Multi-diaphragm dosing pump is
virtually maintenance-free
The Chem-Feed CD1 (photo) is engineered
to ensure almost no maintenance
requirement for the life of the
pump. CD1 is suitable for dosing with
gas-forming chemicals, such as peracetic
acid or sodium hypochlorite.
The CD1 Dual Diaphragm Hyperlink
Drive Technology pumps chemicals
continuously, is self-priming and will
not vapor lock. Engineered for zero
maintenance, the CD1 includes the
patented ultra-durable diaphragm,
called DiaFlex, which is an exclusive
single-layer diaphragm designed to
last the life of the pump. The CD1 has
a dosing rate of up to 7.70 gal/h (29.2
L/h) and is easy to install and operate.

An efficient cleaning system
for mixers
Maag Pump Systems
WIKA Alexander Wiegand
Automatic WIP-Systems (photo) provide
a reliable and repeatable process
for cleaning mixing systems - such
as the Ploughshare Mixers - an important
task especially in life-science
applications. A smart arrangement
of rotating cleaning nozzles inside
the mixing drum ensures a thorough
rinsing of all product contact surfaces
without any need for filling the machine
with cleaning media. By simultaneous
rotation of mixing elements
and cleaning nozzles, any spray shadows
are avoided. The gear-driven rotating
flat fan nozzles guarantee an
intensive and uniform cleaning of all
surfaces. Besides the rotating cleaning
nozzles inside the mixing drum,
the seals for the mixing elements and
choppers are purged with water and
all ports on the machine are cleaned
effectively by static, locally installed
cleaning nozzles. - Lödige Process

A polymer pelletizer for when
capacities are high
R. Stahl

The Pearlo 350 EAC underwater pelletizing
system (photo) has a liquidheated
die plate for high capacities,
delivering throughputs of 18,000 kg/h
of virgin polymer. The unique cuttingblade
design and optimum water- and
material-flow
conditions within
the
cutting chamber provide not only ideal
and homogeneous cooling effects, but
also outstanding pellet quality, says
the company. Another design feature
is the cutting-blade advance system,
which permits axial movement of the
cutter shaft,
resulting in a precise
blade advance, as well as a regrinding
of the blades during production.
This allows higher equipment availability
and lengthened production runs,
which saves costs. - Maag Pump

A compact pressure gage
system for emission control
The new Emission Control Gauge
(EMICOgauge; photo) pressure-measuring
system features the assembly
of a model 2xx.30 pressure gage in
a safety version in accordance with
EN 837-1 (S3) and a valve to prevent
fugitive emissions. An easily rotating
adapter with a special sealing packing
connects the measuring instrument
and the valve. The system is fully
leak-tested in accordance with the requirements
of TA Luft (VDI 2440) for
fugitive emissions. The EMICOgauge
measures pressures from 0 to 420
bars. In the event of a fault due to
high overpressure, the S-3 safety version
protects the user from injury. The
freely rotating swivel adapter allows
360-deg positioning of the display
and easy dismounting of the measuring
instrument for calibration. - WIKA

Compact relay modules for use
in hazardous areas
Two new relay modules have been
added to this company's product
range for hazardous areas in Zone 1.
The series 9174 and 9177 (photo) relay
modules enable a.c. and d.c. loads to
be switched using the Ex e and Ex i
types of protection. The compact devices
are just 12 mm wide, and only
require a suitable field enclosure made
of plastic or thin-walled stainless steel.
The 9177 enables galvanically isolated
switching of intrinsically safe (Ex i) and
non-intrinsically safe (Ex e) electrical circuits
using an electromechanical relay.
