WARNING
Turn off power before work
Risk of electrical shock. Be sure to turn off power to stop the pump and
related devices before service is performed. Let other people know about
the situation by displaying a notice such as "POWER OFF (Maintenance)"
near the power switch.

immediately and inspect/solve problems.
Do not use the pump in any condition other than its intended purpose
The use of the pump in any conditions other than those clearly specied
may result in failure or injury. Use this product in specied conditions only.
Do not modify the pump
Alterations to the pump carries a high degree of risk. It is not the manufac-
turer's responsibility for any failure or injury resulting from alterations to the
pump.
Wear protective clothing
Always wear protective clothing such as an eye protection, chemical re-
sistant gloves, a mask and a face shield during disassembly, assembly or
maintenance work. The specic solution will dictate the degree of protec-
tion. Refer to MSDS precautions from the solution supplier.

full understanding of the pump. Any person not familiar with the product
should not take part in the operation or maintenance of the pump.
Use specied power only
Do not apply any power other than that specied on the nameplate. Other-
wise, failure or re may result. Ensure the pump is properly grounded.
Ventilation
Fumes or vapours can be hazardous with certain solutions. Ensure proper
ventilation at the operation site.
Do not install or store the pump:
• In a ammable atmosphere.
• In a dusty/humid environment.
• In a corrosive atmosphere.

Requirement
Flush the inside of the pump and piping with pure water or the liquid to be
delivered before the start of operation.
Static electricity
When low electric conductivity liquids such as ultra-pure water and fluor
TM
inactive liquid (e.g. Fluorinert
) are handled, the static electricity may be
generated in the pump and may cause static discharge. Take counter-
measures to remove the static electricity.
Before returning product
Be sure to drain chemicals and clean the inside of the pump before return
so that a harmful chemical does not spill out in transit.
Disposal of a used pump
Dispose of any used or damaged pump in accordance with relevant regu-
lations. Consult a licensed industrial waste products disposing company.
CAUTION

Precautions for use
• Electrical work should be performed by a qualied electrician. Otherwise,
personal injury or property damage could result.
• Do not install the pump:
–In a ammable atmosphere.
–In a dusty/humid place.
– In a corrosive atmosphere.
• Allow sufficient space around the pump for easy access and maintenance.
• Use care handling the pump. Do not drop. An impact may affect pump
performance. Do not use a pump that has been damaged to avoid the risk
of electrical damage or shock.
Caution
Caution
Caution
• The pump is not waterproof. Do not operate the pump while wet with solu-
tion or water. Failure or injury may result. Immediately dry off the pump if it
gets wet.
• Do not close discharge line during operation. Solution may leak or piping
may break.
• Solution in the discharge line may be under pressure. Release the pres-
sure from the discharge line before disconnecting plumbing or disassembly
of the pump to avoid solution spray.
• Wear protective clothing when handling or working with pumps. Consult
solution MSDS for appropriate precautions. Do not come into contact with
residual solution.

Overview
Pump working principle, part names and identication codes are de scribed in this section.
Introduction
Pump structure & Operating principle
The rotational motion of the stepping motor is changed to linear motion by the direct drive unit. Liquid is loaded
into the pump head and then delivered to a discharge line as the bellows reciprocates.
Principle of operation
● The bellows expands and contracts as the ball screw reciprocates.
● The reciprocating motion of the bellows compresses or expands the shape of the tubephragm via hydraulic
uid.
● Volumetric change is created in the tubephragm.
● Liquid is taken in as the tubephragm expands and is pushed out as it contracts in sync with the action of the
check valves (pump head valves).
