Vertical multistage barrel condensate pump designed for condensate recovery and high-head liquid transfer in industrial plants. The LDTN series is a vertical, multi-stage, barrel-type centrifugal pump with adjustable suction and discharge orientation (standard 180°; 90° and other arrangements available). It uses closed radial impellers and is intended for condensate in thermal and nuclear power plant condensers and for transporting clean or slightly contaminated liquids with physical and chemical properties similar to water (maximum fluid temperature 180°C).
Key features
- Vertical multistage barrel construction with suction and discharge on the discharge seat; suction/discharge ports can be rotated to suit installation (typ. 180° or 90°)
- Closed, single-suction radial impellers; first stage typically suction type
- Designed for condensate and water-like fluids (neutral or mildly corrosive)
- Wide hydraulic range: inlet diameters 80–400 mm; flow 7–702 m3/h; head 35–232 m; motor power 3–630 kW
- Standard voltages: 380 V and up to 6000 V
- Max fluid temperature up to 180°C
Mechanical and installation details
- Radially split, multi-stage pump with single-stage casing; shell supports inlet pressure only
- Axial loads carried by thrust ball bearings; where large axial thrust exists, a balance drum is used to equalize forces
- Radial bearings in the bearing housing are oil-lubricated via a constant-level oil cup; an inlet-end hydrodynamic sleeve bearing is provided where required
- Shaft sealing options: single mechanical seal, double mechanical seal, or cartridge/series mechanical seals
- Motor drives pump through a flexible coupling; standard motor mounting V1
- Standard rotation (viewed from driver end) is counterclockwise; model 150LDTN-100 is clockwise
- Pump length and installation depth configured to meet NPSH/cavitation requirements
Model coding (typical)
- Example: 200LDTN-125– indicates suction diameter 200 mm; L = vertical; D = multistage; T = barrel type; N = condensate pump; 125 = discharge diameter (mm). Stage count and other options are appended as required.
Typical applications
- Condensate extraction in thermal and nuclear power plants
- Refinery and petrochemical condensate and cooling circuits
- Pipeline pressurization and feedwater systems
- Offshore platforms and other installations with limited footprint or NPSH constraints
Options and customization
- Multiple suction/discharge orientations and flange arrangements
- Seal and bearing arrangements tailored to duty and liquid characteristics
- Materials, coatings and hydraulic trims selectable to match fluid chemistry and temperature within the stated limits
