Submersible Waste Water Pump — Effluent Pump Manufacturer India
Heavy-duty submersible waste water pumps for industrial effluent treatment, municipal wastewater, ETP/STP discharge, and contaminated water transfer. Flow rates up to 200 m³/hr, solid handling up to 50mm.
About Submersible Waste Water Pumps
Flow Chem submersible waste water pumps are engineered for transferring treated and partially treated wastewater in effluent treatment plants (ETP), sewage treatment plants (STP), industrial process water systems, and municipal wastewater networks. They bridge the gap between clean water drainage pumps and raw sewage pumps.
Manufactured at our ISO 9001:2015 certified facility in Gujarat, these pumps are designed for continuous duty in corrosive and mildly contaminated environments. Available in cast iron as standard, with stainless steel and special alloy options for aggressive chemical and high-chloride effluent applications.
Flow Chem waste water pumps handle a wider range of water quality than standard drainage pumps — including treated effluent, industrial process water, STP secondary effluent, and mildly contaminated stormwater — making them the preferred choice for ETP inlet/outlet pumping, tertiary treatment transfer, and industrial recirculation applications.
Key Features
Designed for reliable operation in contaminated and corrosive water environments
Cast iron standard with optional stainless steel (SS304/SS316) and special alloy construction for aggressive chemical effluents. Handles acidic, alkaline, and high-chloride wastewater without accelerated corrosion.
Semi-open vortex impeller handles suspended solids up to 50mm without clogging. Impeller design minimizes contact with solids, reducing wear and maintaining hydraulic efficiency over extended operating periods.
High-efficiency Class F insulation motors with IE2/IE3 efficiency ratings. Lower energy consumption reduces operating costs for continuous 24/7 ETP and STP applications where pumps run for thousands of hours annually.
Double mechanical seals with oil chamber in standard configuration. For aggressive effluents, external flush seal arrangements are available. Silicon carbide, tungsten carbide, and ceramic seal face options.
Compatible with float switches, conductivity probes, and ultrasonic level sensors for automatic pump operation. Level control systems prevent dry running and optimize pump cycling in sump and wet-well applications.
Built-in thermal overload protection, moisture ingress sensors, and bearing temperature monitoring. Automatic motor shutdown on fault conditions prevents catastrophic failure and protects your investment.

Applications
Flow Chem waste water pumps serve critical roles in industrial and municipal water treatment infrastructure
Effluent Treatment Plants (ETP)
Inlet raw effluent pumping, inter-stage transfer between treatment units, and final treated effluent discharge. Handles mixed industrial wastewater from chemical, pharma, textile, and process industries.
Sewage Treatment Plants (STP)
Secondary and tertiary treated effluent transfer, return sludge pumping, and final discharge to water bodies or reuse systems. For raw sewage inlet pumping, see our sewage sludge pumps.
Chemical and Pharma Industry
Transfer of treated or partially treated chemical effluent containing residual acids, alkalis, and solvents. Stainless steel construction options for corrosion resistance. External flush seals for crystalline solutions.
Textile and Dyeing Industry
Dye bath effluent transfer and ETP circulation pumping. Handles colored wastewater with suspended dye particles, chemicals, and dissolved solids. High-temperature models available for hot dye bath discharge.
Food and Beverage Industry
Process wastewater, wash water, and effluent transfer from food processing plants. Handles organic solids, food particles, and fats. For waste containing fibrous material like vegetable waste, consider cutter pumps.
Construction Site Runoff
Pumping contaminated stormwater runoff from construction sites containing sediment, cement wash, and construction chemicals. For clean water dewatering, our drainage pumps offer higher flow rates.
Municipal Wastewater
Lift station pumping for municipal sewer networks, storm water pumping stations, and treated effluent discharge to rivers or reuse systems. Handles mixed municipal wastewater with moderate solids content.
Water Reuse and Recycling
Transfer of treated wastewater for irrigation, industrial cooling, toilet flushing, and process water reuse. SS316 construction options prevent re-contamination of recycled water. Essential for Zero Liquid Discharge (ZLD) systems.

Frequently Asked Questions
What is the difference between a waste water pump and a sewage pump?
A waste water pump is designed for treated or partially treated effluent — ETP discharge, STP secondary effluent, industrial process water. It offers corrosion-resistant material options and energy-efficient motors for continuous operation. A sewage pump is designed for raw wastewater with heavy organic solids (up to 60mm) and is better suited for raw sewage inlet pumping.
Can waste water pumps handle acidic or corrosive effluent?
Yes. Flow Chem waste water pumps are available in SS304, SS316, and duplex stainless steel construction for corrosive applications. We also offer epoxy coatings and special alloy options. Our team provides free chemical compatibility assessment to recommend the right material for your effluent chemistry.
What is the typical lifespan of a waste water pump in ETP/STP?
With proper maintenance, Flow Chem waste water pumps typically last 8-15 years in ETP/STP applications. 4-pole models (1450 RPM) generally have longer service life due to reduced rotational speed and wear. Annual maintenance — seal inspection, impeller check, oil change — significantly extends pump life.
Can waste water pumps handle hot effluent?
Yes. Flow Chem offers hot effluent pump models rated for temperatures up to 90°C. Standard models handle up to 60°C. For high-temperature applications like dye bath discharge or boiler blowdown, specify temperature requirements when requesting a quote.
Do you provide installation and commissioning for ETP/STP pumps?
Yes, Flow Chem provides professional pump installation services specifically for ETP/STP projects. This includes site survey, sump design, pump installation, piping, electrical, commissioning, and operator training. Available for greenfield projects and pump upgrades.
