Holzhauer-Pumpen was significantly involved in developing the idea of supplying pump units in compact design more than 30 years ago. Ever since, we have succeeded in achieving the highest level of perfection for this design, which has enabled us to defend our technological leadership against the competition.

Noise has a negative effect on both the entire body as well as on our health. Diesel fire pump units are loud and subject to intense vibrations due to their design – thanks to our SCHALLEX system and other provisions, such as encapsulation of the entire unit, we have managed to reduce vibrations and noise down to a minimum.

We supply ready-to-operate and ready-to-connect emergency power units, also as prefabricated stations and also noise-reduced. On request, the units can be equipped with intake and exhaust air silencers for a surge load capacity of up to 800 kVA or are manufactured in compact design with coordinated controller and mains switching.

Some fires can only be extinguished with special agents, which also include foam solutions. Precision proportioning systems and special pumps are required to produce effective extinguishing foam. We design, manufacture and supply approved foam concentrate pump units for all types of foam concentrate and all commercially available viscosities.

Further information about our foam extinguishing technology

For systems with water withdrawal processes from surface water or rivers. Available in all required sizes and designs, also foldable and lockable for cleaning purposes.

Possible materials:

Hot-dip galvanised steel according to DIN EN ISO 1461
Stainless steel V2A
Stainless steel V4A

We calculate and design the intake screen as well as the complete intake structure for you!
