WARNING
Use for intended purpose
•
The pump is designed as a liquid medium metering pump; it serves the purpose of
metering liquid medium within the specified line system!
•
Operate the pump only within the conditions described in the technical data!
•
General restrictions with regard to viscosity limits, chemical resistance and density must
be observed (refer to ProMinent
®
chemical resistance list (catalogue or homepage))!
•
All other applications or conversion are prohibited!
•
The pump is not designed to meter gaseous media as well as solids.
•
The pump is not suitable for metering combustible liquids!
•
Only specifically trained and authorized personnel are permitted to operate the pump!

Design/Functional description
2.2.1
Functional description, drive
The ProMinent
®
Sigma/ 1 diaphragm-type metering pump is an oscillatory displacement pump
with the stroke length adjustable in steps of 1%. It is driven by electric motor
(1)
. The rotary drive
of the electric motor is stepped down by worm gear and transmitted via the eccentric roller
(3)
to
the push rod
(4)
connected to fork
(8)
and converted into oscillatory movement. Return spring
(5)
presses the fork with push rod positively against the eccentric roller thus producing the return
stroke. The stroke is adjusted by means of stroke adjustment knob
(6)
and spindle
(7)
by limiting
the return stroke. Stroke movement is transmitted directly to the displacement diaphragm.
Interacting with the valves, this diaphragm produces the overpressure and vacuum in the liquid
end necessary for delivery. Flow is pulsating.
In the basic type, the electric motor is normally a 3-ph extended-range AC motor (refer to
Section 3 for other options).
