Dickow Pump
as detection monitors with
integrated pumps or monitors
calibrated in docking
stations with built-in pumping
systems. - Linde Canada

This pump family is designed for
sanitary and hygienic applications
Pro-Flo X Hygienic Series pumps feature
the company's patent-pending Pro-Flo X
Air Distribution System (ADS) and the
Efficiency Management System (EMS).
The ADS provides reliable operation,
high flowrates, and anti-freezing characterisics,
while the EMS allows the user to
control flowrate and efficiency with the
turn of a dial. All polished product-contact
surfaces have a maximum roughness
values (Ra) of 0.8 μm. A flow-through liquid
chamber design and smooth flow path
enhances cleanability and prevents product
entrapment. - Wilden Pump, Grand
Terrace, Calif.

These compact pumps are ideal for
applications with space restrictions
The three-chambered configuration of
the Flojet Triplex Series high-pressure,
self-priming pump operates at flowrates
up to 1.4 gal/min (5.3 L/min) and
operating pressures up to 150 psi (10.3
bar). Their molded diaphragms virtually
eliminate potential leakage paths,
says the company. These pumps can
run dry for extended periods without
damage. - ITT Flojet, SantaAna, Calif.

Seal-less centrifugal pumps keep
potential emissions at bay
The Series NMWR seal-less centrifugal
pumps (photo) have magnetic couplings and
no shaft duct to the atmosphere, and are
available with maximum capacity to 4,000
gal/min and differential head to 500 ft. The
containmment shell forms a closed system
with a hermetically sealed liquid end. They
are designed to handle heat transfer fluids
with temperatures up to 750°F without
cooling. The containment shell provides a
simpler replacement to conventional double-acting
mechanical seals with external
fluid reservoirs, says the firm. - Dickow
Pump Co., Marietta, Ga.

Less pipe straight-run needed
with this flow conditioner
The Model VIP flow conditioner offers
this company's tab-type flowconditioning
technology in a lowcost,
simply installed insertion
panel format. It avoids the need,
as with many flowmeter types,
to have a significant straight run
of pipe to allow a repeatable, swirl-free
flow profile to the sensor. When space
and pipe orientation conditions do not
allow a straight run, the VIP can neutralize
flow disturbance from valves,
elbows and other components when
installed at a distance of three pipe diameters
from the flow meter, allowing
optimum function of the flowmeter. The
thin, lightweight VIP can be installed
between flanges or welded in place. -

New rules in vacuum drying:
The Planex System
The Planex System (photo) is a new
horizontal paddle vacuum dryer developed
for vacuum drying of wet
powders obtained from centrifuge or
filter press. The system consists of a
fixed cylindrical chamber with an eccentric
agitator inside with two independent
movements: it can rotate on
its own axis and tangentially to the
cylindrical chamber as well. This combined
double rotation allows optimal
product mixing, continuously renewing
the surface exposed to evaporation.
As a result, the release of solvent
vapor is facilitated and drying times
are significantly reduced compared to
conventional systems, says the manufacturer.
The unique configuration of
the agitator and the double rotation
provides continuous revolution of the
product while limiting the mechanical
and thermal stress, preventing
local overheating due to friction. The
mechanical stress on the product is
said to be three times less than that
produced in traditional paddle dryers

Italvacuum
equipped with concentric agitators.
This property makes the system ideal
for drying heat-sensitive products,
and also leads to a reduction in power
consumption by about a third. - Italvacuum
S.r.l., Borgaro (Torino), Italy

Eccentric-disk pumps can be used
for abrasive, thick or thin fluids
The Mouvex SLC-Series eccentric-disk
pumps are designed to self-compensate
for mechanical wear and maintain consistent
flow over time. With seal-less construction,
low shear and agitation of the
pumped product, the ability to run dry for
up to five minutes and clean-in-place capabilities,
these pumps enjoy lower maintenance
requirements and lifecycle costs
for the transfer of various liquids. The
eccentric-disk technology produces the
pumping performance of a positive-displacement
pump, creating a constant flow
independent of pressure and viscosity,
says the firm. - Mouvex, Auxerre, France
www.mouvex.com
This pump family has been expanded
to include an engine-driven model
The newest addition to the Ultra V Series
pumps family is an engine-driven
model said to offer higher pressure, flow
and efficiency than comparable pumps.
Shimless adjusting, atmospheric vents
and self-cleaning wear plates ease
maintenance requirements. They are
available in 3-, 4- and 6-in. sizes, and
can handle flows of 2,050 gal/min and
maximum head of 175 ft. - GormanRupp,
