KNF Swing Piston Pump Provides Quiet Running at High Performance

The enhanced KNF NPK 012 swing piston pump is a powerful solution at an attractive price Compact, quiet and running with minimal vibration: With the NPK 012, KNF has developed a swing piston pump for use in medical devices, inkjet and 3D printing technology, and vacuum gripping systems. In response to customer requests, KNF has expanded the pump series to include several new versions, allowing for an even greater variety of applications. Printing process applications and medical technology benefit from the expansion of pump series When the NPK 012 was introduced in 2019, it proved to be just what the market needed: a powerful pump with special features. Thanks to its high-power density, it quickly drew attention and customers soon requested specifications that would expand the areas of application. KNF now responds with a product update that meets these requirements along with the desire for shorter installation times. Among the most striking changes is the electrical connector. Not only does it speed up the integration of the pump when compared with the previous model using stranded wire, it also protects the motor connection against reverse polarity. Based on long-term internal testing, the temperature range was expanded to accommodate media at temperatures of up to 60 degrees Celsius/ 140 degrees Fahrenheit. The tests showed that using the pump at higher temperatures did not adversely affect the lifespan of the product. KNF modular system provides additional options for swing piston pump Thanks to the KNF modular system, an optional cover is now available for the NPK 012 pump housing, which offers improved safety protection. This is especially useful when the device itself lacks sufficient protection and means less work for the customer and thus lower costs. An optional base plate with a flexible bore pattern makes mounting the pump a breeze and compensates for vibrations. The brushless DC motor allows for excellent control. With maximum power consumption of just 43 W, the NPK 012 builds up 2.5 bar/ 36.26 psig of high, continuous positive pressure, and up to 5 bar/ 72.52 psig during intermittent operation. The pump achieves an ultimate vacuum of up to 140 mbar abs/ 25.77 inHg, with a flow rate as high as 13.5 l/min. The NPK 012 delivers this high level of performance quietly and with minimal vibration. With a weight of just 600 g/ 1.3 lbs, the NPK 012 is also suitable for mounting in hand-held devices. Contact our KNF experts to learn more about the extended NPK 012 pump series.
