CDLF vertical stainless steel multi-stage pump lightweight centrifugal pump

Stainless steel multi-stage centrifugal pump, CDLF multi-stage water pump, stainless steel multi-stage pump price, 50CDLF16-50

1Product Overview:
The CDL/CDLF stainless steel multi-stage centrifugal pump is designed based on the advantages of ISG centrifugal pumps and GDL vertical multi-stage centrifugal pumps. The jacket is made of high-quality stainless steel, and the shaft seal is made of wear-resistant mechanical seal, with no leakage and long service life. By using hydraulic balance to solve axial force, it operates smoothly, has low noise, occupies a small area, and is easy to decorate. This series of lightweight multi-stage stainless steel centrifugal pumps is a new pump type that can meet the requirements of tower free water supplyIntegrated intelligent water supply with box pump、Non negative pressure water supply equipmentThe water supply, drainage, and fire-fighting facilities required for high-rise buildings, deep mines, and other industries are ideal pump types for transporting cold and hot water or general media with physical and chemical properties similar to water.

IIICDLF vertical stainless steel multi-stage pump lightweight centrifugal pumpBackflow system and open system:

Before starting, carefully read the signs on the pressure resistant cylinder of the pump.

The pump must be filled with water(Or transported liquid)Only then can it be started.

Fill the pump with water in the backflow system;

Close the pump outlet valve, open the exhaust valve on the pump head, slowly open the inlet valve until stable water flows out of the exhaust valve, and then tighten the exhaust valve. *Open the check valve on the suction line.

Fill the pump with water when the liquid level is lower than the pump in an open system.

Attention: A check valve must be installed on the suction line.

Close the pump outlet valve, open the exhaust valve on the pump head, inject the liquid into the pump through the exhaust valve hole until the pump and suction pipeline are filled with water, and then tighten the "air valve" again.

Do not start the pump until it is filled with liquid and emptied of gas!

Pay attention to the direction of the exhaust valve vent, and be careful to ensure that the overflowing water does not harm people or the pump and other components. In the heat

Be especially careful in water applications to avoid the risk of burns!

The major difference between multi-stage pumps and single-stage pumps is that multi-stage pumps have multiple impellers. The reason why pumps can transport liquids is that the centrifugal force generated by the impellers during high-speed rotation creates a pressure difference between the upper and lower parts of the impellers. Positive pressure is generated above the impellers, and negative pressure is generated at the bottom of the impellers. Therefore, the negative pressure generated by the pump during operation can suck water into the pump body and cause it to be thrown out through the impeller channel by centrifugal force to form positive pressure. Due to the limitation of energy efficiency, single-stage pumps can only achieve a large head of about 150. If they are further enlarged, not only will the size of the pump body, impeller and its components need to be increased, but also the motor power will need to be increased. Therefore, the land area and price will correspondingly increase. Therefore, the initial solution The solution is to use several single-stage pumps in series to solve the problem of high head transportation, However, with the development of the water pump industry, this solution that occupies space, wastes space, and constantly increases costs has been historically eliminated. Based on the above reasons, multi-stage pumps have been developed and have received high praise from users. As multi-stage pumps have multiple impellers working simultaneously, the pressure of multi-stage pumps increases step by step from each impeller, which means that each impeller is equivalent to a single-stage pump, and the pressure, that is, its head, is also the sum of the single-stage heads of each impeller. Therefore, multi-stage pumps are more efficient and energy-saving in use. With the same power, the output pressure of multi-stage pumps is much higher than that of single-stage pumps. The head of multi-stage pumps can now reach hundreds or even kilometers.
