1. Introduction

This pump is a positive-displacement pump that transfers fluids by means of diaphragms movement operated by

compressed air. The casing in contact with the fluid is made of PE (polyethylene), PE conductive, PTFE

(polytetrafluoroethylene), PTFE conductive.

2. For safe operation

This document contains information indispensable for maintaining safe and efficient operation of this product.

Read this document carefully before using the pump particularly the "warnings and cautions". Get familiar with all

operating procedures. This document must be kept handy for future reference.

3. Warnings and cautions

The meanings of warning and caution symbols are given below. Be sure to remember their meanings.

WARNING

ignoring the warning and operating the product in an improper manner can result

in danger of serious bodily injury or death.

CAUTION

:ignoring the warning and operating the product in an improper manner can result

in danger of personal injury or property damage.

ØThis symbol means a DON’T, and will be followed by an explanation on what you must not do.

!This symbol means a DO, and will be followed by an explanation on what you must do in a specified situation.

4. Operating caution

Before using this product

WARNING

!Todrive thepumpyou mustuseone ofthe followingcompressedgases(calledin thisdocument "compressedair"):

-Compressed air supplied from air compressor

- Nitrogen(N

)gas

Useofcompressed airother thantheabove maycauseairpollution,damagetothepump,orevenanexplosion.

!Themaximumpermissiblepressureforthecompressedair,andthefluidpumpedbyone ofthispumps, 8bars.Should

the aboveapplicablemaximumpermissiblepressurebeexceeded,thefollowingresultsmayfollow:

damage to the casing, or even a severe, possibly fatal accident.

In some pomp executions, specified by manufacturer, the max. pressure can reach 14 bars.

!In case a diaphragm gets damaged,fluid willgush out together with air through the exhaust port. Provide

protective measures in consideration of possible leakage of fluid.

WARNING

CAUTION

When installing this product, be sure to connect a ground wire from the specified position of this product.

Otherwise friction between parts and abrasion caused by the flow of some fluids inside the casing may

generate static electricity. Depending on the type of fluid being pumped and the installation environment

(such as gases in the air and type of surrounding fixtures), static electricity could cause fire or electric shock.

!Some fluid may remain inside the pump and inside the connected piping after shutting down the pump, or if

the pump is left unused for a prolonged period.

Therefore, be sure to purge the system of fluid and clean the pump before prolonged disuse.

The fluid remaining in the connected piping as well as the pump itself may expand because of freezing or

heat which may cause damage to the pump or/and piping and lead to leakage of the fluid.

Use only genuine Dellmeco parts when replacing component parts of this product.

!Torque of all tightening parts must be checked before running the pump. Designated torques are mentioned

in maintenance manual.

!In case of pumping a hazardous fluid (hot, flammable, strong acid, etc.) with this pump, protective measures

(install a pit, a protection box, sensors, etc.) must be provided in consideration of possible leakage of fluid.

Warning signs must be displayed at necessary places. Leakage of fluid may cause fire or accident.

!Before using this pump, get fully familiar with the precautions regarding the fluid to be pumped, and verify

the corrosion resistance of the parts that will come into contact with the fluid. NEVER use the pump with any

fluid against which it does not have sufficient corrosion resistance or with a fluid that poses a risk of

explosion. If you are unable to verify the corrosion resistance, contact your dealer. Using this product with

any fluid against which the parts in contact with the fluid do not have sufficient corrosion resistance may

result in damaging the product or leakage of fluid.

!The running pump may generate loud operating noise. Its level will vary depending upon the conditions of

use (fluid pumped, supply air pressure and discharge pressure)

!To drive this product, supply air with minimum moisture content and without any oil must be used.

!If a diaphragm of this pump is damaged, supply air may mix with the fluid or the fluid may flow into the

central housing. DO NOT OPERATE THE PUMP if air supply is inadequate or contaminated.

While operating this product, do NOT put your hand on the inlet port.
