Vertical multi-stage centrifugal pump, also called CDLF vertical multi-stage centrifugal pump, is a non-self-priming vertical multi-stage centrifugal pump designed and manufactured by absorbing advanced domestic and foreign technologies. It uses a standard vertical motor and a quick-install mechanical seal, which is very convenient to replace. The flow-passing parts of the pump are made of stainless steel (304\316) and can be used in mildly corrosive media.

Vertical multistage centrifugal pump types:

Common vertical multistage centrifugal pumps include: light vertical multistage centrifugal pump, stainless steel vertical multistage centrifugal pump, vertical multistage pipeline centrifugal pump, DL vertical multistage centrifugal pump, VMP vertical multistage centrifugal pump, CDLF vertical multistage centrifugal pump, vertical multistage hot water centrifugal pump, etc.

Vertical multi-stage centrifugal pump price:

Unit price: 2400~2500 yuan/unit

Lanzhong Electromechanical has the ability to design and produce various forms of DC water pumps, and can customize the structural type, rated flow rate, installation method, etc. according to customer needs. We will quote and wholesale supply based on the design and production difficulty of the water pump as well as the order quantity. Large quantity and good price are welcome to buy!

Vertical multistage centrifugal pump model:

Vertical multistage centrifugal pumps are generally represented by GDL, and are matched with relevant data to represent different models of centrifugal pumps. Different models represent different performance parameters of these centrifugal pumps. The following is the naming convention for vertical multistage centrifugal pump models:

For example: 50 GDL -18-15×6: 50 represents the pump inlet and outlet diameter, GDL represents the vertical multi-stage centrifugal pump, 18 represents the design point flow, 15 represents the single-stage head, and 6 represents the number of pump stages.

Vertical multi-stage centrifugal pump medium:

1. Thin, clean, non-flammable and explosive medium that does not contain solid particles or fibers.

2. Such as mineral water, softened water, pure water, clear oil and other light chemical media.

3. The main material of the pump is stainless steel, which can be used to pump mildly corrosive media.

Working principle of vertical multi-stage centrifugal pump:

When the motor drives the impeller on the shaft to rotate at high speed, the liquid filled in the impeller is thrown from the center of the impeller along the flow path between the blades to the surroundings of the impeller under the action of centrifugal force. Because the liquid is affected by the blades, the pressure and speed increase at the same time. It passes through the flow path of the guide shell and is directed to the next-level impeller. This is the principle. It flows through the impeller and guide shell one after another, further increasing the pressure energy of the liquid. After each impeller is stacked step by step, a certain lift is obtained.

Vertical multistage centrifugal pump features:

1. The vertical type adopts excellent hydraulic model and advanced manufacturing technology to greatly improve the performance and service life of the pump.

2. Since the shaft seal uses mechanical seals made of cemented carbide and fluororubber, the stability of the pump operation and the temperature of the transported medium can be improved.

3. The flow-passing part of the pump is stamped and welded by stainless steel plates, making the pump suitable for mildly corrosive media.

4. The overall structure is compact, small in size, light in weight, low in noise, good in energy saving, and easy to maintain.

5. The water inlet and outlet of the pump are located on the same horizontal line as the pump base and can be directly used in the pipeline.

6. Using standard motor, users can easily equip the motor according to their needs.

7. Intelligent protectors can be equipped according to user needs to effectively protect the pump from dry running, phase loss, overload, etc.

Vertical multi-stage centrifugal pump structure:

Vertical multistage centrifugal pump is composed of four parts: stator, rotor, bearing and shaft seal. The stator part is composed of the suction section, the middle section, the discharge section and the guide vane group; the rotor part is composed of the pump shaft, impeller, bushing, impeller stop sleeve, etc.; the bearing is mainly composed of the bearing body, bearing and bearing gland; the shaft seal is mainly composed of the sealing box body, packing, water retaining ring, etc. on the water inlet section and the tail cover.

Vertical multi-stage centrifugal pump uses:

1. Water supply: water plant filtration and transportation, water plant district water delivery, main pipe pressurization, and high-rise building pressurization.

2. Industrial pressurization: process water system, cleaning system, high-pressure flushing system, fire protection system.

3. Industrial liquid transportation: cooling and air conditioning systems, boiler water supply and condensation systems, machine tool accessories, acidic and alkaline media transportation.

4. Water treatment: ultrafiltration system, reverse osmosis system, distillation system, separator and swimming pool water treatment system.

5. Irrigation: farmland irrigation, sprinkler irrigation, drip irrigation.
