Finish Thompson AC6HJS1V620B0118 AC6H Stainless Pump End
The AC6HJS1V620B0118 is a Finish Thompson AC6H close coupled pump end built in 316 stainless steel. It is supplied as the pump end, ready to mount on a motor of the matching frame. The wetted parts are 316 stainless steel with 1-1/4 inch by 3/4 inch connections, and the shaft is sealed by a mechanical seal running carbon against ceramic with Viton FKM elastomers.
The build is robust, and service life in practice is decided at the control valve and the suction rather than in the casing. Keep the suction flooded and clear, avoid starting against a dead head, and never let the pump run dry, because the mechanical seal is the part that pays for all three.

Frequently Asked Questions
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.
Q: Should the pump be run against a throttled discharge?
Briefly for control, yes, but a pump run hard against the stop recirculates and heats the fluid around the seal.
