4.1 Mechanical functions
The metering pumps ELADOS ® EMP KKS are diaphragm-piston metering pumps driven
by an electrical motor only suitable for use in commercial ranges.
The membranes are for the pre-delivery, the piston is for the metering. Because of the
permanent overpuls refeeding this metering pump works self venting.
The metering pumps are suitable for use with clean, non-abrasive metering media with a
viscosity of up to 200 mPas (measuring manner: Brookfield).
The metering pump is operated by a non-blocking synchronous motor and a connecting
rod-eccenter gear.
Fig. 2: Mechanical functions
When the diaphragms (pos. 1) moves towards the gear, the valve (pos. 2) suck up the
metering product.
Simultaneously, vacuum grow out of the compression chamber of the metering piston
cylinder unit (pos. 3). When the inspection hole (pos. 4) has been released,
the pre-delivered metering product flows into this chamber.
During the pressure motion metering happens over the valve (pos. 5); the surplus product
get returned into the container by the return valve (pos. 6).
The stroke adjustment (pos. 7) regulates the volume delivered during the operation from
0 - 100 %. This changes the immersion depth of the cylinder.
The pre-delivered amount keeps constant.
NOTICE!
To protect the metering device, the use of a suction pipe with an empty
reporting device and dirt arrestor (available from our range of accessories) is
highly recommended!
The empty reporting device switches off the pump if it falls below a certain level
(in the container).
