The U series comprises robust and durable oil-sealed rotary vane vacuum pumps with a simple design, direct drive and integrated recirculating oil lubrication. An oil cooler and the sound-insulated cover ensure low noise emissions and reliable operation.
The controlled oil return allows use in the rough vacuum range, while optional water cooling extends the oil life even under demanding conditions. An optional gas ballast reduces the condensation of vapours and protects the pump against a loss of performance.
The U series stands out for its low maintenance requirements, low operating costs, long service life and extensive range of accessories.
Standard operating conditions and performance
Operating principle
The Becker U series works on the proven principle of oil-lubricated rotary vane vacuum technology. An eccentrically mounted rotor with vanes rotates inside the pump housing, creating continuously changing working chambers. The air drawn in is compressed as the volume of the working chambers decreases and is then expelled through the outlet.
The pump oil performs important functions for lubrication, sealing and heat dissipation and thus supports reliable and efficient pump operation. Depending on the version, the pumps can be equipped with additional functions and components for different operating conditions.
The robust design and the proven rotary vane principle ensure reliable vacuum generation, a long service life and economical operation. The U series is suitable for numerous industrial applications and, depending on the model, can be adapted to different vacuum requirements.
