Hydraulics
Centrifugal hydraulics with multi-channel impeller and vertical threaded connection on
the pressure side. If necessary, the pressure connection can be fitted horizontally. A
Storz coupling is fitted to the pressure connection.
The hydraulics are
not
self-priming, i.e. the fluid must flow in either automatically or
with supply pressure.
