5. Device description

5.1 Versions

If a servomotor is ordered together with a dosing
pump, the servomotor is fitted onto the pump at the
factory and subjected to a function test. Once on
site, qualified specialist staff must establish the
relevant electrical connection.
Servomotors can also be supplied for retrofitting on a
dosing pump, together with the necessary mounting
material. Such servomotors also undergo testing at
the factory prior to delivery. Qualified specialist staff
must fit the servomotor onto the dosing pump and
establish the electrical connection.
