Finish Thompson AC8SJS1V700B0121 AC8S Stainless Pump End
The AC8SJS1V700B0121 is a Finish Thompson AC8S 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, 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: 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.
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.
