Oil circulation systems


Oil circulation systems are chosen for multiple solutions in general industry. From a wide variety of applications, RIVI is focused to light and heavy industries.


A pump takes oil from the reservoir, and makes the oil pass through filters, heat exchangers, etc… until it reaches the flow meters which deal it proportionally & evenly to lube points. Later on, oil returns to the reservoir either by gravity or by means of pipe channels, in order to be recirculated again. This system is mainly used in bearings for: lubricate, refrigerate and avoid pollution. Lubricants to be used are: oils.


Applications & Industrial areas

- Hydrodynamic and hydrostatic bearings
- Turbines
- Steel rolling mills
- Gearboxes
- Pulp & paper machines
- Energy stations

Circulation systems can be classified in following groups:

- Hydraulic-by-Oil Flow Systems
- Lubrication Systems by means of Oil Circulation Flow
- Blocking Systems (used to preserve separation between points, for example: at different pressure)
- Control & Regulation Oil Flow

Oil circulation systems differ from each other, depending on client specification and requirements. RIVI’s expert engineers will always be ready to design a system which perfectly fits to the application requirements.

Light industry

Here are explained five possibilities (and different versions) for oil distribution.

1. Flow-strangle system

a) Strangling pipes
Flow control is adjusted proportionally to resistance value of strangle pipes. Flow per lube point can be from some cm3 up to several lts/min. There is no monitoring of different points; only main line pressure is possible to be watched over.

Economic system, with high functional safety.

b) Threaded stranglers and metering strips with adjustable stranglers
Flow control is adjusted proportionally to resistance value of threaded stranglers or adjustable metering strips. Flow can be from 0,2 to 230 cm3 and from 0,3 to 1000 cm3 .

There is not monitoring of different points.
Easy to plan and adjust oil flow.

c) Stranglers with oil flow electrical control
Flow control comes from stranglers, proportionally to resistance values, which are placed just before electrical & visual control devices.

Oil flow can be from 0,1 to 25 lts/min.

2. Volumetric regulators

Pump flow is distributed by these volumetric regulators, and then, by means of any strangling or progressive system.

Oil flow can be from 0,1 to 12 lts/min.

3. Progressive metering devices

A metering device distributes the pump oil flow; later on, oil flow can be sub-distributed again by means of more metering devices. Being combined with volumetric regulators, it is possible to supply lubricant up to 100 lube points or even more.

Oil flow: from some cm3 up to 6 lts/min.
Monitoring: optical & electrical, on metering devices.
Breakages are not monitored.
Exact adjusting, in spite of back-pressure.

4. Double line combined with progressive metering devices

Two-line metering device doses the amount of lubricant to progressive metering devices, which is supplied to every lube point.

Electrical monitoring
Exact adjusting, in spite of back-pressure.

5. Multiple outlets pumps (Multi-line system)

Multi-line pumps supply the lubricant directly to lube points. It is possible to include progressive metering devices, in order to monitor the operation.
