Horizontal chemical axial flow pump
The horizontal axial flow pump has been designed to handle both highly corrosive and clear liquid in high-flow and low-head applications. Discharge diameter from 200 to 1800 mm( 8 to 72 inches) In MVR water treatment, salt making, alumina, mirabilite, alkali industry, sugar making, seawater desalination and other industries as a transport or forced circulation evaporation pump . A wide range of high-quality materials deal with different medium: stainless steel SS304, SS316, SS316L, 904L, duplex stainless steel CD4MCu, 2205, 2507, Alloy 20, Hastelloy, Titanium, Monel, Nickel...
■ 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.

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.
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.|
