Boiler Feed Pumping and Feed Units

Boiler Feed Series VCMD

Domestic Pump Series VCMD is a combination vacuum and boiler feed unit that offers a wide selection of cast iron, steel, and underground boiler feed receivers in conjunction with the dependable water jet vacuum units.

The vacuum unit can be mounted on the boiler feed unit to conserve floor space or be furnished separately.  Individually sized and separately controlled vacuum and water pumps permit maximum flexibility to meet boiler feed applications where vacuum is required.  The boiler feed  pumps are controlled by a dedicated pump control on the boiler (available as optional) responding to water level change in the boiler. This maintains optimum steaming level in the boiler for maximum performance and safety.  The VCMD is available in simplex, duplex and triplex configurations. Additional pumps are available on request. Water make up uses a Float switch and Solenoid valve with “Y” strainer to add make-up water on low level.  Tempering the added cold water with the hot condensate in the receiver minimizes the danger of thermal shock to the boiler.
