Rapid Response & Energy Savings for NHS Hospital Pump System
The Challenge
Our client, a 600-bed NHS district hospital was proactively engaging with us to explore options for replacing their ageing and inefficient pump systems within their facility, aiming to reduce energy consumption and operational costs.
This plan became critically urgent when a vital heating pump failed within their busy Accident & Emergency (A&E) department. This posed an immediate risk to patient care and facility operations.
The Solution
- Emergency Intervention: We responded immediately, arriving on-site within hours to implement a temporary fix (‘limp mode’) for the failed A&E pump, ensuring continued operation. This incident highlighted the system’s vulnerability and accelerated the need for a comprehensive upgrade.
- Accelerated Upgrade Project: The A&E failure served as a catalyst, escalating the priority of the full system upgrade. We quickly moved forward with replacing the outdated pumps in critical areas, including Radiotherapy, Oncology, A&E, and the main public facilities.
Project Scope & Execution:
The project involved replacing multiple outdated pump sets with modern, high-efficiency Grundfos technology. For each system replacement, our team performed:
- Decommissioning and removal of legacy pumps.
- Installation of new state-of-the-art, energy-saving Grundfos pump systems.
- Precision pipework modifications between the new pumps and existing isolation valves.
- Fabrication and installation of custom base plates to ensure correct height alignment with existing pipework.
- Complete mechanical and electrical integration.
- Comprehensive testing and commissioning of each new pump and associated inverter drive.
Specific Pump Replacements:
- Legacy 1.1kW Belt Drive Pumps were replaced with 0.75kW Grundfos End Suction Direct Drive models.
- Legacy 0.75kW Belt Drive Pumps were replaced with 0.55kW Grundfos End Suction Direct Drive models.
- Legacy 11kW Starflex Pumps were upgraded to 7.5kW Grundfos NBE 80 Inverter-Driven End Suction pumps, including new expansion bellows and pressure transducers.
- Legacy 1.5kW Belt Drive Pumps were replaced with 0.55kW Grundfos TP Direct Drive models.
The Outcome
This comprehensive overhaul delivered significant advantages:
- Significant Energy Savings for NHS Hospital: Total annual energy consumption was reduced by over 51%, dropping from 113,091.60 kWh to 55,371.96 kWh – an annual saving of 57,719.64 kWh. The inverter technology on circulator pumps alone contributed savings of 68%.
- Rapid Return on Investment: The energy cost savings result in a project payback period of just 3.28 years.
- Reduced Carbon Footprint: Lower energy consumption directly contributes to the hospital’s environmental goals.
- Enhanced Reliability: New, modern pumps significantly reduce the risk of unexpected failures and downtime.
- Quieter Operations: Reduced plant room noise levels.
- Futureproofing: All new pumps and installation work are covered by a 24-month warranty with spare parts guaranteed for 10 years.
This project demonstrates our ability to respond rapidly to critical failures while delivering long-term energy efficiency and operational improvements for essential healthcare facilities.
Key Points
- Energy savings for NHS Hospital – resulting in an annual saving of 57,719.64 kWh for our customer.
- Return on investment – quick payback of 3.28 years.
- Enhanced reliability – modern pumps = less failures and downtime.
