Manufacturer:
Sterling
Description:

Unit: Completely factory assembled and tested. Simplex units have one receiver, one make-up water valve, and one vertical pump and motor assembly. Duplex units have 2 vertical pumps. All units are supplied with a gauge glass on the side of the receiver and a flat perforated brass strainer at the inlet to the pump. Motors: Heavy-duty, ball bearing, close-coupled pump motors with stainless steel shaft. 3450 RPM for greater efficiency and more economical operation. Make-up Water Valve: Mechanical, plug mounted valve with stainless steel float. Rated up to 45 PSI inlet water pressure. Receiver: Heavy-gauge steel construction. All receivers of 45 gallon size and larger are supplied in duplex design, with one pump opening covered when a simplex design is specified. Operation: Boiler feed pump(s) are controlled by a water level controller mounted on the boiler. If condensate is lost or delayed in the system, it is automatically replaced in the receiver through the make-up water valve. "SterlSeal" Pump Seal (A): Features the ultimate in ceramic technology for exceptionally long life. Because the seal runs on the bronze impeller hub, the motor shaft is literally outside the pump. Consequently, the shaft is not exposed to corrosion by condensate. Rated for temperatures up to 250°F. Isolation Valve (B): Optional on 4100 Series Boiler Feed Pumps
