Case Study: Secondary Twin Circulation Pump Replacement at Avant Garde

Client: Edmund Services

Location: London, Avantgarde

Service: Secondary Twin Circulation Pump Replacement

Date: August 2025

Background

Alpha Pumping Solutions was commissioned to replace a faulty secondary twin circulation pump set at the Avant Garde development. The existing unit, a Grundfos TPED 65-24, had reached the end of its operational life, leading to reduced system reliability and performance. We sought a modern, energy-efficient replacement that would enhance overall system efficiency and ensure consistent circulation performance within the building’s HVAC system.

Challenges

The replacement project presented two key challenges:

• Restricted plantroom space: The pump was installed within a compact area, requiring precise handling, and planning to safely remove the old unit and position the new one.
• Heavy equipment handling: Due to the weight of the pump, careful coordination and appropriate lifting equipment were necessary to carry out the installation without disrupting surrounding systems or compromising safety.

Alpha Pumping Solutions’ engineering team carried out detailed risk assessments and used specialist lifting techniques to manage both space and weight constraints effectively.

Solution

The team installed an upgraded version of the Grundfos twin circulation pump, providing improved flow performance, higher energy efficiency, and compatibility with modern control systems. The installation included precise alignment, pressure testing, and commissioning to ensure seamless integration into the existing system.

All works were completed with minimal downtime to building operations. Alpha Pumping Solutions’ engineers followed strict health and safety procedures throughout the installation process, ensuring a safe and efficient delivery.

Results

Following completion, the new pump system delivered:

• Improved efficiency — enhanced motor and control design reduced energy consumption.
• Lower operational costs — better system performance contributed to long-term energy savings.
• Enhanced reliability — the new pump ensures stable and consistent system pressure and flow.
• Up-to-date technology — the upgraded pump meets current performance standards and sustainability expectations.

The client expressed satisfaction with the professionalism of the installation and the noticeable improvements in system operation.

Conclusion

This project demonstrates Alpha Pumping Solutions’ expertise in managing complex mechanical installations in challenging environments. Through careful planning, skilled execution, and technical knowledge, the team successfully delivered an efficient and modern pumping solution for Avant Garde — reinforcing Alpha Pumping Solutions’ commitment to quality, reliability, and innovation.

Case Study: Foul Water Pumping Station Cleaning

Client: Edmund Services

Location: London, Hallsville Quarter

Service: Cleaning and Maintenance of Foul Water Pumping Station

Date: September 2025

Background

Alpha Pumping Solutions was appointed to carry out a comprehensive clean of a foul water pumping station as part of the client’s planned maintenance programme.
Over time, the wet well had accumulated debris, grease, and sediment build-up, which was beginning to impact pump efficiency and risk potential blockages. To prevent system failure and ensure reliable operation, a full clean and waste removal was scheduled.

Challenges

The project required careful planning and execution due to:

• Confined space entry: The foul water chamber required safe entry and ventilation procedures.
• Odour and contamination risks: The nature of the work demanded strict hygiene controls and appropriate PPE.
• Limited access: The pumping station’s location required the use of specialised hose extensions and positioning of the tanker in a restricted area.

Health and safety were a top priority throughout the works, with risk assessments, method statements, and confined space permits in place.

Solution

Alpha Pumping Solutions deployed a micro vacuum tanker unit and a large vacuum tanker to remove accumulated waste, sludge, and debris from the wet well.
The process involved:

• Isolating and safely shutting down the pumping system
• Removing residual foul water using a high-capacity vacuum tanker
• Manual cleaning of the wet well walls and base to remove grease and silt.
• Jet washing internal surfaces and pump components
• Inspection of pipework, valves, and float switches to ensure full operational integrity.
• Safe transport and disposal of all waste material at an approved treatment facility

The team ensured that all work was completed efficiently, minimising downtime, and restoring the pumping station to optimal condition.

Results

Upon completion, the pumping station was fully cleaned, inspected, and recommissioned. Key outcomes included:

• Improved pump performance and reliability
• Reduced risk of blockages or system failures
• Compliance with environmental and maintenance standards
• Extended equipment lifespan through proactive maintenance

The client was highly satisfied with the swift, safe, and thorough delivery of the works, commending Alpha Pumping Solutions for their professionalism and efficiency.

Conclusion

This project demonstrates Alpha Pumping Solutions’ ability to deliver specialist pumping station maintenance safely and effectively.
By combining skilled engineers, appropriate equipment, and rigorous safety procedures, the team successfully completed the cleaning of the foul water pumping station — ensuring ongoing system reliability and environmental compliance.

Case Study: Cold Water Booster Set Installation

Client: Edmund Services

Location: 68 Hammersmith Road

Service: Cold Water Booster Set Installation

Date: July 2025

Background

Alpha Pumping Solutions was appointed to carry out the installation of a new cold-water booster set to improve water pressure and flow throughout the building’s domestic water system. The existing setup was unable to maintain consistent pressure during peak demand periods, leading to performance issues across multiple outlets.

The client required a reliable, energy-efficient, and future-proof solution to ensure stable water supply for the entire property.

Challenges

The project presented several logistical and technical challenges, including:

• Limited plantroom access: The booster set, and associated components had to be carefully manoeuvred into a confined space without disruption to surrounding services.
• Maintaining water supply: Work had to be completed within a tight schedule to minimise downtime and maintain water availability for occupants.
• System integration: The new booster set needed to integrate seamlessly with the existing pipework, control system, and pressure settings.

Solution

Alpha Pumping Solutions supplied and installed a modern variable-speed cold water booster set, designed to automatically adjust pump speed based on demand, ensuring efficient operation and reduced energy consumption.

The installation process included:

• Safe removal of the existing system
• Installation of the new booster set, including pipework modifications and isolation valves.
• Electrical connection and control panel integration
• System commissioning, testing, and calibration to achieve optimal pressure settings.

All works were carried out in accordance with current water regulations and the client’s operational requirements.

Results

The newly installed booster set delivered immediate performance improvements, including:

• Consistent water pressure across all outlets, even during peak demand
• Improved energy efficiency through variable-speed drive technology
• Reduced maintenance requirements thanks to high-quality components and modern controls
• Enhanced reliability and system monitoring with intelligent fault diagnostics.

Feedback from the client was highly positive, praising the professionalism of the installation team and the noticeable improvement in water system performance.

Conclusion

This project highlights Alpha Pumping Solutions’ expertise in water system upgrades and mechanical plant installations. Through careful planning, technical precision, and efficient execution, the team delivered a robust and energy-efficient cold water boosting solution that ensures reliable performance for years to come.
