Pneumatic Diaphragm Pump QBY Series 
QBY AODD Pump
Pneumatic Diaphragm Pump Advantage:
(1) QBY aodd pump will not overheat: compressed air for power. Exhaust is an expansion heat absorption process, pneumatic pump working temperature is reduced. No harmful gas emissions.
(2) Will not produce electric sparks: pneumatic diaphragm pump does not use electricity as power, grounding and prevent electrostatic sparks
(3) It can pass through granular liquid: it is not easy to be blocked because of positive displacement operation and the inlet is a ball valve.
(4) Shear force of the material is very low: how to suck in and how to spit out when working, so the agitation of the material is minimal, suitable for the transport of unstable material
(5) flow can be adjusted. Throttle valve can be installed at the outlet of materials to regulate the flow.
(6) It has the function of self-absorption.
(7) Run empty without risk.
(8) Work underwater.
(9) Transport a wide range of fluids, from low viscosity to high viscosity, from corrosion to viscous.
(10) no complicated control system, no cables, fuses, etc.
(11) small size, light weight, easy to move.
(12) No lubrication is needed. So the maintenance is easy, and the working environment will not be polluted by drip leakage.
(13) Pump is always efficient and will not be reduced by wear.
(14) When the outlet is closed, the pump automatically stops. Equipment movement, wear, overload, heat.
