Cooling-water data

Notes: 1. If any EH1200, EH2600 or EH4200 model pump is used in an ATEX system, the EH pump must be operated
with cooling-water. This is safety critical, and your system must incorporate a flow-switch (connected
to the cooling-water outlet) which monitors the flow rate of the cooling-water through the EH pump;
the flow-switch must be connected to your control system, which must be configured to shut down the
EH pump when the cooling-water flow through the EH pump is too low (see Table 14 for the minimum
cooling-water flow rates). Refer to the ATEX instruction manual for further details.
2. If any EH1200 model pump is not part of an ATEX system, you can operate the EH pump continuously
2
without cooling-water if the inlet pressure is kept below 5 mbar (5 x 10 Pa) and the pumpdown time is
no longer than 10 minutes.
