New Products
Introducing a large milldischarge
slurry pump
The MDM900 mill-discharge slurry
pump (photo) is the latest addition to
this company's flagship Mill Discharge
(MD) Pump Series. The MDM900 is
designed for heavy-duty use in concentrator
plants, where capacity and
wear-resistance are essential. The
MDM900 is an all-metal, thick-walled,
extra heavy-duty pump designed for
extremely arduous mill-duty applications.
The advanced design of the
MDM900 enables minimized slurry
velocities in the pumps, thus reducing
the rate of wear significantly. This
translates to increased uptime and
productivity, says the company. The
pump delivers flowrates up to 13,500
m³/h (60,000 gal/min) with heads up
to 40 m (132 ft). Its impeller has a diameter
of 2,100 mm (83 in.) and an
inlet size of 900 mm (36 in.) - Metso

An extractor for valorization of
functional nutrients
The Turbex extractor (photo) helps
to produce high-quality extracts from
botanicals and natural products and
to turn waste, such as orange peel
or brewer's spent grain (BSG), into
revenue-generating nutrients. This
patented extraction technology uses
a series of rotors and stators to cause
thousands of cavitation events per
second, resulting in higher yields in
shorter processing times. Assisted
by a counter-current process, Turbex
delivers yields up to 50% higher than
conventional systems, says the company.
The low extraction temperature
combined with the short processing
time improves the product quality
since oxidization of valuable polyphenols
and antioxidants is avoided.
Requiring up to 30% less energy than
conventional extraction methods,
Turbex is said to have a faster return
on investment and less environmental
impact. - Andritz AG, Graz, Austria

Swing check valves for
fluegas desulfurization
The maintenance-free RSK swing
check valves (photo) offer a high
functional reliability because a tight
shut-off is ensured by a rubber-lined
valve disc without rotating parts
and without extensions through the
body wall. Because all wetted parts
are rubber-lined, they are highly resistant
to corrosion and abrasion,
such as in fluegas-cleaning systems.
The swing check valves are fluidcontrolled,
which means their functionality
cannot be manipulated from
the outside. In low flowrates - that
may occur when operating variable
speed pumps - the valve disc remains
stable in its position and does
not tend to chatter. With their streamlined
design, the flow resistance
of these valves is up to 45% below
that of alternative check-valve types.
The valve can be mounted in either a
horizontal or a vertical position. The
bodies made of nodular cast iron are
available in nominal sizes 25 to 300
and designed for a nominal pressure
of 16 bars. - Sisto Armaturen S.A.,

This silencer helps protect
workers from gas process noise
The Fisher WhisperTube Modal Attenuator
(photo) was introduced
recently for noisy gas or vapor applications.
The modal attenuator is a
full-bore device offering 15-dB sound
suppression to reduce noise inside
pipes produced by sources upstream,
such as control valves, pressure-relief
valves, pumps, compressors
and other devices that generate
noise. It is installed downstream of
these types of devices in place of a
pipe spool piece, generates no additional
pressure drop and has no impact
on process flow. WhisperTube
devices are offered in sizes from 2 to
12 in., with AMSE flange ratings of
Class 150, 300 and 600. Pressure
ratings match the flange rating sizes,
and the maximum temperature is
700°F. - Emerson

This heat exchanger provides
330°F air for drying process
The custom designed three-stage
heat exchanger (photo) will be used
to increase temperature of a 25,000
std. ft3/min airflow from 50°F to
