Boiler Feed Water Pump Installation

Boiler Feed Water Pump Installation 


  1. Care must be taken not to damage the unit during uncrating. 2. When using pry bars or forklifts, support the Feed System weight on its channel base only. 3. Storage: Electrical equipment can be damaged if exposed to adverse weather. The Feed System must be stored inside. The electrical panel and controls must be covered in plastic throughout all construction to avoid accumulation of dust and moisture.


  1. Installation must comply with all Federal, State and local codes.

  2. Locate unit to provide easy access for inspection and maintenance.

  3. Provide a firm, level foundation for the feed system, preferably a raised, concrete “housekeeping” pad.

  4. Leave a permanent access space of 30 inches opposite the float level control, the sparge tube/temperature control valve (where applicable) and the pump(s) location. Leave a 36-inch access space opposite the control panel.

  5. Once the feed system is in place, level it using shims as required and secure with foundation bolts. If desired, the unit may be grouted in place.

  6. Under no circumstances should anyone climb on the feed system. Climbing may result in damage to the unit or may result in a fall, resulting in serious injury or even death.


  1. Boiler piping connections and valves MUST comply with State and local codes and, where required, ANSI and ASME Boiler and Pressure Vessel Code piping requirements.

  2. Pipe the vent connection full size to outdoors. Make provisions to prevent entry of rain and/or snow.

 3. Pipe the feedwater supply line to the boiler. Be sure to include a manual isolation valve and check valve in this line. The check valve should be closest to the feedpump. 

 4. Pipe the make-up water supply line to the the float-feeder connection. Be sure to include a manual isolation valve in this line and verify that the line pressure does not exceed the allowable shutoff pressure of the make-up valve. 

 5. (On units with steam sparge preheater) Plumb the steam line to the steam temperature control valve. Be sure to include a manual isolation valve in this line. 

 6. Pipe the overflow line to a safe drain. 7. Pipe the system condensate return line to the marked connection on the tank. 8. Pipe the drain line from the drain valve mounted on the unit to a safe drain
