COMPARISON PUMPS

The pumps of the BT series make it possible to generate hydraulic pressures up to 800 bar necessary for the comparison calibration of manometers, pressure switches and transducers with standard gauges.
Their sturdiness and compactness make them easy to use both in the work shop and in the field.
Their installation and maintenance have been simplified as much as possible so that they may be used immediately.
