Pump selection
The number of hydraulic pumps that feed the hydraulic system can be
selected: selector D6 allows choosing 1 or 2 pumps.
By varying the capacity, the rotary head basic speed also varies:
•
for normal foundation drilling operations two pumps are used;
•
the use of a single pump slows down the rotary head speed
considerably, thereby making it more suitable for compacted soil with
rock formations (pointed buckets);
•
the use of a single pump simplifies some rotary head rotation
simultaneous controls (e.g. mast lifting and rotation)
•
in CFA mode, is recommended to work with only one pump.
