Product Description

Biref 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..

Parameters:

Flow rate:	Q=250~55000(m³/h)
Total head:	H=8~1.5 (m)
Speed:	n=180~1450rpm
Fluid s.g.:	γ ≤1.5
Fluid temperature:	T=0~180ºC
Fluid viscosity:	ν ≤600(mm2/s)
Pump diameter:	Ф250mm~1800mm

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.

Structure drawing is as below

The instruction of installation methods:

K suspended installation

The pump and motor are totally articulated, the pump and motor are no need basis, and there are no expansion joint and transport by the triangle belt. The caliber is 300~500mm, only the motor affiance is under 55kw have this installation type.

E half suspended installation

There are no basis at the installation scene, and the pipe bear the weight of pump body. You'd better design a floatable bearing for the pump that caliber≥700 at the horizontal direction and the connection pipe. We only recommend triangular belt transmission and gamble transmission, no expansion joint in the pipe connected with the pump.

F horizontal installation

The base plate is needed when install pump and motor. If the working condition is high temperature, the pipe connected with the pump body need the expansion joint, the pump and motor could translated by the triangular belt of directly transmission.

The above three installation ways should deploy a short joint in accordance with the pipeline connected with the pump, it's easy to replace the impeller, mechanic sealing and so on.
