Product description S2Ba/S2Ca
The liquid end can continue to operate in emergency mode, i.e. full operating pressure, no
leakage, even after diaphragm rupture, until the diaphragm has been replaced. We offer two
versions of the S3Ca with diaphragm rupture sensor:
• After a working diaphragm rupture, the pump stops and an ”error“ message/diaphragm sensor
signal is given.
• After a working diaphragm rupture, the pump will continue to run. An ”error“ message/
electrical signal is given.
A function plug is supplied which allows the pump to continue operating after a fault has
occurred (diaphragm rupture, failure of the diaphragm rupture sensor).
WARNING
• EX-pump only: Installations in potentially explosive atmospheres must be inspected by
an “accredited qualified” person. This applies in particular also for intrinsically safe
electrical circuits.
• EX-pump only: observe documents supplied with the sensor!
IMPORTANT
• In the case of the S2Ba, the customer should install a diaphragm rupture signal monitor
and/or ensure that the pump will stop after a diaphragm rupture.
• In the event of diaphragm failure, a contact signal is triggered as from 2 bar system
backpressure.
• Exact pump delivery can no longer be guaranteed after failure of the working diaphragm.
• The auxiliary diaphragm, Item 148, is a wearing part and must be replaced after failure
of the working diaphragm. The diaphragm rupture sensor lens, Item 156, should be
replaced after every diaphragm rupture.
