Wilo-Padus UNI

Description

The Wilo-Padus UNI is the ideal entry-level model for wastewater transport in small commercial buildings. The pump can be used flexibly as a portable device or in a pump chamber. Hydraulics made from corrosion-free composite material provide high levels of reliability for universal use in the pumping of a diverse range of fluids. Installation is made very simple due to its low weight, integrated capacitor and threaded connection. A double mechanical seal and the large sealing chamber facilitate long maintenance intervals. Direct access to the most important components make maintenance work very convenient. By utilising Wilo-Control switchgears, the Wilo-Padus UNI can also be integrated into existing building management systems.

Description/construction

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

Hydraulics

The outlets on the pressure side are designed as vertical threaded flange connections. Open multi-channel impellers are used as the impeller shape. A strainer is integrated at the hydraulics housing.

Motor

The motors available are surface-cooled motors in single-phase version (with built-in operating capacitor) and three-phase version for the direct starting. The waste heat is given off directly to the surrounding fluid via the motor housing. These motors can operated immersed in continuous duty (S1) and non-immersed in short-time duty (S2) or intermittent periodic duty (S3).

Furthermore the motors are equipped with thermal motor monitoring. This protects the motor windings against overheating. For units with single-phase AC motors this is built-in and switches automatically. I.e. if the motor is switched off due to overheating and then cools down it is automatically switched on again. Bimetallic strips are used for this as standard.

The connection cable has a length of 10 m as standard and is available in following versions:

  • With bare cable ends
  • With plug
  • With float switch and plug

Pump with vertical float switch

The "VA" version is equipped with a vertical float switch. In this version, the switching level is preset by two floaters sitting on a threaded rod. It uses less space than conventional float switches and is perfect for use in tight manholes.

Seal

There is a sealing chamber between the motor and hydraulics. This is filled with medicinal white oil. The unit is sealed on the fluid and on the motor side by mechanical seals.
