SJD (CEP) vertical multistage can pump for condensate extraction

Fit for purpose pumps for condensate extraction

SJD (CEP) pumps are specified wherever limited NPSH is available, either due to system constraints or liquids operating near to their vapor pressure. NPSH requirements of the pump are met by simply adjusting the length of the pump and can, with the advantage of minimized floor space usage.

SJD CEP Vertical Multistage an Pump for Condensate Extraction
Main benefits
  • Carbon graphite product lubricated bearing in bowls and columns for long maintenance-free periods
  • Removable seal housing allows servicing of the throttle bushing without removing the head
  • Separate fabricated driver stand allows the use of one suction and discharge head per pump size
  • Spacer coupling allows servicing of the mechanical seal and thrust bearing as required
  • Can has lateral and anti-rotational ribs that provide uniform inlet velocity along the can length
Main applications
Condensate extraction and heater drain pumps in:
  • thermal power plants
  • nuclear power plants
  • industrial power plants
  • Concentrated Solar Power (CSP) plants
Main design features
  • Single suction (high Net Suction Specific Speed NSS) or double suction (low NSS) impellers provide high head for first stage
  • Replaceable wear ring surface for impellers and bowls
  • Cast of fabricated suction and discharge head
  • Shaft sealing using a single or double mechanical seal
  • Axial thrust bearing in pump or in motor

Applications
  • Condensate Extraction Pumps for biomass firing applications
    Condensate extraction pump (CEP) for biomass firing
    Condensate extraction pumps (CEP) extract the condensate water from the condenser and pump it through the condensate polishing system and the LP heaters to the de-aerator feed water tank. In medium to large size gas-fired combined-cycle power plants, the CEP are vertical canned type to allow artifical creation of enough Net Positive Suction Head Available (NPSHA). In small power plants, the CEP could also be horizontal end-suction type.
  • Combined Cycle Process CEP
    Condensate extraction pump (CEP) for gas-fired
    Condensate extraction pumps (CEP) extract the condensate water from the condenser and pump it through the condensate polishing system and the LP heaters to the de-aerator feed water tank. In medium to large size gas-fired combined-cycle power plants, the CEP are vertical canned type to allow artifical creation of enough Net Positive Suction Head Available (NPSHA). In small power plants, the CEP could also be horizontal end-suction type.
  • Solar panels in the desert
    Condensate extraction pump (CEP) for solar power generation
    Condensate extraction pumps (CEP) extract the condensate water from the condenser and pump it through the condensate polishing system and the LP heaters to the de-aerator feed water tank. The CEP are vertical canned type to allow the creation of artificial Net Positive Suction Head Available (NPSHA). In small plants, they can also be horizontal end suction type.

    Condensate extraction pump for coal- and oil-fired
    Condensate extraction pumps (CEP) extract the condensate water from the condenser and pump it through the condensate polishing system and the LP heaters to the de-aerator feed water tank. In medium to large size coal- and oil-fired power plants, the CEP are vertical canned type to allow creating artificially enough Net Positive Suction Head Available (NPSHA). In small coal and oil captive Power Plants, the CEP could also be horizontal end-suction type.
