OTEC relies on the new metering pump beta/ X
September 2025
OTEC Präzisionsfinish develops and manufactures machines for surface finishing. The company relies on high quality - and on the new metering pump beta/X from ProMinent. It ensures precisely controlled lubricant supply in the vibratory finishing process and impresses with its reliable performance, easy integration and high user-friendliness.
The finest surfaces for sensitive components
The surface treatment specialist builds vibratory finishing machines that deburr, smooth and polish metal parts. The workpieces come from industries such as medical technology, the automotive industry and jewellery manufacturing, and are often highly sensitive.
To ensure that the surfaces are processed evenly and precisely, the compound – the special fluid used in the vibratory finishing process – must be fed into the machine in exactly the right quantity. This is the only way to reliably achieve the desired quality.
The pump used previously performed this task reliably. But OTEC Präzisionsfinish wanted more: a more modern solution with greater ease of use, better maintainability and future-proof technology – without compromising on precision and robustness.
beta/ X metering pump - compact, precise, durable
The company now relies on the new diaphragm metering pump beta/ X. The pump meters lubricants with high repeat accuracy (± 1 %) and can be integrated directly into the machine control system via digital signals. Thanks to its robust housing (protection class IP65) and chemical-resistant diaphragm, it is ideal for continuous operation in industrial environments. The built-in stepper motor ensures high precision and consistent metering.
The beta/ X offers an intuitive user interface with a click wheel and display. OTEC Präzisionsfinish uses the pump in contact mode - a precisely defined amount of compound is metered during each machining cycle. The new PFAS-free PE diaphragm was successfully tested in the field at OTEC for over a year before the launch of the beta/ X - without any failures.
Stable processes, shiny workpieces
With the beta/ X, OTEC Präzisionsfinish has taken its metering technology to a whole new level. The pump operates reliably, meters precisely and is easy to maintain. This reduces downtime and increases process reliability - a clear advantage when processing high-quality workpieces.
The collaboration with ProMinent went smoothly: from expert advice and short delivery times to a personal contact who knows exactly what is required. OTEC Präzisionsfinish has relied on ProMinent's solutions and partnership-based support for many years.
