Marine Diaphragm Pump

Product description:

Pneumatic diaphragm pump is a new type of conveying machinery, which uses compressed air as the power source. It can efficiently pump various corrosive liquids, liquids with particles, high-viscosity, volatile, flammable, and highly toxic liquids. Suck. The main feature of this kind of pump is that it does not need to irrigate and divert water, it can not only pump flowing liquid, but also convey some easy-flowing media, with high suction lift and adjustable lift (0-50 meters). cm2 can work, absolutely fireproof and explosion-proof, with all the functions of submersible pump, self-priming pump, impurity pump, shield pump, mud pump and many characteristics of conveying machinery. It is currently one of the most innovative pumps in the world.

Pneumatic diaphragm pumps are available in four materials: plastic, aluminum alloy, cast iron, and stainless steel. Diaphragm pumps use nitrile rubber, neoprene rubber, fluorine rubber, polytetrafluoroethylene and polytetrahexaethylene respectively according to different liquid media. to meet the needs of different users. It has been installed in various special occasions and used to pump media that cannot be pumped by conventional pumps, and all have achieved satisfactory results.

Features

1. No need to irrigate and divert water, the suction lift is up to 7m, the lift is up to 50m, and the outlet pressure is ≥6kgf/cm2;

2. The flow is spacious, the passing performance is good, and the maximum particle diameter allowed to pass is 10mm. When pumping mud and impurities, the pump wears very little;

3. The lift and flow can be adjusted steplessly through the opening of the air valve (the air pressure is adjusted between 1-7kgf/cm2);

4. The pump has no rotating parts and no shaft seal. The diaphragm completely separates the pumped medium from the moving parts and working medium of the pump, and the conveyed medium will not leak to the outside. Therefore, when pumping toxic, easy-to-play or corrosive media, it will not cause environmental pollution and endanger personal safety;

5. There is no need to use electricity, and it is safe and reliable to use in flammable and explosive places;

6. Can be immersed in the medium to work;

7. The function is convenient and the work is reliable. It only needs to simply open and close the gas valve to start and stop. Even if there is no medium running for a long time or sudden shutdown due to unexpected situations, the pump will not be damaged. Ground shutdown, with self-protection performance, when the load returns to normal, it will automatically start running again;

8. The structure is simple and the wearing parts are few. The pump has a simple structure and is easy to install and maintain. The medium conveyed by the pump will not contact the moving parts such as the gas distribution valve and the connecting rod, unlike other types of pumps due to the rotor, piston, gear , The wear of the blades and other components will gradually reduce the performance;

9. It can transport viscous liquid (viscosity below 10,000 centipoise);

10. The pump does not need to be lubricated with oil, even if it is idling, it has no effect on the pump

The main purpose:

1. All kinds of strong acid, strong alkali and strong corrosive liquid.

2. Pump paint, gum and pigment.

3. Adhesives and glues, all types can be pumped up.

4. All kinds of tile, porcelain, brickware and pottery glaze paste.

5. After the oil well is drilled, pump the sediment and grouting.

6. Pump various emulsions and fillers.

7. Pump all kinds of sewage.

8. Use the pump for the tanker and the barge to clear the warehouse to absorb the sewage in the warehouse.

9. Hops and baking powder slurry, syrup, sugar density.

10. Pumping water in mines, tunnels, tunnels, beneficiation and slag. Pumping cement grouting and mortar.

11. All kinds of rubber pulp.

12. Various abrasives, corrosives, petroleum and mud, cleaning grease and general containers.

13. Various highly toxic, flammable and volatile liquids.

14. Pump peanut butter, pickles, mashed potatoes, red sausage, jam apple pulp, chocolate, etc.

15. Various high temperature liquids can withstand up to 150 ℃.

16. As the front-stage pressure feeding device of various solid-liquid separation equipment.
