Questions & Answers

Got a loader backhoe sitting idle cause the pump went out. This a 3.00 CID open circuit piston pump from the 420 Series, right? Just want to make sure before I pull the trigger on ordering.

Yeah, that's correct. The 421AK02121B is a 3.00 cubic inch per revolution pump, which works out to 49cc displacement, and it's part of the 420 Series open circuit piston pump line. Loader backhoes are actually one of the primary applications this pump was built for, so you're in the right place.

Reckon this fella'll work on my old tractor? It's a backhoe loader.

This Danfoss/Eaton open circuit piston pump is well-suited to heavy mobile equipment including loader backhoes and agriculture tractors, so it should be a good fit.
