General description
The pump is designed and constructed to pump and compress liquids on spraying machines for the protective
treatment of agricultural crops and garden plants.
The pump incorporates radial pistons which actuate the diaphragms by means of an oil cushion. The dia-
phragms are connected to the pistons in their middles by means of plates and secured at the edges between
the cylinder liner and head.
The motion of the piston draws the diaphragm inward (intake) and then outward (delivery). The flow of liquid
is regulated by the intake and delivery valves.
Oil between the pump body and diaphragm serves not only as a lubricant but also as a pressure compensation
medium.
