KNF N 86 KNDC-B (with BLDC motor)
Small in Size, Big on Performance

N 86 K series pumps are equipped with the patented stress-optimized diaphragm, resulting in a high pneumatic performance, a durable product and compact size. Meanwhile, special valves ensure that these pumps can deal with vapor and condensation easily.

Modular Design

Thanks to KNF Modular System, the components used to transfer the gases can be made from materials with varying degrees of resistance. This series can be driven by either AC, DC, or BLDC motors.

Moreover, versions with high resistance to chemicals are available (N 86 KTE, KTDC-B, and KTDC). Please contact us for more details.
