Condensate pumps are electric centrifugal pumps used in industrial and household settings. Pumps condensate water from steam condensate pumps for boilers, HVAC systems, heat exchangers, and radiators that cannot be drained by gravity. It can be used in ship steam power plants. Power production units produce acidic condensate water with a pH of 3–4, therefore pump corrosion resistance is higher. Condensate pumps operate intermittently because condensate water is only discharged when it accumulates.
Kaiquan Pump Group manufactures condensate pumps for major power plants and offers complete condensate water treatment systems. Kaiquan Pump Group makes barrel-type KNL, LDTN, and N series condensate pumps.
Vertical barrel-type condensate pumps KNL and LDTN are appropriate for condensate water systems in power production units from 15MW to 1000MW. These items can also transport water-like fluids in chemical processes with limited NPSH or installation surfaces at an 80°C medium temperature. Kaiquan Pump Group also makes boiler and condensate water pumps for industrial use.
Barrel-type installation structure with a fully vacuum-designed outer barrel to meet low net positive suction head (NPSH) requirements.
Specially designed first-stage impellers for excellent cavitation resistance, with some models using inducer wheel structures and others using double-suction impellers.
Use of space guide vanes to reduce the pump’s radial dimensions while ensuring performance requirements and sufficient rigidity.
Convenient pump disassembly and maintenance due to the core-pulled structure in the lower part of the pump.
Use of high molecular composite material for guide bearings with lubricating water slots for thorough lubrication and cooling.
Balancing of axial forces through balancing holes and chambers, resulting in reduced axial forces compared to similar products without balancing holes, leading to increased reliability.
Incorporation of thrust bearings and the use of elastic couplings between the pump and the motor for convenient on-site installation and alignment.
Use of double-rolling bearing brackets in LDTN models and tilting-pad sliding bearing bodies in KNL models.
Adoption of self-lubricating systems and built-in oil coolers for sliding bearing bodies, ensuring uniform load distribution and low temperature rise during normal operation.
Option for mechanical seals or packing seals based on user requirements, with convenient disassembly and reliable operation for cartridge mechanical seals and minimal leakage.
Counterclockwise pump shaft rotation when viewed from the coupling end.
Placement of the pump inlet above or below the foundation based on customer requirements.
The N-type condensate pump is mainly used for conveying condensate water in thermal power plants, and can also be used in other applications with similar media properties to condensate water. The pump has good suction performance and is available in horizontal cantilever single-stage, two-stage, and single-stage with inducer wheel structural types. N-type condensate pump applications: Flow range: 8100m²/h, Head range: 38141m, Medium temperature: <80℃ (pumps 100N130 and 150N110 can handle liquids up to 120℃). Pumps 100N130 and 150N110 can be used as descaling pumps after injecting cooling water into the stuffing box and stuffing box cover.
