DESMI PUMPING TECHNOLOGY A/S P a g e | - 22 -Tagholm 19400 Nørresundby - DenmarkPhone.: +45 96 32 81 11Fax : +45 98 17 54 99E-mail: desmi@desmi.comwww.desmi.comPumps for the food industry are preserved with vegetable oil.This can be applied by spraying in through both the inlet and outlet ports – if necessary bymeans of compressed air.4. For pumps intended for integration in an existing pipe system, the anti-corrosion oil can besprayed in through the manometer holes in the inlet and outlet ports, or through the borethat has been provided to connect a manometer.5. Fill the pump with sufficient oil for the oil to start running out of the pump.6. Then rotate the pump shaft manually so that all internal surfaces are lubricated.7. This process must be repeated every six months.8. In addition, the pump shaft should be rotated about 1/1 turn every month during the wholepreservation period9. If the pump is to be stores outside the pipe system, pipe plugs should be fitted on the pumpports during the whole preservation period9.3 Frost protectionPumps that are out of operation during periods of frost must be emptied of liquid to avoid frostdamage. You can use anti-frost liquids, but you must make sure that the elastomers used in thepump will not be damaged by the liquid used.10. InstallationAll items in this section must be read and observed when installing ROTAN pumps.10.1 Selecting the motor etc.All instruments and help systems used in connection with the ROTAN pump in potentiallyexplosive environments such as gears, motors and blocking liquid systems etc. should all beapproved by ATEX.Use only instruments and help systems approved by ATEX – such as gears, motors, liquidblocking systems etc. in connection with ROTAN pumps to function in potentially explosiveenvironmentsThe flange motor in and GP pumps must have a locked bearing at the end of the shaft end – aswell as vertically positioned pumps, to ensure that the pump’s axial clearance falls withinpermitted parameters.CC pump must have a angle bearing in non-drive end and wave springs in drive end
