A new calculator tool for
selecting vacuum pumps
A new vacuum-calculation tool
(photo) is now available to identify
specific vacuum products for various
applications. The calculator provides
evacuation and pump-down
curves for different pump technologies
and also performs different calculations
for self-configured pumping
solutions. Users simply input the
technical parameters in order to find
matching products, and to compare
different vacuum solutions. The vacuum
calculator can be used via the
company's website, which also provides
videos describing how to use
the tool. - Pfeiffer Vacuum GmbH,

Inlet traps help prevent
premature pump failure
PosiTrap vacuum-inlet traps (photo)
feature a fully positive seal at both
ends to prevent contaminants from
entering the pump, potentially causing
premature failure. The traps come
in sizes of 4 and 8 in. for pumps with
capacities of up to 25 and 50 ft3/min,
respectively.
Made of stainless steel
with straight-through and right-angle
ports and flange sizes from NW 25
up to ISO 80, they can be supplied
with a wide variety of filter elements.
Designed to protect pumps from
particulate matter, organic solvents,
hydrogen peroxide, acids and water
vapor, filter media offered for PosiTrap
traps include stainless-steel mesh,
activated charcoal, molecular sieve,
polypro and Sodasorb. - Mass-Vac,

A new pump brand for
biotechnology applications
This new brand brings together its
parent-company's pumping, flowmeasurement
and flow-metering
technologies (photo, p. 20). Included
in this new brand are the Quaternary
(four-piston) Diaphragm Pumps,
which are suitable for transferring
shear-sensitive aqueous solutions and
biological materials, while being cleanin-place
(CIP) and sterilize-in-place
(SIP) capable. The single-use models

THE NEXT GENERATION OF DEWATERING
AND DRYING SOLUTIONS
EFFICIENT SEPARATION SOLUTIONS THAT FOSTER GREEN CHEMISTRY
Chemistry, particularly specialty
chemicals, will likely play a crucial
role in addressing challenges like
global warming, climate change, and
population growth. This industry offers
a wide range of materials that can help
conserve resources, reduce waste, and
boost efficiency. Specialty chemical
producers aim to reduce greenhouse
gas emissions, increase energy efficiency,
and promote renewable energy. And it is
precisely for this purpose that ANDRITZ
supplies most efficient solutions in the
field of separation. Our current portfolio
includes various dewatering and drying
solutions - such as decanter and pusher
centrifuges, paddle, plate, helix and
fluid bed dryers, and many more - and
we are constantly developing and
testing new solutions in our pilot plants
