The machine does not reach
the usual pressure on the
suction connection. Suction or discharge lines
too long or section diameter
too small. • Use larger diameter or
shorter lines.
• Seek advice from your lo-
cal Busch representative.
The operating liquid is too
warm.
(the characteristic curves are
based on 15°C warm water
as operating liquid, with
higher temperatures the
achieved pressure and the
flow rate deteriorate)
• Adjust cooling liquid flow
rate to reduce the tem-
perature of the operating
liquid.
• Check heat exchanger for
blockage.
• Check cooling liquid sup-
ply temperature and flow
