When coming into close contact with medical devices, patients primarily expect these devices to be quiet and produce minimal vibration. For the manufacturers, size, weight and reliability also count — a lot of requirements for the integrated pumps. KNF addresses these demands with the newly developed NPK 012 swing-piston pump, offering an economical and high-performance solution.
As a partner of the medical device industry, KNF took on the challenge of finding an economical solution that allows more leeway in particular for the manufacturers of hand-held devices for medically indicated aspiration. With the new NPK 012 swing-piston pump, the technology leader in the area of application-specific pumps and systems is introducing a compact, light-weight model that is both affordable and high performing.
In spite of its flow rate of up to 13.5 l/min, the NPK 012 has been cut down to nearly 30 % shorter than previous models in its performance class. This also has a positive effect on the new pump’s weight, bringing it down to 600 g and making this model perfect for mounting in hand-held devices.
The brushless DC motor allows for excellent control. With a low energy consumption of just 43 W, the NPK 012 builds up 2.5 bar of high, continuous positive pressure, and up to 5 bar during intermittent operation. The ultimate vacuum reaches 140 mbar abs. The NPK 012 delivers this high level of performance quietly and with minimal vibration.back
