Horizontal Centrifugal Gravel And Sand Pump,Dredge Pump

Product Overview-NNT Pump                                             

------ Features
1. It uses modern CAD design method, and has excellent hydraulic performance, high efficiency, and low wear rate;

2. It has wide runner, good anti-clogging performance, and excellent cavitation performance;

3. It uses expeller and filler combined seal and mechanical seal, ensuring that the slurry doesn't leak;

4. The reliability design greatly improves mean time between failures (MTBF) of complete machine;

5. It uses thin oil lubrication metric bearing, and rationally sets lubrication and cooling system to ensure that the bearing operates at low temperature;

6. Flow passage components are made of special materials, so they have good wear resistance and corrosive resistance; after special processing, they are used for seawater dusting, and seawater and salt mist electrochemical corrosion conditions;

7. In allowable pressure range, it can be used in series in stages, and allowable maximum working pressure is 3.6Mpa.

Pump Applications-NNT Pump                                                 

1, Gravel pumps are designed for continuously handling the most difficult higher abrasive slurries which contain too big solids to be pumped by a common pump.

2, Dredging, suck gravel in the dredger,  suck gravel in the course of rivers
3, Delivering slurries in mining, explosive sludge in metal smelting
4, Type GH pumps are of high-head ones
