Back pull out pump

A design that allows the wet end (1) of the pump to be left on the piping when the power end (19) and adapter (71) are removed.

Most of these pumps are supplied with an open or semi-open impeller that can be adjusted to the volute from the power end without having to disassemble the pump.

This adjusment is made by turning the adjusting nuts (37) located at the rear of the power end.

All ANSI (American National Standards Institute) pumps are designed this way.
