Diaphragm Mini Pumps
By Design Engineering StaffFluid Power KNF pump
KNF pump series allow for design-to-fit customization.
KNF introduced its N85-N815 Series of diaphragm mini pumps that handle gases, take samples (even liquids in a vacuum) or evacuate vessels. All standard pump models in the series can be modified in terms of performance, head materials, stages, wetted coatings, motor, connections, tubing, and mountings.
Ranging from 0.56 kg to 1.8 kg, all models in the series feature a structured diaphragm; operate without oil; and integrate tough valve structures to handle vapor and condensation. Depending on model, standard mini pumps can provide flow rates up to 20 l/m, achieve up to 27 in. hg vacuum levels with a single stage, and operate against pressures up to 35 PSIG.
