Rotary valve vacuum pump, two stages, 115 V / 230 V

Function and Applications

Two-stage rotary vane vacuum pump suitable for continuous operation in the rough and fine vacuum range.

Benefits

• The pump is characterized by high water vapor tolerance and a compact design.
• Due to its low weight, small dimensions and high pumping speed, it is ideally suited for use in schools and laboratories.
• The pump is low-maintenance, compact and impresses with very smooth running.
• To reduce the risk of damage, the oil sight glass is integrated into the housing.
• The pump housing is particularly easy to clean.
• As an NS 19 standard taper is included, vacuum chambers and discharge tubes with an NS 19 socket joint can be mounted directly onto the pump.
