3.4 Lubricaon data
Note:
Manufacturers Material Safety Data Sheets for the oils specied below are available
upon request.
Table 4 Lubricaon data
Hydrocarbon pumps:
Recommended oil* Ultragrade 19
Maximum oil capacity 1.32 litres
PFPE - prepared EM pumps:
Recommended oil* Krytox 1506 or Fomblin 06/6
Maximum oil capacity 1.32 litres
* To operate the pump when the ambient temperature is outside the range specied in
Operang and storage condions on page 12, or to opmise pump performance when
processing condensable vapours, a dierent oil may be used.
3.5 Electrical data
Refer to Table: Electrical data: three-phase motors on page 15 and Table: Electrical data:
single-phase motors on page 15. For motor current informaon please refer to the
motor rang plate. The motor start-up current is drawn for less than one second, so
me-lag fuses must be used to prevent unnecessary fuse failure when the pump starts.
Fuses should be to EN60269 Performance on page 12. If using the pump at temperatures
lower than 13 °C, the start-up current will be drawn for longer; this may cause the motor
thermal overload device to open.
