Bladder Integrity Systems

Bladder integrity System

HYDAC has developed a new product, the Bladder Integrity System, or BIS for short. It consists of BIS bladder, BIS adapter and electronic component BIS 1000.

The BIS detects fluid which has penetrated the bladder and transmits a signal. A split is therefore detected in the bladder. In addition, the temperature and pressure can be monitored electronically (current loop/HART). The BIS is available together with a bladder accumulator as initial equipment. A retrofit version is the BIS-bladder and is also available.


– Identifies defective bladder during operation → Planned repair/maintenance intervals → Reduction in down times

– Integrated pressure and temperature measurement: → Pressure and temperature monitoring of the accumulator during operation → Accurate adjustment of p0 and simultaneous temperature indication.

Applications: hydraulic accumulators with an emergency function such as mechanical seals, davits, unmanned plants like remotely monitored oil fields, etc…
