is designed for continuously handing the most difficult higher abrasive slurries which contain too big solids. The gravel pump is casted as a single pump casing structure with smooth over-current channel .The overflow part is made of hard nickel and high chromium wear resistant alloy. The outlet direction of Sand Gravel Pump can be adjusted according to the request direction. The Sand Gravel Pump is suitable for delivering strong abrasive slurry containing bigger particles in mining, explosive sludge in metal melting, dredging and so on. The advantages of the Sand Gravel Pump are heavy flow, easy installation and operation, good performance of NPSH and abrasion resistance.

1. The heavy duty Sand Gravel Pump is horizontal, single pump casing structure centrifugal pump.

2. Use special clamp clamping pump body and pump cover, the pump outlet can be adjusted in the any direction of 360 degrees, easy to install and use.

3. The bearing components with cylindrical structure, easy to adjust the gap between the impeller and the pump body to keep long working life .

4. Bearing with grease lubrication.

5.The Sand Gravel Pump has three kinds of shaft seal including packing seal, vice impeller seal, mechanical seal.

6. Wide flow channel , good cavitation performance, high efficiency, abrasion resistance.

7.Transmission methods are: V-shaped V-belt driven, flexible coupling driven, gearbox transmission, hydraulic coupling driven, thyristor speed control speed and so on.

8.Over-flow components Material: nickel-containing high-chromium wear-resistant alloy.

9.Using variety speed and variants, making the pump running in the best conditions .

10. Long working life and high operating efficiency can meet a variety of bad working conditions .

sand dredge pumping , dredge river, mining and transport metal smelting .Flow range: 36-3800 m 3 / h Head range: 3.5-80 m. Maximum through particle size: 254 mm .Maximum efficiency: 72% Cavitation allowance: 2-8 NPSH (r).

Zhejiang customers signed a dry land dredging project. The required transport distance is 1500 m -2000 m, and the soil contains stones, garbage, etc. Required pump-type has to be easy construction, with good passage capacity and long service life. Which also can pump sand 300 m3/h, with diesel engine as power.

According to the customer’s construction requirements and the similar construction design experience. We recommended that customer choose the gravel suction pump ZS300-50 operation. And supporting the high pressure water pump,which to provide high-pressure water to impact the soil layer to form the slurry supply for the heavy duty Sand Gravel Pump .

Gravel pump ZS300-50 parameters

Heavy duty gravel pump flow channel is wide. And it’s good passage performance. And with wearable alloy material of pump shell, impeller and safe guard, so the Sand Gravel Pump has long service life. After inspecting the pump construction site, checking our parts, pumps, and comparing our proposal with Sand Gravel Pump from other supplier.The customer selected our Sand Gravel Pump . After we shipped Sand Gravel Pump ZS300-50 units to the customer’s site.The customer immediately installed the heavy duty Sand Gravel Pump in the existing floating platform.

Then they began trial production. During the first trial production day, the mud production is 500 m3. But there are diesel smoking and litter problem.After the customer reflected the problem, our company immediately contacted with the construction workers. Then we found the customer failed to install the long-distance pipeline at the outlet of the Sand Gravel Pump during the trial production.

There’s no demand for the gravel pump in actual head.So the pump flow rate increased, resulting in power demand exceeds of the diesel engine power.So then appeared black smoke, litter. We suggested customers to install the pipeline as soon as possible. The customer arranged immediately, and test the Sand Gravel Pump after the pipeline was installed. The failure before did not appear again. And the flow is 350 m3 when delivering 1,500 meters. Our customer is very satisfied with this.
