Versatility
BlackStone pumps have been designed to
meet the ever changing needs of industry.
With their broad, !at base and mounting
holes for tank, shelf or !oor mounting
(horizontal), the pumps can be easily mounted
anywhere in your plant. The rear of the
pump housing also provides mounting holes
to facilitate vertical mounting: wall, tank or
machine. Since the pump valve assembly
and controls for the unit are located on the
front of the pump, there is never a problem
with installation or !ow adjustments.
Simple Operation
BlackStone pumps are equipped with a single
control for pump output. The external !ow
rate control (potentiometer) on the face of
the pump allows you to adjust the percentage
of !ow from 0 to 100% of the pump’s rated
capacity. This feature eliminates the need
to worry about stroke lengths and power
settings. An LED indicator lights up each
time a stroke begins, allowing the user to
assess the stroke rate from a distance.
High Quality Materials
BlackStone pumps have been manufactured
with the highest level of mechanical precision
from materials chosen for their inherent
ability to resist the e"ects of aggressive
chemicals. When you select a Blackstone
pump, you are eliminating the time consuming
e"ort involved in picking the right material
for your application. Blackstone pumps are
supplied with the highest quality material
as standard equipment—not optional. The
diaphragm utilizes one-piece construction of
PTFE, which unlike conventional laminated
diaphragms, will stand up to the test of time
and wear. Ball valves are constructed in glass.
The pumphead and O-rings are made of PVDF,
PTFE and FPM/FKM which o"er unsurpassed
resistance. The chemical resistance chart
(right) shows how well PVDF and PTFE stand
up to some of the most aggressive chemicals.
