Leading Manufacturer & Supplier
Submersible Pumps for the Marine Industry
From shipyard drainage to dock dewatering, bilge water handling, seawater transfer, and marine wastewater management, JB Pumps manufactures heavy-duty submersible pumps built for reliable performance in demanding marine environments.
Built for the Demands of Marine Operations
Marine environments are tough on pumping equipment. Saltwater exposure, continuous moisture, sludge, sand, oil-mixed water, and confined installation spaces can quickly damage ordinary pumps. A pump failure in a shipyard, dock, port, or marine facility can delay operations, affect safety, increase maintenance costs, and create wastewater handling issues.
At JB Pumps India Pvt. Ltd., we manufacture submersible pumps engineered for marine industry applications. Every pump is designed with strong sealing, corrosion-resistant material options, rugged motor protection, and dependable hydraulic performance. Whether you are handling dock water, bilge water, seawater, marine sludge, stormwater, or shipyard wastewater, our pumps are built to perform reliably in harsh marine conditions.

Common Marine Industry Pumping Challenges - and How We Solve Them
Challenge 01
Corrosion from seawater and saline conditions
Marine pumps are constantly exposed to saltwater, humid air, and corrosive site conditions. JB Pumps offers SS 304, SS 316, epoxy-coated, and corrosion-resistant pump configurations to improve service life in saline environments.
Challenge 02
Motor safety in wet and submerged conditions
Marine pumping applications often require pumps to work fully submerged in harsh and dirty water. JB Pumps uses IP68-rated motor housings, robust sealing systems, and heavy-duty cable entry protection to reduce the risk of water ingress.
Challenge 03
Continuous dock and shipyard dewatering
Shipyards and dry docks need reliable drainage to keep work areas safe and operational. Our submersible dewatering pumps are built for continuous operation, stable flow, and dependable performance in collection pits and low-lying marine areas.
Challenge 04
Dirty water with oil, sludge, and solids
Bilge water, dock water, and shipyard wastewater often contain oil traces, sand, rust particles, sludge, and suspended solids. Our sewage, sludge, and slurry pumps are designed to handle contaminated water and solids without frequent clogging.
Challenge 05
Abrasive sand and silt in harbour
water
water
Port and harbour water can carry sand, silt, shells, and abrasive particles that wear out standard impellers quickly. JB Pumps recommends hardened impellers and heavy-duty hydraulic components for abrasive marine water handling.
Challenge 06
Emergency pumping during monsoon or flooding
Coastal facilities, docks, and shipyards face sudden water accumulation during heavy rainfall, high tides, or operational emergencies. JB Pumps supports fast delivery, rental pump availability, and technical assistance for urgent dewatering needs.
