With solid handling capacity up to 60mm and flow rates up to 130 m³/hr, Flow Chem sewage pumps are the trusted choice for municipal corporations, industrial plants, and construction companies across India.
Key Features
Engineered for reliable performance in the harshest sewage and sludge conditions
Double mechanical seals with oil chamber provide primary and secondary sealing to protect the motor from water ingress. Each seal assembly is pressure-tested before dispatch.
Premium-grade cast iron pump casing, impeller, and wear plate for maximum durability in corrosive and abrasive sewage environments. Extended service life with minimal maintenance.
Class F insulation motors rated for continuous duty. Available in 2-pole (2900 RPM) for compact installations and 4-pole (1450 RPM) for reduced wear and extended life.
Semi-open or vortex impeller design handles solids up to 60mm without clogging. Passes fibrous materials, rags, and debris commonly found in raw sewage and sludge.
Built-in thermal overload protection with automatic motor winding sensors. Prevents motor damage from overheating during dry running or overload conditions.
Compatible with guide rail auto-coupling systems for easy installation and removal without entering the sump. Reduces maintenance downtime and improves operator safety.

Applications
Flow Chem sewage pumps handle demanding applications across India's municipal and industrial sectors
Sewage Treatment Plants
Primary and secondary sewage pumping for municipal STPs. Handles raw sewage, screenings, and settled sludge in inlet and recirculation pumping stations.
Septic Tank Pumping
Efficient pumping of septic tank effluent and sludge for residential complexes, commercial buildings, and institutional facilities.
Chemical Industry
Handling corrosive and abrasive industrial wastewater in chemical plants. Special material options available for acidic and alkaline effluent.
Leather Industry
Heavy sludge and effluent pumping for tanneries and leather processing plants. Handles high-solids wastewater with lime, chromium, and organic matter.
Kitchen Waste
Food processing waste, hotel kitchen effluent, and restaurant grease trap waste. Handles organic solids, food particles, and FOG (fats, oils, grease).
Hospital Waste
Medical wastewater and bio-waste handling for hospitals and healthcare facilities. Handles sanitary waste, pharmaceutical residues, and biological sludge.
Construction Sites
Construction dewatering and site drainage pumping. Handles muddy water, concrete wash water, and site runoff with solids and debris.
Manhole Sewer
Lift station pumping for municipal sewer networks. Handles raw sewage from manholes and collection chambers for gravity-fed sewer systems.
2-Pole vs 4-Pole: Which Is Right for You?
Choose the right motor speed for your application requirements
2-Pole Pumps (2900 RPM)
Best for: High flow applications where space is limited and compact pump size is important.
Higher speed means smaller pump dimensions for the same flow rate. Ideal for sewage lift stations, transfer pumping, and applications where installation space in the sump is restricted. Higher velocity provides better self-cleaning action in the impeller.
Typical uses: Municipal sewage lift stations, STP inlet pumping, septic tank pumping, building basement drainage.
4-Pole Pumps (1450 RPM)
Best for: Continuous duty applications where extended service life and reduced maintenance are priorities.
Lower speed means reduced wear on seals, bearings, and impellers. Ideal for 24/7 operation in sewage treatment plants. Reduced vibration and noise. Lower NPSH requirement makes them suitable for installations with limited suction head.
Typical uses: STP recirculation pumps, sludge return pumps, continuous duty effluent transfer, industrial wastewater.

Frequently Asked Questions
What size solids can Flow Chem sewage pumps handle?
Our sewage pumps can handle solids up to 60mm depending on the model and impeller configuration. Semi-open non-clog impellers are designed to pass fibrous materials, rags, and debris without clogging.
Should I choose a 2-pole or 4-pole sewage pump?
Choose 2-pole (2900 RPM) for compact installations requiring high flow rates. Choose 4-pole (1450 RPM) for continuous 24/7 duty where reduced wear and extended service life are priorities. Contact our team for project-specific recommendations.
What is the typical lifespan of a Flow Chem sewage pump?
With proper installation and maintenance, Flow Chem sewage pumps typically last 8-15 years. 4-pole models tend to have longer service life due to lower operating speed and reduced wear. Regular maintenance significantly extends pump life.
Can Flow Chem pumps handle corrosive wastewater?
Yes, we offer special material options including GI (galvanized iron), GMS (galvanized mild steel), and stainless steel construction for corrosive applications in chemical, pharmaceutical, and leather industries.
Do you provide installation services?
Yes, Flow Chem provides professional pump installation services across India. Our team handles site assessment, pit preparation, pump installation, electrical connections, commissioning, and operator training. Learn about our installation services.
