Based upon the performance parameters of IS and IR centrifugal pumps，and the standard of IS02858，ALW series horizontal centrifugal pumps are a new generation of high—efficiency and energy-saving products designed with the advanced hydraulic model in China．
1、ALW horizontal type centrifugal clear water pump is used to transport clear water and other liquid has chemical and physical property similar with the clear water. It is applicable to water supply and drainage for industry and city pressure increasing water supply for high building ,garden irrigation, pressure increasing for fire fighting, long distance transportation, heating and cooling circulation, cold and warm water circulation pressure increasing and matching equipment, the using temperature is T ≤ 80 ℃.
2、 ALWR horizontal type hot water pump can be broadly used in metallurgy, chemistry, waving, papermaking, boiler hot water pressure increasing circulation transportation for hotels and warmth supply system for cities. The using temperature for ALWR type is T ≤ 120 ℃ .
3、ALWH horizontal type chemical pump is used to transport the liquid , which is corrosive, no containing solid grain, has the viscidity similar with water. It is applicable to petroleum, chemistry, metallurgy, electricity power, papermaking, food, pharmacy and synthetic fiber department, .The using temperature for ALWH type is T ≤ 120 ℃.
4、ALWY horizontal type pipe oil pump is used to transport gasoline, kerosene, diesel oil products and other flammable explosive liquid , the temperature of the medium transported is - 20 ℃ ～ 120 ℃ .
5、 ALWHY type stainless steel anti-explosion chemical centrifugal pump is applicable to transport the flammability chemical liquid.
6、ALWD is horizontal low speed centrifugal pump is applicable to the environment require very low noise and circulation for air-conditioner,.
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 seqarately when placing an order for our convenience to use cast steel for wetted pads and connection parts in production)．
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％．
1．Compact horizontal structure and integrated body of motor and pump to feature smart profile，lessened occupation area by 30％compared with the ordinary horizontal pumps．If provided with I P54 outdoor motors，this series of pumps can be used outdoors，with no need of a pump room．
2．Smooth operation，low noise and high concentricity of components。Motor and pump are directly connected to simplify the intermediate structure and to increase operating smoothness．The impeller IS given superior dynamic and static balance to effect Iittle vibration and low noise in operation，to lengthen the service life of bearings and to better the service conditions．
3．Quality mechanical seal for shaft seal，both rotating and stationary seal rings made of hard alloy to feature wear resistance．no leakage and long service life．
4．Use of advanced hydraulic model to feature high efficiency and outstanding performance，etc．
5．Distinctive structure，with water drain hole fitted at the lower part of pump body，and pressure holes at the inlet and outlet flanges，thus to ensure the normal operation and maintenance of pump．
6．This series of horizontal pumps are fitted with horizontal inlet and vertical upward outlets for the convenience of pipeline arrangement．
