IWAKI ANTI-GAS LOCK PUMP UNIT The Auto-air vent valve eliminates the gas-lock problem with continuance bleeding liquid and gas constructions. A precise flow measuring per stroke and a feed back control enable precise chemical dosing, mean while the bleeding system is normally difficult to keep precise dosing. The system can also bleed gas out as short time as possible, even if setting discharge flow is small. Philosophy of the Non-Gas Lock system Flow Measured flow 10 mL/min Measured flow 0 mL/min Measured flow 0 mL/min 10 mL/min Set = operating pump speed 10 mL/min Gas with liquid The bleeding system takes gas and liquid out from the pump chamber. However, dosing capacity is kept setting volume due to feed back control with the flow signal. Set = operating pump speed 10 mL/min Set = operating pump speed Max. speed When large volume of gas comes into the pump chamber, pump discharge capacity will be "zero" until bleeding the gas out. The feed back control increase pump operating speed, thus gas bleeding time will be in short time. When the gas bleeding is completed, the pump discharge volume returns to the setting valve immediately by the feed back control with the flow signal.
