The General Pump 47040409 is a 20mm ceramic piston (plunger) for General Pump T, TS and CW series triplex plunger pumps. The white ceramic construction gives excellent chemical and corrosion resistance and a long-wearing sealing surface, and replacing a worn plunger keeps water out of the pump oil.
