An upgraded Jung Pumpen U5 drainage pump is arriving from September 2026 – combining everything installers know and trust about the U5 with new features designed to improve convenience, efficiency and operational reliability.
At Pump Technology, we’ve worked with Jung Pumpen products for many years, and the U5 has long been one of the dependable workhorses within the drainage pump range.
From 1 September 2026, Jung Pumpen is introducing an updated U5 K and U5 KS, retaining the proven characteristics of the existing pump while adding several useful improvements.
What’s new on the Jung Pumpen U5?
The updated U5 features:
- Lockable flushing device
- New ergonomic handle
- Fluid temperature capability of 35°C, with temporary operation at temperatures of up to 60°C for 10 minutes
These improvements add to an already versatile drainage pump designed for both fixed and mobile applications.
One pump, plenty of applications
For permanent installations, the U5 K and U5 KS can be installed in sumps and lifting stations and used for wastewater from domestic appliances including washing machines, dishwashers and sinks. In stationary applications, the installation can also provide backflow protection for the building.
For mobile use, it’s equally at home dealing with water from flooded basements, garden ponds, laundry rooms and drainage pits.
And when you want to get as much water out as possible, the removable strainer allows shallow suction down to a residual water level of approximately 5mm.
Built for reliable everyday operation
The new U5 continues to offer some of the features that have made the range such a useful option for installers and building operators:
Continuous S1 operation is possible thanks to motor jacket cooling, while GID technology helps provide high operational reliability. The pump offers 10/20mm free passage and is available with or without automatic switching and with either a 4m or 10m cable.
And, of course, it continues to be Made in Germany, maintaining the build quality and durability associated with Jung Pumpen.
Easier installation and maintenance
The U5 can also be combined with Jung Pumpen guide rail systems to make future pump removal and maintenance quicker and easier.
For a straightforward installation, the Easyfix 32 installation sets are supplied pre-assembled and ready to connect, with options for both single and duplex installations.
The Jung Pumpen Floodbox will also feature the new U5 going forward.

The new Jung Pumpen U5 range becomes available from September 2026, replacing the current U5 models.
