Oil Circulating System Manufacturer in India
Application
S. P. introduce O. C. S. (oil circulating system.) which is best suited for paper industry, steel plant, sugar plant... Etc.
Working
In O. C. S. oil is sucked from reservoir with the help of pump and ejected on lubrication point. Through filter and cooler , oil is returned in the reservoir by returning line. Before pushing the oil again it should be clean with normal temperature.
Construction
In O. C. S. we use the gear pump /screw pump discharge up to 500 LPM driven by electric motor. Pump is connected with reservoir. Reservoir capacity is depend on pump discharge. In line filter , cooler and other control with the gauge fitted by standard tubing and fitting on strid
Features
- System are custom built, tailor made, packaged unit skid mounted, ready for installation and piping to parent machine, in simplex as well as duplex arrangements. Fabricated oil tank to hold required quantity of oil with accessories i.e. Mahole, breather cum filler, oil level indicators, level switches for level control, baffles, drain valve, heater etc.
- Rotary gear, screw or centrifugal type pumps with built in relief valve, connected with electric motor. Filters of basket, self cleaning type, micron rating 10 micron onward depend on application. Material of element S.S wiremesh, paper, felt, fibre etc.
- Oil cooler to cool oil, horizontal or vertical, shell and tube type, plate type etc.
- Instrument panel consisting of pressure gauges, pressure switches, temperature gauges, temperature switches, RTD, flow switch, level switches, etc to keep control of the different parameters.
- Control panel is designed for higher degree of sophistications to control above, parameters and automatic changeover of pump, oil coolers, filters, change of flow path.
- Various valve are incorporated, check valve, gate, globe, ball, plug, relief valve, pressure control valve etc.
What Is an Oil Circulating System?
An oil circulating system (OCS) is a closed-loop lubrication system in which oil is continuously pumped from a central reservoir to the lubrication points on a machine, and then returned — via a drain or return line — back to the reservoir for filtration, cooling, and recirculation. Unlike a total-loss system where oil is discharged and not recovered, an OCS reuses the same oil continuously, making it economical and suitable for high-volume, continuous-duty applications.
The system is custom-built as a skid-mounted unit, pre-piped and pre-wired, and ready for connection to the parent machine. SP Engineers designs and manufactures oil circulating systems from Faridabad, India for steel plants, paper mills, sugar plants, rolling mills, and other heavy industrial machinery.
Key Components of an Oil Circulating System
| Component | Function |
|---|---|
| Oil reservoir / tank | Stores the system oil volume; includes breather, level gauge, drain valve, and baffles |
| Gear / screw pump | Draws oil from the reservoir and delivers it under pressure to the lubrication points |
| Electric motor | Drives the pump; sized to match the required flow rate and pressure |
| In-line filter | Removes particulate contamination from the oil before it reaches the machine |
| Oil cooler | Reduces oil temperature on the return line — shell-and-tube or plate type |
| Pressure gauges & switches | Monitor system pressure and trigger alarms on low-pressure conditions |
| Temperature gauges & switches | Monitor oil temperature; shut down the system if overtemperature is detected |
| Relief valve | Protects the pump and system from overpressure |
| Flow switch | Confirms oil flow is present before machine operation begins |
| Control panel | Automates pump start/stop, monitors alarms, and controls oil cooler operation |
When to Use an Oil Circulating System
An oil circulating system is the right choice when:
- The machine generates significant heat at bearing or gear surfaces that must be carried away by the lubricant
- High-volume continuous lubrication is required — such as in rolling mills, paper machines, or large gearboxes
- Oil cleanliness is critical and filtration on the return line is required to extend machine life
- The total oil volume in the system is large enough to justify recovery rather than total-loss dispensing
For applications requiring only small, intermittent oil doses — such as CNC machine tool guideways — a centralized oil lubrication unit with metering cartridges is typically more appropriate.
