Sandpiper pneumatic diaphragm pump is a pump that uses a diaphragm to transport the pumped solution (pump substance) by the action of a pneumatic diaphragm. Then use the pressure of compressed air to act on the pump diaphragm and transfer this pressure to the pump substance. Then the pump is in the compressed air chamber to fill the pump. The suction and ejection of the diaphragm pump also relies on the action of the one-way ball valve. The application of pneumatic diaphragm pumps in production will help businesses make the most of human resources in other activities, avoiding direct contact with harmful substances.
