Dear Customer,
Thank you for choosing a Hanna product.
Please read this instruction manual carefully
before using the pump.
If you need additional technical information,
do not hesitate to e-mail us at
tech@hannainst.com.
These instruments are in compliance with the
directives.
WARRANTY
All Hanna Instruments pumps are warranted for
one year against defects in workmanship and materi-
als 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 pro-
CE Declaration of Conformity .................... 31
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 recommended 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 connectors. 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.
GENERAL DESCRIPTION
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:
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.
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 selfpriming.
• 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 wirewound 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.
FLOW RATE CHART
The following charts show the relationship
between their flow rate and pressure.
An increase of pressure in the system decreases the flow rate.
