Pneumatic Diaphragm Pump
Depamu is a diaphragm pump manufacturing specialist in China. Our DPQ series pneumatic diaphragm pump is the product of choice for various chemical dosing applications in petroleum processing, chemical engineering, electronics, ceramics, and textile industries where special media are involved that cannot be handled with conventional pumps.
The Depamu pneumatic diaphragm pump uses compressed air to drive diaphragms flexing back and forth, causing suction and discharging of process fluid. DPQ series products are spark proof, safe, reliable, and cost effective.
Features of Pneumatic Diaphragm Pump
1. Compressed air is used as the power source for this diaphragm metering pump, which makes it suitable for use in flammable or explosive environments.
2. The straight-through path allows process liquid to pass smoothly. Maximum allowable diameter of solid particles contained in the liquid is up to 10mm.
3. DPQ series pneumatic diaphragm pump is one of your best choices for pumping corrosive, volatile, flammable, toxic, or viscous liquids with viscosity no more than 10,000cP.
4. We offer pneumatic diaphragm pumps in engineering plastics, aluminum alloy, cast iron, and stainless steel.
