Been rebuilding a 5100 series pump and need to replace the housing. This the right part for a 2-3/4 unit?

Question by: Harold B on Apr 29, 2025, 7:26 AM

For a 2-3/4 5100 series Permco gear pump or motor rebuild, this is the correct housing. It's manufactured to Permco's own dimensional standards, so it drops in as a direct replacement without any modification or fitting work. Part number is LZ-0577-20D if you want to cross-check it against your existing component before ordering.

got a permco 5100 pump im rebuilding, is this the housing that actually holds the gear set?

Question by: Todd W on Dec 22, 2025, 9:08 AM

In a 5100 series gear pump or motor, the 2-3/4 housing is the main structural piece that encloses and supports the internal gear set as part of the assembly.
