Project Overview

NT Cloke Pumps & Water recently completed a twin booster pump replacement project, upgrading an ageing water pressure boosting system with two new Grundfos vertical multistage pumps.

The existing booster pump installation required replacement, and our engineers were tasked with removing the old equipment, installing the new pumps and ensuring the complete system operated correctly.

Working within the existing plant room, our engineers installed the replacement Grundfos pumps, completed the necessary electrical connections and carried out comprehensive testing and commissioning.

The completed installation provides a fully operational twin booster pump system designed to maintain the required water pressure and support reliable water distribution throughout the property.

The Challenge

Replacing an Ageing Twin Booster Pump System

Booster pump systems play an essential role in maintaining adequate water pressure in residential, commercial and industrial buildings.

Over time, ageing pumps can become less reliable, potentially leading to reduced performance, increased maintenance requirements and unexpected breakdowns.

In this project, the existing twin booster pump installation required upgrading.

Our engineers needed to remove the ageing pumps while retaining the existing system infrastructure wherever suitable.

The plant room contained pipework, pressure vessels and other mechanical equipment, making careful planning and installation essential.

The main requirements included:

• Removing the existing twin booster pumps.
• Installing two new Grundfos vertical multistage pumps.
• Connecting the replacement equipment to the existing system.
• Completing electrical wiring and connections.
• Checking pressure and vessel settings.
• Configuring pump sequencing and controls.
• Testing both pumps individually and together.
• Ensuring the complete system was operating correctly.

The objective was to deliver a reliable replacement booster pump installation while making effective use of the existing plant room arrangement.

The Solution

Installation of Two New Grundfos Vertical Multistage Pumps

Our engineers removed the existing booster pumps and installed two new Grundfos vertical multistage pumps.

Grundfos is a leading manufacturer of pumping equipment, with vertical multistage pumps widely used in water pressure boosting applications.

These pumps are designed to provide efficient, reliable water pressure for a range of building services applications.

The replacement units were securely installed and connected to the existing system.

Our engineers then completed the electrical connections and prepared the equipment for commissioning.

Twin Booster Pump Installation Works

The project included:

✅ Existing Pump Removal – The ageing booster pumps were disconnected and removed.

✅ Grundfos Pump Installation – Two new Grundfos vertical multistage pumps were installed.

✅ Mechanical Connections – The replacement pumps were connected to the existing pipework and booster system.

✅ Electrical Installation – Electrical wiring and connections were completed.

✅ System Filling & Venting – The system was filled and the pumps vented in preparation for operation.

✅ Pump Sequencing – The controls were configured to support the correct operation of the twin pump arrangement.

✅ Pressure Settings – System pressure and vessel settings were checked.

✅ Commissioning – Both pumps were tested individually and together to confirm correct operation.

The completed installation was thoroughly tested before being returned to service.

Testing & Commissioning

Ensuring Reliable Twin Booster Pump Operation

Installing new booster pumps is only part of the process.

Correct commissioning is essential to ensure the equipment operates safely, efficiently and in accordance with the system’s requirements.

Following installation, our engineers carried out operational testing on both Grundfos pumps.

Each pump was tested individually before the complete twin booster arrangement was assessed.

Pump sequencing and control settings were checked to ensure the system responded correctly during operation.

Pressure settings were also verified, alongside the associated pressure vessel configuration.

Commissioning checks included:

• Individual pump operation.
• Combined twin pump operation.
• Pump sequencing and controls.
• System pressure performance.
• Pressure vessel settings.
• Electrical connections.
• General operational performance.

Following commissioning, the system was confirmed to be maintaining the required pressure and operating correctly.

The Result

A Fully Operational Grundfos Twin Booster Pump System

The completed project successfully replaced the ageing booster pump equipment with two new Grundfos vertical multistage pumps.

The replacement installation was integrated into the existing system, with all necessary electrical connections, pressure checks and commissioning completed.

Both pumps were tested independently and as part of the complete twin booster arrangement.

The project delivered:

✅ Two new Grundfos vertical multistage pumps.

✅ Replacement of the ageing booster equipment.

✅ Installation within the existing plant room.

✅ Completed electrical and mechanical connections.

✅ Correctly configured pump sequencing.

✅ Verified pressure and vessel settings.

✅ Full operational testing and commissioning.

✅ A fully operational twin booster pump system.

The upgrade provides a modern replacement for the ageing equipment, helping support reliable water pressure and ongoing system performance.

Why Choose a Twin Booster Pump System?

Reliable Water Pressure for Residential & Commercial Buildings

Twin booster pump systems are commonly installed in properties where reliable water pressure is essential.

Rather than relying on a single pump, a twin booster arrangement uses two pumps to support the building’s water pressure requirements.

Depending on the system design and control configuration, the pumps can operate individually, alternate duty or work together during periods of increased demand.

Benefits of Twin Booster Pumps

Improved Reliability

A twin pump arrangement can provide additional resilience compared with a single pump installation, depending on system design and capacity.

Consistent Water Pressure

Booster pumps help maintain the required water pressure throughout a building, particularly where mains pressure alone is insufficient.

Flexible Operation

Twin systems can be configured to respond to varying water demand.

Reduced Pump Wear

Where duty rotation is configured, operating hours can be shared between pumps to help balance wear.

Maintenance Flexibility

Depending on the installation, one pump may remain available while the other undergoes servicing or maintenance.

Suitable for Multiple Applications

Twin booster pump systems are widely used in apartment buildings, hotels, offices, schools, healthcare facilities and larger residential properties.
