Before using any Fluid Metering, Inc. product read the following safety instructions
as well as specific product specifications and operating instructions.
Warning! Fire, electrical shock or explosion may occur if used near combustibles
explosive atmosphere, corrosive air, wet environment or submerged in fluid.
STH/Q SET UP INSTRUCTIONS
!
Caution! Fire, electrical shock, injury and damage may
occur if not used in accordance with Fluid Metering, Inc.
specifications and operation instructions.
Do not put wet fingers into power outlet of unit.
Do not operate with wet hands.
Do not operate drive assemblies that require a hard mount
(to be bolted down) unless they are mounted per Fluid Metering, Inc.
specifications, if not injury may occur and/or damage to unit.
Do not touch any rotating pump or motor components: injury may
occur.
Do not run pump dry, unless designed for that service.
Running dry is harmful to the pump, and will cause excessive heating
due to internal friction.
Check pump rotation and inlet/outlet pump port orientation before
connecting power to pump. If not injury may occur.
When pulling out cords from outlets do not pull cord, grasp plug to
prevent plug damage or electrical shock.
Fluid Metering, Inc. Drive Motors become HOT and can cause
a burn. DO NOT TOUCH!
Turn off the electrical power before checking pump for any problems.
Connect motor, speed controllers, or any other electrical devices
based on Fluid Metering Inc. specifications. Any unauthorized work
performed on the product by the purchaser or by third parties can
impair product functionality and thereby relieves Fluid Metering, Inc.
of all warranty claims or liability for any misuse that will cause
damage to product and/or injury to the individual.
Power cables and leads should not be bent, pulled or inserted by
excessive force. Otherwise there is a threat of electrical shock or fire.
Replace any inline fuses only with fuse rating as specified by Fluid
Metering, Inc.
When pump/drive is under operation, never point discharge tubing
into face or touch any rotating components of pump.
In a power down thermal overload cut-in condition, unplug or turn off
power to pump. Always allow a cool down period before restarting:
otherwise, injury or damage may occur.
For 30 seconds after power is removed from pump/drive: do not
touch any output terminals. Electrical shock may occur because of
residual voltage.

2.0 GENERAL SET-UP
2.1 Setting Dispense Stroke Rate
Strokes Per Minute (spm): For fluids of 500cps
viscosity or less a stroke rate of 120-350 spm max is
ideal. For fluids with greater than 500cps a slower rate
is recommended.
2.2 Fluidics:
Inlet (Suction) Tubing: To avoid cavitation use the
most resilient tubing possible with the largest
inside diameter (I.D.)
Outlet (Dispense) Tubing: For best dispense
performance use rigid Teflon tubing (to reduce
peristaltic action) with an equal or smaller I.D. than the
inlet (suction) tubing.
REQUIRED TOOLS:
1.Analytical Pan Balance
2.Hex Key Driver for Adjusting Stroke Length:
STH: 3/32" Hex Driver
STQ: 7/32" Hex Driver
3.A removable wicking thread lock (loctite 290)
1.0 PUMP MOUNTING: For optimum pump per-
formance it is recommended that your FMI pump
be mounted in a vertical position with the pump
head down in a 6:00 o'clock position and the motor
at 12:00 o'clock.This orientation will allow air bub-
bles that enter the pumping chamber to directly exit
through buoyancy assistance. Figure A

2.3 Step Motors:
FMI STH and STQ standard pumps are supplied
with a 23 frame, 1.8°/ step, hybrid 8 lead step motor.
For wiring diagram and detailed motor specifications
see Figure F
2.4 Rotational Sensor:FMI STH and
STQ standard pumps are supplied with an LED
rotational sensor. For wiring diagram and sensor
details see Figure G .
2.4.1 For sensor use with FMI SCST-01 Step
Motor Controller
see SCST-01 instructions.
3.0 CALIBRATION AND TESTING
3.1 Flush the system: clean with alcohol
or other suitable cleaning/wetting agent
before using the hydraulics and pump for the
first time. Prime pump with fluids to assure
system is free of air bubbles.
3.2 Place pump in the standard "home"
position with the piston-flat perpendicular to
the inlet port.The inlet port will be on the left
when the motor rotates clockwise (see
Figure B for the STH pump and Figure C for
the STQ pump).

3.3 Check the pump's dispense volume by
cycling the pump for one complete 360°
revolution (one complete rotation). Dispense onto
an analytical pan balance and observe the volume.
See Figure D. Readjust as necessary.
REMARK: When dispensing water-like solutions
assume 1 ml = 1 gram. A correction factor will
be required for other fluids.

3.4 Dispense Volume Values for FMI
STH/STQ Pumps:
NOTE: To assure the best performance set the pump
displacement volume as large as possible. FMI pumps
are calibrated at the factory to the maximum value.
Both STH and STQ pumps can be adjusted down to as
little as 10% of the rated flow.
3.5 Adjusting Dispense Volumes:
To adjust dispense volumes rotate the stroke-length
adjustment screw using the appropriate hex driver
(see Required Tools on page 1). To increase the flow,
turn the screw counter-clockwise. To decrease the
flow, turn the screw clockwise
CCW=Increase, CW=Decrease.
CAUTION: DO NOT LOOSEN THE HEX LOCK
NUT WHEN ADJUSTING THE STROKE RATE. IT IS
SET AT THE FACTORY AND SHOULD NOT BE
TAMPERED WITH. See Figure E
3.6 Lock setting: Once the pump is calibrated apply
a drop of removable wicking thread lock between the
lower pivot pin and the adjustment screw threads.
See Figure E.
3.7 Dispensing Hints:
1) Speed - Optimum results for fluids 500 cps or
less is between 120-350 rpm.
2) Cavitation: Use the largest suction tubing you
can to avoid cavitation.
3) Splashing can usually be avoided by
modifying dispense tip to larger I.D.and/or
decreasing dispense speed.
4) Hanging drop at dispense tip can be avoided by:
a) Use of rigid discharge tubing
b) Small dispense tip
c) Increasing speed
5) High viscosity dispensing requires:
a) Large suction tubing
b) Pressurizing suction reservoir
6) Bubbles in discharge
a) Suction fitting leak
b) Cavitation
7) Need Help? Call, fax, or email us… We can
help solve almost any fluid control problem.
