Mobile Pump Units for use on the event of Pipeline Damage

Problem Description

Our customer (a utility network) requires a solution for repairing pipes in the district heating network that is characterized by rapid operational readiness and high reliability. The mobile pump unit must function smoothly under demanding circumstances such as in residential areas and in different weather conditions. The following requirements were therefore defined:

Rapid deployment: The unit must be mobile and quickly ready for use at all times in order to be able to repair pipe damage swiftly.

Mobility: The solution must be mounted on a trailer and be easy to transport so that it can be moved flexibly from site to site.

Robust unit: The system is designed to be particularly robust and resistant in order to withstand the stresses of different operating environments.

Weatherproof: Whether rain, snow or extreme temperatures - the pump unit must be suitable for operation in all possible weather conditions.

Continuous operation: As repairs often run for long periods of time, the unit must be designed for long-lasting and continuous operation.

Residential areas: The unit should be able to be operated in sensitive settings such as residential areas, which is why low-noise and low-emission solutions are particularly important.

Our mobile pump solution meets all these requirements and ensures that the district heating supply is restored quickly, reliably and efficiently.


VN Pumpen Solution

Our mobile pump unit is specially designed for fast and reliable use in the event of pipeline damage. The robust design and sophisticated equipment ensure maximum efficiency and flexibility in emergency situations.

At the heart of the unit is a powerful horizontal centrifugal pump, driven by a reliable diesel engine. For maximum user-friendliness and safety, the system can be switched on & off via the built-in monitoring panel using a lifting magnet.

Further highlights of the mobile pump unit:

  • Integrated refueling box for continuous operation

  • Battery charger for use in all conditions

  • Mounted on a sturdy central axle trailer for maximum mobility

  • Exhaust silencer on the roof to minimize noise pollution

The mobile pump unit complies with all regulations and is approved in accordance with TÜV §13 EG FGV, which ensures smooth operation on the road. Put your faith in our many years of experience in system construction and the manufacture of high-quality pump solutions - your reliable choice for any emergency situation!
