Driven by the idea of wisely and efficiently using the mechanical properties of streaming water, and thanks to continuous research and development, Woma provide systems delivering pressures in excess of 4,000 bar – this is quadruple the pressure at the deepest point of the ocean!
With almost 50 years experience Woma have been the cutting-edge manufacturer providing innovative products to the high-pressure water jet industry.
Regardless of the application – be it removal, cleaning or cutting – Woma design and manufacture high-precision power packs, which set benchmarks in terms of quality, reliability, cost-effectiveness and customer satisfaction.
The highly compatible modular system is what gives our systems such a wide range of applications and flexibility.
-
Depending on the nozzle design, you can cut, demolish, deburr, remove paint and coatings, or decontaminate.
-
Depending on the power output you can achieve pressures of up to 4,000 bar (43,500 psi).
-
We can deliver stationary or mobile units driven by either electric motors or internal combustion engines to suite any application area.

1500 bar ultra high pressure cleaners:

WOMA cold and hot water systems up to 1500 bar cover a wide range of applications.
They are specialists for medium to heavy concrete removal,paint removal,cleaning ...
Using the operating pressures of up to 1500 bar and volumetric flow rates of up to 605 l/min, this line provides ideal tools for cleaning tanks, sewage systems, pipes with big volumes, and much more.
The pressure and rotation speed control provides for a long service life with minimal fuel consumption.
Our systems up to 3000 bar combine very high operating pressures with a low-wear design.Using the operating pressures of up to 3000 bar and volumetric flow rates of up to 200 l/min:
Hot water ultra high pressure cleaners:

In many applications,the use of hot water is particularly efficient.
The Hotbox 350/500 is an ideal completion for our hot water devices.
The high-quality mobile burner secures the required water temperature. The easy-to-maintain compact devices are characterized by a high safety standard.
Ideal for the use in cleaning facades, buildings, industry buildings, and much more.
For operating pressures up to 4,000 bar (43,500 psi) contact us for our Millennium-line of Ultra high-pressure plunger pumps with HCV®-technology, or our ARP®-line for use with abrasive contaminated water, or our Y-line of compact pumps.
ARP® ultra high pressure cleaner pump

This series was specially developed for pumping water that is contaminated with granular or fibrous solids.The ARP®-high-pressure
plunger pumps have operating pressures up to 5800 psi/400 bar and volumes up to 1700 l/min1) and always work reliably with fluids containing abrasives.
Differing from other pumps in this rating class, this series is designed for suction flow temperatures up to 65°C – a temperature resistance that can be flexibly increased to up to 90°C*.
You can vary the rating parameters through a simple replacement of the interchangeable plunger set; this is possible due to the modular design of the pump.The pump satisfies both the ATEX as well as the API standard** and has gearbox cooling. An auxiliary drive shaft allows additional flexibility, by allowing the addition of a second pump to the drive train, thus doubling the output. The pumps of the ARP®-series have been developed as slow-speed pumps. For you, this means partic - ularly long life and longer operation between maintenance cycles.
* optional, ** pressure-dependent and volume flow-dependent
Y-Line 1000 bar ultra high pressure cleaner pump

The high-pressure plunger pump of the Y-series is especially compact.With operating pressures up to 14500 psi/1000 bar, this type is the most powerful in its class; it has been developed for concrete removal projects, stripping of coatings or cleaning of tube bundles.
These pumps have an auxiliary shaft end that can be used to connect a second pump, so that you can double the output in no time at all.
The modular design gives you additional flexibility because all you have to do to vary the output characteristics is to change the interchangeable plunger set.
The pump, which can be delivered in keeping with the ATEX and API standards* has gear box cooling and being a slowspeed pump, is low wear and offers long life between maintenance cycles. In contrast to other, comparable pumps in this class,it can withstand suction flow temperatures up to 65°C or 90°C** with out any problem.
* pressure-dependent and volume flow-dependent, ** optional
