Advantages

· Horizontal split pump casing

Horizontal split type multi-stage pump, the pump casing is horizontally split along the axis line, and the inlet and outlet pipes are cast in the lower half of the pump body.

· Single-inlet structure type

Adopt the structure of a single inlet.

·  Impeller design

Adopt the design method of closed impeller back-to-back distributed on the axis line.

·  Optimized internal runner structure

The optimized design of the inner flow channel shows that the performance curve of the pump is flat, the range of high efficiency is wide, the flow stability is good under the non-designed flow rate, and the pressure fluctuation is small.

·  Compact mid-open surface

The optimized design of high-strength bolts densely packed between the pump body and pump cover can ensure that the pump runs smoothly under high pressure. The opening surface is specially glued to ensure no leakage.

·  Reliable sealing

Packing Seal, traditional two-part mechanical seal and container mechanical seal can be selected according to the characteristics of the medium.

The clean water medium is designed as a self-washing structure, and the sewage medium can only be used as an external structure.

·  Washing structure

The clean water medium is designed as a self-washing structure, and the sewage medium can only be used as an external structure.
