Plastic Diaphragm Pump
QBY pneumatic diaphragm pump is currently one of the most innovative pumps, simple structure, easy overhaul , sending liquid stable , vibration, low noise , self-absorption capacity , transmission fluid viscosity is high, with pump, submersible pumps , shielding pumps, mud pumps and impurities many advantages , such as transportation machinery . Using compressed air as a power source for a variety of corrosive liquid , with particles of high viscosity , volatile, flammable, poisonous liquid , easy -flowing liquid can be pumped exhaustion. The performance parameters and Federal Republic of Germany WLLDENPVMPS, and U.S. MARIOWPUMPS . Has been adopted by tens of thousands of domestic petroleum , chemical, food, medicine , electronics, ceramics , textiles, brewing, paper system unit , housed in a variety of special occasions , for pumping kinds of conventional pumps can not pump the media , have achieved satisfactory effect.
The diaphragm is the core component of a diaphragm pump , depending on the media , the choice of chloroprene rubber , PTFE rubber, nitrile rubber , etc., in order to meet the requirements of different users . Pump flow part , according to user requirements , selection of cast iron , aluminum , stainless steel and plastic of different materials .
» no irrigation water , suction lift up to 5 meters , lift up to 70 m , the outlet pressure ≧ 7bar;
» mobile spacious , good performance , allowing the maximum particle diameter of 10 mm . Pumping mud, impurity , minimal wear and tear on the pump ;
» head, flow stepless adjustment can be achieved through the valve opening degree ( pressure adjustment between the 1-7bar);
» the pump with no moving parts, no shaft seals , diaphragm pumps and other pumping medium with moving parts , completely separated from the working medium , the transmission medium does not leak out . So pumping toxic , volatile or corrosive media, will not cause environmental pollution and danger to personal safety ;
» do not have electricity, the use of safe and reliable in flammable and explosive places ;
» the work can be immersed in the medium ;
» easy to use , reliable, open to stop simply open and close the gas valve , even for a long time because of accident or sudden stop running no media will not result in damage to the pump , once the overload , the pump will automatically shut down , a self- protective properties , when the load back to normal, and can automatically start running ;
» simple structure, less wearing parts , the pump structure is simple to install , easy maintenance, medium conveyed by the pump does not come into contact with the valve , linkage and other moving parts , unlike other types of pumps due to the rotor , pistons , gears wear performance blades and other parts of leaving the gradual decline ;
» can transport more viscous liquid ( viscosity 10,000 cps or less ) ;
» the lubricating oil pump is not required , if idling , and no effect on the pump , which is a major feature of the pump .
