What Are the Types of Slurry Pumps?

Slurry pump is a centrifugal pump with high efficiency and relatively strong performance that has evolved in recent years due to the large material transport particles. Conceptually, a slurry pump refers to a device that converts electrical energy into kinetic energy and potential energy of a medium by increasing the energy of the solid and liquid mixed medium by the action of centrifugal force (the rotation of the impeller of the pump). It is mainly used in mining, power plant, dredging, metallurgy, chemical industry, building materials and petroleum industries.

Slurry pumps generally refer to pumps suitable for conveying liquid (water) containing suspended solids as slurry pumps. At present, it is one of the indispensable equipments in each technological process of beneficiation and coal preparation plants. Slurry pumps can be divided into single-stage / multi-stage, single-suction / double-suction, cantilever, horizontal / vertical, and horizontal / open / vertical combination of pump casing according to different principles. It is composed of shaft, bearing and bracket. The power also includes motor, counter-wheel or belt-wheel coupling, etc., wear-resistant parts also include liner bushings, etc., seals include shaft seal, auxiliary impeller, etc., support parts include brackets, etc. However, the internal principle is the same. When the impeller rotates quickly, the blades cause the medium to rotate quickly. The rotating medium flies out of the impeller under the action of centrifugal force. After the medium in the pump is thrown out, the center of the impeller forms a vacuum In the area, the medium is pressed into the feed pipe through the pipe network under the action of atmospheric pressure (or water pressure). In this way, continuous feeding can achieve continuous feeding, so as to achieve the head and flow required by the process design. Of course, the feeding method currently uses the press-in type, that is, the material level is higher than the feeding pipe, and the step of pouring water from the upper water pipe or the pump casing into the interior can be subtracted.

【ZJ / ZJL Series Slurry Pump】

The types of ZJ series slurry pumps are divided into two categories, one is the ZJ type, which is a horizontal axial suction single stage single suction centrifugal slurry pump; the other is the ZJL type, which is a vertical axial suction single suction centrifugal pump Slurry pump. The pump shaft and motor of this series of slurry pump can be directly driven by a coupling or driven by a belt.

ZJ type pump has wide performance range, good cavitation performance and high efficiency. Multi-level series technology can be used to meet long-distance transportation. A variety of metals are available for overcurrent parts, and the depth is increased. A variety of speeds and variants are used to make the pump run under the best industrial and mining conditions. It has a long service life and high operating efficiency, and can meet various harsh transport conditions.

ZJ type slurry pump has the characteristics of high efficiency, energy saving, low vibration, low noise, reliable operation, long service life and convenient maintenance. It can be widely used in power, metallurgy, coal, building materials and other industries to transport slurry containing solid particles. Such as thermal power plant hydraulic ash removal, metallurgical beneficiation plant slurry transport, coal washing plant coal slurry and heavy medium transport, etc.

【M, AH HH slurry pump】

 M, AH, HH type pump cantilever, horizontal slurry pump. It is suitable for conveying strong abrasive and high-concentration slurry in metallurgy, mining, coal building materials and other industrial sectors. This type of pump can also be used in multiple stages in series. The pump body of M and AH pumps has replaceable wear-resistant metal or rubber, and the impeller is also made of wear-resistant metal or rubber. Among AH slurry pumps, AH means heavy duty pump. The so-called heavy duty refers to the concentration of slurry. Generally, the slurry concentration is 0-15% for low concentration, 15% -30% for medium concentration, and more than 30% is generally called high concentration. Here ah slurry pump is for conveying slurry concentration. Generally, heavy-duty pumps require your light or neutral lining to be heavy, which increases wear resistance and extends the overall service life of the pump.

M, AH, HH pump shaft seals can use packing seals or centrifugal seals, and the pump's discharge outlet position can be installed at eight different angles at 45-degree intervals as required.

【ZJG slurry pump】

This type of slurry pump is used in mining, metallurgy, power, coal, chemical, building materials and other industries to transport abrasive and corrosive slurry containing solid particles. The maximum weight concentration of its solid-liquid mixture: mortar 45%, ore slurry 60% This series of slurry pumps have complete specifications, and can adopt direct transmission, belt, hydraulic, frequency conversion speed regulation and other transmission forms.

【ZGB / P slurry pump】

ZGB series slurry pumps are horizontal, single-stage, single suction, cantilever, double pump casing, centrifugal slurry pump. The overflow parts of ZGB and ZGBP slurry pumps of the same caliber can be interchanged. The installation dimensions are exactly the same. The transmission part of the ZGB series slurry pump adopts a horizontally open thin oil lubrication bracket, and is provided with two internal and external cooling systems. If necessary, add cooling water.

There are two types of shaft seals for ZGB series slurry pumps: combined seal with impeller and packing and mechanical seal. It is recommended to use a mechanical seal with high-pressure shaft seal water for series slurry pumps (level 2 or above). The single-stage or series-connected one adopts a combination impeller and packing seal.

The product use of this series of slurry pumps: after special treatment, it is used for seawater ash removal and electrochemical corrosion of seawater and salt spray; it can be used in multiple stages in series within the allowable pressure range, and its maximum allowable working pressure is 3.6MPa.

The products such as slurry pump, multistage pump, sewage pump are widely used in metallurgy, mining, petrochemical, coal, electricity and so on. Welcome to choose us!
