Your advantages

• 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 pressure 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

The portable submersible pump for reliable and long-term drainage of excavations.

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.

Description/construction

Submersible drainage pump as submersible monobloc unit for portable dry and wet well installation.

Hydraulics

The outlet on the pressure side is designed as vertical threaded connection with Storz coupling. If necessary, the outlet on the pressure side can be aligned horizontally. Semi-open, multi-channel impellers are used in the process. The inlet has been equipped with a suction strainer. Consequently, coarse elements in the fluid are filtered upstream of the suction port.

Motor

AC and three-phase current version IE3 motors are used in the process. Motors feature thermal motor monitoring. The motor is cooled by the sheath flow cooling. Continuous duty is possible when immersed/non-immersed, also in slurping operation.

A sealing chamber protects the motor from fluid ingress. The filling fluid used is potentially biodegradable and environmentally safe.

Detachable connection cables, the cable is 23 m long and features bare cable ends. The A version is also equipped with a float switch.

Seal

The sealing on the fluid side and on the motor side is performed by two bidirectional mechanical seals.
