Bertolini CAX triplex pumps

Bertolini’s CAX series of triplex pumps are designed for pressures up to 750 bar (10,875 psi). Based on the company’s CX series, the pump has applications in reverse osmosis, desalination, food, petrochemical and chemical industries.

The pump head is manufactured from AISI 316 grade stainless steel. The product comes with oversized tapered roller bearings, designed to endure heavy loads on extended industrial applications. The Du-dry plungers are PTFE coated to reduce friction and provide smooth operation and long wear.

Double V packings that are self-lubricating are the basis of the sealing systems. The seal area has been enlarged to improve sealing under any conditions and is an elastomer material. The crankcase, designed to be oversized for the pump, is die-cast aluminium and is treated for high strength and durability. It is anodised for corrosion resistance.

Double diameter piston guides, made of stainless steel, mean that the radial ring never comes into contact with the moving rod, eliminating wear and allowing for good lubrication. Interlocking, self-aligning, two-part connecting rods, designed for high loads, facilitate installation and removal while reducing friction and wear due to overheating.

The pumps offer flows to 31 L/min and are designed to run at 1000 rpm. Heavy-duty induction hardened crankshafts are 40 mm in diameter. The 750 bar version measures 572 x 465 x 288 mm and will run continuously up to 60°C.
