Multi Stage Impeller Pump

Multi-stage impeller pumps have multiple impellers mounted on a single shaft and connected in series. These pumps are equipped with diffusers to efficiently connect the stages. Fluid enters the first chamber at suction line pressure and exits at a slightly elevated pressure. After leaving the first stage, the fluid enters the second stage, where the pressure is further increased. The more stages a pump has, the higher the final discharge pressure. These pumps have the unique ability to generate higher pressures with each additional stage, while maintaining a constant flow range at a given speed. The axial thrust of the impellers is balanced using a balancing disc and seat or a balancing drum arrangement. All impellers are equipped with replaceable wear rings to maintain efficiency. They offer high efficiency, a wide performance range, safe and stable operation, low noise, long life, and easy installation and maintenance.
