GENERAL DESCRIPTION
The
G025
hydraulically actuated grease pump is used to lubricate the 2,500 to 15,000
ft. lb. class NPK hydraulic hammers. Due to its compact design, it can be mounted
directly to the hammer upper support block.
The NPK hammer mounted auto lube system is connected to the hydraulic system of
the carrier unit via the pressure line (
6
) of the hammer to port P
OIL
(
126
) of the lube
pump housing (a59).
The hydraulic oil is routed via a filter/diaphragm (a57) to the hydraulic motor (a58),
which ensures continuous drive. The hydraulic oil is returned to the circuit via the
hammer return line (
5
), or port R
OIL
(
127
) on the lube pump housing.
