Power Requirements
BlackStone pumps are designed to operate
to specifications within the following voltage
ranges:
100 - 130 Volts for -1 models
200 - 240 Volts for -2 models
To ensure maximum performance, check the
voltage at the point of supply to verify that it
is sufficient. It is recommended that you in-
stall a 1 Amp circuit breaker between the
pump and the power supply. This will give
additional protection to the internal circuit
and provide a convenient way to disconnect
the power supply prior to servicing the pump,
if needed.
Injection Point
• Choose an injection point that allows you
to mount the injection valve assembly ver-
tically.
• The spring in the injection valve assembly
(HI 721004) adds approximately 1.5 bar of
back pressure. If pumping into a high back
pressure, the spring should be removed.
Other Considerations
• If you are mounting the system to a wall,
column, etc., be sure it is strong enough
to support the weight of the entire system.
• The ambient temperature of the pump,
when in operation, should be between 0
and 50°C (32 to 122°F) and should be
protected from direct exposure to outdoor
elements (direct sunlight, rain, extreme tem-
peratures, high humidity, etc.).
• Generally speaking, the shorter the suction
distance, the more efficient the pump oper-
ates.
INSTALLATION
Materials Needed
• LDPE hose (7 meter / 22 feet) (included)
or other type of tubing (PTFE, for example)
more suitable for a specific application (op-
tional)
Optional Accessories
• 4 each, ceramic weights (HI 721008)
• 1 each, foot valve assembly (HI 721005)
• 1 each, injection valve assembly (HI 721004)
Location
A suitable location should:
• be near to a power source
• be conveniently close to the injection point
• allow easy access to the flow rate control
and pipe or hose connections
• be no more than 1.5 meters (5 feet) above
the operating position of the suction valve
assembly.
Dimensions for Installation
BlackStone pumps are designed for perma-
nent installation.
The pump can be mounted directly on a wall
or tank.
