The purpose of the pneumatic diaphragm pump air control system is to ensure automatic operation that is indirectly controlled by the movement of the diaphragms. Reaching its final point, the stroke reverses automatically and the cycle of medium being drawn in by one diaphragm and being displaced by the other is repeated by the opposite side of the pump.
The metal-free, pneumatically pilot-operated PERSWING P® Air Control System ensures accurate reversal of the main piston and is characterized by low noise levels. Only two moving parts ensure that there is absolutely no dead center. It does not require maintenance, operates without any lubrication and is engineered with no more than four different parts. The complete cartridge can be replaced easily. The PERSWING P® is a precision control system and, therefore, requires clean, oil-free compressed air to ensure its optimal function.
