In municipal, agricultural, and industrial operations, moving large volumes of water or abrasive fluids demands reliable and durable machinery. As an established industrial and submersible pump manufacturer in China, Kairun Pump provides engineering-grade solutions designed to streamline your water management processes. Whether you are managing flood control drainage, municipal wastewater treatment, or mine tailings transport, our products offer the hydraulic output and continuous operation required for demanding environments. We focus on wear-resistant metallurgy, anti-clogging impeller profiles, and low-maintenance power ends to reduce your total cost of ownership.
We supply a diverse range of machinery to pump, mix, and filter fluid media:
Submersible Axial & Mixed Flow Pumps: High-flow, low-head pumps built for flood relief, municipal drainage stations, and agricultural irrigation.
Submersible Sewage & Mud Pumps: Engineered with wide-channel impellers to handle raw sewage, municipal effluents, and solids-laden wastewater without clogging.
Slurry & Dredging Pumps: Heavy-duty pumps constructed with high-chrome alloys and elastomer linings to handle abrasive mud, mineral sand, and mine tailings.
Submersible Mixers & Aerators: Designed to homogenize industrial sludge, prevent sedimentation, and introduce oxygen in activated sludge processes.
Wastewater Screening & Gates: Static flat screens (such as PG/PW screens), rotary bar screens, and steel water control gates to protect pumps and clarify intake flows.
Water-Optimized Designs: Our engineers utilize advanced hydraulic modeling to shape impellers and casings, maximizing flow efficiency and reducing power usage.
High Material Durability: We offer custom metallurgies—including duplex stainless steel, cast iron, and high-chromium white irons—to match the chemical and abrasive properties of the fluid.
Integral Safety Protections: Submersible motors can be equipped with temperature-rise sensors and oil-chamber moisture detectors to protect the stator and bearings from damage.
A: Yes, we specialize in custom manufacturing, transformation projects, and non-standard product customization. We can adjust the hydraulic performance (flow and head), motor insulation class, discharge size, and metallurgy to fit your precise technical drawings.
A: We select materials based on the liquid's pH, chemical composition, and solid concentration. Options include various grades of stainless steel (SS304, SS316, SS316L, Duplex), high-chrome alloys, and protective coatings to prevent premature corrosion and wear.
A: Our submersible motors are built with multiple safety sensors. These typically include leakage probes in the oil chamber to detect mechanical seal failure, and thermal protection switches in the stator windings to prevent motor burnout under abnormal conditions.
