ISW series horizontal centrifugal pump, is the ideal, new generation, high efficiency, enegy saved product, which is according to the performance parameter of the IS,IR type centrifugal pump and ISO standard, adopt excellent design of domestic hydraulic module.
Characteristic
- Compact structure, with motor,beautiful outline,take small place, about 30% reduce compare to common horizontal type. It can working in outdoor with IP54 outdoor motor.
- Stably operated,low noise,direct coupling, the impeller has balance performance with non-vibration, low noise, which is re-long the use life of the shaft bearing, and improve the working environment.
- Seal adopt good mechanism seal,dynamic and static loop are made of hard alloy, anti-grind,non-leakage, long used.
- Adopt advanced hydraulic module with highefficiencyand good performance.
- Particular structure.the pump bottom has a water discharge hole,and take pressure hole both in inletand outlet flange which is confirm good performance and maintenance.
- Level inlet,vertical outlet,that convenience to install the pipe.
Use
ISW series horizontal centrifugal pump, it is mainly used in water supply and liquid similar with water in physical and chemical quality, applicable to water supply and drain for factory and city, high building, boat, garden irrigation, firefight, long distance water supply, bathroom and other water circulation kit, the medium temperature is not exceed 85℃.
Working Condition
- The max working pressure (suction pressure +lift pressure) of pump system is not exceed 1.6Mpa, if higher than it, pls tell us ,we can make it with steel casing of liquid contact part and contact accessories.
- Transport water and liquid similar with water in physical and chemical quality,if the medium contains granule, pls tell us , so that we can installed grind proof mechanism seal.
- Circumambient temperature is not exceed 40℃, altitude is below 1 000 m, relative humidity is below 95%.
Model Meaning
Structure Introduce
This pump is formed by pump body, motor, bottom seal, the structure include pump body, impeller, pump cover, mechanism seal, and other accessories. It is single suck single stage horizontal centrifugal pump, most impeller has seal loop both face and back, and balance hole on back surface to balance the rotator. Pump and motor adopt direct coupling, so it is no need to verify bottom seat with JG anti-vibration.
- The pipeline should have bracket, do not put its weight on pump,to protect the pump.
- Pump and motor is one structure, no need to verify.
- Before installation, pls screw down the bottom bolt to avoid vibration when operation.
- Before installation, pls checked there is no hard object in pump, such as small stone, iron granule to avoid destroying the impeller and pump body.
- For convenient to repaired and safely operation, you’d better installed a adjust valve on both inlet and outlet pipeline and a pressure test instrument, so that pump operated in the lift and discharge range to protect it.
- If it is used on sucking situation, your should installed bottom valve, the inlet pipeline should have less curve, no leakage of both water and air.
- Reverse valve on outlet pipeline should installed at the out of gate valve.
- After be installed, handle the shaft, the impeller should has rub noise or locked, or, disassemble it and check it.
- It has two installed way, indirect and direct connect.
Started and Stopped
(1) Pre-start
- Handle motor vane to make sure the impeller rotate well with no rub.
- Open inlet valve ,open air drain valve to full fill with liquid,then closed the air drain valve.
- Handle pump to fill lubricant into mechanism seal.
- Start motor and make sure the rotate direction is right.
(2) Start and operation
- Completely open the inlet valve,closed valve on outlet pipeline.
- Open the power,when the rotational speed reach to the right speed,gradually open outlet pipeline valve and adjust to right working condition.
- Pay attention to the pressure meter,and make sure the seal and motor are working well. The normal leakage of the seal is below 3 drop/min, the motor working temperature is below 70℃. Or, pls check it in time.
(3) Stop
- Gradually closed the valve on outlet pipeline, cut off the power.
- Closed inlet valve.
- Drain out of all liquid in pump to avoid frozen to fracture if the temperature is below 0C.
- If no use for a long time, pls disassemble it, cleaned,packed, and saved.
