Accessories for vacuum pumps

Butterfly design. Housing made of stainless steel with fluoroelastomer seal. Two Buna-N rings act as rotary shaft seals. Helium leak-tested. Leak rate 1 x 10 ^-6 mbar x l/s. Excellent throughput....

The Pump combines a high flow rate with a very compact design. Suitable for filtration, SPE, and liquid aspiration using a vacuum. Due to the manual rotational speed control, the pump is quiet, very energy efficient, and can be optimally adjusted in accordance with the application.

• Easy-to-clean surface
• Very small footprint
• Adjustable in flowrate due to manual rotational speed control
• PTFE-coated diaphragm for use with aggressive/corrosive gases and vapors

The VACUU LAN ^® local vacuum network allows multiple work stations to be connected to a single vacuum pump. This is useful for almost any conventional vacuum application in a chemical laboratory VACUU LAN ^® can be directly incorporated into new laboratory installations or retro-fitted. All assemblies have integral check (1-way) valves. A practical and economical solution for multiple vacuum users in a single laboratory....

Antistatic PTFE. Flanges in grade 1.4305 stainless steel.
Virtually smooth internal walls to prevent accumulation of condensate or particles, provide high throughput with minimal turbulence.

• chemically resistant PTFE
• antistatic according to BS 2050:1978*, <10⁷ Ohm resistance between inside and flanges to prevent formation of electrostatic charges inside and outside, as required for ATEX applications.

Small flanges. Stainless steel. With male or female conical ground joints and DN flange as outlined below....

• Application: Rotary evaporation, Distillation, Multi-user vacuum system
• Easy to use to control the vacuum application
• Separate control unit with pressure sensors and two-step controlled valve to be placed independently from the operating unit
• Vacuum controller can be operated with components from KNF and other producers
