OUTPUT ADJUSTMENT - INITIAL APPROXIMATION
A.
Speed control dial is graduated in approximate percent of maximum strokes per minute (spm).
Turning this knob clockwise increases pumping frequency.
OUtpUt EStIMAtE - total output of pump may be estimated by multiplying stroke frequency (percent of
maximum) by stroke length setting (percent of maximum). For example, if the stroke length knob is set at 100%
of maximum and the stroke frequency is 20% of maximum, total pump output will be approximately 20%; if
the stroke length knob is set at 30% of maximum and stroke frequency is 20% of maximum, total output will
be approximately 6% of the pump’s maximum rating. this is .2 x.3 = .06 or 6%.
B.
To determine exact frequency in strokes per minute at any speed knob setting, count number of
strokes for one minute.
C.
Stroke length adjustment knob is the lower of the control panel knobs. Adjust by rotating to desired
setting,while pump is stroking.
D.
SETTING—Maximum output of the pump is obtained with stroke frequency knob set at maximum
and stroke length knob set at maximum.
If pump is to be used at less than maximum output, best volumetric efficiency will be achieved if
stroke length knob is left at maximum, and stroke frequency knob rotated counter-clockwise to
reduce pump output. If more output reduction is required than can be achieved by reducing stroke
frequency, reduce output by turning the stroke length knob counter-clockwise .
E.
After installation is complete and an initial approximation setting has been made, the pump should
be calibrated and the stroke frequency and/or stroke length settings adjusted.
F.
Nominal output and pressure ratings are at 100% settings of stroke frequency and stroke length.
LMI accessories used with the Series E pumps must be placed in an explosion proof enclosure or located
in an area where they will not be subjected to explosion hazard.
WARNING:
These accessories are not explosion proof and must be installed remotely in a non-
hazardous area or mounted in an explosion proof enclosure. Wiring must adhere to local electrical
codes for hazardous locations.
E7 Series metering pumps come equipped with four external control wires for operating the complete line
of LMI accessories. Since hardwiring is essential for operating devices in hazardous locations, removal of
the four pin connector from the accessory is necessary. The chart below indicates proper wiring for each
accessory.
