Rotor is in accordance with gb9239 standard g6.3 standard, dynamic balance test is conducted to ensure that each pump runs smoothly.
Pump housing:
With the help of wilo professional design software, the precise design of intake shape and corresponding blade geometry shape leads to higher hydraulic efficiency and lower NPSHr value.
Through the finite element stress analysis, the bearing boundary is checked and the service life is prolonged.
High lift pump adopts double volute design, which can balance radial force effectively, improve the stability of pump operation and the service life of pump bearing.
Flange:
According to GB standard, it can also be customized according to ANSI, JIS and other standards.
Wear ring:
Replaceable wear ring, protect pump body from wear. Through precise calculation and design of wear-resistant ring, the pump is always running efficiently and the operation cost is reduced.
Shaft:
The overall dimension and stiffness of the shaft are calculated by rigorous stress to adapt to complex operating conditions.
The material of the shaft is 20cr13, which adopts fine grinding process and ultrasonic nondestructive testing.
Small bearing span and thickened shaft design, good rigidity and small deflection, effectively reduce vibration and noise, and prolong the service life of rotor parts on shaft
Shaft seal:
Pump has a variety of mechanical seals and packing seals to choose to meet the requirement of various applications.
The shaft seal self flushing pipeline ensures the flushing and cooling of the shaft seal mating surface.
Bearing:
Standard SKF heavy-duty maintenance free rolling bearing, grease lubrication, optional thin oil lubrication, suitable for all kinds of harsh conditions, design life of more than 50000 hours.
