5I DELLMECO I EODD DIAPHRAGM PUMPS
1. Introduction
DELLMECO DME (Electro-Mechanical Operated Double Diaphragm Pump) is a positive-displacement pump that
transfers fluids by means of diaphragms operated by linear mechanism, which is being moved by electric motor. The casing
in contact with the fluid is made of PE conductive (R
…), PTFE conductive (Z…), Aluminium (A..), AISI 316 (S..), Cast Iron
(C..), or AISI 316L (H.., Hygienic Stainless Steel). This pump is designed for the pumping of liquids, highly viscous and
solid substance-containing media, as well as fluidizable powders.
DELLMECO DME Pumps consist of two pump housings located opposite each other. The diaphragms that separate
drive and liquid areas from side housings, include a built-in metal core which ensures an optimum service life of
diaphragm.
A linear drive, located between pump housings, converts the rotating motion of the drive machine into oscillating one
through a crank. The directly linked diaphragms are moving there and back with a constant stroke, and they never
undergo a tipping motion due to special design. With each revolution of the crank the medium contained in the pump
housing is alternatively pumped out of the housing and sucked into the opposite pump housing. When the upward motion
switches to discharge motion and vice versa, the other housing assumes the suction or discharge function. Every pump
housing has ball valves or cylindrical valves (available for DME Plastic Pumps only) on the suction and discharge sides.
These valves work independently and are available in various versions, which makes it possible to optimize the shearing
and solid substance non-sensitivity, as well as to select valve material with chemically required properties depending on
the medium.
2. For safe operation
