Weight of the empty pump
02 litres, approx. 6.5 kg [0.53 gal. approx. 14.3 lbs.]
04 litres, approx. 9.0 kg [1.06 gal. approx. 19.8 lbs.]
Filling
Depending on the specific pump type via:
- Filler fitting
- Reservoir lid (for reservoirs without follower plate)
- Optional filling connection
08 litres, approx. 10 kg [2.11 gal. approx. 22.0 lbs.]
11 litres, approx. 12 kg [2.90 gal. approx. 26.5 lbs.]
15 litres, approx. 14 kg [3.96 gal. approx. 30.9 lbs.]
1) The lower limit of the ambient temperature presupposes the pumpability of the lubricant used at the respective actually existing temperature. The maximum admissible
ambient temperature depends on the load and is mainly determined by the runtime and the operating pressure. The stated relative duty cycle refers to lubricants of NLGI 2, an
ambient temperature of 60 °C
[140 °F]
and a medium back pressure of 160 bar on the pump element. In case of temperatures ≥ 60° C and heavy load (higher pressure) the
maximum duty cycle should be reduced. 3) Pumps with UL approval may only be operated up to a maximum permissible ambient temperature of +60 °C, regardless of the load.
2) Pumps with follower plate allow for a rotating installation as well, e. g. in wind turbine generators. Maximum speed and maximum distance to the rotation axis on request. For
pumps without follower plate and expected inclined position (e.g. In case of construction or agricultural machinery) the following applies:
- The maximum filling must be reduced according to the expected inclined position (< MAX marking).
- The minimum filling must be increased as of an expected inclination of > 30 ° (> MIN marking), as otherwise a reduced lubricant volume in the suction area of the pump could
result in a functional impairment.
3) Observe the limits stated in chapter Limits of use of the intermittent low-level indication.
