A single suction pump is a type of pump that has one end for suction and the other for discharge. A single-stage single-suction centrifugal pump is one of the simplest types of centrifugal pumps. Single-stage means that there is only one impeller inside the pump, and single-suction means that water is drawn in from one side of the impeller. This type of pump generally has a smaller flow rate and is mostly classified as a small pump.
Single suction pump, a type of pump that draws in from one end and discharges from the other. A single-stage single suction centrifugal pump is one of the simplest types of centrifugal pumps. Single-stage refers to having only one impeller inside the pump, and single suction means that water is drawn in from one side of the impeller. This type of pump generally has a smaller flow rate and is mostly classified as a small pump.
The single suction pump has a horizontal axial intake and radial discharge upwards. The pump has a suspended structure, and during maintenance, there is no need to disassemble the inlet and outlet pipelines; the rotor components can be removed for maintenance. The pump is connected to the motor via a standard elastic coupling or an extended elastic coupling, and the shaft seal uses soft packing. The bearing is a single-row radial ball bearing, lubricated with oil. From the motor end, the pump rotates in a clockwise direction.
When the single suction pump starts, the pump shaft drives the impeller to rotate at high speed, forcing the liquid pre-filled between the blades to rotate. Under the influence of inertial centrifugal force, the liquid moves radially from the center of the impeller to the outer periphery. During its movement through the impeller, the liquid gains energy, increasing its static pressure energy and flow velocity. When the liquid leaves the impeller and enters the pump casing, it slows down due to the gradually expanding flow path inside the casing, with some kinetic energy converted into static pressure energy, flowing tangentially into the discharge pipeline. Therefore, the volute casing not only collects the liquid flowing out of the impeller but also acts as an energy conversion device. As the liquid is thrown from the center of the impeller to the outer periphery, a low-pressure zone forms at the center of the impeller. Under the influence of the potential energy difference between the liquid level in the reservoir and the center of the impeller, liquid is drawn into the center of the impeller. With continuous operation of the impeller, liquid is continuously drawn in and discharged. The mechanical energy gained by liquid in a centrifugal pump manifests as an increase in static pressure energy.
