1.What is a Heavy Duty Slurry Pump? What are AH Heavy Duty Slurry Pumps used for?
The heavy duty slurry pump is known as the AH type pump. DEPUMP®AH heavy duty slurry pumps is a single stage single suction, cantilever, horizontal centrifugal slurry pump. This AH heavy duty slurry pumps has thick wear-bearing parts and is equipped with heavy-duty brackets, so it is suitable for conveying strong abrasive, high-concentration slurries or low-concentration and high-lift slurries. Within the maximum allowable working pressure range of the pump, it can be used in multiple stages in series. DEPUMP® AH heavy duty slurry pumps can also be used to transport corrosive slurry.
AH heavy duty slurry pumps is a horizontal, vertical split-type, double pump casing structure. The pump body and pump cover are equipped with replaceable metal lining or rubber lining, ceramic lining, and the impeller is made of wear-resistant metal or rubber material. Shaft seals can be packing seals, mechanical seals or centrifugal seals. The outlet position of the pump can be installed and used by rotating at eight different angles at intervals of 45°C as required.
AH heavy duty slurry pumps is a cantilever centrifugal slurry pump, suitable for conveying abrasive or corrosive slurry, and is widely used in metallurgy, mining, petroleum, chemical, coal, electric power, transportation, river dredging, building materials and municipal engineering, etc. department.
The bearing assembly of the pump adopts a barrel structure, which is convenient to adjust the gap between the impeller and the front guard plate, and can be disassembled as a whole during maintenance. Bearings are grease lubricated.
2.AH heavy duty slurry pumps structure
AH heavy duty slurry pumps belongs to the category of common slurry pumps. This series of pumps are horizontal, vertical, and double-shell structure slurry pumps. According to the pump head and size, it is divided into different models.DEPUMP®AH heavy duty slurry pumps consists of the following parts:
A. Pump head part
DEPUMP® AH heavy duty slurry pumps has a double pump casing structure, that is, the heavy duty slurry pump body and pump cover have replaceable wear-resistant metal linings (including impellers, sheaths, guard plates, etc.). The heavy duty slurry pump body and heavy duty slurry pump cover are made of gray cast iron or ductile iron according to the working pressure, open vertically and connected with bolts. The heavy duty slurry pump body has a stop and is connected with the bracket by bolts. The discharge port of the heavy duty slurry pump can be rotated and installed at eight angles. The front and rear cover plates of the impeller have back vanes to reduce leakage and increase the service life of the heavy duty slurry pump.
Pump body, pump cover and over current parts: DEPUMP® AH heavy duty slurry pumps body and pump cover are equipped with replaceable metal linings. The lining material is high-chromium wear-resistant alloy material. cost. The outlet direction of the heavy duty slurry pump can be rotated and installed at 8 angles.
Bearing assembly: The bearing assembly of the heavy duty slurry pump adopts a cylindrical structure, which is convenient to adjust the gap between the impeller and the front guard, and can be disassembled as a whole during maintenance. Bearings are grease lubricated.

B. Shaft seal part
AH Heavy duty slurry pumps shaft seals include auxiliary impeller shaft seals and packing shaft seals.
(1). Auxiliary impeller shaft seal: When the positive pressure value of DEPUMP® AH heavy duty slurry pumps inlet is not greater than 10% of the AH heavy duty slurry pumps outlet pressure value, the single-stage pump or the first-stage pump of multi-stage series series can use the auxiliary impeller shaft seal. The auxiliary impeller shaft seal has It does not need shaft sealing water, does not dilute the pulp, and has the advantages of good shaft sealing effect.
(2). Packing shaft seal: The packing shaft seal has a simple structure and is easy to maintain, but the shaft sealing water must be used. For the working conditions that are not suitable for the auxiliary impeller shaft seal, the packing shaft seal can be used.
(3). mechanical seal: double-end water injection type, single-end water-free type, water injection three structures.
C.Transmission partThere are V-shaped V-belt transmission, elastic coupling transmission, gear reduction box transmission, hydraulic coupling transmission, variable frequency drive device, Silicon controlled speed regulation, etc. Among them, the V-belt transmission includes CL, CV, CR, ZL, ZV, ZR transmission.All kinds of horizontal slurry pumps use the same series of transmission parts, including brackets and bearing assemblies. The pump shaft has a large diameter, good rigidity, short cantilever, and will not bend and vibrate in harsh working conditions. The bearing is based on the transmitted power. Different selections of heavy-duty single-row or double-row tapered roller bearings and cylindrical roller bearings can withstand the maximum axial and radial loads of DEPUMP® AH heavy duty slurry pumps. The bearings are lubricated with grease. Effectively prevent sludge and other dirt from entering the bearing, ensure the safe operation of the bearing, and have a high service life.
DEPUMP®MAH heavy duty slurry pumps has a wide performance range, good NPSH performance and high efficiency. In serial technology can be used to meet long-distance transportation. Wet parts are available in a variety of metals and with increased depth. A variety of speeds and variants are used to make the AH heavy duty slurry pumps run at the optimum mine. It has long service life and high operating efficiency, and can meet many kinds of harsh conveying conditions.

Horizontal slurry pumps mainly include Heavy Duty Slurry Pump, Centrifugal Slurry Pump, Slurry Pump for Mining, etc. If you want to know more, you can send us an email and we will get back to you soon.
MAH heavy duty slurry pumps are heavy duty horizontal slurry pumps designed to handle abrasive and high density slurries in mining and heavy industry.Horizontal slurry pumps are applied in various slurry transport applications. With wear parts in either hard metal or rubber, horizontal slurry pumps are often larger, more powerful and offer higher capacity than vertical slurry pumps.
Centrifugal Slurry pump refers to a kind of machinery that increases the energy of solid and liquid mixed media by means of centrifugal force (the rotation of the impeller of the pump), and converts electrical energy into the kinetic energy and potential energy of the medium. Mainly applicable to: mining, power plants, dredging, metallurgy, chemical industry, building materials and petroleum industries. The most common type of slurry pump is the centrifugal pump. These pumps use a rotating impeller to move the slurry, similar to how a water-like liquid would move through a standard centrifugal pump.
Metal Lined Heavy Duty Slurry Pump Slurry Pump for Mining Heavy Duty Sand Dredging Slurry Pump for Gold Mine Heavy Duty Horizontal Centrifugal Slurry Handling Pump.Slurry pumps are heavy duty, rugged centrifugal pumps designed to handle harsh and abrasive jobs. In mining and ore processing operations, mud pumps are an important means of efficiently transporting mud at any distance. Slurry pumps are modified in design and construction to accommodate many types of slurries that vary in solids concentration, solid particle size, solid particle shape and solution composition.
Electric Mining Slurry Pump is easy to adjust the space between the impeller and the front liner, which can be completely removed during maintenance.The working principle of a mud pump is relatively simple and easier to follow than other pumps. The mud enters the pump through a rotating impeller, which imparts a circular motion. The slurry is then pushed outward by centrifugal force and moves between the impeller blades.
