Heating Pump Seal Replacement – Coastal College

Client: Coastal College
Location: UK (Seaside Area)
Service: Mechanical Seal Replacement & Pressurisation Unit Reinstatement
Industry: Education / Facilities Management

The Challenge

NT Cloke was called out to a college located near the coast after several heating pumps ran dry. The issue was traced back to a bypassed pressurisation unit, which allowed the system to continue operating under low-pressure conditions, causing seal failure and risking long-term pump damage.

Our Solution

Our team responded promptly and carried out a comprehensive on-site fix:

✅ Replaced 10 mechanical seals across the affected heating pumps
✅ Fully tested all pumps to confirm leak-free operation
✅ Reinstated the pressurisation unit to restore proper pressure control
✅ Ensured the system was now running safely and efficiently

Results

✅ Dry running prevented
✅ Full pressure protection reinstated
✅ Safer, longer-lasting heating system
✅ Ongoing reliability for campus heating infrastructure

With one call, NT Cloke delivered a full, lasting fix—no more link-outs, no more surprises.
