pump direction on these things reversible in the field, or you gotta pull it apart to swap it?
Answer by: Customer Support on Nov 11, 2025, 5:42 PM
Field reversible is one of the listed features on this pump, so you can change rotation direction without disassembling the unit. That kind of flexibility saves real time when you're fitting it to a machine during installation or swapping it out on a service call.
