rotation on this one is clockwise, right? just want to make sure before we pull the trigger on ordering

Answer by: Customer Support on Sep 4, 2025, 6:27 PM

Clockwise rotation is correct for this pump. That said, it's worth double-checking your system's rotation requirement before installation since running the wrong direction in a closed circuit setup can cause real headaches. The CW designation is built into the part itself, so if your system calls for counterclockwise you'd need a different configuration.

What kinda applications does this pump work in? I'm seeing mobile, but what does that really mean?

Answer by: Customer Support on Jun 16, 2025, 6:35 AM

It's suited for mobile environments like you'd find in construction, agriculture, and even some oil and gas applications. Think heavy-duty equipment that moves around a lot.
