Working principle

• The principle feature of this series of products is a mechanical diaphragm metering pump driven by a motor through a worm gear, suitable for fluid metering in low-pressure applications.
• The diaphragm metering pump can completely isolate the overcurrent liquid from the driving lubrication mechanism using a diaphragm, and the pump adopts a high-tech structural design.
• Diaphragm metering pumps can be adjusted infinitely within the range of 0-100% according to the needs of various process flows, and can quantitatively transport corrosive and non corrosive liquids without solid particles.
• The diaphragm metering pump uses a flexible diaphragm instead of a piston, which is driven by the driving mechanism to make the diaphragm move back and forth, changing the pump chamber volume and sucking and discharging liquid under the action of the pump inlet and outlet valves.
