nameplate. Refer to figure 1 and table 1 for instructional keys when using this manual.
External tubing is provided to bleed oil from both ends of pump (high pressure fluid) to pump suction. Shaft
bushings are lubricated by a fluid flow between power rotor and bushing that is released back to suction
through external tubing. In all cases, fluid flow through tubing ensures lubrication and cooling of bushings
and mechanical seal.
Normal rotation of pump rotor is clockwise when pump is viewed from shaft end.
Note:
Term outboard describes closed end of pump; term inboard describes exposed shaft end.
OPERATION
CAUTION
Operating conditions, such as speed, fluid viscosity, temperature inlet pressure,
discharge pressure, filtration, duty cycle, drive type, mounting, etc. are
interrelated. Due to these variable conditions, specific application limits may be
different from that of operational limitations. Equipment must not be operated
without verification that operating requirements are within its capabilities.
OPERATING TEMPERATURE AND THERMAL SHOCK EXPOSURE
Never operate with water. Pump is designed for liquids having general characteristics of oil. Under NO
circumstances are the following operating limitations to be exceeded:
Maximum Inlet Pressure ...................................................... 25 Psig
Maximum Discharge Pressure ..........................................300 PSIG
Maximum Speed ............................................................. 1200 RPM
Maximum Operating Temperature ......................................... 250
