The characteristics of the hoseline:
Operating temperature -40° to +90°C or higher.
Connection thread generally G 1/4 or G 3/8.
Operating pressure > max. permissible operating excess pressure of the reciprocating
pump (about 400bar).
Electrically conductive, max. permissible resistance 3 x 10
4
1
/m (tested to ISO 8031).
The sealing head nipples of the hose fittings are made from austenitic stainless steel or
galvanised and yellow chromatised steel.
Surface lining:
The inside pipeline coating must be resistant to normal solvents,
- the outer coating resistant under certain conditions.
Free from any substances that may interfere with paint spraying such as silicone.
The nozzle or spray gun is installed at the end of the
hose line, connection thread G¼.
- Observe the relevant user information.
- When the nozzle/spray gun has been supplied by
us, user information has been provided.
In special cases, the fluid pressure connection at the reciprocating pump is connected to a
pipeline. The connection must be flexible (to avoid rupture caused by vibration).
The characteristics of the flexible pressure line
correspond to those of the connecting hose line.
Minimum rated width 8
In a large fluid pressure system and in cases
where the pressure system is influenced by heat
(sunrays, heating systems, etc.) it is necessary
to fit a suitable non-return valve between the
tube and the flexible pressure line (to prevent
damage caused by thermal expansion).
