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 equipped with a cast iron pump providing 2 GPM at 5 PSI.  The 1/3 HP, 1725 RPM, TEFC motor is operated by 3 phase power at 208-230/460V 60Hz.  This system is designed to lubricate (2) bearings.

The 10 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.  There are (2) 1” female NPT returns and (2) 1/2” female NPT drains.  A baffle in the tank separates sediment and reduces turbulence.  A 100 mesh stainless steel suction filter within the reservoir filters larger debris.  A low level switch inside the reservoir can be wired to shut down machinery or turn on warning devices when the liquid supply fails or recedes to a predetermined level.  The wiring can be accessed using the conduit box and relay.

This system is plumbed for continuous operation with dual filtration systems.  The (2) 23 micron, 1000 beta filters located near the outlets help maintain liquid quality.  One filter can be serviced while maintaining continuous system operation using the duplicate filter.  The filters feature spin-on elements for ease of cleaning and replacement.  Dual differential pressure gages (one located across each filter) are provided to monitor circulation.

An air cooled heat exchanger maintains a constant oil supply temperature.  It removes approximately 21,000 BTU/Hr.  This system was designed for an application where oil circulates in at about 190° F and out at 140° F.  The 1/12 HP, 1625 RPM, TEFC fan motor is operated by 3 phase power at 230/460V 60Hz.  A temperature switch is used to control the fan motor.  It is located near the heat exchanger inlet and adjustable from 75° to 200° F.

Heaters can maintain a certain liquid temperature and assist in cold weather start-ups.  This Circulating Oil System features a 1500 watt screw plug immersion type heater.  The heater is mounted on the side of the reservoir and housed in a Nema 4 enclosure.  The heater has an integral thermostat adjustable from 60° to 250° F. 

Additional controls include:

·          A bronze check valve located at the system outlet to ensure fluid flows in only one direction. 

• Dual, steel needle valves located at the system outlets, used to control oil flow to (2) bearings with (2) ½” female NPT oil outlets.
• A bypass relief valve used to set system output pressure, adjustable from 3 to 15 PSI.
• A dial thermometer displaying 0° to 250° F located near the heat exchanger’s outlet.
• A stainless steel pressure gage located near the system outlet, displaying 0-30 PSI.
• A 5” centerline liquid level gage on the outside of the reservoir with a dial thermometer displaying temperatures from 0° to 250° F, allowing visual check of liquid level, condition, and temperature at a glance. 

All Circulating Oil Systems are quoted specifically to customer requirements.  Pricing can be determined only after the Circulating Oil System Request Form (found on this page) is completed.  Contact the bearing manufacturer for information on the flow rate and fluid required.
