Wear-resistant Rubber Slurry Pump

Driven by motor, the pump body and inlet line are filled with liquid before starting the pump. With high-speed rotation, the impeller drives the liquid between the vanes to rotate together. Due to the effect of centrifugal force, the liquid is thrown to the outer edge of impeller from the impeller center with kinetic energy increased. After the liquid entering the pump shell, as the flow channel in the volute type pump shell is gradually enlarged, the liquid velocity is decreased gradually, which makes part of the kinetic energy transform into static energy, therefore the liquid with high pressure is discharged along the outlet. At the same time, the impeller center forms a certain vacuum for th at the liquid is thrown out. The pressure on liquid level is higher than that of impeller center, so the liquid in suction pipe will flow into the pump under the action of pressure difference. With the constant rotation of impeller, the liquid is sucked and extruded continuously.


Based on the outstanding wear resistance of rubber and the molded rubber flow parts, Aipu wear-resistant rubber lined pump has absolute authority in terms of wear resistance. It has the features of smooth operation, energy convervation, low noise, cost saving, high efficiency, easy maintenance, and durability. The maximum concentration of pulp delivery should be no more than 60% (weightometer). The temperature of pulp delivery is among – 40 – + 70℃.


Our rubber pump is suitable for handling corrosive slurry or fluid containing solid materials, exceeding the scope of application of metal and other types of pumps. Beneficiation-metallurgy plant: Hydrocyclone feeding in grinding ore cycle (including the first stage of grading hydrocyclone); pump delivery, concentration & filtering of tailings, concentrates and intermediate products; all kinds of slurry pump delivery. Power plant: The delivery of tail ash, slag and coal slurry.

Sand and gravel plant: Sand and gravel transportation, sand and water supply of mining, all kinds of classification and dewatering equipment with remarkable wear resistance by contrast.

Coal preparation plant: Grading, screening and conveying of dense medium; coal slurry transportation. Chemical plant: The treatments of chemical liquid, acid or base, slurry, and waste water at low and medium temperature.

Water conservancy project: Damming, bed silt displacement, sand and gravel classification, etc.

Paper mill: The treatments of clay slip, paper pulp and waste water. Ceramic and glass plant: porcelain clay and sand & gravel transportation, hydrocyclones feeding and waste water treatment. Steel Plant: The delivery of slurry, Oxide skin, and corrosive liquid. Special instructions should be offered to us if with oil and chemical.
