Slurry Pumps
For the transportation of liquids that have a high level of contamination, it is advisable to buy a slurry pump - a specially adapted equipment of the centrifugal principle of operation. Such units can effectively perform pumping work:
- sand from the bottom of rivers for construction and industrial use;
- rainwater and supply water from mines and quarries;
- water contaminated with small stones, industrial waste and other technological impurities;
- impurities of alumina production;
- high concentration flushing solutions;
- household sewage and other contaminated liquids.
Design features
Slurry pumping equipment is equipped with the following structural units and mechanisms:
- body;
- impeller equipped with rotating blades;
- electric motor;
- powerful rotor with an increased diameter;
- armored disc;
- a stator, in which the wall thickness is thinner than in pumps of other liquid designs;
- additional cooling system (in vertical and horizontal modifications) to prevent overheating.
The main working units are made of heavy metals with a chromium content of up to 28%. A rubber coating can be applied on top, which increases the life of the model.
Slurry Pump Classification
Depending on the design, slurry pumps for pumping dirty water are of horizontal, vertical and submersible type.
Horizontal modifications are installed outside the slurry tank. These are dry-type devices designed to capture solid particles in a mixture of a transported liquid. It is rational to use them for pumping hydraulic mixture, with the presence of solid ingredients up to 20 mm and with temperatures up to +50°C. Contaminated liquids with a density of 2500 kg/m³ are optimally captured through the inlet. Horizontal pumps are available in a wide range of capacities and pressures.
Vertical modifications pump liquids, in the total volume of which there is no more than 20% of contaminants. Limiting density of capturing liquids – no more than 1300 kg/m³. Such devices are also designed for dry installation, but unlike horizontal models, they exclude the formation of air pockets, which can cause a temporary stop in work.
Submersible modifications are used in places where direct contact with the pumped liquid is required, it is necessary to regulate the area and spatial positions of movement. During their work, a cable is often used to ensure the movement of the pump to the place of pumping. With the help of a cable, the pump is gradually immersed in the sludge as it is removed to the required depth. Thick slurry naturally enters the impeller of the unit and is pumped further. Descent level adjustment is determined visually. Due to the fact that the unit is immersed in liquid, noiseless operation is ensured.
Submersible pumps are designed to operate in difficult conditions. They are made of special wear-resistant alloys that are resistant to abrasive influences. Compared with horizontal and vertical models, the submersible slurry pump has an effective degree of protection against overheating, thanks to passive automatic cooling by the working mixture. We have pumps useful for meticulous cleaning of sewers, silted rivers, lakes, drain pits and other contaminated containers and reservoirs. They help to solve a wide range of tasks for pumping contaminated water in the construction and industrial industries, utilities, as well as for fire fighting.
