The Spence Condensate Recovery Pump Trap is a pressure-operated pump primarily intended to trap steam and pump condensate depending on the pipeline conditions without the use of electricity. The stainless steel snap-acting mechanism in continuous compression is unaffected by turbulence and the single spring assures long service life without adjustment. The Condensate Recovery Pump Trap is used in different applications. This pump can be used with a vented receiver, with an inlet receiver, in a submerged application, or in a skid-mounted system. The cast iron body size 1-1/2 x 1 NPS NPT connections allow for ease of installation with a max operating pressure at 200 PSIG.
