The constantly growing demand for their hydraulic
components meant that Hydraforce recently had to
expand its manufacturing capacities. This also
involved the investment in a new cleaning system
from MecWash. “The new system should firstly be
capable of cleaning a very large number of
components both quickly and efficiently. However, it
must also be able to reliably work to stricter
cleanliness requirements than we generally see
today,” reports John Pattison, Director at MecWash.
The soiling to be removed comprises swarf, oil and
cooling lubricant residues, as well as brazing residue.
Faster and cleaner thanks to
twin-frequency ultrasonic output
The system manufacturer designed a single-
chamber cleaning unit for this task which
employs an aqueous medium. Depending on the
component, cleaning is performed as set parts or
goods in bulk. To cater to both the quantitative and
qualitative requirements, the new system employs
twin-frequency ultrasonic output. In terms of the
ultrasonic components, MecWash went with

impressed by the technical expertise of their
employees. Last but not least, their service is always
available quickly when we need it,” comments John
Pattison, explaining the reasons why MecWash
decided to go with the component manufacturer
from Karlsbad in Southern Germany.
Two Sonopush Mono HD rod transducers, each with
25 kHz (1,500 W) and 40 kHz (1,200 W) output,
are integrated into the system’s chamber. These
patented Heavy Duty rod transducers can be used
up to temperatures of 95°C and also work reliably
in 24-hour continuous operation. They therefore
meet the strictest cleanliness requirements with
shorter cleaning cycles and greater throughput. The
ultrasonic solution is rounded off by power-adjusted
Sonic Digital HS2 generators. On the system
component, designed as an integrable, top hat
rail-compatible unit, the power output can be
controlled in the range from 50 to 100 percent in
1% steps. This facilitates optimum matching to
parts-specific cleaning programmes.
