Finish Thompson GP22PEB016018 GP22 Pump End
Finish Thompson supplies the GP22PEB016018 as a GP22 sealed centrifugal pump end in polypropylene. It is supplied as the pump end, ready to mount on a motor of the matching frame. The wetted parts are polypropylene with 2 inch connections, and the shaft is sealed by a mechanical seal rather than a magnetic coupling, which is what lets this range handle duties beyond the reach of a sealless pump.
These pumps are straightforward to live with as long as the basics are respected. Keep the suction flooded, avoid dead heading, and never start the pump dry, because the mechanical seal is what pays for any of the three.

Frequently Asked Questions
Q: How important is alignment on a close coupled pump?
The motor and pump share a machined register, so alignment is fixed at assembly and the register faces must be clean and undamaged.
Q: What is the first sign of seal trouble?
A trace of product at the drain below the adapter, usually intermittent at first and always worse under pressure.
Q: Does the pump need a suction strainer?
It is good practice on any close clearance pump, and essential if the system has been newly built or recently opened.
Q: What limits the life of the mechanical seal?
Dry running above all, then thermal shock and solids working between the faces. A seal that has run dry rarely recovers.
