The use of the pump in any purpose other than those clearly speci-
ed may result in failure or injury. Use this product in a specied
condition.
Do not modify the pump

responsible for any failure or injury results from remodelling.
Wear protective clothing
Always wear protective clothing such as an eye protection, chemi-
cal resistant gloves, a mask and a work cap during dismantlement,
assembly or maintenance work.
Do not damage the power cable

Requirement
A qualied operator only
The pump must be handled or operated by a qualied person with a
full understanding of the pump. Any person who is not familiar with
this product should not take part in operation or management.
Use a specied power only
Do not apply any power other than the one specied on the nameplate.
Otherwise, failure or re may result.
Do not run pump dry
Do not run pump dry for more than 30 minutes (even when the
pump runs for degassing). Otherwise, the pump head unit xing
screws may loosen, or the pump head unit and valve case may
deform by friction heat, and consequently leakage results. Optimise
your system in order for the pump not to run dry.
Do not wet electric parts or wiring
Risk of re or electrical shock. Install the pump free from liquid spill.
Ventilation
Poisoning may result when handling a toxic or odorous liquid. Keep
good ventilation in your operating site.
Do not install or store the pump in the following places where...
• Under a ammable atmosphere or in a dusty/humid place.
• Ambient temperature is beyond 0-40 degrees Celsius.
• Under direct sunlight or wind & rain.
Countermeasure against efux
Take a protective measurement against an accidental chemical
overow results from pump or piping breakage.

Do not use the pump in a water place
The pump is not totally waterproof. The use of the pump in water or
high humidity could lead to electrical shock or short circuit.
Wear part replacement
Follow instructions in this manual for wear part replacement. Do not
dismantle the pump beyond the extent of the instructions.
Do no use a damaged pump
Using a damaged pump could lead to an electric leak or shock.
Disposal of the used pump
Dispose of any used or damaged pump in accordance with relevant
regulations. Consult a licensed industrial waste products disposing
company.
Keep the pump head unit securely xed
Liquid may leak if pump head unit xing screws are loose. Tighten
the screws diagonally and evenly before initial operation. Also, peri-
odically tighten the screws for the prevention of leakage.
Tightening torque: 0.7 N•m

Requirement
• Electrical work should be performed by a qualied opera-
tor. Otherwise, personal or property damage accident may
result.
• Do not install the pump in the following places where...
–Under a ammable atmosphere or in a dusty/humid place.
–Under direct sunlight or wind & rain.
– Ambient temperature is beyond 0-40 degrees Celsius.
Protect the pump with a cover when installing it out of
doors.
• Select a level location where is free from vibration and
liquid can't stay. Fix the pump with M4 screws so as not to
vibrate. If the pump is installed at a tilt, the ow may reduce.
• When two or more pumps are installed, the pump opera-
tion interacts each other and vibration becomes signicant,
resulting in poor performance or failure of internal electri-
cal devices. Select an installation location where tolerates
vibration to enough degree.
• Keep a wide maintenance space around the pump.
• Install the pump as close to a supply tank.
• Install the pump in a cool and dark place when handling
liquids that readily generate gas bubbles such as sodium
hypochlorite or hydrazine solution. Flooded suction mount-
ing is strongly recommended when using the pump with a
supply tank.

impact may reduce pump performance. Do not use a pump
which has once damaged. Otherwise an electrical leak or
shock may result.
• The pump is a light water-/dust-proof structure of IP65, but
is not totally waterproof. Do not have the pump wet with the
liquid handled or rainwater.
• Never wet the pump head, control unit and drive unit. Oth-
erwise, Failure or an accident may result. Immediately wipe
off liquid if the pump has got wet.
• Do not close the discharge line during operation. Other-
wise, liquid may leak or tubing may break.
• Do not remove the control unit. Otherwise, an electrical
circuit or the drive unit may fail.
• Release the pressure from the discharge line before disman-
tling the pump or removing tubing. Otherwise, chemical liquid
gushes out.
• Be careful not to come in contact with residual liquid.
• Do not clean the pump or nameplate with a solvent such
as benzene and thinner. This may discolour the pump or
erase printing. Use a dry cloth or a wet cloth with water or
neutral detergent.

Introduction
Pump structure & Operating principle
The HRP series is a diaphragm metering pump which consists of a pump
head, drive unit and control unit. A diaphragm is directly driven by electromag-
netic force.
Principle of operation
The pulse signal controls the electromagnetic force in order to make recip-
rocating motion that is assisted by spring force. The reciprocating motion is
transferred to a diaphragm through a plunger and then volumetric change oc-
curs in the pump head. This action transfers liquid along with pump head valve
action.

Features
12/24VDC power voltage
The HRP series powered by 12VDC or 24VDC offers the best t to the built-in
application.
High resolution
Digitally-controlled spm range is 0-720spm. The minimum ow of 0.055ml per
shot offers a constant imperceptible injection.
* The operation speed of the stop control type is always xed to 720spm and is not vari-
able.
Waterproof and dustproof structure
The sealed drive unit and control unit assure the water-/dust-proof of IP65.
* This pump is not completely water resistant. Do not expose it to wind and rain.
Operational function
The HRP pump is controlled by the external signal and falls into the following
types.
Pulse control type (see page 27)
The input of the pulse signal controls the pump operation (stroke rate).
The pump makes one shot per pulse synchronously.
*The signal input is required to make operation after power activation for this type.
* The pump can not run over 720spm even if the external signal is entered to run the
pump beyond the maximum spm.
4-20mA control type (see page 27)
The input of 4-20mA proportionally controls the pump operation (stroke rate).
*The signal input is required to make operation after power activation for this type.
1-5V control type (see page 28)
The input of 1-5V proportionally controls the pump operation (stroke rate).
*The signal input is required to make operation after power activation for this type.
Stop control type (see page 28)
The input of the stop signal suspends the pump operation.
* This type of pump starts to run at 720spm upon power activation.
