Upgrade to Valve Seat Area of HDF2 Pump from Kelair Pumps Australia
Product News
Sales Engineer Myro Bratkovic (QLD)
Warren Rupp has recently
announced the evolution of
its Sandpiper 50mm heavy
duty flap valve pump
(commonly known as the
HDF2) to Design Level 6.
The engineers at Warren
Rupp have applied upgrades
to the valve seat
area of the HDF2 pump.
These changes include the
introduction of a heavy
duty flap valve seat in
stainless steel now fitted
with an integral "o-ring"
type seal. This new configuration
replaces a
stamped flat stainless steel
seat that required two
separate gaskets on each
seat. The pump suction
and discharge elbows are
now also fixed to the chambers
by hex head screws,
replacing stud bolts and
nuts.
So what is the benefit to
the user for these modifications
to the HDF2 pump?
By changing to an engineered
seat with integral oring
fitted means that the
pump can be overhauled
without the need to break
and replace gaskets. This
evolution means that at
each flap check valve on
the pump, one item now
replaces 3 separate components
- one seat and
two gaskets.
Replacing the studs and
nuts with hex head screws
means that the number of
these hardware components
has been halved.
The real benefit to the user
is that the change to the
new heavy duty flap valve
will result in longer pump
life and reduced operating
cost due to there being
fewer replacement parts,
lower maintenance costs
and reduced downtime.
What's more, any existing
older model SA2 and HDF2
design level 5 pumps can
be upgraded by simply installing
the new design flap
valve seat assembly.
The seats are available
with o-ring materials in
Buna-N, EPDM, Viton and
Neoprene to handle many
different applications and
liquids.
