On-Site Pump Parameterization: Maximizing Performance in the Field

BLDC Technology Enables On-Site Pump Customization

Flexibility is a key factor in today's rapidly changing industrial environment. For KNF diaphragm pumps, the integration of advanced BLDC motors, such as DC-BI or the recently introduced MI motor technology, enables sophisticated communication with the motors. This gives KNF unparalleled flexibility for on-site pump customization, even after the pump has been implemented in the customer's system. Proprietary management tools allow KNF engineers to fine-tune performance parameters, including speed ranges and control characteristics. For this purpose, KNF has developed and defined its own control protocol, which is transmitted via the Universal Asynchronous Receiver Transmitter (UART) serial digital interface.

This parameterization software allows seamless switching between digital and analog control modes, with options for motor speed control via pulse-width modulation (PWM) signals, analog control voltage, or digital setpoint specification. Custom configuration options for communication protocols and error handling ensure smooth integration into customers' new or existing systems. This adaptability makes BLDC driven diaphragm pumps particularly valuable in complex applications where operating conditions can vary.

Expert On-Site Optimization Process

The KNF approach to on-site parameterization delivers exceptional results through a comprehensive process: KNF engineers begin by conducting thorough performance evaluations under actual operating conditions, using sophisticated measurement tools to analyze real-world performance metrics. Proprietary software tools allow direct access and modification of motor parameters such as speed range, startup behavior, or thresholds such as electrical current or motor temperature, allowing immediate adjustments based on observed performance. This direct verification process ensures optimal alignment with application requirements, eliminates the need for multiple tuning cycles, and reduces development time.

Advanced Parametrization Tools

The specialized KNF software interface represents a significant advancement in pump customization technology. It provides full control of pump functionality through direct motor access, allowing immediate parameter adjustments without the need for disassembly. Continuous data transmission tracks real-time performance metrics while providing the ability to create customized parameter sets tailored to the customer's specific operating requirements.

Optimization Reveals Opportunities

On-site optimization often reveals opportunities for increased efficiency that may not have been apparent in the initial specification. By carefully analyzing the actual operating conditions and requirements, KNF specialists can often identify opportunities for improvement. In some cases, this analysis may reveal that a smaller pump can effectively handle the application, resulting in cost benefits while maintaining the required performance levels.

Another benefit of on-site optimization is the ability to address more complex system vibration conditions that may cause the diaphragm pump to generate unnecessary vibration or noise. By ensuring that the pump operates outside the frequency range of the customer's system, these effects can often be reduced or eliminated, providing a practical solution to challenges that are difficult to anticipate in theory alone. 

This practical, hands-on approach to pump selection and optimization helps ensure the most efficient and cost-effective solution for each application.
