ciency can be compared with the performance
of closed multi-channel impellers,
the company says. The D-max
impellers are used in the Sewatec and
Amarex KRT pump type series. The
maximum head is approximately 90 m
and the maximum flowrate is approximately
2,800 m3/h. - KSB SE & Co.

New lobe pumps for a
wide variety of fluids
The new LPX lobe pumps (photo)
are designed to meet the growing
demand for high-performance and
reliable flow solutions in various industries,
including food and beverage,
pharmaceutical, chemical and
wastewater treatment. The LPX lobe
pumps are suitable for handling a
wide variety of fluids, including those
with high viscosity, such as syrups,
creams and pastes. These pumps are
also highly efficient, with low pulsation
and shear, making them ideal for delicate
fluids that require gentle handling.
The pumps are available in a variety of
sizes and materials, including stainless
steel, and they are easy to install
and maintain, with minimal downtime
required for servicing or repairs. -

A dosing pump with more
features, better performance
The vipro-PUMP series (photo) features
a new design, optimized dosing
components and modular construction,
making it possible to adapt the
dosing equipment to the application.
The core of this new generation is the
modular design of the dispenser. The
separable rotor assembly allows fast
installation and removal of its components,
while variable rotor and stator
materials ensure optimum dispenser
performance. For example, a ceramic
rotor with matching stator is suitable
for abrasive media, while an HVC
rotor is used for standard applications,
such as adhesives. An enlarged
pump inlet minimizes pressure loss,
improves the material flow and allows
easy attachment and detachment of
the hose supply. The new stator design
has an anti-rotation device and
a defined non-positive connection
to allow easy and intuitive assembly.
Various drives can be attached
to the dispenser using a locking ring
and a newly designed coupling. -
New drive system for
diaphragm metering pumps
This company's ecodos series of diaphragm
pumps (photo) now include a
new form of wide-range speed control.
Alongside asynchronous motors
and servomotors, permanent-magnet
synchronous motors (PMSMs), are
also used now. They are characterized
by high energy efficiency and a
control range greater than 1:200. This
significantly expands the range of applications.
With PMSMs, it is no longer
necessary to use several pumps for
different flowrates or oversize asynchronous
motors for low speeds.
Since PMSMs can be designed without
a fan, they are compact and easy
to clean, which makes them suitable
for hygienic applications. All materials
in contact with the fluids used in the
pump units meet FDA and USP Class
VI requirements, and the E.U. directives
for the food industry. High efficiency
rating over the complete control
range, in accordance with energy
efficiency class IE5+, also reduces energy
costs, thus ensuring a lower total
cost of ownership. - LEWA GmbH,

Consider flow conditioners
when space is limited
The efficiency and service life of
pumps can be greatly extended by following
the manufacturer's installation
recommendation for pipe straight run
entering the pump. When cramped
pump houses or restricted pipe runs
make this impractical and costly, this
company's flow conditioners can be
used to deliver a uniform, swirl-free
flow profile to the pump inlet in as little
as three pipe diameters. The simple,
flexible designs of the Model VEL
elbow (photo) and the Model VIS insertion
sleeve configurations provide a
cost-effective, easy-to-install solution
that supports proper pump installation.
The conditioners can be made
from carbon steel, 316L stainless steel
or Hastelloy C-276 and in almost any
pipe size. A variety of process connections
are also available, such as
ANSI flanges, male NPT threads, buttwelded
preps or retaining wafers. -
