Finish Thompson SP15P-14 SP15 SP15 Self Priming Magnetic Drive Pump End
Finish Thompson supplies the SP15P-14 as a SP15 self priming sealless magnetic drive pump end in polypropylene. It is supplied as the pump end, ready to mount on a motor of the matching frame. The SP casing doubles as a fluid reservoir with a molded gooseneck suction passage, so the pump primes itself without a foot valve and lifts from a tank or sump set below it.
These pumps are straightforward to live with as long as the basics are respected. Keep solids out of the suction and avoid running against a closed discharge, since a decoupled magnet set builds heat quickly and can lose strength permanently. Keep the casing reservoir charged so the pump has fluid to prime from at every start.

Frequently Asked Questions
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.
Q: Can the seal be changed without pulling the pump from the pipework?
On the back pull out models yes, the rotating assembly comes out with the motor and the casing stays bolted in place.
Q: Does stainless construction suit every chemical?
No. Stainless handles solvents, fuels and many process fluids well, but chlorides and strong acids attack it where a lined or thermoplastic pump would not.
Q: What does the impeller trim change?
It sets where the pump sits on its curve, so a smaller trim gives less head and draws less power from the same motor.
