What kind of equipment is this pump actually built for? Got a few different machines on the yard and tryna figure out if it fits what we run.
Answer by: Customer Support on May 11, 2025, 6:18 AM
Loader backhoes, dump truck lifts, ag tractors, mini excavators, crawler dozers, and articulated haulers are all in the confirmed application range for this pump. It also covers material handling trucks, rough terrain forklifts, concrete and asphalt pavers, and feller/bunchers. If you're running any mix of mobile off-road or heavy construction equipment, there's a good chance this fits into that lineup.
