ALW Series Horizontal Pipeline Single-stage Direct Connected
Centrifugal Pump
Overview
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 IS02858
standard . They are a new generation of highly effective and
energy-saving horizontal pumps
Features
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
sound performance
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.
Usage
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°C.
2 . ALWR horizontal hot water circulating pumps are applicable to
pressurized circulation of hot water for boilers used in the fields
of energy sources . metallurgy , woodworking . chemical ,
textile,papermaking , restaurants , bathrooms , hotels and etc ,
and heating circulation in houses . Service temperature below
120°C.
3 . ALWH horizontal chemical centrifugal pumps are applicable to
handling corrosive liquids in the industries of petroleum chemical
, metallurgy , electric power , papermaking , foodstuff
.pharmaceutical and synthetic fiber etc . Service
temperature-20~105°C.
4 . ALWY horizontal explosion-proof oil pumps are applicable to
handling inflammable and explosive liquids in the industries of
petroleum , textile , chemical and machinery etc . The temperature
of medium to be delivered not exceeding 120°C.
5 . ALWHY stainless steel horizontal explosion-proof chemical
centrifugal pumps are applicable to handling inflammable and
explosive chemical liquids.
6 . ALWD . ALWRD ALWHD . ALWYD and ALWHYD horizontallow speed
centrifugal pumps are applicable to conditions that are very strict
with environmental noise , especially applicable to cooling water ,
circulation of cooling water , and end pressurization of
air-conditioning system.
