Sterlco 503700-SDF Standard Product Features:
- Heavy Gauge Steel Receiver: Heavy gauge stainless steel construction. Sizes ranging from 12.5 gallons up to 714 gallons.
- Simplex or Duplex Motors: Heavy-duty, ball bearing, close-coupled energy efficient motors with stainless steel shaft. 3450 RPM for greater efficiency and more economical operation.
- Bronze Fitted Centrifugal Pump: Offers a wide rand of pressures and GPM. Unique design features provide for ease of servicing.
- Energy efficient 3450 RPM motors
- “Sterl-Seal” Pump Seal: 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 250ºF.
- Heavy Duty Make-up Water Valve: Mechanical, plug mounted valve with stainless steel float. Rated up to 45 PSI inlet water pressure. At pressures exceeding 45 PSI, a PRV is required on the inlet cold water line.
- 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.
- Isolation valve (B): Standard on 5000-JF Series. Allows removal of pump without draining the tank.
- Gauge Glass
- Accessories: Wide range of options and accessories
