Name: SJD-CEP vertical multistage can condensate extraction pump
Brand: Sulzer

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 SJD-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

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 or 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.

Case studies

Sulzer pumps are at the core of geothermal power
April 14, 2021

Together with Sulzer, Italian geothermal power specialist Exergy, has been installing renewable power generation equipment at sites around the world. Their most recent project was the development of a new facility in Turkey. With decades of experience in pump design and engineering, Sulzer has become a preferred supplier of pump technology for geothermal applications. The company has significant experience in the complex design requirements of working fluid pumps, which must be adapted to match the characteristics of different fluid types and operating regimes.
