CAUTION!
Warning of feed chemical spraying around
An unsuitable feed chemical can damage the parts of
the pump that come into contact with the chemical.
– Take into account the resistance of the wetted mate‐
rials and the ProMinent Resistance List when
selecting the feed chemical - see the ProMinent
Product Catalogue or visit ProMinent.
CAUTION!
FDA pumps only: problems with hygiene possible
The O-rings supplied can become slightly contaminated
through packaging and shipment.
– Thoroughly clean the O-rings supplied before use.
CAUTION!
Warning of feed chemical spraying around
Pumps which are not fully installed hydraulically can
pump feed chemical from the outlet opening of the dis‐
charge valve as soon as they are connected to the
mains/power supply.
– First install the pump hydraulically, then electrically.
– In the event that you have failed to do so, turn the
multifunctional switch to
On / Off switch or Emergency Stop switch on site.
CAUTION!
Warning of feed chemical spraying around
Feed chemical can spray out of the hydraulic compo‐
nents if they are manipulated or opened due to pressure
in the liquid end and adjacent parts of the system.
– Disconnect the pump from the mains power supply
and ensure that it cannot be switched on again by
unauthorised persons.
– Depressurise the system before commencing any
work on hydraulic parts.
CAUTION!
Danger from rupturing hydraulic components
Peak loads during the dosing stroke can cause the max‐
imum permissible operating pressure of the system and
pump to be exceeded.
– The discharge lines are to be properly designed.
CAUTION!
Danger of personnel injury and material damage
The use of untested third party parts can result in per‐
sonnel injuries and material damage.
