Brief introduction
Owns 8 patent technologies, the comprehensive performance of ZW axial flow pump ranks in top among all the local competitors in China. It is a product of provincial achievement ,and it gained the award of technology progress of China machinery industry. There are plenty of real sales achievements for every single specification from diameter 250 mm to 1500 mm. ZW axial flow pump is widely used as forced circulation pump in the applications of big flow rate with low total head,for example: MVR water treatment, vacuum salt, aluminum oxide, sodium sulfate, chlorine-alkali, sugar making,seawater desalination
Forced Circulation pump / Vertical Propeller Elbow Pump / Mixed Flow Industrial pump is mainly applicable for the applications of big flow rate and low total head, like force circulation pump for evaporator systems:
■Salt-making force circulation pump
■Sodium sulfate force circulation pump
■Aluminum oxide force circulation pump
■Sugar-making force circulation pump
■Chlorine alkali force circulation pump
■MVR water treatment force circulation pump

Long working life pump's Structure:
Elbow structure for pump body,piece-welded body and casted body for selection.
Pump impeller is cantilever type with spherical hub,impeller blades are adjustable.
Pump shaft adopts butt welding workmanship,the wetted parts or possible wetted parts are made from stainless steel or other corrosive materials.
Mechanical seal and packing seal can be interchangeable.
Adopting cartridge mechanical seal,reliable and easy for maintenance.
Enlarged cylinder type bearing housing with oil level glass and oil filler,which extends the bearing life and interval of lubricant changing.
Pump and be driven by motor through V-belts,gear box or directly through couplings. For pipe hung pump,the universal joint transmission must be adopted if the motor ≥200kW.

ZW pump installation solution
K-Hanging Installation
The pump and the motor are integrally hinged. The pump and the motor do not need a foundation and are driven by a V-belt.Only the pump with a diameter of 200-500 mm and a motor power of ≤ 45 kW can be installed like this way.
F Horizontal installation
Both the pump and the motor need to be installed with base. The pipe connected to the pump body needs to be provided with expansion joints. The pump and motor can be equipped with V-belt or direct transmission.
E Hanging installation Pump + motor + pulley
There is no foundation for installing the on-site pump. The weight of the pump body is supported by the pipeline. The diameter of the impeller is more than 700. The pump is connected to the pump in the horizontal direction and the pump is preferably supported by the upper and lower floating supports. In the transmission mode, only the V-belt drive or the universal joint drive is recommended. The pipe connected to the pump is not provided with an expansion joint.
