The TopWing-series is available in 8 different sizes. Shaft seal options include single mechanical, quenched, double flushed, O-ring. Feet for vertical or horizontal mounting. Safety relief valves are available built-on or separately. Pre-heating/cooling devices in front cover and/or at the seals. Connections from 25 mm to 100 mm.

Features & Benefits

Superior hygiene - Self-draining rotorcase and mechanical seal assembled in the liquid. Low carbon stainless steel with smooth surfaces. Easy to clean – CIP,SIP or by hand, with a minimum of entrapped liquid             

Validated and certified - Pump can easily be validated in to Ultra-hygienic applications. Package of certificates available as option, as example:

  • Flow and pressure tests
  • Cleanability certificates as EHEDG and 3-A
  • Material certificates as 3.1, FDA, USP VI and AFO
  • Certificates of surface roughness, welding, electro polishing
  • ATEX certificates (Hazardous zone)
  • Quality (ISO 9001) and environmental (ISO 14000) certificates

Gentle product handling - Rotors with smooth performance and minimized backslip. Able to handle particles 

Easy maintenance - Front-loaded product seals and robust bearing assembly without shimming

Integrated shaft and gear design - The complete pump is made in stainless steal. The shaft bearings are integrated into the rotorcase. Large shaft diameters and strong bearing design results in small shaft deflections and allows having small clearances inside hydraulic part. The use of duplex steel for the rotors increases wear resistance and improve behaviour on higher temperatures.   

Different clearance classes – Depending on temperature, pressure and viscosity

Multirotors or BiWing rotors – for optimal performance
