Technical Specifications

Installation Guide

The following steps outline a typical installation procedure for the VP5 160928 pump head:

1. Preparation: Turn off the boiler and allow the system to cool. Drain any remaining water from the circulation loop.
2. Removal of Old Pump Head: Unscrew the existing pump head using a suitable wrench, taking care not to damage the pipe threads.
3. Cleaning: Inspect the pipe ends for corrosion or debris. Clean with a soft brush and apply a thin layer of anti‑seize compound if recommended by the manufacturer.
4. Installation: Align the new VP5 160928 pump head with the pipe threads, hand tighten initially, then secure with a torque wrench to the specified value (typically 12 Nm).
5. Sealing: Apply PTFE tape or a suitable sealant on the male threads to prevent leaks.
6. Re‑filling and Testing: Refill the system with water, purge air from the loop, and restore power to the boiler. Monitor for proper operation and check for any abnormal noise or vibration.

Maintenance Tips

• Regularly inspect the pump head for signs of wear or corrosion, especially in areas with high humidity.
• Ensure that the boiler’s pressure gauge remains within the recommended range to avoid over‑pressurizing the pump head.
• Clean the inlet and outlet ports periodically to prevent sediment buildup, which can reduce flow efficiency.
• Replace any damaged or worn seals promptly to maintain leak‑free operation.

Applications

The VP5 160928 is ideal for:

• Residential heating systems with Turbomax Plus boilers.
• Commercial buildings utilizing Thermocompact or VU/VUW boiler units.
• Retrofit projects where a reliable, low‑noise pump head is required to upgrade older heating circuits.
