Detail „X"
M 5:1
max. 5.3 dia.
Important: Changes to the stroke length should only be made while the pump is
operating, when the adjustment bolt is temporarily relieved during the metering
stroke.
In the internally controlled, or manual mode, the stroking rate can be varied with the
keys (4) from 0-50 strokes per minute. The settings can be repreated with quartz
accuracy. The output flow is proportional to the stroking rate. The operation and
programming takes place as described in the enclosed instruction manual "ProMinent
gamma/ 5a". For the mikro g/5a however the maximum number of strokes per
minute is 50 as opposed to 120 as maximum metering rate and the flow monitor is
omitted.

3.2 Connection and initial operation

Screw the back pressure valve onto the liquid end. Assemble the metering pump on
a chemical tank or a bracket using screws and washers with a 5 mm diameter. The
valves of the liquid end must always be in a vertical position in order for them to
operate smoothly.
Connect suction and discharge lines.
Installing PTFE tubing on PTFE liquid end
Push screw fitting and sliding ring onto PTFE tube. Heat up the flange pin which
comes with the delivery package to approx. 60-80 °C. Then press the tube with
screw fitting and sliding ring onto the warm flange pin. To press it on a non-slip sand
paper or similar can be used. Please note: The tube should not be bent in doing so.
Connecting thread for screw fitting UNF 1/4"-28.

Installation of VA piping
When laying piping the VA piping length must be adjusted and fitted on the space
available. To cut piping lines it is best to use a piping cutter. For connection to the
feeding end first remove the PTFE tube with nipple. Push terminal nut, thrust collar
and bracing ring onto the pipe. Push the end of the pipe right into the bore. Then
place the thrust collar and the bracing ring on the connection. Screw on terminal nut
and tighten.
