Sulzer Pumps

SJD (CEP) Vertical Condensate Extraction Pumps

Introduction

The SJD (CEP) pumps are vertically suspended,double casing (canned), bowl diffuser pumps.

These pumps are specially designed for condensateextraction service in power plants to meetthe low NPSHa criteria (API requirements are notapplicable).

There are two distinct designs for the CEP pumps.

← Pumps designed for 50Hz combined cycle plants

and

Pumps designed for 60Hz coal fired plants →


Sulzer Pumps

Single Suction First Stage Design

These CEP pumps are intended for application in 50Hz combined cycle power plants.

The pump is designed with a single suction, high NSS, first stage impeller. Thus resulting in a flat NPSHr characteristic curve which helps to minimize the barrel and pump length.

Available Designs:

Single Suction & Double Suction First Stage



Sulzer Pumps


Available Designs:

Single Suction & Double Suction First Stage

Double Suction First Stage Design

These CEP pumps are intended for application 60Hz coal fired power plants.

Designed with a double suction, low NSS, first stage impeller. Thus resulting in a steeper NPSHr characteristic curve to comply with NSS limitation (< 11,000). This requirement is normally present in NAM specifications. This results in acceptable overall barrel and pump length.

SJD → vertical condensate pump

18DHC → series stage, nominal diameter of bowl [in]

Detail of Thrust Bearing in Pump – 50Hz Pumps

Note 1: Values given are calculated for full diameter impellers. If impellers are trimmed, the L10 rating life will be increased.


Sulzer Pumps

SJD (CEP) Vertical Condensate Extraction PumpsShaft Sealing – 50Hz Pumps

Shaft sealing by dual mechanical seal in back-to-back configuration.

Dual seals are used to avoid air inlet through the seal due to low suction pressure.

Burgmann or John Crane cartridge seals are available (seal housing compliant with API 682).

See below for piping diagram.
