Process Pump Series Series Compact, high capacity diaphragm pump for transfer and recovery of a wide variety of fluids Long service life, 2 to 5 times that of conventional pumps No sliding parts in wetted areas. Self-priming makes priming unnecessary Built-in pulsation attenuator Compact single acting Process pump Process pump Automatically operated type/Air operated type Automatically operated type Built-in solenoid valve type/Air operated type (Internal switching type) (Internal switching type) (External switching type) High abrasion resistance and low particle generation VQ Incorporates a new diaphragm material. Enlarged bore size and shortened stroke extend life. (Compared to series PA2000) Process pump (External switching type) (External switching type) A solenoid valve operated pump that fits in the palm of the hand Prevents spraying of discharge and foaming in tank Variations Series PA: Double Acting Pump LVN Discharge flow rate (l /min) Automatically operated type Air operated type Automatically operated type with built-in pulsation attenuator Material Body ADC12 (Aluminum) SCS14 (Stainless steel) ADC12 (Aluminum) SCS14 (Stainless steel) Series PB: Single Acting Pump PB1011 Built-in solenoid valve Application Example Transferring liquid by suction Automatically operated type Air operated type Compatible with a Control with external switching valve makes constant cycling possible wide variety of fluids Atomizing liquid Transferring liquid by pressure Stirring liquid • Prevents sticking of liquids

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...

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.)...

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,...

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...

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...

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...
