Grinder product range extended
to handle higher flowrates
The N.Mac twin-shaft grinder is now
available in expanded sizes (photo) for
flowrates up to 400 m³/h. The N.Mac
is designed for breaking down a variety
of different materials and is ideal
for wastewater treatment, biogas and
biomass plants, food processing and
many other waste-handling and industrial
applications. The N.Mac can
be installed upstream of a pump (inline
version) or above the feeding screw of
a hopper pump (channel version) or in
any effluent channel. The inline version
of the N.Mac is available in three sizes
and can handle a maximum flowrate
of up to 350 m³/h. The channel version
of this grinder is available in four sizes,
designed for a maximum flowrate of
up to 400 m³/h. For applications with
even higher flowrates, several grinders
can be run in parallel, additionally allowing
parts of the system to be serviced
during operation. Installation of several
grinders in sequence allows a gradual
reduction of the particle size. The N.Mac
is equipped with flushed and lubricated
mechanical seals for dry-running capability.

Measure oxygen in processes
with this durable device
The Transic100LP oxygen transmitter
(photo) uses tunable diode laser
spectroscopy (TLDS) for repeatable
and drift-free measurements, independent
of process or sample gas
flow, temperature and pressure. The
device has no moving parts, and its
optical components demonstrate
durability, even when faced with
liquid or dust incursions. The Transic100LP
oxygen analyzer can be
installed as a standalone in-situ analyzer,
or as part of a close-coupled
extractive measurement system.
In-situ installations provide rapid response
times and require no sample
extraction or transport components
for greater simplicity. Designed for
in-process measurement, the optical
probe is made of stainless steel
with magnesium fluoride and quartz
lenses for long-term durability. -

More membrane surface area in
a smaller footprint
The newest addition to this company's
X-Flow line of membrane elements,
the X-Flow XF75 ultrafiltration (UF) element
(photo), can be implemented into
both new and existing water-treatment
projects. Although the outer dimensions
are the same as those of existing
X-Flow membrane elements with
membrane areas of 55 and 64 m2, this
company has redesigned the internal
workings and used modified materials
to create extra membrane surface
area. This latest update provides key
advantages in terms of surface area in
relation to element size. By maintaining
the existing element outer dimensions
and increasing the total surface area
to 75 m2, users can take advantage of
more membrane surface area per unit
of weight or volume than the average
of similar UF technologies available
today, says the company. - Pentair

A new range of pumps for
laboratory use
This company has introduced three
new models to its Laboport series of
laboratory pumps - the N 96, N 820
G and N 840 G (photo). These new
diaphragm pumps expand upon the
Laboport pump design with oil-free,
non-contaminating, chemically resistant
construction, as well as speedcontrolled
d.c. motors for greater versatility.
N 820 G and N 840 G models
include an integrated gas-ballast valve
to facilitate short process times, even
for high-boiling solvents. The smooth,
rounded surfaces of all three pumps
enable thorough cleaning. Compared
to similar pumps, these new models
are said to offer a 10-20% footprint
reduction to and a 5-30% weight reduction
for improved portability. The
two larger pumps are expandable into
custom vacuum systems by connecting
an optional separator or condenser
module. Maximum flowrates for the
new series range from 7-34 L/min. Applications
include rotary evaporation,
degassing, filtration, fluid aspiration, gel
drying, centrifugal concentration, vacuum
ovens and more. - KNF Neuberger,
