DC-BI Pump Drive: Innovative Motor Technology for KNF Pumps
Advanced Pump Drive Technology for Diaphragm Pumps
KNF offers a variety of pumps with brushless direct current (BLDC) pump motor technology. With these in-house developed pump drive units, KNF pushes the technical limits of diaphragm pumps, once again offering unique and significant advantages for customers. The advanced motors combine outstanding durability, compact dimensions, and many options for digital customization.
Maximum Performance-to-Size-Ratio and Lifetime
‘Direct Current Brushless Integrated’ (DC-BI) uses a modern BLDC pump motor. While developing the new pump drive unit, KNF put special emphasis on maximizing service life and compactness. For the first time in diaphragm pump technology, the motor has been fully integrated into the pump housing.
This unique integration allows for unprecedented compactness and light weight, as well as optimized bearings. The drive unit uses larger than normal ball bearings for maximum lifetime. In addition, the ball bearing configuration has been optimized by cutting out a third ball bearing commonly found in conventional pump setups. By manufacturing the entire pump drive unit in-house, KNF is also less dependent on a single supplier, further increasing product availability and order reliability.
Full Digital Customization of BLDC Pump Motor Possible
As DC-BI uses a modern BLDC pump motor and KNF has full control over electronics and software, comprehensive digital customization is possible. This allows for sophisticated parameterization of aspects such as motor speed range, motor speed ramp, threshold values or error message output. With so many options for customization, the new series using DC-BI can be adapted to a multitude of requirements, making them suitable for almost every field of application.
KNF DC-BI Gas Pump Series
Currently, six KNF diaphragm gas pump series are available with DC-BI pump motor technology: KNF NMP 830 DC-BI, NMP 830.X DC-BI, NMP 830 HP DC-BI, NMP 850 DC-BI, NMP 850.X DC-BI and NMP 850 HP DC-BI. These micro gas pumps can handle most gases at a flow rate of up to 8.5 l/m and with a maximum pressure of up to 3 bar. They achieve up to 55 mbar abs for vacuum generation.
Combined with their advanced DC-BI pump drive technology and many customization options, they are suitable for even the most demanding applications such as medical equipment, environmental monitoring, inkjet technology or analytical instruments.
KNF DC-BI Liquid Pump Series
A DC-BI motor is standard on KNF’s FM 50 liquid diaphragm pump for precise and accurate metering. The ability to parameterize motor speed range, speed ramp, and threshold values allows for maximum flow control. The FM 50 offers a maximum flow rate of 0.5 l/min, maximum pressure of 1 bar (rel.), and maximum suction height of 3 mH2O. DC-BI motors are available with other KNF liquid diaphragm pump series’ on a project basis.
In addition to the extensive control provided by DC-BI motor technology, KNF liquid diaphragm pumps offer self-priming and maintenance-free operation with a compact design. Their construction allows for contamination-free media transfer, while also providing low pulsation and high resistance to aggressive media. KNF Liquid diaphragm pumps are strong choices for medical, inkjet, food and beverage, and many other applications.
