Be sure to read before handling. Refer to pages 17-6-3 to 17-6-10 for Safety Instructions and Solenoid Valve Precautions. Caution on Design Warning 1. Confirm the fluid to be used. Be sure to confirm the specifications, as the fluids to be used differ depending on the product. When different fluids are used, characteristics change and this can cause faulty operation. 2. Fluid temperature Use each model within its respective fluid temperature range. 3. Fluid quality If fluid is used which contains foreign matter, troubles such as malfunction and seal failure may occur due to wearing of valve seats...

Process Pump Precautions 2 Be sure to read before handling. Refer to pages 17-6-3 to 17-6-10 for Safety Instructions and Solenoid Valve Precautions. Selection 1. Confirm the specifications. Give careful consideration to operating conditions such as the application, fluid and environment, and use within the operating ranges specified in this catalog. 2. Type of fluid Operate only after confirming the materials and applicable fluids for each model to determine which fluids can be used. 3. Equipment selection When selecting equipment, make a selection from the latest catalog, staying within specified...

Be sure to read before handling. Refer to pages 17-6-3 to 17-6-10 for Safety Instructions and Solenoid Valve Precautions. Operating Environment Warning 1. Do not use in the following environments, as this can cause failure. 1) Locations with an atmosphere of corrosive gases, organic solvents or chemical solutions, and where there may be contact with the same. 2) Locations where there is contact with sea spray, water or steam. 3) Locations where there is contact with direct sunlight. (Sunlight should be blocked to prevent deterioration of resin from ultra violet rays and over heating, etc.) 4)...

Process Pump Precautions 4 Be sure to read before handling. Refer to pages 17-6-3 to 17-6-10 for Safety Instructions and Solenoid Valve Precautions. Maintenance Caution 6. Concerning the life span of diaphragm and the maintenance of consumable items. 1) Regular maintenance is required for Diaphragm, Check valve and Switching valve, etc. • If the diaphragm is not functioning, the operating fluid may flow to the pilot air side and at the same time the operating air may flow out to the liquid circuit. This makes it impossible to restart the operation. • Consider the pump operation (breathing, decline...

Be sure to read before handling. Refer to pages 17-6-3 to 17-6-10 for Safety Instructions and Solenoid Valve Precautions. Fluid Compatibility Caution 1. Select models by choosing liquid contact materials suitable for the liquids to be transferred. • In liquid contact areas, aluminum is suitable for use with oils, and stainless steel is suitable for solvents and industrial water. • For the diaphragm material, nitrile rubber is suitable with inert liquids, and fluororesin is suitable with non-permeating liquids. • Use fluids which will not corrode the wetted parts materials. 2. Transfer examples...

Process Pump Automatically Operated Type Series Performance Curve: Automatically Operated Type Discharge rate (i/min) Selection from Flow Characteristic Graph (PA3000) Required specifications example: Find the pilot air pressure and pilot air consumption for a discharge rate of 6 £/m'm and a total lifting range of 25 m. <The transfer fluid is fresh water (viscosity 1 mPa-s, specific gravity 1.0). * If the discharge pressure is required instead of the total lifting height, a total lift of 10 m corresponds to discharge pressure of 0.1 MPa. Selection procedures: 1. First mark the intersection point...

Working Principle: Automatically Operated Type Drive unit Control unit Switching valve Discharge port (FLUID OUT) Pump chamber A Check valve Pump chamber B Shaft Suction port (FLUID IN) Drive chamber B Diaphragm B Control unit 1. When air is supplied, it passes through the switching valve and enters drive chamber B. 2. Diaphragm B moves to the right, and at the same time diaphragm A also moves to the right pushing pilot valve A. 3. When pilot valve A is pushed, air acts upon the switching valve, drive chamber A switches to a supply state, and the air which was in drive chamber B is exhausted...
