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.
