Slurry pumps belong to the category of centrifugal pumps. Slurry pump refers to a kind of machine that increases the energy of solid and liquid mixed medium by means of centrifugal force.

Centrifugal pumps work by rotating the impeller to cause centrifugal motion of water. Before the pump is started, the pump casing and the suction pipe must be filled with water, and then the motor is started, so that the pump shaft drives the impeller and the water to rotate at a high speed. into the pressurized water line of the pump.

The basic structure of a centrifugal pump is composed of eight parts, namely: impeller, pump body, pump cover, water retaining ring, pump shaft, bearing, sealing ring, stuffing box, and axial force balance device.

1. The impeller is the core part of the centrifugal pump. It has a high speed and a large output force.

2. The pump body is also called the pump casing, which is the main body of the pump. It plays the role of supporting and fixing, and is connected with the bracket on which the bearing is installed.

3. The function of the pump shaft is to connect the motor with the coupling and transmit the torque of the motor to the impeller, so it is the main component for transmitting mechanical energy.

4. The sealing ring is also called the leakage reducing ring.

5. The stuffing box is mainly made of stuffing, so that the water flow in the pump does not flow to the outside and the outside air does not enter the pump. Always maintain a vacuum inside the pump! When the friction between the pump shaft and the packing generates heat, the water seal pipe is used to inject water into the water seal ring to cool the packing!

6. Axial force balance device. During the operation of the centrifugal pump, since the liquid enters the impeller under low pressure and flows out under high pressure, the pressure on both sides of the impeller is unequal, resulting in an axial thrust directed towards the inlet. It will cause axial movement of the rotor, resulting in wear and vibration, so an axial thrust bearing should be installed to balance the axial force.

As the name suggests, the Slurry Pumps are for pumping materials. The key to slurry pump success is the generation of centrifugal force, which pushes material outward from the pump center.

Heavy Duty Slurry Pumps can withstand extensive wear due to characteristics such as a large impeller diameter, shafts, bearings, and internal passageways as well as heavy-duty construction. On an industrial level, slurry pump features generate higher upfront and operational costs compared to water pumps. However, only slurry pumps can hydro transport solid materials efficiently, and the long-term benefits outweigh the initial costs.

According to different usage scenarios, the slurry pump can be divided into three types:

Wet — In this installation, the slurry pump and drive are fully submersible. This is necessary for certain slurry pump applications, such as underwater operations.

Dry — In this installation, the pump drive and bearings are kept out of the slurry. The wet end — which includes the shell, impeller, hub or suction liner, and shaft sleeve or stuffing box — is free-standing and clear of any surrounding liquid. Slurry pump technicians install most horizontal pumps this way.

Semi-dry — This special arrangement is used for dredging applications with horizontal pumps. Operators flood the wet end and bearings but keep the drive dry. Bearings require special sealing arrangements in this case.
