waterpowermodel

The optimized hydraulic model not only enables the pump to have excellent hydraulic performance, but also eliminates the problem of axial force (theoretically) that troubles the operation of pumps, especially large pumps. The pump body, pump cover, and impeller are precision cast, and the smooth flow surface improves the anti cavitation performance and efficiency of the pump.

Pump shaftseal

According to the conveying medium or user requirements, use packing seals or mechanical seals without being restricted by steering. For packing seals, there is sufficient space for replacing the packing.

working conditions

1、 The allowable work pressure is2.5MPa:Pump inlet pressure+pump lift≤2.5MPaAccording to the pressure borne by the pump casing, the material of the pump body and pump cover is gray cast iron（1.6MPa）Ductile iron（2.0 MPa）、Cast steel（2.5MPa）Please indicate the pressure bearing condition or material of the pump when placing an order.

2、 Medium: Temperature≤105°CClear water or other liquids with physical and chemical properties similar to clear water (solid particles)≤80mg/L）.

Matchingbearing

1、 Sealed rolling bearings lubricated with grease are easy to maintain and have a long operating time.

2、 Equipped with a constant oil level oil cup, it can also be lubricated with thin oil.

3、 Choose imported products（SKF、NSK、NTN）High quality bearings, smooth operation, low noise, useLong time.

water pumpstructure

The pump has a compact structure, good stability, and is designed with a pump casing that is split open. Both imports and exports are located on the pump body. During maintenance, the pump cover needs to be lifted out, and the rotor components can be removed for maintenance operations without dismantling the pipelines, which is quite convenient.

The electric motor (driver) can be installed on the left or right end as needed, making it convenient for on-site installation. Structurally shortening the axial dimensions of rotor components results in better shaft rigidity and more stable and reliable operation. There is a pump body sealing ring, and the impeller sealing ring is an optional component. The sealing ring can be replaced after wear, reducing operation and maintenance costs.
