Impeller pump Padus PRO series

waterelectricsubmersible

Product overview
The Wilo-Padus PRO is the ideal submersible drainage pump for the drainage of excavations. Thanks to its robust construction, the wear-resistant material combinations and passive cooling in slurping operation, the submersible drainage pump with IE3 motor and integrated protection function is especially suitable for continuous duty in abrasive fluids. It can be used flexibly thanks to its low weight and flexible pressure connection. Quick access to the most important components also simplifies commissioning and maintenance. The Wilo-Padus PRO also fulfils all digitalisation requirements for the optimal planning of future maintenance work.

Key benefits / Highlights

• High reliability in abrasive fluids thanks to rubber-coated hydraulics and an impeller made of Duplex chrome steel
• Easy installation thanks to low weight and flexible discharge connection (vertical/horizontal)
• Active cooling for reliable continuous operation
• Continuous duty in slurping operation thanks to passive cooling
• Easy maintenance thanks to quick access to wearing parts
• Equipped with energy-efficient IE3 motor technology as standard
• Highest operational reliability thanks to integrated protection function

Product features
