Pennant Condensate Recovery System-pcp

The Pennant condensate pump (PCP-10) is an excellent alternative to standard electric pumps which are not suitable for pumping hot condensate. It is a complete non-electric solution designed to lift condensate to the boiler feed-water tank, using small quantities of motive steam/air.

FEATURES

  • Intrinsically safe for use in hazardous areas since there are no electric connections 
  • Works in remote areas where electric supply is not available 
  • Not prone to wasteful leaks as there are no rotating parts with mechanical seals
  • All stainless steel internals give excellent corrosion resistance for long trouble-free service
  • Exceptionally low cost of operation and maintenance
Sizes

25 x 25, 40 x 40, 50 x 50, 80 x 50, 100 x 100

End Connections
  • Flanged #150, #300 as per ASME B16.5
  • Screwed (NPT/BSPT/BSP)

Typical Configuration

  • Stand Alone Unit: A stand-alone unit consists of a pump tank, inlet-outlet check valves & internal pumping mechanism. 
  • Pump with Receiver Tank: In this configuration, there can be multiple pumping units, all fed from one receiver tank. The entire assembly is mounted on a common base. 

Depending on the number of pumping units, these are classified as,

  1. Simplex: One pumping unit with check valves and one receiver tank skid-mounted 
  2. Duplex: Two pumping units with check valves and one receiver tank skid-mounted 
  3. Triplex: Three pumping units with check valves and one receiver tank skid-mounted

OPERATING PRINCIPLE

Liquid to be pumped enters the condensate pump tank via the inlet check valve–the vent valve is open and the steam/air valve closed. As the liquid level rises in the tank, the float rises. When the liquid level reaches its ‘high level’, the compression spring simultaneously forces the vent valve to close and motive steam/air (pressure) valve to open. The pressure forces the liquid through the exit check valve. During the pumping cycle, the float drops as the liquid level recedes to the ‘low level’. The action of the compression spring then simultaneously forces the vent valve open and the motive steam/air valve closed. Pressure in the pump tank is released through the vent, and liquid to be pumped enters through the inlet check valve repeating the cycle.
