Technical Details: Kracht KF5/250 H30B

 Key Features

1. Bi-Directional Input Protection: The KF5U07 Universal Valve is built-in for constant delivery to the same pressure port, irrespective of the direction of the shaft rotation.
2. Low Noise Helical Gearing Optimized gear shape decreases pressure waves, cavitation risk and structural noise during high-throughput operation.
3. High Displacement Performance: Offers a nominal displacement of 250cm/ rev to provide fast transfer of oil volume under normal operating pressures.
4. Extreme wear resistance for tough situations Heavy-duty Grey/Spheroidal Cast Iron Housing with Case Hardened Steel Gears.

Chief Engineer’s Installation Checklist:

Universal Valve Bleeding: The KF5U07 Universal Valve relies on precise hydraulic pilot routing to shift its internal directional gates. During the initial priming phase, ensure the pump casing is filled manually with system oil via the suction port to prevent dry running of the multi-material plain bearing bushes.

Alignment Tolerances: When coupling to an electric motor, check angular and parallel alignment using a dial indicator or laser tool. Misalignment will induce premature wear on the single radial lip-type shaft seal, causing external oil leakage or air ingestion under vacuum.

Frequently Asked Questions

What does the Kracht Universal Valve (KF5U07) do?

The KF5U07 Universal Valve is a specialized directional regulation block. It ensures that regardless of whether the pump shaft rotates clockwise or counter-clockwise, the inlet and discharge ports do not switch. Fluid continues to discharge from the designated pressure side without manual piping modifications.

Can this pump handle high-viscosity lubricants?

Yes, the Kracht KF external gear series is designed for heavy media transfer, including high-viscosity marine gear lubricants and diesel fuels. Ensure operating speeds match the viscosity curve to avoid cavitation.

What is the maximum pressure rating for the Kracht KF5/250?

This pump is rated for a maximum pressure threshold of 25 bar (363 psi), assuming the fluid parameters fall within the recommended temperature and viscosity thresholds.
