Diaphragm mini pumps

The N85-N815 Series of “built-to-suit” pumps offer a wide range of features and options. These mini pumps handle gases, take samples (even liquids in a vacuum), or evacuate vessels.

All models in the Series can be modified by selecting from an array of options, including performance modifications, various head materials, multiple stages, wetted coatings, motor types (ac, brush dc, or brushless dc with speed control), connections, tubing, and mountings.

The pumps weigh 0.56 to 1.8 kg, are equipped with a patented structured diaphragm for high pneumatic performance; operate without oil for uncontaminated flow of the pumped medium; and integrate tough valve structures to easily handle vapor and condensation.

Depending on the model, the pumps can provide flow rates up to 20 lpm, achieve up to 27-in.-Hg vacuum levels with a single stage, and operate against pressures up to 35 psig.
