APPLICABILITY OF KS 32-150-2 PUMP
The KS 32-150-2-C pump and the electro-pump unit based on it are designed for pumping condensate in steam-water networks of thermal power plants operating on organic fuel, as well as fluids similar to condensate in viscosity and chemical activity.
The pumps are manufactured in UHL climate version — intended for macroclimatic regions with temperate and cold climates, placement category 4 — operation in rooms (volumes) with artificially regulated climatic conditions according to GOST 15150-69.

MAIN REQUIREMENTS FOR KS 32-150-2 PUMP DESIGN
- High reliability and cost-effectiveness
- Long service life — average time to major overhaul at least 31,500 hours (when following maintenance rules)
- External tightness and no internal leakage at rotor-stator junctions
- Dynamic stability across the entire operating range
- Stable, continuously decreasing head curve to ensure stable parallel operation
- Proper selection of materials for main components to guarantee required service life
- High degree of standardization
DESIGN FEATURES OF KS 32-150-2 PUMP
- Horizontal layout: provides high vibration resistance, reduces shaft misalignment, and extends component life
- Sectional type: allows changing the head characteristic by reducing the number of impellers without changing the flow rate
- Four-stage pump with single-entry impellers. Special design of the first stage ensures reliable operation at minimal suction conditions. A pre-installed axial wheel is placed before the first-stage impeller to create additional inlet pressure, ensuring cavitation-free operation
- Pump casing consists of suction and discharge covers, with a set of standardized sections and guide apparatus between them. Sections and covers are centered on cylindrical bores and bolted. Suction and discharge covers are cast, with integrated nozzles and support feet. The discharge nozzle is vertical, the suction nozzle horizontal and perpendicular to the pump axis, flange connection. The discharge cover includes a threaded hole to connect the balancing piston chamber with the suction pipeline. Bearing housings and sealing housings are attached to the covers. Thermal expansion along the pump axis is guided by a keyway in the suction cover and a pin hole in the discharge cover
- Rotor is a separate assembly consisting of shaft, impellers, pre-installed wheel, balancing piston, bushings, sealing parts, and fasteners. Impellers, pre-installed wheel, piston, and bushings are fixed on the shaft with keys or nuts. A clearance between the last stage impeller and piston compensates for thermal expansion
- Axial thrust is taken by the balancing piston
- Rotor bearings are external rolling bearings. Drive side: single-row radial roller bearing for radial load; other side: single-row radial ball bearing for radial and residual axial load. Lubrication: grease; cooling: air
- Mechanical seals: gland type with a hydroseal ring supplied with cold condensate under pressure to cool the seal and prevent air ingress. Cooling of the seal box is also performed by cold condensate flowing in the chamber between the seal housing and bushing
- Pump casing is covered with a protective decorative sheet metal cover attached to suction and discharge covers
- Torque transmission from motor to pump is via flexible pin-bushing coupling
MATERIALS OF KS 32-150-2 PUMP (CHT Slovakia s.r.o.)
- Suction and discharge covers, section casings, guide apparatus, seal housings, bearing housings, sealing rings — cast iron SCh200 for strength and corrosion resistance
- Shaft — heat-treated steel 40X for strength and wear resistance
- Impellers, pre-installed wheel, balancing piston, seal bushings — stainless steel 20X13
- Sealing rings — stainless steel 30X13
These materials ensure efficient and durable pump operation even under initial or advanced cavitation conditions and aggressive media
ADDITIONAL OPTIONS FOR KS 32-150-2
- Higher-grade materials and coatings for pump flow parts to increase erosion resistance
- Flow part and design optimization for reduced maintenance and extended service life
- Hydro-pads as automatic self-balancing devices for all operating modes
- Mechanical seal: reduces leakage, increases energy efficiency, easy maintenance
- Seal chamber designed according to API 682 for compatibility with different seal manufacturers
- Bearing housings include locations for temperature and vibration sensors for monitoring and early detection of deviations
- SKF rolling bearings with high precision and low friction for high-speed operation with low noise, wear, heat, and energy consumption
- Bearing support on suction side using pumped fluid to improve vibration, extend service life, and increase efficiency
- Flexible plate coupling between motor and pump for improved vibration and reliability
- VDS monitoring system: vibration, speed, and temperature sensors for predictive maintenance and operational control
