Kracht

Kracht is a leading German company that has specialized for more than 50 years in the development and production of precision fluid measurement equipment and hydraulic components. The company is globally recognized as a specialist in gear flow meters and gear volume meters for industrial fluid measurement and lubrication. Kracht products are used in the most demanding industrial environments, where precise fluid measurement and reliable hydraulic components are critically important.

The extensive Kracht product program includes gear flow meters for measurement and control purposes, gear volume pumps for lubrication and hydraulic systems, shaft seals and couplings for power transmission. The Kracht flow meters are available for measuring ranges from a few milliliters to hundreds of liters per minute and can be used with a wide range of fluids, from mineral oils and hydraulic fluids to chemical media. The products are available in stainless steel, aluminum and special alloys for compatibility with aggressive media.

Kracht electric motors and drive systems form another important part of the product portfolio. The Kracht TF series electric motors are specially designed for use in combined motor-pump units in hydraulic systems. These motors are available in power ranges from a few kilowatts to more than 200 kilowatts and are available in versions for standard and potentially explosive environments.

Verkopershulp.nl supplies the complete Kracht range, including gear flow meters, hydraulic gear volume pumps, electric motors (TF series), couplings, lip shaft seals and spare parts. Most products are directly available from our European stock for fast delivery to industrial customers in the Netherlands, Belgium and Europe.

Kracht products are configured based on the customer's specific process parameters. Verkopershulp.nl offers extensive technical support for product selection, taking into account the medium to be measured or transported, the desired measurement accuracy, pressure and temperature conditions and installation possibilities.

Kracht has also developed specialized measurement instruments for measuring viscous media, including lubricating oils, gear oils, and high-viscosity polymers. The KF series Kracht gear meters are available with special housings for direct mounting in piping systems with connection pressures up to 630 bar, and are available with digital pulse output, frequency output, and analog 4-20 mA output for easy integration into automation systems.

For the maritime industry and offshore applications, Kracht supplies measurement equipment certified by recognized ship classification societies such as DNV GL, Lloyd's Register, and Bureau Veritas. This certified measurement equipment is essential in fuel management systems on board ships and offshore platforms where precision fuel measurement is legally required. Verkopershulp.nl advises you on the correct Kracht measurement equipment for your specific application and medium properties.

Frequently Asked Questions

Which fluids can be measured with Kracht gear flow meters? ▾
Kracht gear flow meters are suitable for a wide range of fluids, including mineral oils, hydraulic fluids, fuel, vegetable oils, chemical solvents and aqueous fluids. The meters are available in stainless steel (316) and special versions for aggressive media. The viscosity range runs from 0.5 mm²/s to more than 1000 mm²/s.
What is the measurement accuracy of Kracht flow meters? ▾
Kracht gear flow meters achieve measurement accuracy of ±0.5% to ±0.1% of the measured value, depending on the model and fluid viscosity. This makes them particularly suitable for precise dosing, batch measurement and calibration applications. Verkopershulp.nl supplies the flow meters with manufacturer calibration certificate on request.
Are Kracht TF series motors suitable for use with a frequency inverter? ▾
Yes, the Kracht TF series electric motors are available in versions suitable for drive with a frequency inverter (VFD). This enables speed and pressure control of hydraulic systems. When using with a frequency inverter, ensure adequate motor cooling, as ventilated motors generate less cooling at low speeds.
How do I order a Kracht flow meter for my specific application? ▾
When ordering a Kracht flow meter, the following data are needed: the medium to be measured, the desired measuring range (min/max flow in l/min), working pressure and temperature, desired connections, the desired output signal (pulses or analog 4-20 mA) and housing material. Our technical team helps you with the correct configuration.
Does Verkopershulp.nl also supply spare parts for existing Kracht installations? ▾
Yes, Verkopershulp.nl supplies spare parts for Kracht fluid measurement equipment and hydraulic pumps, including shaft seals, seal kits, replacement gears and electronic pulse transmitters. Provide the Kracht model number and serial number for quick identification of the correct parts.
Can Kracht hydraulic pumps be used in ATEX-certified environments? ▾
Kracht supplies special versions of hydraulic pumps and flow meters with ATEX certification for use in potentially explosive environments. These products carry ATEX approval in accordance with European Directive 2014/34/EU. Verkopershulp.nl can specify which products are available in ATEX version.
What are the maximum pressure and temperature values for Kracht flow meters? ▾
Most Kracht gear flow meters are available for working pressures up to 400 bar and temperatures up to 150°C. Special versions are available for higher pressure and temperature conditions. Verkopershulp.nl advises you on the available configurations based on your process conditions.
