Page 9: Minor Faults, Causes And Remedies
Suction capacity ® The maximum suction lift of the ProMinent mikro g/ 5a metering pump with the liquid end filled is 4-6 m depending on the type of pump (see technical data). The suction capacity with the liquid end empty is lower (see technical data). - Page 10 ® ProMinent mikro g/5a Instruction manual Precision feeding pump mikro g/5a Red fault indicating light goes on: Take note of the flashing fault annunciation on the display. Further hints see instruction manual g/5a. Float switch does not switch off the metering pump when the minimum filling level is reached: Float is blocked: Remove deposits and clean float.
- Page 11 ® ProMinent mikro g/5a Instruction manual Precision feeding pump mikro g/5a Parts subject to wear In spite of carefully choosing materials and the optimum design of the seals they can possibly become defective. The plunger V packings are prestressed with disc springs from the side turned away from the medium so that an automatic adjustment of the V packing takes place until it is finally worn down.
