Industrial dispensing and fluid application systems
Application-specific dispensing systems engineered for the precise metering and application of liquid, viscous and pasty media.
Dispensing systems ensure that the medium is supplied in a defined condition and metered and applied with high precision and repeatability. They are suitable for liquid, viscous and pasty media such as oils, greases, waxes, adhesives or silicones and are used wherever a medium must be applied to components in a controlled manner – manually, semi-automated or fully automated. In industrial applications, the performance of the dispensing system has a decisive influence on the process reliability of the overall system.
What is a dispensing system?
A dispensing system is an application-specific configuration comprising multiple metering and peripheral components that collectively perform a defined metering and application task.
Components such as pumps, valves and control units each fulfil clearly defined sub-functions. Only their precisely coordinated interaction enables the medium to be processed and applied with accuracy, stability and repeatability.
Functional Structure of a Dispensing System
The components used for implementation can be assigned to four functional categories.
Feeding and Supply
This category includes all components responsible for storing the medium, conveying it and supplying it at the required pressure. The objective is to provide the material continuously and in a process-stable manner for subsequent functions.
Transfer and Treatment
This category covers the transfer of the medium to the application point as well as its conditioning in accordance with the requirements of the dispensing process, including filtration, degassing, pressure regulation and pressure stabilisation.
Processing and Application
Components within this category are responsible for applying the medium. Metering and application are functionally coupled and together define the dispensing result. The metered volume and the resulting application pattern are determined by valve technology, application geometry and valve actuation.
Instrumentation and Control
Control and regulation components manage process control and synchronisation with the higher-level system. They stabilise the dispensing process and ensure reproducible dispensing results even under fluctuating process conditions.
Modular System Platform: Cost-efficient Implementation of Customised Solutions
For practical implementation, Walther offers a modular system platform in which individual system functions are realised through combinable components and assembled into compact dispensing systems. The modular architecture reduces project planning and engineering effort and supports cost-efficient system implementation. The use of proven, standardised components shortens planning times, minimises engineering risk and simplifies maintenance and service, thereby reducing operating costs and increasing system availability.
Design Principles of a Dispensing System
The design of a dispensing system is directly derived from the respective dispensing task. Application parameters such as the medium, metered volume, cycle time, application pattern and integration environment define the functional requirements of the system. On this basis, the required components are specifically selected and functionally coordinated to ensure stable and reproducible dispensing results.

System Design and Implementation of Dispensing Systems
Dispensing systems can either be configured by the customer from individual system components or supplied as fully engineered, assembled and tested units. Walther supports the system design, functional coordination and integration of application-specific dispensing systems – from the selection of suitable components through to commissioning-ready handover.
