Submersible Archimedes Screw Pump – Working, Features & Advantages

Submersible Archimedes Screw Pump – Working, Features & Advantages

A submersible Archimedes screw pump is a versatile positive displacement pump. The pump finds numerous applications such as irrigation, oil skimming, emergency pumping of hydrocarbons of all viscosity and emulsion, tank cleaning, sludge pumping, bitumen pumping, offloading, transfer pump on oil skimming systems, ballasting, etc.

 

Working of a Submersible Archimedes Screw Pump

As the name suggests this pump can be submerged into the water/medium. The pump is designed for gentle pumping action. The pump consists of a screw which on rotation scoops up some amount of fluid. The fluid is trapped in the space between screw threads. The rotational movement of the screw creates a positive displacement suction to push the fluid ahead.

 

Features

Submersible Archimedes screw pump has some unique features that make it suitable for wide applications. The key features are:

• Robust, simple, and clog-free design

• Operational in hazardous zone

• Wide capacity range

• High efficiency

• Low maintenance

• Low operational cost

• Long life span

• Minimal wear

• Self-adjusting capacity as per influent flow

• Low rotation speed

• No issue of cavitation

 

Advantages

The design and working principle of the Archimedes screw pump results in six important advantages, which are:

 

• Reliable: The simple design, robust structure, and low rpm allow the pump to operate for years without problem.

• Capacity: The pump is capable of lifting floating debris and heavy solids. The large passage between the flights facilitates load-carrying capacity without clogging. The pump handles fluids having varying viscosities.

• Dry Run: The Archimedes screw pump can operate when there is no fluid at the inlet. The lower bearing does not require cooling.

• Rotational Speed: The pump rotates slowly, thereby mitigating the issue of further emulsification during pumping. Also, the large opening between flights and slow rotational speed facilitates maintaining the biological flock in an STP.

• Maintenance: The Archimedes screw pump requires negligible maintenance compared to other pumps. The pump maintenance does not require highly-skilled personnel. The ease of maintenance is vital in remote locations. 

• Life Span: These pumps usually have a life span of 20-40 years. They are suitable for working in harsh environmental conditions.

 

The submersible Archimedes screw pump is a versatile, high-performance, submersible screw pump that has many advantages over other pumps. The pump is commonly made of mild steel with an epoxy coating. The design and construction of the pump assure trouble-free operations for decades.
