Overview:
This series of Diaphragm pumps are the latest model at home. They are functioned to take out and suck in various corrosive liquid containing granules, viscous, volatile, inflammable, explosive or poisonous liquid, porcelain slurry, mashed fruit, flue, the reclamation of residual oil in tanker, temporary reversion of tanker, etc. The performance parameters of this series are close to that of German WILLDENPUMPS and American MARIO-WPUMPS. The components in contact with flow are made of stainless steel, aluminium alloy, cast iron and engineering plastics, while diaphragm may be NBR, viton, neoprene or PTEE.
Usage:
1. The pump can suck the peanut, pickles, tomato, slurry, red sausage, chocolate, hops and syrup etc.
2. The pump can suck the paint, pigment, glue and adhesive etc.
3. The pump can suck various glazed slurries of tile, porcelain, brick and chinaware etc.
4. The pump can suck various grinding materials, corrosive agent and clean the oil dirty etc.
5. The pump can suck various toxin and flammable or volatility liquid etc.
6. The pump can suck various wedge water, cement slurry and mortar etc.
7. The pump can suck various strong acid, alkali and corrosive liquid etc.
8. It can be used as a front-step transmission device of the solid and liquid separation equipment.
Functions and Features:
QBY air operated double diaphragm pumps not only can exhaust the flow liquid, But also convey some uneasy flowed medium with the merits of self-pumping pump, Diving pump, Slurry pump and Impurity pump etc.
1. It’s unnecessary to pour the drawing water, the suction lift reaches 7m height. The delivery lift reaches 50m length and the export pressure ≥6kgf/cm2.
2. Wide flow and good performance. The diameter allowed to pass the max grain reaches 10mm. The damage is very less to the pump while exhausting the slurry and impurity.
3. The delivery life and flow can pass the pneumatic valve open to realize the steps adjustment(The pneumatic pressure adjustment is between 2-8kgf/cm2)
4. This pump has no rotary parts and no bearing seals. The diaphragm will completely separate the exhausted medium and pump running parts, working medium. The conveyed medium can’t be leaked outside. Thus it will not cause the environmental pollution and human body safety dangerous while exhausting the toxin and flammable or corrosive medium.
5. No electricity. It’s safe and reliable while using in the flammable and explore places.
6. It can be soaked in medium.
7. It’s convenient to use and reliable to work. Only open or close the gas valve body while starting or stopping. Even if no medium operation or pausing suddenly for long time because of accident matters, the pump will not be damaged caused by this. Once outer-loading. The pump will automatically stop and possesses the self protection function. When the load recovers normally. It also can start automatically.
8. Simple structure and less wearing parts. This pump is simple in structure, installation and maintenance. The medium conveyed by the pump will not touch the matched pneumatic valve and coupling lever etc. Not like other kinds pumps, the performance will drop down gradually because of the damages of rotor, gear and vane etc.
9. It can transmit the adhesive(the viscosity is below 10000 centipoise)
10. This pump needn’t the oil lubricant. Even if idling, It has any influence to the pump. This is a characteristic of this pump.
