CDL/CDLF is a non-self-priming multi-stage centrifugal pump equipped with a standard motor. The motor shaft is directly connected to the pump shaft through the pump head with a coupling. The tie rod bolts fix the pressure cylinder and flow-passing components to the pump head and the water inlet and outlet section. The pump inlet and outlet are on the same straight line at the bottom of the pump; this pump can be equipped with an intelligent protector as needed to effectively protect the pump from dry running, phase loss, overload, etc.

CDL/CDLF type light vertical multi-stage pump Working principle

Multi-stage centrifugal pumps rely on the rotation of the impeller to obtain centrifugal force and thereby remove the material. When the gas density reaches the working range of the mechanical vacuum pump, it is pumped out, thereby gradually obtaining a high vacuum.

The multi-stage pump body is filled with an appropriate amount of water as the working fluid. When the impeller rotates clockwise, the water is thrown around by the impeller. Due to the centrifugal force, the water forms a closed ring of approximately equal thickness determined by the shape of the pump chamber. The inner surface of the lower part of the water ring is just tangent to the impeller hub, and the upper inner surface of the water ring is just in contact with the top of the blade (actually the blade has a certain insertion depth in the water ring). At this time, a crescent-shaped space is formed between the impeller hub and the water ring, and this space is divided by the impeller into several small cavities equal to the number of blades.

If the lower part of the impeller is 0° as the starting point, then the volume of the small cavity changes from small to large when the impeller rotates 180° before, and is connected to the suction port on the end face. At this time, the gas is sucked in. When the suction ends, the small cavity Then it is isolated from the suction port; when the impeller continues to rotate, the small cavity changes from large to small, causing the gas to be compressed; when the small cavity is connected to the exhaust port, the gas is discharged out of the pump.

CDL/CDLF Characteristics of vertical multi-stage pumps

The reason why vertical multi-stage pumps sell well in the market and win the favor of more consumers is mainly because the products have outstanding features and functions, such as:

1. The product is small in size, so it occupies a small area, and is more convenient to transport, disassemble and install.

2. The professional design, compact structure and beautiful appearance are deeply loved by the market.

3. Horizontal suction and discharge port design and simplified pipeline connections greatly improve service performance.

4. Different suction inlets and discharge outlets are installed at different angles to meet the needs of different situations and greatly improve work efficiency.

5. Without changing the installation area, the lift of the vertical multi-stage pump can be increased or decreased according to needs, and the number of pump stages and the outer diameter of the impeller can be cut, meeting the needs of different actual situations.

5. The use of the motor outer protective cover effectively saves the use of the pump room and reduces more construction costs.

6. The smaller winding of the pump rotor allows the pump body to operate with lower noise, smaller vibration, and smoother operation, improving work efficiency and extending its service life.

These outstanding features and performances have enabled the products to win high recognition from consumers. Product supply exceeds demand. Fierce competition has given birth to more brands and different types of products, promoting the healthy and rapid development of the industry.
