CDLF vertical stainless steel multi-stage centrifugal pump, lightweight multi-stage pump

1CDLF vertical stainless steel multi-stage centrifugal pump, lightweight multi-stage pumpProduct 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.

IICDLF vertical stainless steel multi-stage centrifugal pump, lightweight multi-stage pumpProduct Overview:

4、 CDL stainless steel stamping pump product usage:

The product is suitable for low viscosity, neutral, non explosive liquids that do not contain solid particles or fibers. The transported liquid must not have chemical corrosiveness to the pump material.

Boiler feedwater and condensate system

Agriculture, nurseries, golf course irrigation

● Food and beverage industry

Industrial cleaning system

Air conditioning and refrigeration coefficient

5CDLF vertical stainless steel multi-stage centrifugal pump, lightweight multi-stage pumpSmall import pressure:

If the pressure in the pump is lower than the vapor pressure of the conveyed liquid, cavitation may occur. To avoid cavitation, ensure that there is a small pressure on the inlet side of the pump and a large suction stroke H [m] can be calculated according to the following formula:

● H=pbX10.2-NPSH-Hf-Hv-Hs

● pb=atmospheric pressure [bar]

(Atmospheric pressure can be set to 1 bar)

In a closed system, pb is the system pressure [bar]

NPSH=Net Positive Suction Head [m]

(Can be read from the possible high flow output of the pump on the NPSH curve)

Hf=inlet pipeline loss [m]

Hv=vapor pressure [m]

Hs=safety margin=0.5m head less

If the calculated value of H is positive, the pump can operate with a large suction range of H.

If the calculated value of H is negative, there must be a small water head with an inlet pressure of H.

6、 Multi stage stainless steel stamping pump backflow 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 the liquid being transported) in order to start.

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!
