What are the accessories of pneumatic diaphragm pump?

Shock absorber, flowmeter, oil-water separator and grease. The shock absorber automatically adjusts the air to compensate for the fluctuation of fluid pressure, without operator intervention, reducing large pulsation. The oil-water separator is used to filter the air source where the pump runs, and to filter out the water and impurities in the air, so that the diaphragm pump can work in a cleaner environment and greatly improve its service life. Grease is used inside the valve core to form a protective layer on the surface of the valve core, which is a trinity.
