Fit-for-purpose condensate extraction pump
LTDN 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.
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
The LTDN 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
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
