APPLICATION OF КSV 200-130 CONDENSATE PUMP
The condensate pump belongs to a special group of power pumps, operating under deep vacuum and minimal geometric suction conditions, and is designed to supply condensate from exhausted steam of stationary steam turbines, heating steam from heat exchangers at TPPs, NPPs, as well as clean water with temperatures up to 125 °C in heat and water supply systems, metallurgy.

The КсВ 200-130 condensate pump is driven by an asynchronous motor with a squirrel-cage rotor, 110 kW. The overall system efficiency (η) is 68%.
MAIN REQUIREMENTS FOR КSV 200-130 DESIGN
- High reliability and efficiency;
- External tightness and no internal leakage at rotor and stator joints;
- Long service life — mean time to overhaul at least 30,000 hours (with proper maintenance);
- Dynamic stability over the entire operating range;
- Stable, continuously decreasing head characteristic for stable operation when connected in parallel;
- Ease of assembly, disassembly, maintenance, and high repairability.
DESIGN FEATURES OF КSV 200-130
- Vertical design for maximum suction and favorable cavitation conditions;
- Two-body construction allows assembly/disassembly without disconnecting pipelines; one external sealing joint;
- First stage special design — screw-centrifugal stage with double-entry impeller and two pre-impellers;
- Outer casing welded, consisting of suction and discharge parts; support feet and suction/discharge nozzles welded;
- Inner casing is a separate assembly including rotor, mechanical seal, unloading unit, upper/lower bearing supports, covers, guide apparatus, supply casing, lantern;
- Upper thrust-radial bearing (double angular contact ball bearing) fixes rotor position and absorbs radial and residual axial forces. Lubrication — grease;
- Lower sliding bearing lubricated by pumped condensate, takes only radial loads, located in interstage seal;
- Rotor axial load relieved by slit seal on the main disc of the second-stage impeller; chamber before mechanical seal connects to suction cavity via balancing pipeline;
- Mechanical seal — gland type with sealing ring; cooled condensate under pressure supplied to prevent air ingress.
MATERIALS (CHT Slovakia s.r.o.)
- Outer casing: carbon steel;
- Main parts (covers, sections, guide apparatus, sealing rings, supply casing, upper bearing housing, seal housing): cast iron СЧ200 per DSTU 8833;
- Shaft: heat-treated steel 40X;
- Pre-impellers and impellers: stainless steel 20X13.
ADDITIONAL SUPPLY OPTIONS
- Mechanical seal — reduces volumetric leakage, increases energy efficiency, easy maintenance;
- Materials of main parts — alloy/stainless steel for flow parts, carbon steel for sections/covers/bearing housing to increase service life;
- Flow part — optimized blade and channel count for vibration and efficiency;
- Lower bearing — improved sliding bearing materials for lower friction, higher wear resistance, longer service life;
- Balancing disc (hydropad) — automatic axial load relief;
- Hydrocyclone — cleans liquid supplied to lower bearing, increasing service life;
- VDS monitoring system — vibration, speed, and temperature sensors for predictive maintenance.
