As
the name suggests, Diaphragm Metering Pump using a special design and
processing of flexible diaphragm instead of the piston, under the action
of the drive mechanism to achieve reciprocating motion, complete the
suction - discharge process. Due
to the segregation of the diaphragm, the isolation between the metering
fluid and the driving lubrication mechanism is realized in the
structure. High-tech structural design and the selection of new materials has
greatly improved the service life of the diaphragm, coupled with
excellent corrosion resistance of composite materials, diaphragm
metering pumps become the main application of fluid measurement pump
type.
