Cast Iron Pneumatic Diaphragm Pump

Cast iron pneumatic diaphragm pump is a new type of conveying machinery, is a new type of pump in China. Using compressed air as the power source, no electronic components, for explosion-proof requirements of the working conditions of high safety, there is no impeller type of rotating parts in the pump, relying on the reciprocating motion of the diaphragm to achieve the suction of the medium. No leakage can be achieved in the work, and all kinds of liquids with particles, high viscosity, volatile, flammable and highly toxic liquids can be pumped out. The pump body is made of cast iron material, the overall cost is relatively low, and the cost performance is higher when transporting some non-corrosive media. Since the production, has been used by a variety of domestic petroleum, chemical, electronic, pottery textile system units, placed in special occasions, used to pump a variety of conventional pump can not be pumped media, have obtained satisfactory results.

1. Do not need irrigation water, suction up to 7m, head up to 50m, outlet pressure ≥6kgf/cm2;

2. The flow is spacious, through the performance is good, allow through the particle diameter of 10mm. When pumping mud and impurities, little wear to the pump, no need to lubricate with oil, even if idling, no impact on the pump;

3. The head and flow can be adjusted stepless through the valve opening (air pressure adjustment between 1-7kgf/cm2);

4. No rotating parts, no shaft seal, the diaphragm will pump the medium and the moving parts of the pump, the working medium * separated, the conveyed medium will not leak outwards. Therefore, when pumping toxic, easy to play or corrosive media, it will not cause environmental pollution and harm personal safety, and it can transport more viscous liquid (viscosity below 10,000 cm);

5. No need for electricity, safe and reliable in flammable and explosive places, can be immersed in the medium to work.

6. The function is convenient, reliable, open and stop simply open and close the gas valve, even if due to unexpected circumstances for a long time without medium operation or sudden stop, the pump will not be damaged, once overload, the pump will automatically stop, with self-protection performance, when the load returns to normal, and can automatically start operation;

7. Simple structure, less wearing parts, the pneumatic diaphragm pump has a simple structure, easy installation and maintenance, the pump transport medium will not contact the valve, rod and other moving parts, unlike other types of pumps due to rotor, piston, gear, blade and other parts wear and performance gradually decline.

1. Absorb all kinds of sewage, all kinds of rubber pulp, all kinds of high temperature liquid can withstand 150℃.

2. Can transport a variety of highly toxic, flammable, volatile liquid, a variety of strong acid, strong alkali, strong corrosive liquid.

3. Suck peanut butter, pickles, mashed potatoes, small sausage, jam apple pulp, chocolate, hops and baking powder dilute pulp, syrup, sugar dense, etc.

4. All kinds of abrasives, etchant, oil and mud, cleaning oil scale and general containers, suction mine, tunnel, mineral processing, slag in the water.

5. Paint, gum, pigments, adhesives and glues, all kinds of tile, porcelain, brick and pottery glaze and all kinds of emulsions and fillers, cement grouting and mortar.

6. After drilling the oil well, pump the sediment and grouting, and absorb the sewage in the silo for the tanker and barge clearance, which can be used as the pre-stage pressure feeding device for various solid and liquid separation equipment.
