Low Or High Pressure,Single Stage Horizontal Centrifugal Pump For
ALW, ALWR, ALWH, ALWY, ALWHY, ALWD, ALWRD, ALWHD,ALWYD and ALWHYD
series horizontal centrifugal pumps are optimally designed with
domestic advanced hydraulic models, which are based upon the
performance parameters of IS and IR centrifugal pumps, and ISO2858
standard. They are a new generation of highly effective and
energy-saving horizontal pumps.
1. ALW horizontal centrifugal pumps are used to handle clean water
and liquids similar to water in physical and chemical properties.
They are applicable to industrial and city water supply and
drainage, pressurized water supply in high-rise constructions,
ships, garden irrigation, fire-fighting pressurization, distant
transportation, heating, ventilating, refrigeration circulation,
and bathrooms for cyclic pressurization of cold and hot water, and
other equipments. Temperature of service medium not exceeding 85℃.
1. Compact structure. Horizontal structure, integration of motor
and pump, appealing appearance and less occupation space. Compared
with ordinary horizontal pumps, it saves occupation space by 30%.
If IP54 outdoor motor is used, it can be used outdoors with no need
of a pump room.
2. Smooth operation, little noise and high concentricity of
components. Close coupled motor and pump to have simplified
intermediate structure and increased running stability. Impeller is
provided with excellent dynamic and static balance to obtain no
vibration and low noise in operation, which has lengthened the
service life of bearings and improved the service conditions.
3. Use of quality mechanical seal for shaft seal, rotating and
stationary seal rings made of hard alloy to effect abrasion
resistance, leak tightness and long service life.
4. Use of advanced hydraulic model to feature high efficiency and
5. Distinctive structure. Pump body fitted with water drain hole at
the underside, inlet and outlet flanges fitted with pressure
tapping, thus to ensure normal operation and maintenance.
6. This series of pumps have horizontal inlets and vertically
upward outlets for the convenience of pipeline arrangement.
1. The maximum working pressure of pump system is 1.6MPa,namely
pump suction pressure + pump delivery head ≤1.6Mpa.(To acquire
working pressure of pump system greater than 1.6MPa should be
specified separately when placing an order for our convenience to
use cast steel for wetted parts and connection parts in
2. The medium to be handled shall be clean water or other liquids
similar to water in physical and chemical properties. (To handle
medium carrying small particles, please specify when placing an
order for our convenience to use wear resistant mechanical seal).
3. Ambient temperature not exceeding 40℃, height above sea level
not exceeding 1,000m, and relative humidity not exceeding 95%.
