Axial Flow Propeller Pump

With optimized design and advanced hydraulic models, our axial flow propeller pumps have a wide performance range that can cover the needs for most of our clients. We may also offer tailored made propeller pumps to meet the different requirements, below are the typical specifications of our axial flow pumps.

■ Capacity: Q=250～30,000（m³/h）

■ Head: H=8～1.5 (m)

■ Speed range: n=180～1450 rpm

■ Fluid density: ≤1.5

■ Fluid temperature: 0～180℃

■ Fluid viscosity: ≤600(mm2/s)

■ Pump diameter: Ф200mm~3000 mm

The axial flow propeller pumps are mainly used for large amount water transferring or circulation purposes, which always require big flow rate with low discharge pressure.

• ■ Propeller blades are adjustable.

• ■ Slow speed design, low NPSHr value.

• ■ Elbow flow patch resulting in superior hydraulic performance.

• ■ Pipe hung mounting, no baseplate is needed.

• ■ API682 flush plans enable the sealing performance.

• ■ Cartridge double mechenical seal, leakage free.

Due to the large flow rate and continuous duty operation of axial flow propeller pumps, they must be designed with robust structure to enable the smooth operation.

Structural drawing of propeller pumps:

	K-pipe hung arrangement  No baseplate for both pump and motor,no  expansion  joint on pipe. The Axial Flow Propeller 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 axial propeller pump,pump is hung on the pipe,no expansion joint on pipe.For big axial 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 axial propeller pump and electric 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 the propeller pumps.

The material of construction of propeller pumps can be highly customized according to the specific requirements of application, we offer wide range of materials for our axial flow propeller pumps.

Thanks to wide flow rate range of propeller pumps, they can be widely used in various industries, below are some typical applications where our axial flow pumps are used.

Irrigation: 

The outstanding capability of big flow rate and low head of propeller pumps makes them suitable for deliverying large volume of water for farm irrigation purposes.

Flood Control: 

Due to the feature of pumping big amount of water in a short period of time, the axial propeller pumps are popularly used for flood water control.

Cooling Water Circulation: 

Due to the feature of big flow rate and low discharge head, the axial flow propeller pumps are ideal for cooling water circulation pumps in various applications.

Forced circulation Systems:

Due to the features of high efficiency and and flow rate, the axial flow pumps are suitable to work as forced circulation pumps in many industries where the forced circulation systems are required.

Wastewater Treatment: 

In waste water evaporation industry, it requires big flow pumps to handle the forced circulation in their evaporators, the axial flow propeller pumps are the ideal for such application where forced circulation pumps are required.

Aquaculture: 

The fish and shrimp farms always require to exchange the water in the farms in a short period of time, our axial flow propeller pumps perfectly match this need and so they are widely used in aquacalture.
