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') LPDE 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.
32
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 DOSING PUMPS
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:
BL 20 18.3 lph (4.8 gph) @ 0.5 bar (7.4 psi)
BL 15 15.2 lph (4.0 gph) @ 1 bar (14.5 psi)
BL 10 10.8 lph (2.9 gph) @ 3 bar (43.5 psi)
BL 7 7.6 lph (2.0 gph) @ 3 bar (43.5 psi)

COMMON FEATURES OF BLACKSTONE
PUMPS
High quality materials
BlackStone pumps incorporate Kynar® and
Teflon® into their diaphragms, hose connectors and pump heads to provide maximum
protection for parts in contact with aggressive chemicals.
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-totank 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.
Kynar® is registered Trademark of "Pennwalt Co."
Teflon® is registered Trademark of "du Pont de Nemours & Co."
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.

VALVE / HOSE ASSEMBLY DIAGRAM
NECK
INSTALLATION
Materials Needed
•LDPE hose (7 meter/22 feet) (included)
or other type of tubings (Teflon®, for example) more suitable for a specific application (optional)
•a 3-wire power cable (for BL7913 and
BL7914 only)
Optional Accessories
•4 each, ceramic weights (HI 720032)
•1 each, foot valve assembly (HI 712005)
•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 permanent installation.
1918
The pump can be mounted directly on a
wall or tank (see pages 12-17 for the specific mounting dimensions).
Power Requirements
BlackStone pumps are designed to operate
to specifications within the following voltage
ranges:
100 - 130 Volts for 115V models
200 - 240 Volts for 220V models
To ensure maximum performance, check
the voltage at the point of supply to verify
that it is sufficient. It is recommended that
you install 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.
Inside BL7913 and BL7914, for increased
safety, the incoming voltage of either 115 or
240V is reduced to 12V by an isolated trans-
former. With a maximum voltage of 12V
and with the transparent cover installed, risk
of electrical problems is minimized. This
makes the unit safer to operate with.
Injection Point
• Choose an injection point that allows you
to mount the injection valve assembly vertically.
• 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
temperatures, high humidity, etc.).
• Generally speaking, the shorter the suction distance, the more efficient the pump
operates.
• The pump should be placed in a conventional location that will allow easy access
to the control and connections. It should
be placed so that regular visual inspections of the connections and hoses are
facilitated.
Vertical Surface Mounting
Once you have selected the best installation
site, simply screw or bolt the unit into a wall
or mounting panel above the chemical feed
tank.
The 4 mounting screw holes on the pump
will accommodate up to a 5mm (3/16") screw
or bolt (remember to use heavy screws or
bolts to secure the system).
Be sure you do not over tighten and cause
excessive stress on the mounting holes.
For BL7913 and BL7914
Make sure to leave a slight overhang in
front to allow for the connection cable.
Electrical Connections
Note: All cables must be according to local
electrical codes.
For safety of the users, the pump has to
be grounded.
For BlackStone Pumps:
The pump should be connected to a single
phase power source.

for permanent pipe connections.
The foot valve assembly (HI
721005) should always hang
vertically and not lay horizontal on the bottom of the
tank or drum.
A vertical assembly will ensure that the valve is positioned properly and prevent
loss of prime.
For the U.S. standard installations, use PVC adapters to connect the suction
and discharge valves to the
PVC pipe.
Hose Connections
•Cut a long enough
section of the hose
to reach the suc-
tion valve of the pumphead from the feed
tank. Allow some slack in the hose and be
sure it is not kinked or twisted.
•Slip a hose connector
onto the hose over the
head valve and up to
the bottom of the
threads ensuring it is
fully seated.
•Slide the connector up
to the threads and
tighten to form a seal.
•Slip the ceramic weight
(HI 721008) and a connector over the other end
of the hose.
•Attach the foot valve assembly (HI 721005) to
the hose and slide the
connector up to the
threads and tighten to
form a seal.
2524
•Repeat the same installation procedure for
the hose connections on the discharge end
with the injection assembly (HI721004).
Assembling the Hose to the Valve
The end of the valve is specially tapered to
form a leak free seal when the hose is properly installed.
Be sure to seat the hose completely so that
there is no gap. Push the hose until it covers the end of the valve completely.
Suction and Discharge Valves
The suction and discharge valves located
on the pumphead should not be interchanged
as they are different internally. The discharge
valve is fitted with a valve guide and will not
function properly if used on the suction side.
•Secure the hose so that its movement is
minimized when the pump is operating.
Excessive hose movement could cause
the connectors to loosen and result in leakage.

Uphill Installation
Suggested installation
whenever the supply
is located higher than
the discharge point;
typically a waste water application.
It is important to install the Injection
valve to prevent siphoning.
Flooded Suction Installation
Suggested Installation for consistent
output when using
a low stroke rate.
Also suggested for
highly viscous
chemicals.
A slight suction
pressure avoids
self-priming problems, especially
with high viscosity
liquids.
Suction Lift Installation
Suggested installation for
most in-line applications
with nominal output and
pressures.
The maximum self-priming height is 1.5 m (5 ft.).
It is advisable to install a
level controller in order
to stop the pump when
feed tank liquid level is
low.
Downhill Installation
Suggested installation when
pumping from
one container to
another, each at
different levels
and with only
nominal pressure.

Operating Pressure and Back Pressure
Operating pressure is a combination of back
pressure plus all of the other resistances to
flow present in your system.
BlackStone Pumps are designed to dose
their rated output at the operating (
rated
pressure.
Therefore,
rated
pressure of the pump you
install should be close to operating pressure
present in the system.
Too little back pressure can cause the pump
to overdose.
To prevent this from happening on a low
back pressure installation, a spring has been
added to the discharge/anti-siphon valve assembly (HI 721004).
When pumping into a high back pressure,
the spring should be removed.
)
3130
Actual Flow Rate
The actual flow rate depends upon the operating pressure which includes resistance at
the injection fittings, hose and piping, the
chemical viscosity and suction lift. The Flow
Rate Control adjusts the flow up to 100% of
the
rated
output. Less back pressure will
increase the output, more will decrease it.
To determine the correct setting for your
application, use the following procedure.
1. Be sure that the pump is primed and that
the output connections are completed at
the injection point.
2. Place the foot valve as-
sembly (HI 721005) in a
graduated container with
500 mL of the solution to
be dosed.
3. Switch the pump from
OFF to the 100% setting
and run until the system
has been fully reprimed.
Switch OFF and refill the
container to the 500 mL

TROUBLESHOOTING GUIDE
Electrical
The pump does not operate when turned
ON:
• Check the power supply and connections.
Voltage should be between 100 - 130 VAC
for 115 V models and between 200 240 VAC for 220 V models.
• Check wiring color scheme. See Installation section on page 19 or call for technical assistance.
•Check fuse (BL7913 and BL7914).
Liquid
The pump operates but does not prime:
• Check for a clogged or loose filter on the
suction valve assembly. Retighten if
necessary.
• Check to see if the pump is too high
above the foot valve assembly (HI 721005)
in the feed tank. This vertical distance
should not exceed 1.5 meters (5 feet).
Either lower the pump or raise the feed
tank.
• Check the pumphead, suction and
discharge valves for blockage.
• Check for any changes in the viscosity of
the chemicals being used. Increase the %
flow by adjusting the Flow Rate control to
a higher setting and run a Flow Rate test.
• Be sure that valves have been properly
installed in the pumphead.
Leakage at the connections:
• Be sure that the hose is fully seated and
hose connectors are tight.
• Be sure that valves are tight and o-rings
are in place.
Leakage around the pumphead:
• Be sure that the valves are tight and
o-rings are in place and the head screws
(hex bolts) are tight.
Pump flow rate is reduced:
• Check the pumphead, discharge and injection valve assembly for any clogging.
Clean and reassemble.
• Check for any additional back pressure
created since the last flow rate was conducted.

MAINTENANCE
Your BlackStone Pump is designed to give
you years of trouble-free service. Maintenance should be the preventative type, that
is, periodic cleaning and inspecting for any
damage or leakage.
Cleaning the Suction, Discharge and Injection Valves
Remove the valves from the pumphead,
the injection fitting and the feed.
Keep the suction and discharge valves separated as they are not interchangeable.
Disassemble each valve and clean it with a
neutral liquid. Inspect the Kynar® springs.
After cleaning the glass balls, inspect them
for any excessive wear due to abrasion from
the chemical. Replace if necessary with parts
from HI 721102, HI 721103, HI 721104 and
HI721105 (see page 40 for listing).
When reinstalling the valves into the
pumphead, tighten by hand first and then
with a wrench ¼ to ½ turn.
Cleaning the Pumphead
The pumphead should be cleaned at regular
intervals and at least once a year. Remove
the deposits that form in the cavities with a
solution that is neutral to the chemical the
pump has been dosing. Inspect the head
for any cracks or worn areas.
Replace if necessary with parts from the
pumphead spare part HI 721106 (for BL7,
BL10, BL15, BL20, BL7913 and BL7914) or
HI721107 (for BL1.5, BL3 and BL5).
SCHEDULED MAINTENANCE
After 50 hours
Tight the pumphead screws with a torque
force of 2.5 Nm (22" lbf).
After 12 months
It is recommended to replace HI 721102, HI
721103 (suction and discharge valves assemblies) as well as the o-rings. The LDPE
hose can also deteriorate over time and, for
safety reasons, should also be changed
with HI 720032.
Inspecting the hose
(if used as supplied
with the pump)
Inspect to see if the hose has worn out or
weakened due to the chemicals. Pay particular attention for any signs of abrasion or
discoloration. Also check the connectors to
ensure they are tight.
Replace if necessary with parts from HI
720032.
