Decanter centrifuges tailored to
industrial oil recovery
Andritz
Tsurumi America
This company has enhanced its range
of three-phase decanter centrifuges
(photo) for oil recovery in the most challenging
industrial applications. These
three-phase decanter centrifuges are
not only capable of separating liquids
from solids, but also liquids with different
densities, like oil and water. These
proven machines have now been further
developed and tailored for the
recovery of high-purity oil from tainted
sources, such as slop and crude oil,
lake, lagoon or tank cleaning runoff
and API separator sludge. Crucially for
oil-and-gas applications, the decanter
centrifuge range includes both ATEX
Zone 1 and Zone 2 machines. This
makes them suitable for use in plants
where an explosive atmosphere may
occur during normal operations. Machine
housing seals can be supplied as
gas-tight, flame- and explosion-proof
versions up to P < 1.5 bars(abs) featuring
a labyrinth seal system with three
or more rings. Zone 1 versions have
a design capacity of up to 12 m3/h,
while Zone 2 designs can achieve flowrates
of up to 40 m3/h. - Andritz, AG,

These agitator pumps are
designed for wear resistance
This company's agitator pumps (photo)
are manufactured with wear-resistant
components like high-chrome impellers
and hard cast-iron volutes that
demonstrate durability and efficiency
when handling abrasive materials in
applications that involve sand, grit or
other debris. Agitator pumps utilize an
agitator propeller that shares the same
shaft as the pump's impeller. While the
two spin in the same direction, the
agitator blades are in the opposing orientation
to those of the impeller. The
agitator provides a propelling force to
stir up solids near the floor, while the
impeller pumps the now-suspended
solids along with the fluid. They keep
the mud circulating to avoid solids from
settling while allowing pumping to continue
without obstructions. A potted
cable provides an extra layer of protection
in case of accidental nicking
of the exterior cable. This protection
prevents moisture infiltration and, ultimately,
motor failure. Using the rotation
of the shaft, the oil lifter spins and flings
oil throughout the seal chamber. This
provides lubrication and cooling of the
seal faces down to one-third of normal
oil level without the need for additional
power or external equipment. A builtin
thermal-protection component prevents
motor failure due to overloading
and accidental dry-running. - Tsurumi

These new check valves
can be flexibly installed
The ES Series of spring check valves
(photo) feature a PTFE-covered, stainless-steel
spring for positive closing, as
well as a new disc design for smooth,
trouble-free operation. Compared to
ball check valves, the ES Series requires
very low liquid-head pressure
to close. That means more flexibility
as to where valves may be placed in
a piping system. Features include high
corrosion resistance, smooth troublefree
operation and easy installation
and maintenance. ES Series valves are
available in sizes ranging from 0.5 to
3 in. End-connection options include
socket, threaded, flanged or this company's
ChemFlare fitting technology.

Hygienic counting machines
for food products
The WD Series (photo) is a new
counting system designed for precise
counting and dispensing of individual
food products in a variety of applications
where cleanliness is paramount,
including poultry, meat, seafood,
cheese, confectionary and bread products.
WD Series machines are scalable
for varying production levels. Compatible
with all industrial packaging machines,
highlights include a compact
footprint, FDA-compliant product parts
for processing both food and non-food
products and streamlined tool-free
disassembly. Other features include a
product-detection unit with 100% reported
accuracy, hinged side panels
for optimal cleanability and vibratory
plates for product transport and separation.
