Operating
Principle:
Each machine is a complete,
mobile, purpose-built, straining unit
requiring only connection of its fluid
lines and to a power source.
Primarily the unit consists of a filter
body which houses two, vertical,
perforated strainer plates. Between
these a monofilament strainer mesh is
sandwiched. The liquid to be strained is
introduced to the strainer body either
by gravity feed from an overhead tank or
by suction pump from a ground level vat.
Once introduced, the material is sucked
through the mesh by an output pump. A
small quantity of the cleaned output is
returned to the rear of the body to an
intense and unique self-cleaning or
back-flushing action which ensures the
mesh remains permanently clear and free
from blockage. An output valve simply
provides an infinitely variable
throughput as desired, and a sludge
valve enables the removal of unwanted
contaminants at periodic intervals
depending upon the liquid being treated.
When the JENAG strainer is fed by a pump
from a ground-level vessel, a bypass is
provided from the input side of the unit
back to the vat. This allows the output
valve to be closed, in this or the
gravity feed mode, without the need to
switch off the strainer itself.
Advantages:
Continuous Operation:
The JENAG Series 1800 and 3000 strainers
are particularly suitable for
high-volume, continuous-flow operations
with outputs up to 6000 litres per hour
and 12000 litres per hour respectively.
Once set up to provide the required flow
rates of output and backwash, they can
operate continuously without further
supervision. Sludge may be dropped from
the machine at the end of the working
shift or even whilst the machine is in
operation, should this be necessary.
The units may be connected directly to a
weight operated filling machine for
automatic operation. Once connected the
output from the JENAG strainer will be
automatically controlled by the demand
of the filling machine itself.
Cost Effective: The
JENAG heart of the strainer is a
monofilament mesh which is selected to
give the required quality of straining.
This mesh, being enclosed within the
strainer body, is protected from
mechanical damage and is kept clean by
the self-cleaning action of the unit. As
a consequence, the mesh has a long life
and may be used over and over again. The
unit price of the mesh is low an is
therefore cost effective.
The only other parts subject to wear
within the body itself are two seals.
These are designed for long life and are
low cost items.
Change over from one product to another
can be effected rapidly and with little
product loss, which allows high
effective utilization of the unit.
Overall the unit is cost effective and
compares very favorably with other
systems or the use of filter bags or
cartridges.
MANY CHOICES FOR VARIED
PROCESSES:
To allow for handling a wide variety of
products strainers can be provided to a
choice of specifications.
Materials of Construction:
Standard supply is with the strainer
body in aluminum but hard-anodized
aluminum, gun-metal or stainless steel
strainer bodies are available.
Pumps: These may be
rotary, helical or double diaphragm to
suit the product and application.
Feed System: By
gravity, when the unit will be fitted
with an output pump only or suitable for
gravity or suction feeding when an input
pump will be fitted as an integral unit.
Electrical Enclosure:
Normally build to EEx d or EEx e
standards as required. Alternatives are
available to meet other requirements. |
