PA series

3 piston semi-hydraulic diaphragm pumps engineered for a smoother and quieter operation. Medium pressure pumps (up to 4 bar - 58 P.S.I.) and medium flow rate, in light alloy, compact design and fitted with mounting rails. All moving parts are completely submerged in oil. Piston sleeves are made of self-lubricating cast iron; 2 piston rings for each piston are used to deliver high volumetric efficiency. All parts in contact with spray material are anodized and the check valves are in stainless steel. For quick and flexible installation they are available in the following versions: VF-VC-VM-VS.

Pre-set diaphragm washer and diaphragm bolt made up of stainless steel AISI 316 (exclusive design): high protection against corrosion.

New sealing system between crankcase/head and check valves resulting in amazing reliability and featuring long life operation.

Oversized suction and pressure circuits create a smooth ?ow of the liquid: no loss of pressure.

Diaphragms to handle chemicals: specifically designed to never lose form.

Special check valve design: spheric section-shaped, made up of AISI 316 stainless steel, delivering high volumetric ef?ciencies.

Die-cast crankcase incorporating a new cooling system.

Oversized oil sight glass to provide constant lubrication and easy reading of the oil level.

Exclusive design of the internal shaping of the head to ensure the greatest suction capability.

Parts in contact with the spray liquid are anodized aluminium or stainless steel to provide corrosion resistance.
