Series BT — hand comparison pumps

• Ranges 0...+400 bar and 0...+800 bar • Fluids: water - mineral oils • Built-in reservoir These comparison pumps allow pressure measuring equipment to be verified and calibrated. The laboratory for product studies, production for settings, the quality department for checks, maintenance for adjustments and the field for commissioning are the many applications of this equipment. The system offered carries out checks and calibrations at low cost. It consists of a pump that generates the pressure, to which are connected the equipment under test on one side and the pressure standard on the other: a mechanical or digital gauge, or a high accuracy pressure transmitter. The pressure generator consists of a handwheel driving a compressor piston, a liquid reservoir and two pressure connection pieces. It is set up on a bench. A single pump covers a very wide pressure range.
