All Hanna Instruments pumps are warranted for one year
against defects in workmanship and materials when used for their
intended purpose and maintained according to instructions.
This warranty is limited to repair or replacement free of charge.
Damages due to accident, misuse, tampering or lack of prescribed
maintenance are not covered. If service is required, contact the
dealer from whom you purchased the instrument. If under warranty,
report the model number, date of purchase, serial number and the
nature of the failure. If the repair is not covered by the warranty,
you will be notified of the charges incurred. If the instrument is to
be returned to Hanna Instruments, first obtain a Returned Goods
Authorization Number from the Customer Service department and
then send it with shipment costs prepaid. When shipping any
instrument, make sure it is properly packaged for complete
protection.

PRELIMINARY EXAMINATION
Remove the pump from the packing material and examine it
carefully to make sure that no damage has occurred during
shipping. If there is any noticeable damage, notify your Dealer.
Each pump is supplied complete with:
• 7 m (23') LDPE suction and discharge tubing
• Instruction manual
Note: Save all packing material until you are sure that the pump
functions correctly. Any defective item must be returned in
the original packaging together with the supplied accessories.
READ ATTENTIVELY THE INSTRUCTIONS
BEFORE INSTALLING OR
OPERATING YOUR PUMP
The BL electronic dosing pumps are easy to use. We recommend,
however, that you read the entire manual before using the pump.
Familiarity with the features and controls of the unit will give you
a better idea of the dosing potential and help reduce operator
errors. Please operate the pump only as directed in the instruction
manual. Follow all general safety guidelines during operation.
Remember: electrical devices are potentially hazardous. Check that
the voltage of the installation matches the voltage indicated on
the specification label on the back of the pump. Always be sure
the pump is grounded.
Note:It is the responsibility of the user to install and ground the
pump properly; it is highly recommended to install an
external switch.

Always store chemicals in safe, out of reach places. Follow the
directions for use with each chemical. Do not assume chemicals
are the same because they look alike. Hanna Instruments cannot
be held responsible for the misuse of chemicals or the pump.
Always wear protective clothing (gloves and safety glasses) when
working near chemical dosing pumps. When pumping chemicals,
make sure all tubes are securely attached to the fittings. It is rec-
ommended that tubing is shielded to prevent possible injury in
case of rupture or accidental damage.
Avoid using a pipe wrench or pliers on plastic parts and connec-
tors. These are best tightened with an open end or crescent wrench.
Avoid overtightening these parts as this could cause damage to
the seats and threads.
If a hose is used, it should be securely fastened to columns, walls,
braces, etc. This will ensure that the hose connection will remain
tight and leak free. Shield the hose from direct sunlight. Sunlight
can cause an autocatalytic reaction with some chemicals and
weaken the hose walls.
The arrow on the pump head indicates the direction of chemical
flow and should always point upwards (vertically). Never position
the pump horizontally with suction and discharge valves horizontal.
Locate the pump in an area out of the reach of children and pets.
All pumps undergo stringent tests to ensure that they comply with
their stated specifications and are calibrated at the maximum rated
pressure.

BlackStone pumps are equipped with a single control for pump
output.
Flow range is continuously adjustable from 0 to 100% of the
maximum capacity through a graded dial on the front of the pumps.
Seven models are available, each with a different dosing capacity:
HIGH QUALITY MATERIALS
To provide the maximum protection for parts that are in contact
with aggressive chemicals, diaphragms, hose connectors and
pump heads are produced using materials as PVDF and PTFE.
The ball valves are constructed in glass. The body is made of fiber-
reinforced polypropylene for strength and durability.

GENERAL DESCRIPTION
6
RELIABILITY THROUGH SIMPLICITY
All BlackStone pumps use the positive displacement solenoid
method of pumping. This method has fewer moving parts than a
standard motor-driven pump, and does not have the mechanical
failures associated with conventional 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 electronics are combined to achieve greater
precision and control.
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.

The following charts show the relationship between their flow rate
and pressure.
An increase of pressure in the system decreases the flow rate.
