What are the advantages of stainless steel vertical centrifugal pump-high pressure water pump?
The impeller, guide vane and guide shell are made of stainless steel plate stamped, drawn and welded, are sealed with hard alloy mechanical seal and guide bearing.
The vertical stainless steel centrifugal pump has the characteristics of small size, light weight, high efficiency, energy saving, stable operation, long service life, vertical installation, light weight and beautiful appearance. It is an ideal water
product.

Product Usage
Vertical stainless steel centrifugal pumps are especially suitable for boiler water supply, and can also be widely used in pressure vessel water supply, hot water circulation, high-rise building water supply, farmland irrigation, fire pressurization, hydraulic flushing, food, brewing, medicine, chemical industry, aquaculture, environmental protection Protection, chemical industry, machine tools and other industries as water supply and drainage power equipment.
Conditions of Use
1. Used to transport clear water or liquids with physical and chemical properties similar to clear water;
2. There should be no solid particles, fibers, strong corrosion and explosion hazard in the conveying liquid;
3. The liquid temperature shall not exceed 120°C;
4. The working pressure shall not exceed 2.5MPa;
5. The power supply is three-phase 380V, 50 Hz. The voltage fluctuation is within ±5%;
6. The ambient temperature should be lower than 40°C, and the relative humidity should be lower than 95%.
Maintenance
Maintenance during operation of vertical stainless steel centrifugal pump.
1. The water inlet pipe must be highly sealed without water or air leakage.
2. It is forbidden to run multi-stage centrifugal pumps under cavitation conditions for a long time.
3. When the motor is over-current, it is forbidden to run the multi-stage centrifugal pump for a long time under the condition of large flow.
4. Regularly check the current value of the motor during the operation of the multistage centrifugal pump, and try to make the pump operate within the design working condition range.
5. Multi-stage centrifugal pumps should be supervised by special personnel during operation to avoid accidents.
6. The bearings of multistage centrifugal pumps should be refueled every 500 hours.
7. The pump must be stopped for inspection, and the wearing parts and bearings must be replaced. The maintenance cycle of the unit is generally one year.
Maintenance of mechanical seal
1. The lubricating fluid of the mechanical seal should be clean and free of solid particles.
2. Dry grinding of mechanical seals is strictly prohibited.
3. Before starting, the pump should be rotated several times to prevent the mechanical seal from being broken and damaged due to sudden start.
