KRACHT GmbH products

KRACHT GmbH offers high-pressure external gear motors KM, designed for use under the most demanding operating conditions due to their construction and materials. The primary components include a highly stressed housing and flange cover that are resistant to pressure peaks and continuous vibrations. These gear motors feature a displacement range of 5.5 to 300 cm³ per revolution and can operate within a media temperature range of -20 to 150°C and withstand pressures up to 400 bar. Applications include both mobile and stationary systems such as construction and agricultural machinery, municipal and special-purpose vehicles. Additional options include ATEX versions, motor-pump aggregates, and radial and axial force-absorbing bearing supports. They are suitable for fan and auxiliary drive systems, mobile fluid transport when paired with a pump, and various valve functions enabled by modular design. Noise optimization is also available, with valve options including pressure relief and proportional speed control valves.

The DuroTec gear pumps are primarily designed for multi-component systems in process engineering. Wherever liquids with hard fillers are to be processed, for which standard pumps do not achieve a satisfactory service life, this pump offers a reliable alternative.

The high-pressure gear pump KP, designed by KRACHT GmbH, is primarily utilized in oil hydraulic systems for demanding applications. The key components of the pump include the housing and flange cover, both engineered to be highly resistant to dynamic loads, pressure spikes, and continuous oscillations. This robustness makes the pump suitable for the most rigorous operating conditions. The pump offers a range of displacement from 1.4 to 300 cm³ per revolution and can operate in media temperatures between -20°C to 150°C. It can withstand maximum pressures up to 300 bar. The KP pumps provide options for shaft sealing, notably using radial shaft seals, and come with various valve options including pressure relief valves. Multi-stage configurations of KP pumps, such as combinations with multiple pumps, can achieve high performance while minimizing installation space. These configurations are versatile for use in filtration technology, plastic injection molding machines, press construction, hydraulic systems, hydrosteel engineering, and mobile machinery. The multiple pump versions are hydraulically separated, allow for high cold-start viscosity at high idle speeds, and offer high efficiency across a wide range of rotational speeds.

In the standard version, the housing parts are made of gray cast iron. The gears are made of high-strength case-hardened steel, hardened and mounted in special multi-material bearing bushes. In the standard version, the drive shaft is sealed by a radial shaft seal. All sizes are designed with helical gearing. This, in conjunction with a special gear geometry, results in extremely low noise levels and low pressure pulsation.

The gear type flow meter VC by KRACHT GmbH is designed for high-precision and rugged fluid measurement applications. It delivers standardized and application-optimized solutions for various industries. The VC series includes multiple models tailored for different needs, such as VC with Encoder and VC with IO-Link technology. The VC meters offer wide measuring ranges, from as low as 0.008 l/min to 700 l/min, and can handle media temperatures from -60°C to 210°C, withstanding pressures up to 480 bar. These devices are ideal for applications such as fuel consumption measurement, hydraulic component characterization, gear oil filling, indirect volumetric cylinder displacement measurement, ratio measuring in multi-component dispensing systems, small quantity measurement, and micro-dosing. The accuracy and robustness of these meters make them suitable for demanding environments, providing reliable performance in process technology, hydraulics, marine, and renewable energy sectors.

The KRACHT SVC screw spindle flow meters exemplify durability, precise measurement accuracy, easy handling, and long-lasting economic benefits. Designed to withstand contamination and insensitive to pollution, these flow meters offer pulsation-free operation and low flow resistance. The SVC series includes models with encoders for maximum measurement resolution, ideal for process and test stand applications, and those featuring IO-Link technology for better integration. The measurement ranges from 0.4 to 3750 l/min with a medium temperature range of -40 to 210 °C, handling a maximum pressure of up to 480 bar. An efficient and precise solution for various applications across hydraulic systems, process technology, and more, the SVC flow meters are integral to fluid measurement tasks requiring high reliability and performance.

The measuring mechanism of the KRACHT Volume counter VCL0.1 for painting technology consists of a pair of gear wheels driven by fluid flow in accordance with the principle of operation of a gear motor. The measuring mechanism bearing system comprises radial and axial bearings. The sensor system is separated from the measuring compartment; there is no contact with the medium. The motion of the gear wheels is scanned by a magnetoresistive sensor. The KRACHT VCL0.1 Volume counter are supplied with gear wheels and bearings coated with a hard material surface. An Explosion proof versions for the VCL0.1 is available.
