Product description

Glycerine pressure gauge – 100mm – Asta

Model 10HF – 1/4″ BSP type thread

Robustly constructed pressure gauge with reinforced mechanism and adjustment features. With the watertight case, it can be filled with damping liquid (glycerine or silicone).
They are particularly suited to installations subject to vibrations or line pulsations when filled with glycerine (standard for fire-fighting systems under NFPA-20).
Used to visualize the discharge pressure of centrifugal pumps. It must be installed on the pump’s discharge flange (diesel and electric motor pumps).
Assembled as a kit with damper and siphon tube on the pump’s discharge flange.
The scales of this model range from 0 to 10Kgf/cm² to 0 to 50Kgf/cm² depending on the project’s discharge pressure.
