out dynamic seals, providing leak-free
pumping for difficult-to-seal, expensive,
valuable, dangerous and hazardous
liquids. With this rotary-vane
magnetic-drive pump design, these
pumps combine the leak-free benefits
of a magnetic-drive pump with the
numerous advantages of sliding-vane
technology, including self-priming,
line-stripping, product recovery, indefinite
dry-run capability, solids handling,
and more. The pumps are available
in a 3-in. model (a 4-in. model will
be available in January 2021) in both
ductile iron and stainless-steel construction

Introducing four new
vacuum/compressor pumps
The new N 630 diaphragm vacuum/
compressor pump series (photo) delivers
high pressure and gas tightness
with a durable, long-life design. Four
versions are available for use in industrial
coolant systems, gas recycling,
gas and emissions measurement and
analysis and leak detection across a
wide variety of industries. The pumps
have a long service life and generate
vacuum down to 0.74 in. Hg (25 mbar
abs), positive pressure up to 174 psig
(12 bars rel.), and deliver a flowrate up
to 2.4 ft3/min (68 L/min). The costefficient
and reliable diaphragm gas
pumps are available in four variants:
either one- or two-headed and connected
in series or parallel, as a vacuum
pump, or as a compressor. All
models come with long-lasting EPDM
or chemically resistant PTFE-coated
diaphragms for exceptional durability
and service life. - KNF Neuberger,

Two new compact vacuum
pumps that are energy-effi cient
This company has expanded its Ecodry
plus product family of dry, multi-stage
Roots vacuum pumps for laboratory,
research and development and analytical
applications. The current Ecodry 40
and 65 plus models are now joined by
the new, smaller pump sizes Ecodry 25
and 35 plus. This completes the company's
range of quiet, low-maintenance
and economical fore-vacuum pumps
and fills the gap between Scrollvac 18
plus and Ecodry 40 plus. Thanks to
18
technical optimizations, the vacuum
pumps are smaller and more energyefficient
than competitive products,
says the company. The oil-free multistage
Roots pumps Ecodry 25 and 35
plus also have a maintenance interval
of five years, during which time they
run without any servicing. - Leybold

A digital tool for
confi guring a dosing system
The Dosing Skid Configurator (photo)
is an interactive digital tool featuring
thousands of configuration variants
to serve an array of applications with
complete chemical dosing solutions.
By answering a few simple way-ofuse
questions to configure the best
solution, the Dosing Skid Configurator
generates an interactive 3-D model
of a pre-engineered dosing skid system
- one of 16,000 possible configuration
variants - a materials list,
dimension drawings, list pricing, a
downloadable submittal package and
a contact form to reach a distributor
to learn about ordering and availability.
Potential applications include dosing
skid systems for water treatment,
peracetic acid (PAA) dosing for food
and beverage facilities, and so on. -

Inject up to four wellheads with
a single pump
This company has launched a multipoint
injection controller adjustment for
its Texsteam pumps (photo). Texsteam
multipoint injection will be used in oiland-gas
wellhead chemical-injection
operations to distribute chemicals
from a single chemical-injection pump
to multiple injection points. This lowers
capital spend by reducing the amount
of equipment required for chemical injection.
Instead of needing four pumps
for four different wellheads, the operator
will now be able to inject four
wellheads with just one pump, says
the company. The Texsteam multipoint
injection system works up to a
maximum operating pressure of 2,500
psi, with the solenoid assembly requiring
only 10 W of power consumption.
