3. Overview, functional description 3. Overview, functional description Overview Fig. 1 1 Reservoir The lubricant is stored in the reservoir. De- pending on the pump version there are differ- ent types of reservoirs and reservoir sizes. 1.1 Reservoir venting device It provides air for the reservoir while the pump is operating and supplying lubricant.

3. Overview, functional description Overview Fig. 2 4 Pump elements The pump can be operated with up to 3 pump elements, 5 Filler fitting It serves to fill the reservoir via a suitable filler pump with a corresponding connection. 6 Electrical connections They serve for (6.1) signal connection (X4), for (6.2) power supply connection (X2) and for connection of the low-level indication (6.3) in...

3. Overview, functional description Overview Fig. 3 7 ProProtect indication If the LED (7) is green, the ProProtect protec- tion up to 8 kV is available. If the LED (7) is off despite existing operating voltage, only the standard protection level (EN 61000-6-4) is available.
Page 24
3. Overview, functional description Overview Fig. 4 8 Follower plate (in case of pumps with fol- lower plate) The follower plate (8) rests on the lubricant and presses it down in the direction of the pump elements by spring force. As a result the suction behaviour of the pump improves.
3. Overview, functional description 3.1 Functioning principle of the intermittent low-level indication The intermittent low-level indication operates free of contact. Its main components are the following: ○ firmly positioned magnetic switch (I) inside of the reservoir bottom ○ flexible guide plate (II) connected to the stirring paddle with a magnet (III) and a control cam (IV) If the reservoir is filled with a lubrication grease suitable for the intermittent low-level indication and the pump is operating, then the guide plate (II) is de- flected by the resistance of the lubrication grease.
4. Technical data 4. Technical data 4.1 Mechanics P623M 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.
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.
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 1, 2, 3) of the lu- bricant to be used and the operating temperature. 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.
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.
4. Technical data 4.6 Tightening torques The stated tightening torques must be adhered to. Pump with supporting construction provided by the customer 25 Nm ± 1,0 Nm Pump element with pump housing 40 Nm ± 2.0 Nm Pressure control valve with pump element 08 Nm + 0.8 Nm Housing front cover with pump housing 2.5 Nm + 0.1 Nm...

4. Technical data 4.8 Processing of the low-level signals in case of external controller and monitoring of the pump To avoid early low-level indication (e.g. caused by air inclusions or wave formation in the lubricant) in case of external controller or monitoring the following conditions have to be fulfilled by programming the external controller accordingly.
