The specified enclosure rating of the pump requires the use of IP69K-compliant connection sockets and corresponding
cables. If connection sockets and cables with a lower protection rating are used, the lowest of those ratings will apply as
the enclosure rating. For the enclosure ratings achievable when using the connection sockets and cable supplied by us,
see the “Spare parts” chapter.
4.3 Nominal delivery rates
NOTE
The specified nominal delivery rates per stroke apply to NLGI grade 2 lubrication greases in the case of pump elements
5, 6, 7, and R and to NLGI grade
0 lubrication greases in the case of pump element L, in all cases at an ambient
temperature of +20
°C [68 °F] and a back pressure of 100 bar [1450 psi] at the pump element.
Differences in operating conditions or a different pump configuration will lead to changes in the motor speed and thus to
a change in the delivery rate per unit of time. If the change in the motor speed necessitates an adjustment to the delivery
rate per unit of time, then this will be reasonably accomplished by adjusting the lubrication and pause time setting of the
pump.

1)
The pump element L must not be used on pumps with a follower plate. With pump element L, lubricants below NLGI
Grade 2 as specified in these instructions can be pumped without restriction. For lubricants of NLGI Grade 2, the
suitability of the pump element L at temperatures of -5 °C or lower must be checked on a case-by-case basis.
2)
The pump element “C” is designed only for pumping chisel paste. When using chisel paste, observe the relevant
information in the “Lubricants” section.
