Oil-Rite manufactures Lubrication Systems specifically to customer requirements. All systems are engineered, designed, manufactured and fully tested at Oil-Rite. This is an example of a custom built Circulating Oil System.

This Circulating Oil System is a dual, independent system sharing a common reservoir. It has dual cast iron gear pumps, each providing 18 GPM minimum at 85 PSI. The dual 3 HP, 1160 RPM, TEFC motors are operated by 3 phase power at 230/460V 60Hz. The motors are also rated for operation at 7600 ft. altitude.

The 100 gallon capacity reservoir is constructed of welded steel. A top filler cap makes filling the reservoir quick and simple. The filler cap is equipped with an air filter and liquid strainer to help maintain liquid quality. A baffle in the tank separates sediment and reduces turbulence. Dual 100 mesh stainless steel suction filters inside the reservoir filter larger debris. A level transmitter located in the reservoir monitors the liquid supply.

This system is plumbed for continuous operation with a dual filtration system. The 23 micron filters feature spin-on elements to facilitate simple cleaning and replacement. Differential pressure gages are provided to monitor circulation and detect filter contamination.

Heaters can maintain a certain liquid temperature and assist in cold weather start-ups.  This Circulating Oil System features a 6300 watt screw plug immersion type heater.  The heater is mounted to the reservoir and housed in a NEMA 4 enclosure. It has an integral thermostat adjustable from 60° to 250° F. 

This system also features (2) liquid cooled heat exchangers to help maintain a constant oil supply temperature. The heat exchangers used with this Circulating Oil System are constructed with 316 stainless steel.  Each removes approximately 240,000 BTU/HR, and requires 20 GPM of cooling water at a 65° F maximum.  Dual thermometers displaying 0° to 250° F are located near each heat exchanger outlet to monitor temperature.

This Lubrication System features a NEMA 4 electrical enclosure containing motor starters, lights, switches, pump alternator relay and all electrical components connected to a terminal strip for customer interface connections.

Additional features:

• Dual pressure gages located near the system outlets, each displaying 0 to 160 PSI, of stainless steel construction.
• Spring loaded bronze check valves located at the system outlets to ensure fluid flows in only one direction.
• Dual cast-iron bypass relief valves are used to set system output pressure, adjustable from 30 to 100 PSI.
• Dual temperature transmitters with thermowells located in the reservoir, factory calibrated to provide 4-20mA output for 32° to 212°F temperature range.
• (4) pressure transmitters with digital display, located before and after each filter, 0-150 PSID range, with 4-20 mA output.
• Dual brass flow switches actuated at approximately 8GPM, rated 10 Amps at 120/250 VAC, in a NEMA 4 enclosure.
