Powerful Chemical Diaphragm Pump / Petrochemistry Low Flow Diaphragm Pump

Powerful Chemical Diaphragm Pump / Petrochemistry Low Flow Diaphragm Pump
 
Chemical Diaphragm Pump not only can exhaust the flow liquid , but also can convey some uneasy flowed medium.

• it’s unnecessary to pour the drawing water. The suction lift reached 7MM height, the delivery lift reaches 70M length and export pressure ***
• wide flow and good performance ,the diameter allowed pass the max grain reaches 10MM ,the damage is very less to the pump while exhausting the slurry and impurity.
• The delivery lift and flow can pass the pneumatic value open to realize the stepless adjustment.
• This pump has no rotary parts and no bearing seals, the diaphragm will completely separate the exhausted medium and pump running pollution and human body safety dangerous while exhausting the toxin and flammable or corrosive medium.
• No electricity , it’s safe and reliable while using in the flammable and explore places.
• It can be soaked in medium.
• It’s convenient to use and reliable to work . only open or close the gas value 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 over-loading ,the pump will automatically stop and possesses the self protection function, When the load recovers normally , it also can star automatically.
• 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 value and coupling lever etc. gear and vane etc.
• It can transmit the adhesive liquid (the viscosity is below 1000 centipoise ).
• This pump needn’t the oil lubricant, Even if idling ,it has influence to the pump, this is a characteristic of this pump.

Chemical Diaphragm Pump Parameters

 
Chemical Diaphragm Pump Main Advantages
1, Due to the use of air power, the flow automatically changed according to export resistance. Which is suitable for high viscosity fluid.
2, In inflammable and explosive environment, the pump is reliable and low cost, won't produce spark and not overheat,
3, The pump volume is small, easy to move, no foundation needed, convenient installation and economy. Can be used as mobile conveying pump.
4, Where there are dangers, corrosive materials processing, diaphragm pump can be separated completely with outside.
5, The pump shearing force is low, physical effect to medium is small, can be used for conveying unstable chemistry fluid.
 
Air Diaphragm Pump Application
 
It is widely applied in waste water treatment, chemical industry, petrochemical
industry, painting, ceramics, environmental protection, printing and dyeing, etc. to deal with all kinds of
corrosive, volatile, flammable, poisonous fluids with particles and high viscosity.
