Heavy Duty Sand Pump For Cutter Suction Dredger

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.
