Assembly

The ProMus pump is shipped complete from ProMinent and no assembly is required. A shipping
plug must be removed from the oil fill/breather vent hole and replace with the supplied orange
breather/ vent. The pump comes filled with oil.
The whole pump must be screwed onto a level and stable surface. For this purpose fasten the
pump with four screws (3/8 Inch or M10 Diameter Bolts and washers) through the four holes in
the base.

Installation

7.1

Installation: Hydraulic

WARNING
• If the pump is to be used with chemicals that are reactive with water, be sure to remove any
residue that may remain from factory testing. Feed low-pressure compressed air through the
suction valve to purge water from the liquid end.
• For Hazardous locations an external pressure relief valve must be installed downstream from
the liquid end to avoid potential hazards caused by blockage in the discharge line. In some
environments, heat generated by excessive fluid passing through the internal relief value may
cause temperatures of the pump housing to reach high levels.
IMPORTANT
For chemicals with a particle size greater than 0.01 in. (0.3 mm), install a strainer in the suction
line.
NOTE
If the metering pump discharges to atmospheric pressure, install a backpressure valve to create
a minimum backpressure of approximately 21.8 psi (1.5 bar).
Maximum admissible priming pressure (suction side): 14.5 psi (1 bar).
Viscosity limits maximum 200 mPa-s (200 cP).

Installation: Electrical

IMPORTANT
Motor
• For safe operation in hazardous environments, all electrical components, including motor,
electric stroke control and other devices must be rated for hazardous areas as described in
the National Electric Code.
• Articles 500 through 510 of the National Electric Code cover the requirements for electrical
equipment and wiring when flammable gases or vapors, flammable liquids, combustible dust,
ignitable fibers, or flying may create fire or explosion hazards.
• Connect the motor using the information provided on the motor nameplate. Motor rotation
should be counter clockwise looking down on motor (fan end). Also, read and follow
additional instructions in manuals provided with the motor.
• For pumps with an electric stroke adjuster, follow any supplemental instructions provided for
making electrical connections and operating the unit.
