Overview

Bijur Delimon International is a global supplier of Oil Recirculation Systems and Equipment, designed for the optimum lubrication of bearings, gear trains and other processes requiring oil for lubrication and cooling.

A range of standard Multi-Purpose Oil Circulating units is manufactured to fill the need for a relatively simple, inexpensive, yet reliable system where a custom design is not required.
Reliability is key to our success, achieved by utilizing proven design techniques, product quality, and competitive pricing.

In providing the key functions of an Oil Recirculation System, the system is built from the following primary equipment:

Tanks − to allow settlement, de-aeration, and heating with the ability to condition and change the lubricant as appropriate.
Pumps − typically motor driven gear pumps to provide the correct flow and pressure to the application.
Heaters & Coolers − to ensure the lubricant reaches the points of application at the required viscosity.
Filtration − to maintain the system cleanliness at the required level.
Instrumentation − monitoring for pressure, flow, filtration, temperature, and level.
Accessories − controls and wiring, pressure relief.

System Design

One electric gear pump draws oil from a reservoir and supplies the oil via check valves through a single or dual basket type filter to the delivery connection.

Standard Units Comprised of:

Reservoir: Fabricated from mild steel plate, sandblasted, and painted one coat primer with one coat of Light Grey (RAL7035).
Reservoir Components: Return and drain connections; level gauge; thermometer; air breather filler and filter.
Pump & Motor: Positive displacement integral gear type aluminum pump; 1500 rpm motor suitable for 380/440 VAC, 3phase, 50/60Hz supply.
Oil Filter: 25µ (nominal) stainless steel mesh element; high dirt load capacity; visual/electrical clogging indication; bypass valves.
Pressure Relief valve: Self-operating relief; easily adjustable relief spring pressure.
Pressure Indication: 63mm gauge; 0-16 bar pressure.
Check Valve, Pipe & Fittings: Screwed, mild steel.
Level Switch: 2 position digital level switch.

Optional Extras

Standard Units Comprised of:

Heater: 1kW, 3phase, 0.9W/cm² watts density; Thermostat.
Pressure Transmitter: 4-20mA analogue signal.
Oil Cooler: Shell & Tube type; cooling oil to 100°F from 122°F with water at 68°F (water flow = oil flow x2).
Electrical: Aluminum junction box.
Flow Switch: Viscosity compensating float type; SPDT contacts.
Tank Temperature: PT100 RTD and Thermowell
