Manufacturing Technique



High precision castings with standard dimensions, smooth flow channels, and low hydraulic losses.

The exquisite casting and processing technology ensures a high degree of alignment between the flow channel and the design flow line, and the pump efficiency can be improved by 3% -5%.


Each pump undergoes a static pressure test, with a pressure of 1.2 times the design applied and maintain
for 30 minutes, ensure that the pump has no leaks, sweating, or other defects and meets pressure requirements.

SPEED DYNAMIC BALANCE


The original speed dynamic balance,
with an accuracy level of G2.5, achieves
the stability of on-site operation of the
water pump.





Wide Efficient Zone: Effectively ensuring that the water pump can operate within an efficient and safe working range even when the water supply flow changes over a wide range, thereby reducing the risk of inefficient operation and cavitation of the water pump.
Our double suction pump is equipped with international top brands of sealing&bearings to improve the safe and stable operation of the equipment




Stainless steel impeller precision casting, precise size, high surface smoothness makes 2% higher
pump efficiency.
Strong corrosion resistance, able to resist slight cavitation caused by
short-term high flow operation of
water pumps.
