Horizontal Self Balancing Multistage Pump(without balancing disc)


The self balancing multi-stage pump adopts advanced hydraulic models and independently develops high-efficiency and energy-saving products; Due to the absence of wear and axial pulsation of the balance disk in the rotor of the self balancing symmetrical multi-stage pump, the alignment between the impeller and guide vanes is always in the optimal state, and the efficiency will not significantly decrease with the wear of the balance disk and the forward movement of rotor components like in ordinary multi-stage pump structures; And there is no leakage of balancing water, reducing volume loss, improving the overall operating efficiency of the pump, reducing shaft power, and averaging 2% -3% higher efficiency than ordinary multi-stage pumps.

Description

The horizontal multi-stage self balancing pump is of New technology and new structure that rotor components with symmetric impellers, the product offsets the axial thrust generated during operation of forward and backward sets of impellers. In this way, the balancing disc device with small clearance and high pressure drop, which is easily flushed, worn and fails is not needed to keep axial force balancing, breaking the traditional structure of multi-stage pump. Unique throttling and pressure relieving device, odd-level balancing device, playing a supporting role.

Competitive Advantage

● High reliability, High cavitation resistance, Strong reliability of mechanical seal, Low maintenance rate, Strong applicability.

● High efficiency and energy conservation: Advanced hydraulic model and independently developed high-efficiency energy-saving, 2%-3% higher than ordinary multi-stage pump in efficiency.

● Easy maintenance: Without dismantling the pump body and inlet/outlet pipelines. There are no wearing parts such as balancing disc in the pump, thus saving time for overhauling and inspection.

● Low maintenance rate: Precise casting is adopted, thus reducing wearing components and times of maintenance and disassembly, extending service life, avoiding problems caused by too many times of disassembling, and lowering the maintenance cost.
