Horizontal chemical axial flow pump

■ 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=0～180℃

■ Fluid viscosity: ν ≤600(mm2/s)

■ Pump diameter: Ф200mm~1800mm

• ■ Adjustable propeller blade for different working requirements,expand the application range and improve the versatility of pump.

• ■ Slow speed design,no damage to crystal medium,small NPSH,smooth operation.

• ■ This pump type, is also known as elbow pump, its main body adopts elbow structure, adopts modular splicing assembly welding or integral forging molding, good hydraulic performance.

• ■ Suspension installation, no pump base plate, no expansion joint.

• ■ Pre-assembled bearing for easy assembly and maintenance.

• ■ Slight vibration, low noise, smooth operation, high efficiency and energy-saving.

1. Types of shaft seals available:

• ■ Soft packing

• ■ Single mechanical seal

• ■ Double mechanical seal

Mechanical seal and packing seal can be interchangeable 

2. Center line mounted pump casing

3. The installation and transmission of pump has a variety of forms.

4. Pump and motor can be used triangle belt transmission, gear transmission, direct transmission.The big diameter large capacity pump should adopt the universal joint transmission.

Structure drawing is as below

	K-pipe hung arrangement  No baseplate for both pump and motor,no  expansion  joint on pipe. Pump is driven by motor through V-belts.This arrangement is only applicable  for the  pump   diameter from 300-500mm and motor  capacity  below 55Kw.
	E-half pipe hung arrangement No baseplate for pump,pump is hung on the pipe,no expansion joint on pipe.For pumps above 700mm diameter,there must be a fluctuating frame at the horizontal pipe connecting the pump.Only V-belts and universal joint are recommended as the transmission method for this arrangement.
	F-horizontal arrangement Baseplate is required for both pump and motor.An expansion joint on the pipe is also required for high temperature applications.Transmission methods can be V-belts and direct coupled.
For easy maintenance purpose,the above mentioned arrangements require a casing between horizontal pipe and pump.

ZW chemical axial flow pump is mainly applicable for the applications of big flow rate and low total head, like force circulation pump for evaporator systems:

• ■ MVR water treatment evaporation concentration process

• ■ Single effect and multi effect forced evaporation circulating pump for vacuum salt making

• ■ Forced evaporation circulating pump for alumina industry  

• ■ Single - effect and multi - effect forced evaporation circulating pump for mirabilite production  

• ■ Forced evaporation circulating pump for alkali industry

• ■ Forced evaporation circulating pump for sugar industry  

• ■ Sea water desalination evaporation circulating pump

• ■ Chemical process industry

• ■ Water and wastewater treatment
