VI series

Advantages

• water saving: at suction pressures < 600 mbar, the water can be completely retained in the pump
• low noise due to optimized hydraulics and separation
• low calcification risk and easy temperature control possible
• easy disassembly due to inverted design and O-ring sealing

Possible applications

• extruder degasification
• sterilization of surgical instruments, textiles and beds (steam and gas sterilization)
