The KQL,and KQW series Fourth-generation Single-stage Single-suction Centrifugal Pumps, are well designed by our company using the best hydraulic model and according to different working conditions of different users. This series features compact and reasonable structure, stable and reliable operation; a mechanical seal of a special structure is adopted for this series to improve operating environment and extend the service life; it is also characterized by high efficiency, low operating costs, less administrative costs; small footprint, less construction investment, and favorable market response.
Circulating water for central heating systems; chilled water and cooling water circulation for air conditioning systems
Water treatment, sanitary water; indoor domestic water supply, domestic hot water systemsWater supply, water for irrigation system; water for flushing system
1.In this series, the pump and motor are directly connected in such a manner that the motor shaft and pump shaft are completely concentric to bring down vibration and noise; and bearings of a special structure and short cantilevered impellers contribute to stable and reliable operation
2.A kind of specially structured mechanical seal with a forced circulation but without limit on direction of rotation is adopted to improve operating environment and prolong service life.
3.An advanced design of pump chamber and impeller give superior hydraulic properties to the pump, ensuring efficiency and energy conservation, low operating costs, less operating and administrative expenses reduced by50%-70%
4.The unique mounting structure greatly reduces the footprint of pump, as well as construction investment by40%-60%
5.The stainless steel shaft, which never gets rusty, ensures easy disassembly of mating parts, mechanical seal and sylphon seal are reliable, service-free, and easy to maintain.
