Submersible Drainage Pump — Dewatering Pump Manufacturer India
High-performance submersible drainage pumps for construction dewatering, flooded basements, tunneling, mining, and open pit drainage. Flow rates up to 250 m³/hr, heads up to 35 meters.
About Submersible Drainage Pumps
Flow Chem submersible drainage pumps are designed for efficient removal of clean water, rainwater, and lightly contaminated water from construction sites, flooded areas, tunnels, mines, and open pits. Built for the toughest dewatering conditions in India.
Manufactured at our ISO 9001:2015 certified facility in Gujarat, these pumps feature heavy-duty cast iron construction, vortex or semi-open impeller designs that handle suspended solids, and motors rated for continuous duty in demanding environments. Available in single-phase and three-phase configurations.
Unlike sewage pumps designed for raw wastewater, drainage pumps are optimized for clean to mildly turbid water — making them ideal for construction site pumping, basement flood control, and surface water management where the primary concern is high volume water removal.
Key Features
Engineered for reliable, high-volume water removal in the toughest conditions
Flow rates up to 250 m³/hr with heads up to 35 meters. Efficient hydraulic design ensures maximum water removal with minimum energy consumption. Volute casing optimized for high-volume drainage.
Premium-grade cast iron pump casing, impeller, and wear plate for maximum durability on construction sites and mining operations. Handles abrasives like sand, silt, and small gravel without damage.
Available in both single-phase (220V) and three-phase (415V) motor options. Single-phase models ideal for residential and small commercial use. Three-phase for heavy-duty industrial and construction applications.
Double mechanical seals with oil chamber provide reliable protection against water ingress. Carbon-ceramic or silicon carbide seal faces for extended service life in abrasive drainage conditions.
Vortex impeller design available for applications with suspended solids and debris. The non-clogging vortex action minimizes contact between impeller and solids, reducing wear and maintenance.
Built-in thermal overload protection with automatic motor winding sensors. Prevents motor damage from overheating during dry running, overload, or high-ambient temperature conditions.

Applications
Flow Chem drainage pumps handle demanding water removal across India's construction, mining, and infrastructure sectors
Construction Site Dewatering
Removing groundwater and rainwater from excavations, foundations, trenches, and basement construction. Essential for keeping construction sites dry and workable during monsoon and high water table conditions.
Flooded Basement & Cellar
Emergency flood water removal from basements, cellars, underground parking, and below-grade structures. Single-phase models are ideal for residential and small commercial buildings.
Mining and Excavation
Open pit mine dewatering, tunnel face pumping, and underground mine drainage. For heavy slurry and sediment-laden water, our agitator slurry pumps provide superior solids handling.
Tunneling and Underground Works
Tunnel face dewatering during metro, road tunnel, and infrastructure tunnel construction. Compact pump designs fit in confined tunnel spaces while delivering high flow rates for rapid water removal.
Surface Water Management
Drainage of accumulated rainwater from open fields, low-lying areas, storm water collection pits, and reservoirs. For large-scale storm water pumping, our waste water pumps offer higher capacities.
Industrial Plant Drainage
Process water circulation, cooling water drainage, and effluent transfer in industrial plants. For contaminated wastewater with organic solids, see our sewage sludge pumps.
Swimming Pool & Fountain
Pool emptying, fountain water recirculation, and water feature drainage. Clean water handling with minimal maintenance requirements. Corrosion-resistant options available for chlorinated pool water.
Agricultural Drainage
Field drainage during monsoon, irrigation canal pumping, and pond water management. Cost-effective single-phase models available for agricultural use where three-phase power is not accessible.

Frequently Asked Questions
What is the difference between a drainage pump and a sewage pump?
A drainage pump is designed for clean to mildly turbid water — construction sites, basements, tunnels, mining. It handles sand and silt but not large organic solids. A sewage pump is designed for raw wastewater with solids up to 60mm — STPs, septic tanks, municipal sewage. For contaminated water with both solids and fibrous material, a cutter pump may be needed.
Can drainage pumps handle dirty muddy water?
Yes, Flow Chem drainage pumps handle muddy water with suspended sand, silt, and small debris (up to 25mm depending on model). For water with heavy sediment or thick slurry that needs agitation, our agitator slurry pumps are specifically designed for that purpose.
Do you have single-phase drainage pumps for residential use?
Yes, Flow Chem offers single-phase (220V) drainage pumps from 0.5 HP to 3 HP — ideal for basement sumps, residential flood control, garden drainage, and small construction projects where three-phase power is not available. Contact us for model recommendations.
How do I size a drainage pump for my construction site?
Key factors: water inflow rate (liters/minute), vertical lift (head), horizontal distance, pipe friction losses, and solids content. Our engineering team provides free pump sizing based on your site conditions. Contact us with your requirements.
Do you provide installation and commissioning services?
Yes, Flow Chem provides professional pump installation services across India. Our team handles site assessment, sump design, pump installation, electrical connections, commissioning, and operator training. Available for projects of all sizes.
