Mode of Operation of Pump 233
The electric motor drives the eccentric (1, fig. 7, 8).
During the operating time:
- piston 2 sucks in lubricant from the reservoir, see fig. 7.
- piston 2 dispenses the lubricant to the connected
lubrication points via the metering devices, see fig. 8.
The following designs are available:
Piston diameter, K5 ..................................................... 5 mm
Lubricant output....................................... approx. 2 cm³/min
Piston diameter, K6 (Standard) .................................. 6 mm
Lubricant output.................................... approx. 2.8 cm³/min
Piston diameter, K7 ..................................................... 7 mm
Lubricant output....................................... approx. 4 cm³/min
Tightening torque............................................25 Nm
