INSTRUCTIONS
MODELS GPD, SPD PNEUMATIC DRIVES
FMI Pneumatic Pump Drives are similar in design to the standard FMI “Q” pump; please review the Q431
Instruction and Parts Identification Sheet.
OPERATION:
1. Follow all safety codes during installation of your FMI Pneumatic Drive.
2. Your Standard Pneumatic Drive Pump (SPD) or Gear Pneumatic Drive (GPD) must be rigidly
mounted using the four 9/32 Dia. holes in bracket Q648, see fig. 1. (Drives can be mounted
either horizontally on table or lab bench, or vertically on wall with pump head facing down).
3. Important. For proper rotation (clockwise) air must enter right port (use 1/8” NPT). All air
Lines should be clean and free of foreign matter. Install standard filter, regulator and
lubricator as close as possible to motor inlet port. The lubricant should feed oil at a rate of
one drop for every 50-75 CFM of air going through motor.
4. Air Requirement: SPD 9-10 CFM at 40 psi GPD 14-16 CFM at 40 psi. If reduced noise is
desired exhaust air can be run to some remote location away from work area using flexible
tubing, all lines should have minimal amount of bends, elbows, tees, etc.
5. Pump flow rates may be varied by simply regulating air flow to the motor. A typical speed
regulation system is composed of two pressure regulators, one on inlet line, and one on
outlet line.
MAINTENANCE:
1. Lubrication of Standard Pneumatic Drive: use detergent SAE #10 automotive engine oil.
2. Lubrication of Gear Pneumatic Drive: use a 300 SUS @ 100º F turbine quality lubricant. For
horizontal operation remove the two hole plugs, (see exploded view GPD on reverse side). Add
oil to one hole until second hole overflows. For vertical operation fill to overflow point of upper most hole.
