Three New Versions in the N 96 Pump Series

Three new versions of the compact N 96 are now available. One includes an AC/DC converter, one features a stainless steel pump head and one an aluminum pump head. These new options allow for a broader range of applications, now encompassing the handling of valuable and hazardous gases such as tritium. Demanding media which may require greater gas tightness – such as hydrogen, nitrogen and helium – can also be handled safely.

The EPDM or PTFE-coated diaphragm ensures safe use with aggressive and/or corrosive media. Its chemically resistant design and very high tolerance of vapor and condensate means the N 96 can be used with a broad spectrum of media at temperatures of up to 70 degrees Celsius. These pumps can transfer, evacuate and compress media oil-free and without contamination.

The new versions of this pump offer significant advantages when integrated into other devices. The wide-range power supply unit mounted to the compressor housing enables the pump to be used across the globe, regardless of the local power grid voltage. The pump head can also be rotated in 90-degree intervals, allowing for the connections to be positioned as needed. Fastening holes located on the side of the pump housing facilitate tubeless connection via o-ring adapters attached to a manifold.

The N 96 with a stainless steel pump head is typically used as a gas sampling pump for temperature-controlled media. It is mounted upside down such that even large portions of condensate can be safely drained.

Since the highly efficient brushless DC motor can be controlled by PWM, a control loop can be established and even complex operating profiles can be dynamically represented. The N 96 emits relatively little heat itself while being suited for use at ambient temperatures of up to 50 degrees Celsius. The pump can start up without discharge in the range of 2.5 bar relative pressure to 100 mbar abs vacuum. The flow rate is as high as 8.5 l/min. If necessary, the pressure can be increased to up to 4 bar g – a distinct advantage for obtaining zero air in filter systems with back pressures of up to 3 bar.
