Vertical Long Shaft Sump Pump
The MK FLOW Vertical Long Shaft Sump Pump is specifically engineered for handling corrosive, abrasive, or slurry-type liquids directly from deep pits, sumps, or underground tanks. Its vertical configuration with a long shaft design allows the pump to operate submerged in the liquid, while the drive motor remains mounted above the tank—preventing motor exposure to fumes or fluid.
⚙️ Working Principle
This is a vertical single-stage centrifugal pump with a long shaft connecting the impeller (located in the fluid) to the motor (mounted above). The shaft is guided by intermediate bearings and bushings, ensuring vibration-free performance even at longer depths. The pump is ideal for continuous-duty applications where fluid levels vary and suction is not practical.
