• 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. 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.

Consequently, the shaft is not exposed to corrosion by condensate. Rated for temperatures up to 250°F.
• Isolation Valve (B) : Standard on 5000-JF Series
• Centrifugal Pump (C) : Offers a wide range of pressures and GPM. Unique design features provide for ease of servicing.
