STM JET 4200.45 is the new all-rounder among high-pressure pumps

A waterjet cutting system is only as good as its high-pressure pump. STM has therefore now developed a high-pressure pump that plays all parts. The focus hereby was on performance, energy efficiency and minimum pressure fluctuations.

Eben. The basic idea of STM to adjust waterjet?cutting systems to the needs of customers organically and modular in order to thus cut even more economically and efficiently is demonstrated also by the latest development of the waterjet cutting systems manufacturer. The newly developed STM JET high-pressure pump 4200.45 with a maximum operating pressure of 4000 bar and a feed rate of 4.6 l/min convinces with more power, less wear and high energy efficiency. Special attention was paid to consistent pressure for top cutting quality. An upgrade in terms of functionality is provided by the optional PressureSaver® pressure reduction unit for customized high-speed pressure adjustment for all individual connections.

More cutting capacity with less energy consumption

With a power of 45 kW for 0.40 mm water nozzles, the new pump provides up to 35 % more cutting capacity (compared to 37 kW) thanks to the XL pressure intensifier. The longer stroke ensures 20 % less double strokes and thus longer service lives for seals and check valves – with the same cutting capacity. That protects the entire high-pressure system.

The subject of energy efficiency is pertinent not only for investment grants. Because of the frequency-inverter-actuated asynchronous motor, the STM JET 4200.45 requires 20 % less current for regular operation and is thus clearly more economical than comparable units. A lower holding current with closed cutting valve and only 1.5 times the start-up current round out the energy efficiency package.

Higher cutting speed through low pressure fluctuations

The actual current display ensures consistent pressure control; stepless pressure adjustment is possible from the STM SmartCut waterjet cutting software. Pressure fluctuations are only 50 bar or 1.25 % – which not only protects high-pressure components but also increases the cutting speed by 10 %. For comparison: with conventional pumps, the pressure fluctuates about 120 bar or 3 %.

In terms of functionality, the STM JET high-pressure pump offers a few highlights. Low pressure and high litre capacity enable surface abrasion and engraving. The pump is also suitable for suspension jet cutting. The standard package already contains a booster pump, an automatic-stop valve, one oil filling, special tools and a spare parts package. For professional users, there is also an optional PressureSaver® pressure reduction unit. This individual high-speed pressure adjustment enable immediate switches from low to high pressure after every piercing.

STM is a leading provider of waterjet cutting systems with its head office in Eben, Austria and Schweinfurt, Germany. For more than 25 years, the traditional company has developed future-proof production solutions, mainly for the steel, aluminium, metal, plastic, stone and glass industries, which are most notable for their efficiency, ease of use and resistance to wear. Alongside future-proof technology and quality as standard, STM places great emphasis on innovative full service. In so doing, the brand manufacturer ensures that its individual manufacturing processes are continually matched to the latest requirements of its customers.

STM Waterjet Germany, formerly Maximator JET, has been the development and sales location in Germany since 1999. The company focuses on developing and realising highly specialised waterjet cutting systems for all kinds of special applications here. The company STM stands for pioneering production solutions and unlimited individualization options.
