Vertical multi-stage centrifugal pump is a high efficiency and energy saving excellent hydraulic model, so it has high efficiency, wide range of performance advantages, and better meet the user's requirements. In addition, the pump in the structure of the vertical, sub-form, and safe operation, smooth, long life, small footprint, safe and easy maintenance. Vertical multi-stage centrifugal pump using the international recommended efficient energy-saving products, hydraulic model for the vertical multi-level multi-segment structure, the screw into the water section, the middle section of the water section together. Each level of the pump is equipped with an impeller, a water guide. The axial force is solved by the hydraulic balance method, and the residual axial force is borne by the ball bearing and lubricated with grease. Shaft seal with soft packing or mechanical seal. Germany Thomas imports of vertical multi-stage centrifugal pump is mainly for the absorption of diluted, clean, non-corrosive, non-explosive water and physical and chemical properties similar to the water without solid particles or fiber liquid.

The scope of application

Widely used in high-rise building fire, water supply and air conditioning unit cycle, cooling water delivery.

Features

1, advanced hydraulic model: high efficiency, wide range of performance.

2, the structure is novel, reliable operation: the elimination of the balance drum, the axial force of the use of hydraulic balance, completely solve the balance drum easy to rust, easy to kill, easy to wear problems, to ensure a more reliable operation.

3, less running, maintenance costs: the use of high-quality mechanical seals, wear-resistant, no leakage, long life, low failure rate, with less running and maintenance costs.

4, smooth operation, low noise: the use of low-speed motor, the pump running smoothly, the noise is lower.

5, vertical structure, small footprint.
