Product Description

Sand And Gravel Pumps


Horizontal Slurry Pump 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 ease of 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, hydraulic coupling 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

Features Of Sand And Gravel Pumps

1. Broad impeller path created by single casing and clamp bands connection;

2. Unique design to make maintenance and wet parts replacement convenient;

3. Dig deep advantage, good dig deep effect within 30 meters.

4.Use a variety of speed and modifications to make pump running under best condition. Long service life, high efficiency which can meet many poor transport conditions.

5. The discharge direction of pump can be oriented in any direction of 360°.

6. Driving type mainly have V belt drive, elastic coupling drive, gear reducer drive, hydraulic coupling drive, variable frequency driven etc.


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


1. Enclosed impellers to maximise efficiency

2. Pump-out vanes on both shrouds

- Minimises re-circulation

- Reduces stuffing box pressure

3. High chrome liquid ends

4. Interchangeable hard metal impellers

5. Impeller clearance is set by moving the bearing assembly

6. High efficiency impeller optional

Single casing with assembly clamps

1. Easy assembly and disassembly of liquid end

2. Clamp design facilitates rotation of volute

3. Large volute reduces friction and wear

4. Minimal parts + simple design

Centrifugal seal option

1. Reduces or eliminates need for gland service water

2. Reduces sleeve wear and possible bearing contamination

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. The Silver series is engineered with oversized components where heavy duty is not quite heavy enough. These pumps can handle super heavy-duty conditions. Designed with the same attention to detail, the Horizontal Slurry Pump series has the advantage of higher flow rates, topping out at 1400 litres per second. The silver series pumps are also available in vertical configurations. All of ChongMu’s sand and gravel pumps feature easy to change cartrtidge type bearing assemblies that are just one of the design features that make ChongMu’s pumps easy to use and maintain.

Horizontal Slurry Pump 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 pumps 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.If you are interested in our products,welcome to CONTACT US when you free.
