Centrifugal pump Z8

waterwith asynchronous motorsubmersible

Overview
Multistage deep well pumps of the Z8, Z10 and Z12 series are designed for pumping clean or slightly sandy liquids (maximum sand content 100 g/m³). They are adapted to wells with diameters of 8" , 10" and 12" and are available in nominal flow rates of 55, 75, 95, 125, 150, 220, 275, 340 and 420 m³/h. Standard construction uses AISI 316 stainless steel. Duplex ZR versions are available for elevated-temperature operation (up to 60°C).

Features

• Built-in non-return valve
• Rotor with replaceable wear rings
• Replaceable coupling compliant with NEMA standard
• Capability to operate in horizontal position
• Supplied with asynchronous motors L6C, L8W or L10W
• ZR versions in Duplex stainless steel for higher temperature service

Application
