V. Start-Up
A. Priming the pump
Plug in pump. While pump is operating, watch suction line. If fluid begins moving, no further priming
is required. If fluid is not moving, open bleed valve until fluid begins to move. When suction line
fills, close bleed valve.
Do not over tighten bleed valve, damage may occur.
Thumb and
forefinger are all that are required to tighten valve. Further tightening will cause damage to bleed
valve which will result in flow loss.

C. Adjusting Stroke Length
The stroke length can be adjusted on most MicroTron™ pumps. This adjustment is a mechanical
adjustment made using the large knob on the control panel. To avoid damage to the pump, this
adjustment should only be made while the pump is running at a high stroking rate.
D. Optional Features
1. External Pacing
The external pacing option allows the speed of the pump to be controlled by an external device
like a flow meter that gives dry contact switch closures. The pump sends out a 5 volt D.C. current
to read a switch closure. Each time the pump sees the switch closure it strokes once, up to it’s
maximum strokes per minute rate.
2. Hall Effect Meter Pacing
This option is like the external pacing only the pump divides the incoming switch closures by 9
before stroking on time. This is a three wire connection: D.C. voltage, signal and ground.
3. External Stop
Pumps with this option are allowed to stroke as long as they see a closed condition from a
dry contact source like a flow switch or drum level wand. When an open condition is seen the
pump is not allowed to stroke.
4. No Stroke Length Adjustment
Pumps with this option have no stroke length adjustment and no turn down capability. Their
output is fixed at the maximum.
