Example:
KFG pump unit (KFG) without internal control
unit, with lubricant reservoir size of 8 kg (4),
pump housing design (5) with switching point
fill level monitoring for minimum for external
output signal (E), with pressure relief valve for
a single-line system with a pump element and
integrated 200 bar safety valve (O), with
2.5 cm

/min. pump element mounted at
position 1 (AXX), with Ø 8 mm tube connection
(B), for rotary application (0002) with operating
voltage of 230 V AC and protection class IP55
(230VAC) gives the following order number:
KFG4 -5EOAXXB0002-230VAC
1) Notify us of the setting
times for the control unit.
2) System is designed
according to customer's
specifications.
3) On a design with a
pressure regulating valve,
its cracking pressure and
tube diameter are to be
specified (see pages 11
and 18).
