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 7.5 GPM 14.5 PSI.  The energy efficient 1 HP, 1140 RPM, TEFC motor is operated by 3 phase power at 380V/60Hz.

The 30 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 1/2” 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) 10 micron filters near the outlet help maintain liquid quality, allowing one filter to be serviced while maintaining continuous system operation using the duplicate filter.  A differential pressure gage and switch is provided to monitor circulation and can be wired to signal an alarm caused by high levels of filter contamination.  

A liquid cooled heat exchanger maintains a constant oil supply temperature.  It removes about 35,000 BTU/Hr.  This system was designed for an application where oil circulates in at about 135° F and out at 115° F.  A dial thermometer displaying 0° to 250° F is located near the heat exchanger’s outlet.

Additional controls include:

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

·          A bypass relief valve used to set system output pressure, adjustable from 7 to 35 PSI.

·          A bypass relief valve used for pump safety relief, adjustable from 30 to 100 PSI

·          A stainless steel pressure gage located near the system outlet, displaying 0-60 PSI.

·          A bronze flow switch adjustable from 2 to 8 GPM.

·          A 9” 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.  

Delivery is dependent upon supplier availability, lead times range from 4 to 10 weeks.
