Synolex Circula Flush 22

Circula Flush 22 – Oil-System Flushing Fluid

Product Overview

Synolex Circula Flush 22 is a flushing oil for the planned preparation of oil circuits before they receive their service lubricant. Flushing is a separate maintenance operation: the fluid circulates through the agreed parts of the system to help carry removable contamination toward collection or filtration points. The ISO VG 22 designation identifies the grade used for this task. The product is intended for a defined flushing procedure with a clear start, operating method and completion point.

Product Identification and Grade

Key Features and Benefits

1. A dedicated preparation step

Using an identified flushing product separates circuit preparation from normal operation. This helps maintenance teams manage the temporary fill, circulation period and final drain as a controlled job. It also makes the oil used during the procedure easy to trace in the maintenance record.

2. Circulation through the planned route

The flushing fluid needs to reach the parts included in the cleaning plan. A defined grade helps establish the pump and flow conditions for that route. Valves, bypasses and temporary connections should direct the fluid through the intended sections rather than leaving important pockets untouched.

3. Transport toward filters and collection points

Circulating fluid can carry loose material through the circuit toward filtration or drain points. Effective removal depends on the filters, flow arrangement and the nature of the contamination. The procedure should therefore include collection and inspection rather than judging the result only by fluid colour.

4. Preparation for the next service fill

The purpose of the operation is a circuit ready for the intended lubricant. The final drain and management of retained fluid are important parts of that preparation. Synolex Circula Flush 22 should be used within a procedure that considers compatibility with the next fill and the amount likely to remain.

5. A defined end point for the work

Flushing is most useful when the acceptance criteria are set before circulation begins. These may relate to cleanliness checks, inspection findings or the equipment service procedure. Clear completion criteria help the team decide when to drain the temporary fluid and move to the service-oil charge.

6. Organised maintenance records

Recording the flushing product, quantity, circulation conditions and completion checks creates a useful history for the installation. That record supports future servicing and helps distinguish the temporary flushing operation from the subsequent period of normal machine lubrication.

Applications

Use Synolex Circula Flush 22 where an oil-based circulation flush is part of the equipment maintenance procedure. The product is not a substitute for mechanical cleaning when deposits or obstructions require physical removal. Define which components may operate during flushing and which must remain isolated. The procedure should protect the equipment while providing an effective route for removal of contamination.

• Planned cleaning of oil circuits before the main lubricant charge.
• Maintenance involving a controlled temporary circulation procedure.
• Preparation after component servicing where the equipment procedure calls for flushing.
• Lubricant change projects with an agreed compatibility and residual-fluid plan.

Viscosity and Grade Selection

The ISO VG 22 designation identifies the nominal viscosity class at the 40°C reference temperature. It is a grade reference, not a measured typical property for an individual batch and not the maximum operating temperature. This is a relatively low-viscosity grade within industrial oil classifications. It is selected where the equipment needs the corresponding flow and lubrication characteristics. As oil temperature changes, its viscosity changes too. The operating requirement therefore includes both starting conditions and the temperature reached during normal service. Use the current product data sheet to review the actual viscosity and any other properties required for the application. A different series with the same grade can still have a different intended duty. Keep the full product designation when comparing alternatives or placing an order, and use the equipment specification to decide whether a neighbouring grade is appropriate.

Performance in the Application

A flushing plan should describe the circuit as it will be used during the job. Filters, coolers, dead legs and isolated components can retain fluid or contamination if they are not included in the intended route. Flow through the easiest path does not necessarily establish circulation everywhere. Review the arrangement before starting and identify the points used to inspect or collect the result. The final service charge should begin only after the temporary fluid has been drained as specified and the system has been returned to its normal configuration. Flushing duration alone does not demonstrate that the agreed cleanliness objective has been reached.

Handling and Service

Follow the agreed circulation conditions and inspect temporary filters or collection points during the work. Drain the fluid from the specified locations, including accessible low points. Replace filters where required and confirm readiness before charging the service lubricant. Record any retained quantity that affects the final fill. Keep flushing containers and transfer tools clearly identified throughout the job.

Store the product in its original labelled container in a clean, covered area. Close the container after dispensing and use dedicated, clean transfer equipment. Protect the product from water and debris and keep batch identification legible. Follow the safety data sheet for handling and spill management, and manage used product through the applicable collection arrangements.

Why Choose This Product?

Choose Synolex Circula Flush 22 when a planned oil-circulation flush is required before the machine receives its service lubricant. It provides the temporary fluid for a controlled preparation stage. The practical benefit sought is a circuit ready for its next fill, with removable contamination collected and the completion of the work clearly established.

Product Selection and Ordering

For product selection or an order, provide the complete Synolex designation, the equipment or process application and the quantity required. Where a replacement is being considered, include the current lubricant name and the relevant equipment requirement. This allows the proposed product to be compared on application and documented properties. The current technical data sheet governs numerical specifications and any formal approvals. The comparison section below retains the product references and their qualifications, so that a potential alternative can be reviewed in its proper technical context.

Similar Products (Equivalent Matching)

The entries below support technical comparison. A documented comparator does not establish an automatically approved replacement. Conditional alternatives require the stated differences to be resolved. A family-level lead does not verify the exact grade, and the absence of a verified entry does not mean that no product exists in the market.
