    No. 47900-2-02-5 page 4 of 28 Safety information! General information ☞ Read and comply with this manual before installing or operating the equip- NOTICE ment. ☞ Transport the pump at the provided handle. Remove all packing material, remove the product from its packing-box, remove the protective covers from the inlet and outlet ports and keep, inspect the equipment.
  • Page 5: Ambient Conditions

    No. 47900-2-02-5 page 5 of 28 • Comply with maximum permissible pressures at inlet and outlet and pressure differences, see section ”Technical data”. Do not operate the pump with overpres- sure at the inlet. • Check that mains voltage and current conform with the equipment (see rating plate).
  • Page 6: Operating Conditions

    No. 47900-2-02-5 page 6 of 28 Operating conditions ➨ The pumps have no approval for operation in or for pumping of potentially explosive atmospheres. ➨ The pumps are not suitable to pump unstable substances and substances which react explosively under impact (mechanical stress) and/or when being exposed to elevated temperatures without air, self inflammable substances,...
  • Page 7 No. 47900-2-02-5 page 7 of 28 • Comply with applicable regulations when disposing of chemicals. Take into con- sideration that chemicals may be polluted. Take adequate precautions to protect people from the effects of dangerous sub- stances (chemicals, thermal decomposition products of fluoroelastomers), wear appropriate safety-clothing and safety glasses. • Use only OEM spare parts and accessories. Otherwise safety and perform- ance of the equipment as well as the electromagnetic compatibility of the equip- ment might be reduced.
  • Page 8: Maintenance And Repair

    No. 47900-2-02-5 page 8 of 28 Maintenance and repair Wear parts have to be replaced regularly. In case of normal wear the lifetime of the diaphragms and valves is > 10000 operating hours. Bearings have a typical durability of 40000 h. Motor capacitors have a typical durability in the range of 10000 to 40000 h de- pending strongly on the operation conditions like ambient temperature, humidity or load.

  • Page 12: Use And Operation

    No. 47900-2-02-5 page 12 of 28 Use and operation Installing in a vacuum system • Connection lines at the pump inlet have to be gas tight. Particles and dust must not be aspirated, the user has to provide appropriate filters if necessary. The user must ensure their suitability concerning gas flow, chemical resistance and safe- ness against clogging prior to use. • Connect an exhaust line gas tight at the pump outlet if necessary. Always dispose of exhaust gases appropriately (e.g. into a fume hood). If there is risk of release of dangerous or polluting fluids, install an appropriate system to catch and dispose of those fluids.
  • Page 13: During Operation

    No. 47900-2-02-5 page 13 of 28 • The gas outlet (hose nozzle 10 mm) must not be blocked. The exhaust pipeline has always to be free and pressureless to enable an unhindered discharge of gases. • If necessary connect the exhaust to a suitable treatment plant to prevent the dis- charge of dangerous gases and vapours to the surrounding atmosphere. During operation • Maximum ambient temperature: 40 °C • Make sure ventilation is adequate especially if the pump is installed in a housing or if the ambient temperature is elevated.
  • Page 14: Shutdown

    No. 47900-2-02-5 page 14 of 28 For condensable vapours (water vapour, solvents, ...): ☞ Do not pump vapour before pump has reached its operat- ing temperature. Open gas ballast valve when pumping condensable vapours. ☞ The gas ballast valve is open, if the arrow on the gas bal- ballast last cap is pointing towards the labelling ”GB”.

  • Page 16: Replacing Diaphragms And Valves

    No. 47900-2-02-5 page 16 of 28 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 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 17: Cleaning And Inspecting The Pump Heads

    No. 47900-2-02-5 page 17 of 28 Cleaning and inspecting the pump heads The replacement of the diaphragm and the replacement of the valves can be carried out separately. ☞ To replace the valves, remove the head covers of one side of the pump conjointly with the assembled valve heads and fittings.
