    4. Technical data 4. Technical data 4.1 Mechanics P623S Admissible operating temperature range of the pump -25 °C to +55 °C The indicated operating temperature range of the pump presupposes the suitability of the lubricant used for the respective actually existing operat- ing temperature.

  • Page 33: Nominal Output Volumes

    4. Technical data 4.2 Nominal output volumes Pump element Nominal output per pump element and stroke 0.22 cc The stated nominal outputs per stroke refer to NLGI II lubricating greases at an operating temperature of + 20 °C and a backpressure of 100 bar on the pump element.

  • Page 34: Useable Reservoir Volume

    4. Technical data 4.3 Useable reservoir volume Regarding the reservoir version without follower plate the useable reservoir volume mainly depends on the NLGI consistency class and the operat- ing temperature of the lubricant to be used. In case of high consistency and low operating temperature normally more lubricant sticks to the inner surfaces of the reservoir and the pump and is thus no more available for being dispensed.

  • Page 35: Limits Of Use Of The Intermittent Low-Level Indication

    4. Technical data 4.5 Limits of use of the intermittent low-level indication The following lubricant consistencies have to be complied with in order to ensure the correct functioning of the intermittent low-level indication. Above the stated range of temperature a correct functioning of the intermittent low-level indication cannot be ensured. The inferior temperature ranges require the suitability of the lubricant for the respective temperature range.
