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 mounted on a wheeled cart to allow mobility. It is equipped with a cast iron pump providing 12 GPM at 15 PSI. The 1 1/2 HP, 1735 RPM, TEFC, motor is operated by 3 phase power at 230/460V 60Hz.

The 45 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 through the conduit box and relay.

A 23 micron, 1,000 beta filter located near the outlet helps maintain liquid quality. The filter features a spin-on element to facilitate simple cleaning and replacement.  A differential pressure gage is provided to monitor circulation.

A water cooled heat exchanger helps maintain a constant oil supply temperature. The flat plate type 316 stainless steel heat exchanger removes approximately 32,000 BTU/Hr.  This system was designed for an application where oil circulates in at about 133° F and out at 120° F. A temperature switch is located near the heat exchanger outlet and adjustable from 75° to 200° F.

A temperature actuated modulating water control valve minimizes water usage.  The bronze valve monitors temperature at the heat exchanger’s cooling water outlet and adjusts flow accordingly.  It is adjustable from 60° to 140° F.

Additional controls include:

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

·          Dual steel needle vales located at the system outlets.

• A pressure switch located near the system outlet, adjustable from .5 to 80 PSI, and housed in a NEMA 4 enclosure
• A bypass relief valve used to set system output pressure, adjustable from 7 to 35 PSI (set at 15 PSI).
• A stainless steel dial thermometer located near the heat exchanger outlet, displaying 0° to 250° F.
• A brass flow switch located near the system outlet and adjustable from 5 to 15 GPM.
• A stainless steel pressure gage located near the system outlet, displaying 0-60 PSI.
• An 8” 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 48” by 24”. The overall height is approximately 36 9/32”.
