Electrical connection of the motors is shown on the enclosed terminal connection diagram and on the connection diagram provided on the inside of the housing. IMPORTANT Stroke length adjustment/control drives must only be operated with the pump running! Page 16 ProMinent ProMinent ® ®...
• Ensure the correct gas admission pressure (approx. 60–80 % of the mean operating pressure). • Observe the information provided in the operating instructions of the frequency converter if using pumps with speed control. Page 17 ProMinent ProMinent ® ®...
Refer to notes in product-specific operating instructions! • If metering pumps are sent for repair to the manufacturer or a ProMinent dealer, clean all parts which come into contact with the medium before shipping. Essentially, maintenance is restricted to checking the metering capacity and for leaks.
The EU declaration of conformity is attached for the whole pump (also for pumps without motors). The EU declarations of conformity, EU design inspection reports and the operating instructions manuals for the individual components are attached. Assemble No specific notes.

The following applies to all dosing pumps when metering combustible media: Start up and drain only under the supervision of an appropriately qualified person. • Observe the relevant national directives with regard to installation! Page 20 ProMinent ProMinent ® ®...
This can be evidenced by means of a declaration of conformity from the supplier (ProMinent) for the equipment in its entirety, or if components are delivered individually, by means of a document from the operator confirming the components to be explosion-proof.
“experienced personnel with the necessary expertise” (section 4.2). • These measures are prescribed by ProMinent as the minimum required for protection. If the operator is aware of other risks, it is his responsibility to eliminate these by implementing the appropriate measures.
