Engineering examples from real production environments
These examples show the type of reliability, maintenance and improvement work DEVA Maintenance Services delivers across manufacturing, industrial and commercial environments. Client names can be kept confidential where required.
DEVA Maintenance was brought in to investigate and improve a stainer dosing machine that had suffered ongoing reliability issues from new. Persistent blockages, pipe bursts, overflows and inaccurate dosing were creating repeated faults and making routine maintenance difficult.
The project focused on redesigning the filter and valve access arrangement, carrying out remedial repair work, and restoring the machine to a cleaner, more serviceable and more reliable condition ready for recalibration and production use.
The machine had suffered repeated faults including stainer blockages, pipes bursting, overflows, incorrect dosing quantities and dried stainer build-up within the system.
A major root cause was poor accessibility. The strainers, filters and ball valves were positioned directly underneath the canisters/tanks, making them extremely difficult to access, inspect and clean. Because servicing these components was awkward and messy, routine maintenance was not being carried out as effectively or as regularly as required. This contributed to contamination and restrictions within the pipework, leading to recurring blockages, pressure-related failures and poor dosing accuracy.
Once the mechanical work and testing were complete, the machine was handed back to production for calibration using their stainer product, ready for return to service.
The completed work significantly improved serviceability and access for routine inspection and cleaning. Moving the filters and valve arrangement to the outside of the machine made future maintenance much easier, cleaner and more practical.
