New 4,000-bar direct-drive pump
WITH a 4,000 bar operating pressure yet
low energy consumption, the newWoma
EcoJet 70M 4000/4 is a cost-saving,
ultra-high pressure, direct-drive pump
for waterjet cutting system operators. Its
compact dimensions mean that the unit
with its plunger pump is easily installed
in new or existing systems. The EcoJet
70M 4000/4’s plunger pump uses very
little oil and runs very quietly, with a
noise rating of just 80 dBA. The direct
drive uses up to 30 per cent less energy.
These are significant improvements on
the performance of pressure intensifier
units. The EcoJet is suitable for abrasive
and pure water cutting and can also be
retrofitted into waterjet cutting systems
for metal, stone and plastics.
Waterjet cutting uses a very fine jet
with an optimal combination of pressure,
water quantity and nozzle. The jet can
cut at a very high speed, producing
an edge-free cross-section and few
shavings. Multilayer material can also be
cut without problems and is not crushed
in the process. Furthermore, the EcoJet
is barely heated with the use of water, so
the process is also suitable for use with
heat-sensitive materials that would melt
or change in shape if they were sawn.

Bending
tools
BEND Tooling Inc has supplied
companies around the world with tube-
bending tooling since 1986. It produces
die sets, mandrels, and wipers for rotary-
draw tube-bending machines for most
makes and models. The company states
that the precision machining of its tooling
eliminates hand-working, improves
quality and shortens lead times.
The company also develops modern
insertedmandrels and wipers. Its inserted
designs are claimed to be favoured by
production tube-bending operations in
the automotive, sports vehicle, HVAC
and hydroforming industries, and are
widely used by speciality tube-bending
companies because of their consistency
in specification, which facilitates frequent
changes in setup.
