Types of Impellers for Submersible Water Pumps
There are several types of impellers available for submersible water pumps. However, the three most commonly used types are enclosed impellers, vortex impellers, and cutter impellers.
Enclosed Impeller
The enclosed impeller is the most widely used type for water pumps. It has a closed design with internal grooves that allow for easy water entry. This type of impeller is primarily used for regular pumps and 1-stage industrial water pumps.
Enclosed impellers are relatively inexpensive and provide durable and robust water pumping. However, they can be easily damaged if the water source contains debris or small sand particles. They are suitable for household pumps and industrial pumps with a power capacity below 37KW.
Vortex Impeller
The vortex impeller has a vortex-shaped design and is commonly known as an open impeller. It is widely used in sewage pumps. The main advantage of the vortex impeller is its ability to pump mud or water mixed with mud, including small debris, without clogging.
However, vortex impellers are not suitable for pumping wastewater mixed with larger debris. They are primarily used for submerged industrial pumps with a power capacity of 0.75 KW – 75 KW.
Cutter Impeller
The cutter impeller is specifically designed for cutting soft materials or materials that can cause blockage in the pumps. It is equipped with cutting impellers and cutting grooves to quickly process and suck in the material.
Using a pump with a cutter impeller is highly effective for handling wastewater containing waste, clothes, and flexible materials. It ensures optimal operation without breakdowns.
When to Use Enclosed Impeller, Vortex Impeller, and Cutter Impeller?
- In wastewater environments with minimal solid particles, enclosed impeller submersible pumps are recommended.
- In wastewater environments with relatively few solids and impurities, open impeller submersible pumps can be used.
- Vortex impeller pumps are suitable for pumping wastewater mixed with diluted mud, debris, suspended solids, etc.
- Cutter impeller pumps are ideal for dense wastewater, waste, sand, gravel, etc.
