Choosing the right pump is essential for efficient wastewater handling, sewage transfer, drainage, dewatering and industrial liquid management. A properly selected pump can improve operating reliability, reduce maintenance requirements and help prevent problems such as clogging, overheating and premature component wear.
For businesses searching for a submersible pump manufacturer in India, it is important to look beyond price. Pump construction, application requirements, flow rate, head, solids handling, material compatibility and after-sales support all play an important role in selecting the right equipment.
Flow Chem Pumps manufactures and supplies industrial submersible pump solutions for sewage, wastewater, drainage, dewatering, sludge, slurry and other demanding applications across India. The company has been involved in pump technology since 2002 and operates an ISO 9001:2015 certified manufacturing facility in Gujarat.
What Is a Submersible Pump?
A submersible pump is designed to operate while completely or partially submerged in the liquid being pumped. Unlike conventional surface-mounted pumps, the motor and pumping components are positioned within the liquid, allowing the pump to push fluid directly from the source to the required discharge point.
Submersible pumps are widely used in:
- Sewage treatment plants
- Effluent treatment plants
- Wastewater treatment systems
- Construction-site dewatering
- Mining and quarry dewatering
- Industrial drainage
- Sludge transfer
- Stormwater removal
- Industrial wastewater handling
The correct pump depends on the characteristics of the liquid and the operating conditions.
Types of Submersible Pumps for Industrial Applications
Different applications require different pump designs. Some of the most common industrial submersible pump categories include sewage pumps, wastewater pumps, drainage pumps, cutter pumps and slurry pumps.
1. Submersible Sewage and Sludge Pumps
Sewage and sludge pumps are designed for applications where the pumped liquid contains suspended solids and organic material.
They are commonly used in:
- Sewage treatment plants
- Municipal wastewater systems
- Sewage sumps
- Sludge transfer systems
- Industrial wastewater facilities
If your application involves sewage or sludge with significant solids content, selecting a pump designed specifically for solids handling is important.

2. Submersible Wastewater Pumps
Wastewater pumps are commonly used for transferring treated or partially treated wastewater in industrial and municipal applications.
They can be suitable for:
- ETP systems
- STP systems
- Industrial wastewater
- Process-water discharge
- Municipal wastewater networks
- Effluent transfer
Flow Chem's wastewater pump range is designed for wastewater and effluent handling applications, with configurations intended for different operating conditions and liquid characteristics.

3. Submersible Drainage Pumps
Drainage pumps are used when unwanted water needs to be removed quickly from a location.
Typical applications include:
- Construction sites
- Basements
- Industrial areas
- Stormwater collection points
- Utility areas
- Waterlogged sites
For projects where the primary requirement is water removal rather than heavy sewage handling, a drainage pump may be more appropriate.

4. Submersible Cutter Pumps
Wastewater can sometimes contain fibrous materials, rags and other solids that can cause conventional pumps to clog.
A cutter pump incorporates a cutting mechanism to reduce certain fibrous or solid materials before they pass through the pumping system.
Cutter pumps can be considered for wastewater applications where clogging from fibrous material is a concern.

5. Submersible Slurry and Agitator Pumps
Slurry applications present different challenges because the pumped liquid may contain abrasive solids.
Mining, mineral processing, industrial waste and other applications may require pumps designed for abrasive slurry handling.
An agitator pump can also help suspend settled solids before pumping, depending on the application and system design.

How to Select the Right Submersible Pump
Selecting a pump should begin with the actual application rather than simply choosing a motor size.
Here are the key factors to evaluate.
1. Flow Rate
Flow rate indicates how much liquid the pump needs to move over a specific period.
It is generally expressed in units such as:
- m³/hr
- L/min
- L/s
Selecting a pump with the appropriate flow capacity helps ensure that the system meets its required pumping performance.
2. Total Head
Total head represents the pressure requirement the pump must overcome to move liquid from the suction location to the discharge point.
The calculation should consider:
- Vertical lifting height
- Pipe length
- Pipe diameter
- Pipe fittings
- Valves
- System pressure
- Friction losses
Choosing a pump based only on flow rate without considering head can result in poor system performance.
3. Solids Size
For sewage, sludge and wastewater applications, solids handling is an important consideration.
The pump should be selected according to the size and type of solids present in the liquid. Incorrect selection may increase the risk of blockage or reduced performance.
4. Liquid Characteristics
The liquid being pumped can affect pump selection significantly.
Consider:
- Temperature
- pH
- Chemical composition
- Suspended solids
- Abrasiveness
- Corrosiveness
- Viscosity
Industrial effluent, sewage and abrasive slurry can require different materials and pump configurations.
5. Operating Hours
A pump operating continuously in a treatment plant has different requirements from a pump used occasionally for construction-site drainage.
Consider whether the pump will operate:
- Continuously
- Intermittently
- Seasonally
- For emergency drainage
- For temporary dewatering
This information helps determine the appropriate pump configuration and motor selection.

Common Mistakes When Selecting a Submersible Pump
Choosing a pump based only on horsepower is one of the most common mistakes.
Other mistakes include:
Selecting the Wrong Flow Rate
A pump that does not meet the required flow can cause delays and poor system performance.
Ignoring Total Head
Even a high-capacity pump may not deliver the required flow if the system head is too high.
Not Checking Solids
Sewage and wastewater containing solids require appropriate solids-handling capabilities.
Ignoring Material Compatibility
Industrial wastewater and chemical-containing liquids may require suitable materials of construction.
Choosing Only on Purchase Price
A lower initial price does not necessarily mean a lower total cost of ownership. Reliability, energy consumption, maintenance and service support should also be considered.
Why Application-Based Pump Selection Matters
There is no single submersible pump that is ideal for every application.
A sewage treatment plant, construction site, mine and industrial effluent plant can have completely different pumping requirements.
Before purchasing a pump, provide the manufacturer with:
- Required flow rate
- Total head
- Liquid type
- Solid size and concentration
- Pumping temperature
- Installation depth
- Pipe size and length
- Operating hours
- Power availability
- Application details
This information allows the manufacturer or technical team to recommend a more suitable pump configuration.
