-40 °C to +70 °C [-40 °F to +158 °F]
Upright, i.e., with the reservoir at top

Lubricating greases up to and including NLGI 2
Lubrication oils with at least 40 mm

/s (cST) at ambient temperature
• Chisel paste (see section “Lubricants”)
Depends on the pump design:
•
Filler nipple
Reservoir cover (with reservoirs without a follower plate)
Optional fill connection
1)
The specified ambient temperature range requires that the lubricant used can be pumped at the given ambient
temperature. The upper limit of the ambient temperature is load-dependent and is determined primarily by the running
time and the operating pressure. The cyclic duration factor specified is applicable for NLGI 2 lubricants, an ambient
temperature of 60 °C [140 °F], and a mean back pressure on the pump element of 160 bar [2321 psi]. The maximum ON
time should be reduced in the case of temperatures ≥ 60 °C [140 °F] and heavy loading (meaning higher pressure). UL-
certified pumps can only be operated up to a maximum permissible ambient temperature of 60 °C [140 °F] regardless of
the loading.
2)
Rotary installation is possible for pumps with a follower plate, e.g., in wind turbines. Maximum speed and maximum
distance to the rotational axis can be specified on request. If pumps without a follower plate are expected to be installed
in an inclined position (e.g. on construction or agricultural equipment), the following applies:
– The maximum filling must be reduced in accordance with the inclination to be expected (< MAX mark).
– The minimum fill level must be increased if the expected inclination is more than 30° (> MIN mark), otherwise
functioning could be impaired due to a reduced amount of lubricant in the suction area of the pump.

Observe the restrictions in the section “Operational limits of the intermittent empty signal.”
