SAFETY INSTRUCTIONS
Special care should be taken when operating an electrical device. To avoid
serious or fatal personal injury or major property damage, read and follow all
safety instructions in manual and on pump.
WARNINGS
• DO NOT operate pump in the vicinity of explosive or flammable materials,
liquids or gases.
• DO NOT operate pump if it has being inundated by water.
• DO NOT operate pump if it has a damaged cord or plug, if it is not working
properly, or if it has been damaged or dropped.
• To avoid Electric Shock resulting from water back-siphoning, pump must be
installed above the water level.
CAUTIONS
• Operate the pump only in fully assembled state.
• This product is designed to pump air only. Do not attempt to pump any
other gases or fluids. Any airborne contaminants must be filtered out.
• Do not lubricate this oil-less air pump. No parts on this pump have oil or
require lubrication. Avoid close proximity to products that may release oil or
gasoline vapors.
• Connect the pump only to an outlet with GFCI (see Electrical Safety).
• Reduce the risk of bursting by only use air handling devices rated for
pressure no less than 8 psi or 55 kPa.
• Keep power cable away from heated surfaces and pedestrian traffic.
INSTALLATION and OPERATION
Place the pump upright securely on a dry and stable surface that is easily
accessible for inspection. Avoid location or elevation that will be inundated by
water. For aeration applications, the pump must be installed above the water
surface level.
PROPER VENTILATION
Allow ample clearance around the pump for free air circulation. Good
ventilation ensures proper heat dissipation which lowers internal operating
temperature and prevents thermal stress to key components.
When pump is to be placed under a protective enclosure, avoid designs that
can cause thermal insulation. Install forced ventilation system to promote air
circulation under the enclosure and improve pump reliability. Certain indoor
installation may also require forced ventilation when the forces of air pressure
and gravity are not enough to circulate air through a room or building.
- 3 -

- 4 -
For outdoor installations, shaded area that shelters from excessive weathering
is ideal. Do not allow pump to swelter under intense sun and avoid places with
excessive dust or debris.
The ambient operating temperature for this pump is between 5°C (41°F) and
40°C (104°F). Operation of pump in temperature outside of the recommended
temperature range may result in malfunction or severely shorten the pump life.
PIPE SIZING
Utilize air tubing or pipes that are equal or larger than the pump discharge port.
Matching pipe fittings should be used to reduce frictional losses. Incorrect pipe
sizing can cause unsatisfactory performance.
When selecting or constructing an air manifold, the number of outlet fittings and
their orifice size must be considered carefully to minimize frictional losses. Do
not block or restrict pump discharge for extended periods. Install a bleed valve
to vent any excess air volume and attach an air diffuser as silencer or muffler.
ELECTRICAL SAFETY
Form a drip loop with the power cord before connecting to the electrical
terminal. Drip loops can prevent water from traveling down the cord and
entering the power connection.
In the event of an electrical short circuit, grounding reduces the risk of electric
shock by providing an escape wire for the electric current. This pump is
equipped with a cord having a grounding wire with an appropriate grounding
plug. The plug must be plugged into an electrical terminal that is properly
installed and grounded in accordance with all local codes and ordinances. Do
not modify the plug provided; if it does not fit the outlet, have the proper outlet
installed by a qualified electrician.
Connect the pump only to a terminal with Ground
Fault Circuit Interrupter (GFCI) installed. This
device should serve to interrupt the flow of electric
current in the event of ground faults (electrical
current that unintentionally flows to ground). Check
proper operation of GFCI every month, and replace
faulty GFCI immediately.
EXTENSION CORD
If an extension cord is required, use only a 3-wire extension cord that has a 3-
blade grounding plug, and a 3-slot receptacle that accepts the plug on the
pump. Be sure to use one heavy enough to carry the current the pump draws.
For lengths less than 50 feet, No. 16/3 AWG extension cord shall be used. An
undersized cord can result in a drop in line voltage, loss of power and
overheating. Replace any damaged extension cord immediately.

MAINTENANCE INSTRUCTIONS
Periodic pump maintenance is required for reliable continuous operation. Any
maintenance of the pump other than those described herein this manual must
be performed by an authorized service facility.
CAUTION: Always turn off the power and unplug from electrical terminal before
any maintenance. Failure to observe this precaution can result in serious
accident.
AIR FILTER
Air filter pad under the filter cover should be cleaned every 3 to 6 months.
Wash the filter pad gently in mild, soapy water then rinse thoroughly. Allow
filter pad to dry completely before reinstalling.
DIAPHRAGM MODULES
Diaphragm module replacement is typically recommended for every 24 months
of operation. Replacement cycle may differ from application to application, it is
prudent to perform the replacement before any actual diaphragm failure.
Diaphragm Replacement Kit (DRK) can be ordered from Alita Industries or
authorized Alita representative.
Diaphragm Module Replacement
1. Set pump upside down (remove filter cover for stability if required), unscrew
and remove all upper housing screws. Then return pump to upright position
and lift away upper housing. Number of housing screws: AL-30~80 (4x),
AL-100~200 (6x), AL-250~400 (12x)
2. Detach the L-tube from discharge port of each diaphragm housing.
3. Select a diaphragm housing on core frame, remove its 4 corner screws,
then pull housing away. Proceed to remove the hex nut and washer from
center of the diaphragm then pull and slide the entire diaphragm block away
from magnetic rod and core frame.
4. Select a new diaphragm block from the DRK, align shape with core frame
and magnetic rod then slide over the rod screw. Secure assembly firmly with
washer and hex nut. Apply 1 to 2 drops of removable grade threadlocker
between the hex nut and protruded rod screw.
5. Install new diaphragm housing then secure with 4 corner screws.
6. Attach L-tube to the discharge port of the new diaphragm housing then
secure with silicone band or wire hose clamp.
7. Repeat step #3 through #6 on opposite side.
IMPORTANT: Do not mix old and new parts. For reliable operation, always
replace both diaphragm modules in the pump at the same time.
8. Inspect the position of magnetic rod from the top. Magnetic rod should be
centered between the electromagnets. No contact should exist between the
magnetic rod and the two electromagnets.

- 6 -
9. If the pump includes a protective switch on top
of the pump core, rotate and reset the switch to
ON position. (See illustration)
10. Install upper housing, and secure firmly with all
housing screws.
Magnetic Rod Replacement
Magnetic Rod between the two diaphragms may
get damaged if diaphragm failure has already
occurred. If the magnetic rod has suffer damages,
order a new magnetic rod along with the diaphragm

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 dif-
ferent 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)
BL 5 5.0 lph (1.3 gph) @ 7 bar (101.5 psi)
BL 3 2.9 lph (0.8 gph) @ 8 bar (116 psi)
BL 1.5 1.5 lph (0.4 gph) @13 bar (188.5 psi)
High quality materials
To provide the maximum protection for parts
that are in contact with aggressive chemi-
cals, diaphragms, hose connectors and pump
heads are produced using materials as PVDF
and PTFE.
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 plas-
tic 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 re-
main 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 al-
ways point upwards (vertically). Never posi-
tion 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 specifica-
tions and are calibrated at the maximum
rated pressure.

The ball valves are constructed in glass. The
body is made of fiber-reinforced polypropy-
lene 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.
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.

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.

1514
It is recommended that the system be con-
nected to a power line/leg equipped with a
circuit breaker of 1 Amp.
Permanent Connection using 3/8"PVC pipe
All piping for the
pump feed and dis-
charge should be
plumbed to the loca-
tion of the pump.
The threads on both
valve assemblies al-
low the use of stan-
dard 3/8" (European)
pipe fittings for per-
manent pipe connec-
tions.
The foot valve as-
sembly (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 dis-
charge valves to the PVC pipe.
Hose Connections
• Cut a long enough
section of the
hose to reach the
suction valve of the
pumphead from

•The pump should be placed in a conven-
tional 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 5 mm (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.
Electrical Connections
Note: All cables must be according to local
electrical codes.
For safety of the users, the pump has to
be grounded.
The pump should be connected to a single
phase power source.
