Does the Rotary nozzle for sewer cleaning without centric hole + side holes, type RM require special maintenance due to its stainless steel body and brass rotor when used up to 150 bar?

The Rotary nozzle for sewer cleaning without centric hole + side holes, type RM does not require special maintenance solely because of its stainless steel body and brass rotor when used up to 150 bar, provided normal operating and care practices are followed. Stainless steel housing offers good corrosion resistance and brass rotor tolerates pressures up to the specified 150 bar, but to ensure reliable performance and long service life you should: - Rinse the nozzle after use with clean water to remove debris, grit and chemicals from sewage. - Inspect and clean the side holes regularly to prevent clogging that would impair rotation and flow. - Check the rotor for smooth rotation; disassemble and clean if rotation becomes rough or noisy. - Avoid dry-running and protect from abrasive solids; heavy abrasive use will increase wear on brass rotor and holes. - Use appropriate thread sealing on the GW 1/4" BSP connection and check for leaks; tighten to recommended torque. - Store in a dry, clean place to limit corrosion of any non-stainless parts and reduce fouling. If the nozzle is exposed to aggressive chemicals, extreme temperatures, or very abrasive solids, consider more frequent inspection and maintenance or consult the manufacturer for compatibility and spare-part recommendations.

Can Rotary nozzle for sewer cleaning without centric hole + side holes, type RM be used with standard 1/4" BSP hoses at pressures up to 150 bar?

Yes. Rotary nozzle for sewer cleaning without centric hole + side holes, type RM can be used with standard 1/4" BSP hoses at pressures up to 150 bar. The nozzleâs connection is GW 1/4" BSP and its rated working pressure is up to 150 bar, matching the hose specification. Ensure hoses, fittings and pump system are also rated for 150 bar, all threads are properly sealed, and safe operating practices are followed.

Is Rotary nozzle for sewer cleaning without centric hole + side holes, type RM compatible with other metal fittings at 150 bar?

Yes. the Rotary nozzle for sewer cleaning without centric hole + side holes, type RM is compatible with other metal fittings at 150 bar, provided those fittings use a matching GW 1/4" BSP connection and are rated for at least 150 bar. The nozzleâs construction (stainless steel body and brass rotor) is suitable for high-pressure use, and its 19 mm diameter fits typical line sizes for this connection. Before connecting, verify: the mating fittingâs thread (GW 1/4" BSP), its pressure rating (â¥150 bar), proper sealing (use appropriate PTFE tape or seal), and that the assembly materials are compatible with your fluid and operating conditions. If any fitting or adaptor is rated below 150 bar or uses a different thread standard, do not use it.
