W Marine Single Stage Vortex Pump

Overview

W type is a single level cantilevered vortex pump. Suitable for conveying temperature from -20℃~+80℃, viscosity is not greater than 5°E, without solid particles in a liquid. Flow components of the material is divided into HT200, Cr18Ni12Mo2Ti three and aluminum cast iron. (Respectively H, J and M code of materials express). Seal forms a soft packing seal and mechanical seal. W type vortex pump by the pump to the motor rotation direction: the direction for counterclockwise rotation.

Advantages and Disadvantages of Vortex Pumps

Advantages of Vortex Pumps

1. Vortex pumps are widely used on ships for sea and canal transportation. The small size and light weight of the vortex pump are extremely advantageous.

2. The vortex pump has the self-priming ability, and can also realize the self-priming function with the help of a simple device.

3. The rate of change of the flow head curve of the vortex pump is relatively large, so the vortex pump is not sensitive to pressure fluctuations in the system.

4. Some vortex pumps can realize vapor-liquid mixed transportation. This is of great significance for pumping volatile liquids containing gas and high-temperature liquids with high vaporization pressure.

5. The temperature of the conveying medium of the vortex pump should be controlled within a certain range and cannot exceed 60 °C.

Disadvantages of Vortex Pumps

1. Due to the small size and simple structure of the vortex pump, this also causes the efficiency of the vortex pump to be low. The efficiency of the vortex pump is generally between 20-40%.

2. The cavitation performance of the vortex pump is poor.

3. The vortex pump cannot be used to pump viscous medium. During the working process of the vortex pump, the head and efficiency of the vortex pump will decrease sharply with the increase of the viscosity of the liquid.
