  • Page 17: Use And Operation

    page 11 of 22 Use and operation Installing in a vacuum system: ☞ Avoid throttling losses by using connecting pipes with large diameter and keeping them as short as possible. ☞ Reduce the transmission of vibration and prevent loading due to rigid pipelines. Insert elastic hoses or flexible elements as couplings between the pump and rigid pipes.

  • Page 21: Replacing Diaphragms And Valves

    page 15 of 22 Replacing diaphragms and valves All bearings are encapsulated and are filled with long-life lubricant. Under normal oper- ating conditions, the pump is maintenance free. The valves and the diaphragms as well as the motor capacitors are wear parts. If the rated ultimate vacuum is no longer achieved or in case of increased noise level, the pump interior, the diaphragms and the valves must be cleaned and the diaphragms and valves must be checked for cracks or other damage.
  • Page 22 page 16 of 22 Cleaning and inspecting the pump heads: ➨ Use open-ended wrench, remove screw-in fittings from all pump heads. ➨ To check the valves use hex key to remove four socket- head screws from pump head and remove housing cover with head cover, valves and O-rings (MD 4 / MV 2 only).
  • Page 23 Optimum torque for the diaphragm support disc: 6 Nm. ☞ The optimum torque is achieved if the pointer in the handle of the VACUUBRAND face wrench shows to the longer mark- ing line. Assembling pump heads: ➨ By turning eccentric bushing (front of connecting rod), bring connecting rod into a position in which diaphragm is in con- tact with housing and centred with respect to bore.
  • Page 24 page 18 of 22 Reassemble in reverse order. ➨ Install head cover (with O-ring if applicable), valves and hous- ing cover. ☞ Make sure that the valves are correctly seated : Valves at the outlet with round centred opening under valve, valves at the inlet with kidney-shaped opening beside valve.
