Sandpiper Pumps for Filter Press Applications by Kelair Pumps Australia
Case Study
Sales Engineer Cory Jessop (WA)
Sandpipers press on
A filter press is very basic, but
very effective and important in
a lot of process applications
and Sandpiper pumps play a
major role for many of Kelair's
customers.
A filter press is used for separating
solids from liquid slurries.
This is known as compressed
cake.
Sandpiper pumps can handle a vast
range of products and product
viscosities making them ideal
for filter press application.
A filter press consists of a series
of horizontally arranged vertical filter plates, each covered with paper, felt medium or synthetic woven material. A mechanical structure
(skeleton) is used to support the filter plates and a closure
mechanism provides the required force on the sealing faces of the plates to counteract the applied force of filtration(squeezing).
The presses work on what is
known as feed pressure or
squeeze pressure. This reduces
the liquid content in
waste slurries or the solid content
in industry processes.
One of the main benefits of
Sandpiper AODDPs is that the
maximum pump pressure will
never exceed air inlet pressure
and a consistent pumping
rate can be maintained
even under fluctuating pressure
head conditions.
Sandpiper AODDPs are also
extremely versatile in handling
the different flow and pressure
which will differ continuously
with this application,
another reason they are so
ideal.
Filter press systems often
become blocked due to the
viscosities of the liquid being
pumped, causing the pump to
run dry. Sandpipers have the
capability to run dry indefinitely without causing any
damage to the pump and they
are also completely selfpriming
from a dry-start on
suction lifts.
Because of their simple design,
Sandpiper pumps have
no shaft seals or packing
glands which can wear and
require frequent maintenance.
With no rotor, impellers, gears,
vanes or pistons to wear out,
the user can be confident that
pumping efficiency will not
deteriorate over time.
The customer has had the
same Sandpiper pumps on
their filter presses for the last
five years and has only just
requested a replacement for
one of four at the plant. The
pumps play a huge role at very
little cost in the customer's
business.
