Easy installation
Designed with mounting holes in the base
as well as rear panel, BlackStone pumps
can be installed on a wall as well as directly
on top of tanks and drums.
There is no need for additional hardware.
All the controls and pump assemblies are
conveniently located on the front of the unit.
If the operator must access the pump head
or control panel for any reason, there is no
need to dismount the unit.
FLOW RATE CHART
The following charts show the relationship
between their flow rate and pressure.
An increase of pressure in the system de-
creases the flow rate.

COMMON FEATURES OF BLACKSTONE
PUMPS
High quality materials
BlackStone pumps incorporate Kynar
®
and
Teflon
®
into their diaphragms, hose connec-
tors and pump heads to provide maximum
protection for parts in contact with aggres-
sive chemicals.
The ball valves are constructed in glass.
The body is made of fiber-reinforced polypro-
pylene for strength and durability.
Reliability through simplicity
All BlackStone pumps use the positive dis-
placement solenoid method of pumping. This
method has fewer moving parts than a stan-
dard motor-driven pump, and does not have
the mechanical failures associated with con-
ventional pumps.
BlackStone's Positive Displacement design
has several distinct advantages over other
types of mechanical designs:
• It is more accurate. Each stroke of the
piston is precisely the same as the stroke
before it ... and the stroke after it.
• Positive displacement allows for easier self-
priming.
• Pumping pressure is as high as 12 bar
(176 psi). This allows you to install your
pump in the widest variety of tank-to-
tank and tank-to-in-line applications.
• High accuracy and repeatability. A wire-
wound potentiometer and solid state elec-
tronics are combined to achieve greater
precision and control.
