Description

The BCD350 bench allows the study of the pressure losses of the various piping components (elbows, fittings, valves and pipings).

A pump sucks water from a tank and sends it in a hydraulic circuit comprising all the components.

It is equipped with a measurement outlet differential pressure with quick connectors and a water column manometer with scale.

Users will need to vary the flow rate of water and measure the pressure losses of the components.

The bench is equipped with a precision flowmeter which allows to study the relation between flow rate and pressure drop for each element.

It also allows the study of centrifugal pumps of the same characteristics.

It is also equipped with two pumps, the latter can be studied alone, coupled in series or in parallel. Users will select different couplings and measure the following characteristics: flow rate, suction pressure, discharge pressure, rotational speed electrical power for different operating points. The robust design of this equipment makes it perfectly suited for school use.

Its anodized aluminum structure on wheels makes it very robust as well as a great flexibility of integration into your premises. The manufacturing of this equipment meets the European machine directive.
