Selection procedures: 1. First mark the intersection point for a discharge rate of 6 L/min and a discharge pressure of.25 MPa. 2. Find the pilot air pressure for the marked point. In this case, the point is between the discharge curves (solid lines) for SUP =.3 MPa and SUP =.4 MPa, and based on the proportional relationship to these lines, the pilot air pressure for this point is approximately.38 MPa. 3. ext find the air consumption rate. Since the marked point is below the curve for 5 L/min (AR), the maximum rate will be about 5 L/min (AR). 1. These flow characteristics are for fresh water (viscosity 1 mpa s, specific gravity 1.). 2. The discharge rate differs greatly depending on properties (viscosity, specific gravity) of the fluid being transferred and operating conditions (lifting range, transfer distance), etc. 3. Use.75 kw per 1 L/min of air consumption as a guide for the relationship of the air consumption to the compressor. Viscosity Characteristics (Flow rate correction for viscous fluids) Ratio of discharge rate against fresh water (%) 1 5 1 1 1 1 Viscosity (mpa s) Selection from Viscosity Characteristic Graph Required specifications example: Find the pilot air pressure and pilot air consumption for a discharge rate of 2.7 L/min, and a viscosity of 1 mpa s. Selection procedures: 1. First find the ratio of the discharge rate for fresh water when viscosity is 1 mpa s from the graph below. It is determined to be 45%. 2. ext, in the required specification example, the viscosity is 1 mpa s and the discharge rate is 2.7 L/min. Since this is equivalent to 45% of the discharge rate for fresh water, 2.7 L/min.45 = 6 L/min, indicating that a discharge rate of 6 L/min is required for fresh water. 3. Finally, find the pilot air pressure and pilot air consumption based on selection from the flow characteristic graphs. Viscosities up to 1 mpa s can be used.

In this case, the point is between the discharge curves (solid lines) for SUP =.2 MPa and SUP =.3 MPa, and based on the proportional relationship to these lines, the pilot air pressure for this point is approximately.25 MPa. 1. These flow characteristics are for fresh water (viscosity 1 mpa s, specific gravity 1.). 2. The discharge rate differs greatly depending on properties (viscosity, specific gravity) of the fluid being transferred and operating conditions (density, lifting range, transfer distance). Calculating Air Consumption (313) Find the air consumption for operation with a 4 Hz switching cycle and pilot air pressure of.3 MPa from the air consumption graph. Selection procedures: 1. Look up from the 4 Hz switching cycle to find the intersection with SUP =.3 MPa. 2. From the point just found, draw a line to the Y-axis to find the air consumption. The result is approximately 5 L/min (AR). Selection from Viscosity Characteristic Graph Required specification example: Find the pilot air pressure and pilot air consumption for a discharge rate of 2.7 L/min, and a viscosity of 1 mpa s. Selection procedures: 1. First find the ratio of the discharge rate for fresh water when viscosity is 1 mpa s from the graph below. It is determined to be 45%. 2. ext, in the required specification example, the viscosity is 1m Pa s and the discharge rate is 2.7 L/min. Since this is equivalent to 45% of the discharge rate for fresh water, 2.7 L/min.45 = 6 L/min, indicating that a discharge rate of 6 L/min is required for fresh water. 3.

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 to the outside. 4. When air enters drive chamber A, diaphragm B moves to the left pushing pilot valve B. 5. When pilot valve B is pushed, the air which was acting upon the switching valve is exhausted, and drive chamber B once again switches to a supply state. A continuous reciprocal motion is generated by this repetition. Drive unit 1. When air enters drive chamber B, the fluid in pump chamber B is forced out, and at the same time fluid is sucked into pump chamber A. 2. When the diaphragm moves in the opposite direction, the fluid in pump chamber A is forced out, and fluid is sucked into pump chamber B. 3.

Process Pump Series Piping and Operation: Automatically Operated Type Piping diagram Reset button Pilot air supply port AIR SUP Silencer Discharge port Pilot air exhaust port AIR EXH Suction port Mounting posture of the pump is set with the mounting bracket facing downward. Air to be supplied to the air supply port <AIR SUP> should be cleaned and filtered through AF filter, etc. Air with foreign matter or drainage etc. will have negative effects on the built-in directional control valve and will lead to malfunction. When air needs additional purification, use a filter (Series AF), and a mist separator (Series AM) together. Maintain the proper tightening torque for fittings and mounting bolts, etc. Looseness can cause problems such as fluid and air leaks, while over tightening can cause damage to threads and parts, etc. Operation <Starting and Stopping> Refer to circuit example (1) 1. Connect air piping to the air supply port <AIR SUP> and connect piping for the fluid to be transfered to the suction port <> and the discharge port <>. 2. Using a regulator, set the pilot air pressure within the range of.2 to.7 MPa. Then, the pump operates when power is applied to the 3 port solenoid valve of the air supply port <AIR SUP>, the sound of exhaust begins from the air exhaust port <AIR EXH> and fluid flows from the suction port <> to the discharge port <>. At this time, the throttle on the discharge side is in an open state. The pump performs suction with its own power even without priming. (Dry state suction lifting range: max. 1 m) To restrict exhaust noise, attach a silencer (A2-2: option) to the air exhaust port <AIR EXH>. 3. To stop the pump, exhaust the air pressure being supplied to the pump by the 3 port solenoid valve of the air supply port <AIR SUP>. The pump will also stop if the throttle on the discharge side is closed. <Discharge Flow Rate Adjustment> 1. Adjustment of the flow rate from the discharge port <> is performed with the throttle connected on the discharge side or the throttle connected on the air exhaust side. For adjustment from the air side, use of the silencer with throttle AS2 (port size 1/4) connected to the air exhaust port <AIR EXH> is effective. Refer to circuit example (1). (Adjust the throttle on the air side so that the exhaust air is fully exhausted.) 2. When operating with a discharge flow rate below the specification range, provide a by-pass circuit from the discharge side to the suction side to ensure the minimum flow rate inside the process pump. With a discharge flow rate below the minimum flow rate, the process pump may stop due to unstable operation. Refer to circuit example (2). (Minimum flow rates: 3 1 L/min, 5 5 L/min) <Reset Button> When the pump stops during operation, press the reset button. This makes it possible to restore operation in case the switching valve becomes clogged due to foreign matter in the supply air.

Connect air piping ote 1) to the pilot air supply port <P1>, <P2> and connect piping for the fluid to be transfered to the suction port <> and the discharge port <>. 2. Using a regulator, set the pilot air pressure within the range of.1 to.5 MPa. Then, the pump operates when power is applied to the solenoid valve ote 2) of the pilot air supply port and fluid flows from the suction port <> to the discharge port <>. At this time, the throttle on the discharge side is in an open state. The pump performs suction with its own power even without priming. (Dry state suction lifting range: 3 1 m, 5 up to.5 m ote 3) ) To restrict exhaust noise, attach a silencer to the solenoid valve air exhaust port. 3. To stop the pump, exhaust the air pressure being supplied to the pump with the solenoid valve of the air supply port. ote 1) When used for highly permeable fluids, the solenoid valve may malfunction due to the gas contained in the exhaust. Implement measures to keep the exhaust from going to the solenoid valve side. ote 2) For the solenoid valve, use an exhaust center 5 port valve, or a combination of residual exhaust 3 port valve and a pump drive 4 port valve. If air in the drive chamber is not released when the pump is stopped, the diaphragm will be subjected to pressure and its life will be shortened. ote 3) When the pump is dry, operate the solenoid valve at a switching cycle of 1 to 7 Hz. If operated outside of this range, the suction lifting height may not reach the prescribed value. <Discharge Flow Rate Adjustment> 1. The flow rate from the discharge port <> can be adjusted easily by changing the switching cycle of the solenoid valve on the air supply port.

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 to the outside. 4. When air enters drive chamber A, diaphragm B moves to the left pushing pilot valve B. 5. When pilot valve B is pushed, the air which was acting upon the switching valve is exhausted, and drive chamber B once again switches to a supply state. A continuous reciprocal motion is generated by this repetition. Drive unit 1. When air enters drive chamber B, the fluid in pump chamber B is forced out, and at the same time fluid is sucked into pump chamber A. 2. When the diaphragm moves in the opposite direction, the fluid in pump chamber A is forced out, and fluid is sucked into pump chamber B. 3. The pressure of the fluid that is forced out of the pump chamber is adjusted in the pulsation attenuation chamber and is then exhausted. 4. Continuous suction/discharge is performed by the reciprocal motion of the diaphragm. Pulsation attenuation chamber 1. Pulsation is attenuated by the elastic force of the diaphragm and air in the pulsation attenuation chamber. 2. When the pressure in the pulsation attenuation chamber rises, the change lever presses the pulsation attenuator intake valve, and air enters the pulsation attenuator air chamber. 3. Conversely, when pressure drops, the change lever presses the pulsation attenuator exhaust valve, exhausting the air from the air chamber and keeping the diaphragm in a constant position. ote that some time is required for the pulsation attenuator to operate normally. Pulsation Attenuating Capacity P X F MPa.7 MPa.7.5.5 Without pulsation attenuator With built-in pulsation attenuator The process pump generates pulsation because it discharges a liquid using two diaphragms. The pulsation attenuator absorbs pressure when discharge pressure increases, and compensates the pressure when discharge pressure decreases. By this means pulsation is controlled. 877

Series X1 Piping: Automatically Operated Type, Built-in Pulsation Attenuator Piping diagram Reset button Reset button Pilot air supply port AIR SUP Discharge port Silencer (al) Pilot air exhaust port AIR EXH Suction port Mounting posture of the pump is set with the bottom surface at the bottom. Air to be supplied to the AIR SUP port should be cleaned and filtered through AF filter, etc. Air with foreign matter or drainage etc. will have negative effects on the built-in switching valve and will lead to malfunction. When air needs additional purification, use a filter (Series AF), and a mist separator (Series AM) together. Maintain the proper tightening torque for fittings and mounting bolts, etc. Looseness can cause problems such as fluid and air leaks, while over tightening can cause damage to threads and parts, etc. Operation <Starting and Stopping> Refer to circuit example (1) 1. Connect air piping to the air supply port <AIR SUR> and connect piping for the fluid to be transferred to the suction port <> and the discharge port <>. 2. Using a regulator, set the pilot air pressure within the range of.2 to.7 MPa. Then, the pump operates when power is applied to the 3 port solenoid valve of the air supply port <AIR SUP>, the sound of exhaust begins from the air exhaust port <AIR EXH> and fluid flows from the suction port <> to the discharge port <>. At this time, the throttle on the discharge side is in an open state. The pump performs suction with its own power even without priming. (Dry state suction lifting range: max. 2 m) To restrict exhaust noise, attach a silencer (A2-2: option) to the air exhaust port <AIR EXH>. 3. To stop the pump, exhaust the air pressure being supplied to the pump by the 3 port solenoid valve of the air supply port <AIR SUP>. The pump will also stop if the throttle on the discharge side is closed. <Discharge Flow Rate Adjustment> 1. Adjustment of the flow rate from the discharge port <> is performed with the throttle connected on the discharge side or the throttle connected on the air exhaust side. For adjustment from the air side, use of the silencer with throttle AS2 (port size 1/4) connected to the air exhaust port <AIR EXH> is effective. Refer to circuit example (1). (Adjust the throttle on the air side so that the exhaust air is fully exhausted.) 2. When operating with a discharge flow rate below the specification range, provide a by-pass circuit from the discharge side to the suction side to ensure the minimum flow rate inside the process pump. With a discharge flow rate below the minimum flow rate, the process pump may stop due to unstable operation. Refer to circuit example (2). (Minimum flow rates: X1.5 L/min) <Reset Button> 1. When the pump stops during operation, press the reset button. This makes it possible to restore operation in case the switching valve becomes clogged due to foreign matter in the supply air. Maintenance is necessary if the reset button needs to be pressed frequently.
