FREQUENTLY ASKED QUESTIONS

Technical Specifications:

Q: What material is utilized for the dynamic sealing element in the MRF-E series to reduce friction?

A: The sealing material is a PTFE-Compound, providing low stick-slip effect and good sliding properties.

Wiring & Installation:

Q: What is the maximum voltage and current capacity for the electrical slip ring conductors on the MRF-E?

A: The electrical slip ring supports up to 250 V AC/DC and currents up to 4 A per conductor.

Troubleshooting & Compatibility:

Q: Is the MRF-E suitable for use with high-pressure steam at its maximum stated temperature of 90 degrees C?

A: The MRF-E is compatible with water, air, hydraulic oil, and nontoxic gases up to 90 degrees C, but not steam.

Replacement & Upgrades:

Q: If only fluid transfer is needed without electrical signals, what similar Haag + Zeissler series is recommended?

A: The MRF series offers similar fluid passage capabilities without the integrated electrical slip ring component.
