Centrifugal pump ZA series

for cooling waterfor lubricantselectric

Immersed spindle pumps ZA series are electric pumps designed for circulation of coolants and lubricating mixtures in machine tools, glass and plastic processing machines and for applications requiring pumping of relatively large quantities of liquid with modest power and head. They are particularly suitable for partially synthetic and synthetic coolants containing additives with strong solvent properties and are capable of conveying fluids containing small impurities.

Applications

• Circulation of coolants and lubricants in machine tools
• Glass and plastic processing equipment
• Industrial systems requiring transfer of liquids with small solid contaminants
• Low-head circulation circuits where moderate flow is needed

Construction and materials

• Casing, impeller and pump body in stainless steel AISI 4.5 alloy
• Motor shaft in stainless steel Inox AISI 420
• Screws in stainless steel Inox A316
• External coating by cataphoresis
