4.1 Mechanical functions
The metering pumps ELADOS

EMP III are membrane metering pumps driven by an electrical
motor for industrial use.
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 eccentric screw drive (pos. 1) moves the membranes (pos. 5) and thus transports the
metering material via the pressure valve (pos. 2). The suction valve is closed.
The membrane is moved back using a return spring (pos. 6), by means of which the metering
material is sucked into the pump head via the suction valve (pos. 3). The pressure valve is
closed.
The transported material can only be regulated via the stroke regulator (pos. 4) in 2 % steps
during operation. Here the return movement of the membranes is restricted.

WARNING
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).
The permissible primary pressure must always be adhered to in accordance with the table
(see chapter 11.3 “Technical Specifications “Overview tables””).
