6.3.5.2 Quench version (optional)
HILGE pumps with quench seal are equipped with a radial packing ring.
The pressureless flushing fluid is located between the mechanical seal and the
radial packing ring.
Connect the piping as described in Figure 9, Page 31.

Permissible supply pressures and temperatures
The supply of the mechanical seal with flushing fluid must be unpressurised. The
maximum overpressure must not exceed 0.2 bar.
When using pass-through flushing, secure the flushing fluid port with a pressure
reducer or the like if necessary.
When using a closed flushing circuit with a supply reservoir, regularly monitor the
fill level (visually or by means of level probes).
Also make sure that no pressure build-up can occur in the flushing circuit. Keep
the reservoir open to the atmosphere.
For critical media, regularly change the flushing fluid.
The maximum temperature of the flushing fluid must be 20 K below the boiling
temperature of the flushing fluid at the outlet.
The temperature rise in the pump flushing chamber is normally less than 10 K
(inlet/outlet).
The maximum permissible operating temperatures of the flushing device must not
be exceeded.
