1. Steady running: the pump bearings share exactly the same axle and the impeller has excellent static and dynamic equilibrium. Therefore, the pump can work stably, no vibration.
2. No water leakage: hard alloy seal with different material ensures that different liquids can be delivered without leakage.
3. low noise: supported by two low noise bearings, the pump can run stably with almost no noise except a slight sound of motor.
4. Low failure rate: simple and reasonable structure, the key parts are made of material with international first-class quality. The whole machine is trouble free. Its working efficiency is greatly improved.
5. easy maintenance: it is easy to replace seal and bearing.
6. Taking little space: the outlet has three optional directions: to left, to right and upward, which makes it convenient to lay out and install pipelines, saving space.
1. The ISW series horizontal clear water pump, used in delivery of clear water and other liquids with similar physical and chemical properties as water. It can be applied for industrial and city supply and drainage, pressurized water supply for high-rise buildings, garden sprinkler irrigation, pressurizing water for fire fighting, long distance water delivery, HVAC refrigeration cycle, bathroom water supply and other hot and cold water circulation and pressurization. The temperature T<80℃.
2. ISWR horizontal hot water pump is widely used in metallurgy, chemical industry, textile, paper making, hotel and other situations that needs to pressurize and recycle and deliver high temperature water from boiler. It is also suitable for water circulation in heating system for warmth in the city. ISWR type operating temperature≤120℃.
3. ISWH horizontal chemical industry pump delivers corrosive liquids as sticky as water but contains no solid particles. It can be applied to petroleum oil industry, chemical industry, metallurgy, power station, paper making plant, food and pharmaceutical and synthetic fiber business, etc. Operating temperature –20℃~+120℃.
4. ISWB horizontal pipeline oil pump is used in delivery of petrol, paraffin, diesel and other petroleum products or inflammable, explosive liquids; the temperature of the liquids being pumped shall be –20℃~+120℃.
5. ISWD horizontal low speed pump suits for situations where low noise is strictly required. Working temperature T≤120℃.
