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 2.5 GPM at 15 PSI. The 1/2 HP, 1750 RPM, TEFC motor is operated by three phase power at 380V/60Hz.

The 15 gallon capacity reservoir is constructed with 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 return connections 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 through the conduit box and relay.

This system is plumbed for continuous operation with dual filtration systems. The (2) 10 micron filters located near the outlets help maintain liquid quality. One filter can be serviced while maintaining continuous system operation using the duplicate filter.

A water cooled heat exchanger helps maintain a constant oil supply temperature. It removes approximately 12,600 BTU/Hr. In this application, water circulates in at about 124° F and out at 100° F.

Additional controls include:

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

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

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

·          A bronze flow switch located near the system outlet, set at 2 GPM.

·          A stainless steel, dual scale pressure gage located near the system outlet, displaying 0-60 PSI (0-400 kPa).

·          A stainless steel, dual scale dial thermometer located near the heat exchanger outlet, displaying 0° to 250° F (-20° to 120° C).

·          A pressure switch located near the system outlet, adjustable from .5 to 80 PSI, and housed in a NEMA 4 enclosure.  Set at 15 PSI.

·          Brass isolation ball valves located on the pressure gage and pressure switch.

·          A 7” centerline aluminum 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.

This custom built circulating oil system measures 30” by 21”. The overall height is approximately 37”.  The system can be secured using (4) mounting holes located on the base of the unit.

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.
