How To Choose A Submersible Sewage Pump

The WQ series sewage pump is an efficient and durable submersible pump designed specifically for treating wastewater containing solid particles and fibers. It uses corrosion-resistant materials with strong overcurrent capacity and anti clogging function, suitable for municipal engineering, industrial wastewater treatment, construction site drainage, and agricultural drainage and irrigation fields. Its compact structure, convenient installation, and double end mechanical seal ensure long-term stable operation under high water pressure, making it an indispensable equipment in modern sewage treatment systems.

Choosing a submersible sewage pump requires comprehensive consideration of multiple factors to ensure its efficient and stable operation. The following are several key points to pay attention to when choosing a submersible sewage pump:

Medium characteristics:

Wastewater composition: Understand the solid particles, fibrous substances, and corrosive substances contained in wastewater to select suitable pump materials and impeller designs.

Temperature and viscosity: Confirm the temperature and viscosity of the wastewater and select a pump that is suitable for these conditions.

Flow and head:

Flow rate: Determine the maximum flow rate that the sewage pump needs to process, usually measured in cubic meters (m ³/h) per hour.

Head: Calculate the required head based on the height and transportation distance of the sewage to be lifted, usually in meters (m).

Pump material:

Corrosion resistance: If the wastewater contains corrosive chemicals, choose a pump made of stainless steel or other corrosion-resistant materials.

Wear resistance: When treating wastewater containing sand, gravel or hard particles, choose pumps made of wear-resistant materials.

Structure and type of pump:

Impeller type: Choose an impeller type suitable for treating solid and fibrous substances in wastewater, such as open impeller, semi open impeller, or vortex impeller.

Sealing performance: Ensure good sealing performance of the pump, prevent sewage leakage and motor damage.

Installation and maintenance:

Installation method: Choose vertical, horizontal, or other installation methods based on site conditions to ensure easy installation and small footprint.

Maintenance convenience: Choose models that are easy to maintain and repair to reduce downtime and maintenance costs.

Motor power:

Matching motor power: Select a motor power that matches the flow and head of the pump to ensure that the pump can operate under optimal conditions.

Brand and after-sales service:

Reliable brand: Choose a reputable and reliable brand to ensure stable product performance.

After sales service: Consider the manufacturer's after-sales service and technical support to ensure the long-term use and maintenance of the pump.

By selecting based on the above factors, it can be ensured that the submersible sewage pump operates efficiently and reliably in practical use.
