The latest generation
dry claw vacuum pump
Introduced early last year, the
nEDC300 dry claw vacuum pump
(photo) boasts a range of inventive
attributes that not only boost
performance,
but
also
minimize
Nidec Motor
noise levels, improve reliability and
facilitate on-site maintenance. This
means that it can be used in a
wide range of applications, such as
water and wastewater treatment,
thermoforming, vacuum conveying,
food processing or even in medical
systems. In these processes, the
dry claw pump guarantees its users
a reliable, cost-effective operation
with easy maintenance options. In
addition to its modular design, a
separate, insulated pump element
makes the inside of the pump easily
accessible to users for maintenance,
repairs and cleaning. This
means that the nEDC claw pump
can be cleaned quickly and easily
by the user. - Edwards Ltd.,

Enhanced line of vertical-pump
motors for severe duty
This company has expanded its
line of Totally Enclosed Fan Cooled
(TEFC) vertical motors, with a new
medium-high thrust motor (photo,
p. 18). This U.S. Motors products
are available
in frame sizes 182
through 286 and are engineered for
use in
severe-duty environments.

The motors drive pumps that are
used in many different industries,
such as water and wastewater, petrochemical,
power and mining. They
feature improved conduit box sealing,
cast-iron frame, brackets and
fan cover guard, and through-thebearing
lubrication for better expelling
of used grease, which extends
motor life and is particularly critical
for vertical motors. The motors also
include an option to meet API 610
driver requirements. - Nidec Motor

These HDD pumps feature an
enhanced fluid-end design
The GD 800HDD pump (photo) is a
compact, lightweight pump featuring
an extremely high rod load and
delivers a flowrate of over 1,000
gal/min. The new fluid-end design
employs the company's patented
Falcon retaining technology, which
makes it easier to service and
maintain the pump. This design accelerates
valve changeout time by
more than fivefold, resulting in reduced
maintenance downtime during
operations. In addition, costly
third-party replacement parts that
accompanied the previous " cagestyle "
valve design are eliminated,
which enables improved operational
efficiencies and streamlined
procurement. All of the GD 800HDD
pumps, which serve a wide variety
of horizontal directional drilling
(HDD) applications, will now utilize
the new fluid-end technology. -

These diaphragm pumps are
designed for chemical service
The tim CHEM double-diaphragm
pumps (photo) are equipped with
a plastic housing of either polyethylene
(PE) or - for high chemical
resistance - polytetrafluoroethylene
(PTFE). Instead of the common
practice of using threaded sleeves
that are screwed into the plastic
housing, this company uses a design
that connects the highly-resistant
plastic components that are in
contact with media by means of tie
rods. The force exerted by the tie
rods is distributed by the large-area
reinforcement plates - a measure
that
significantly minimizes deformation
of the plastic caused by temperature
variations. The company's
tim FIX system uniformly distributes
the forces of the tie rods and minimizes
plastic deformation, and thus
reduces the possibility of leaks.
The pumps have only four sealing
