SJD (CEP) vertical multistage can condensate extraction pump

Fit-for-purpose condensate extraction pump

SJD (CEP) vertical can condensate extraction pumps, are specified wherever limited NPSH is available, either due to system constraints or liquids operating near to their vapor pressure, typically for condensate extraction and heater drain pump applications. 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
  • Lateral and anti-rotational ribs provide uniform inlet velocity along the can length
Main applications

The SJT (CEP) pumps are vertically suspended, double-casing, bowl diffuser pumps specially designed for condensate extraction and heater drain pump in:

  • Thermal power plants
  • Gas-fired combined-cycle power plants
  • Nuclear power plants
  • Industrial power plants
  • Concentrated Solar Power (CSP) plants
Features and benefits
Cutaway of SJD (CEP)
1. Single suction high Nss (suction specific speed) or double suction low Nss first stage

Reduced net positive suction head required (NPSHR)

2. Replaceable wear ring surface for impellers and bowls

Allows conservation of the running clearances

3. Carbon graphite product lubricated bearing in bowls and columns

Long maintenance-free periods

4. Shaft sealing by single or double mechanical seal with removable seal housing

 Allows servicing throttle bushing without removing the head

 
5. Axial thrust bearing in pump or in motor 

Adaptable to IEC or NEMA motors

6. Cast of fabricated suction and discharge head with separate fabricated driver stand

Allows using one suction and discharge head per pump size

7. Space coupling

Allows servicing the mechanical seal and thrust bearings as needed

8. Provided with lateral and anti-rotational ribs

Uniform inlet velocity along the can length

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 ensure enough Net Positive Suction Head Available (NPSHA). In small power plants, the CEP could also be horizontal end-suction type.

  • 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 ensure enough Net Positive Suction Head Available (NPSHA). In small power plants, the CEP could also be horizontal end-suction type.

  • 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 ensure 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 ensure enough Net Positive Suction Head Available (NPSHA). In small coal and oil captive Power Plants, the CEP could also be horizontal end-suction type.

  • Condensate re-injection pump for geothermal plants
    The condensate re-injection pump re-injects the cold condensate into the geothermal field to renew the resources.
