PP Pneumatic Diaphragm Pump

The pneumatic diaphragm pump is provided with the sample and highly reliable air reversing valve that makes the full series of diaphragm pumps realize the maximum reliability under various service conditions.
The reversing valve is the three-way pilot valve that can ensure no "sticky" in a real sense. All parts can be replaced without the need of opening the liquid cavity. The aluminum parts have been subjected to anodic oxidation treatment and coated with epoxy coated with epoxy coatings to resist corrosion caused by dirty air.
