Gravel Pump For Sale

Sand And Gravel Pumps series of Sand And Gravel Pumps is designed specifically for continous pumping of extremely aggressive slurries, with a wide particle size distribution. Capable of handling large particles at consistently high efficiencies results in low cost of ownership. The large volume internal profile of the casing reduces associated velocities further increasing component life.Sand And Gravel Pumps are long life, efficient operation and easy maintenance.Besides,Sand And Gravel Pumps have high-chrome wet ends with expeller or stuffing box seal arrangements.It is mainly used for long distance delivery with thicker wall in more durable working life and higher efficiency.

Chongmu Fluid Machine Sand And Gravel Pumps are the most comprehensive range of centrifugal gravel sand pumps for use in mining, chemical and general industry applications. The horizontal sand gravel pumps are designed for heavy duty applications such as mining, power sector,dredging river,and tailings as well as specialty applications, which are used for continuous pumping of high abrasive, high density sand and gravels.

Characteristics of Sand And Gravel Pumps

1. This series of Sand And Gravel Pumps are horizontal centrifugal pumps with a single pump shell structure.Broadly speaking, it also belongs to a kind of slurry pump.

2. The Sand And Gravel Pumps body and pump cover are clamped by special clamps, and the outlet direction of the pump can be at any position of 360 degrees, which is easy to install and use.

3. The bearing assembly of the Sand And Gravel Pumps adopts a cylindrical structure, which is convenient to adjust the gap between the impeller and the pump body, and can be removed as a whole during maintenance.

4. The bearings are lubricated with grease.

5. There are three types of shaft seals for Sand And Gravel Pumps: packing seal, expeller seal, and mechanical seal.

6. The Sand And Gravel Pumps has a wide flow path, good cavitation performance, high efficiency and abrasion resistance.

7. The main transmission methods are: V-belt transmission, elastic coupling transmission, Gear reducer transmission, SCR speed control, etc.

8. Material of Wet parts: nickel-containing high-chromium wear-resistant alloy.

9. The use of multiple speeds and multiple variants makes the pump run under the best conditions.

10. Long service life, high operating efficiency, and can meet many types of harsh transportation conditions.

11. Applicable to: dredger for sand dredging, river dredging, mining and metal smelting explosion slag transportation.

Sand And Gravel Pumps Design Considerations

Bearing assembly and shaft

1. The shaft is designed with a short overhang to:

- Reduce shaft deflection

- Minimise vibration

2. Provided with hardened shaft sleeve to protect the shaft

3. Bearing assembly is retained on a one piece frame

4. Grease-purged piston rings to help seal contaminates out of bearing housing

Impeller

1. Enclosed impellers to maximise efficiency

2. High chrome wet parts

3. Interchangeable hard metal impellers

4. Impeller clearance is set by moving the bearing assembly

5. High efficiency impeller optional

Single pump casing with assembly clamps

1. Easy assembly and disassembly of wet parts

2. Clamp design facilitates rotation of volute

3. Large volute reduces friction and wear

4. Minimal parts + simple design

Structure Of Sand And Gravel Pumps:

Sand and gravel can be pumped as slurry, when mixed with water to allow the fluid to carry the suspended particles along pipework infrastructure. Sand pumps, sand and gravel pumps, or gravel pumps are all synonymous with slurry pumps. The suspended particles act as an abrasive, so care must be taken to install appropriate abrasive resistant piping and pumps for applications requiring the movement of suspended sand and/or gravel. ChongMu’s Horizontal Slurry Pump series of slurry pumps are the best choice for moving sand and gravel. Available with internal parts that are composed of special hardened alloys or coated with rubber like elastomers to prevent abrasion of key components, these pumps are ideal for dewatering applications where sand and/or gravel are involved.

series Sand And Gravel Pumps are horizontal single-casing slurry pumps with wide passage to transfer sand or slurry with big particle size. The wet parts are made of Ni-hard and high-Chrome alloys to ensure long service life. Sand And Gravel Pumps have far better performance than common pumps in dredging, sand mining, barge loading and mineral processing, etc. Featured with all the advantages of Horizontal Slurry Pump series gravel pumps have achieved extra high head for special working conditions.ChongMu Fluid Sand And Gravel Pumps are designed for continuously handling the most difficult higher abrasive slurries which contain too big solids to be pumped by a common slurry pump. ChongMu Fluid Sand And Gravel Pumps are horizontal centrifugal pumps with a single pump shell structure. Broadly speaking, it also belongs to a kind of slurry pump.
