Number of outlets .......................................................... 1,2 or 3
Reservoir capacity ....................................................... 2 l, 4 l , 8 l
Refilling ........................ via hydraulic lubrication fitting or from top
Lubricant .................................. greases of at least NLGI grade 2
mineral oils up to 40mm²/s (cST) at 40° C
Class of protection .........................IP6K 9K acc. to DIN 40050 T9
*Note: The pump is designed for the above mentioned temperature range. The lubricants used must still be pumpable at the
temperatures mentioned above. In case of doubt, consult the
lubricant manufacturer.

Closure plug in housing .................. ..........................................12 Nm
Pump element
Piston diameter, K5 ........................................................... 5 mm
Lubricant output ........................................ approx. 2 cm³/min
Piston diameter, (standard) K6........................................... 6 mm
Lubricant output ...................................... approx. 2.8cm³/min
Piston diameter, K7 ........................................................... 7 mm
Lubricant output ........................................ approx. 4 cm³/min
Max. operating pressure. ................................................ 350 bar

Important! The lubricant output listed refers to grease of NLGI grade
2 measured at 20°C, backpressure 100 bar, nominal voltage 12/24
V. Any differing pressures or temperatures result in different lubricant
outputs. Any system design must be based on the above values.
