PAGEBOY SERIES SFD POCKET SIZE DIAPHRAGM PUMP

Pneumatically Powered Diaphragm Pumps For Liquids

DESCRIPTION
The Pageboy series SFD15 pneumatic diaphragm pump is a unique, pocket-sized, air operated diaphragm pump that incorporates a stress-free diaphragm to give very high reliability and long life, even when pumping strong acids or powerful solvents (MEK, acetone, chloroform etc.).

GENERAL

The pump consists of a chamber that is divided into compartments by a diaphragm. One chamber is the pneumatic pressure/vacuum chamber(B). The other is the pump chamber (C).

Compressed air enters through a venturi which reduces pressure in the pressure/vacuum chamber (B) causing the diaphragm to move away from the pump chamber (C). This is the suction stroke. The diaphragm pushes the control rod until the poppet valve (A) closes the air exhaust port. As the air pressure rises in the pressure/vacuum chamber (B) the diaphragm is forced into the pump chamber. This is the delivery stroke, during which the diaphragm pulls the control rod off its seat. This allows air through the venturi causing the suction stroke to be repeated.

The diaphragm is used simply to separate the air from the liquid and thus operates without stress. The result is very high reliability, particularly when compared with other types of diaphragm pumps. The pump is self-priming, has low air consumption and is safe to use in a hazardous area. It stops automatically against a closed valve, maintaining a delivery line pressure equal to the air supply pressure. It starts automatically when the delivery line pressure falls such as when a valve is opened.

The pump is designed for vertical-upward flow and can be mounted by the extended tie-rods supplied.
