Built On Legacy.

Over the past decade, the condensate pump industry has seen limited progress in genuine innovation. At BlueDiamond, a brand by Charles Austen Pumps Ltd, we’ve taken a different approach by building on proven patented technology and refining it through the latest advancements in design, manufacturing, and engineering.

Since the launch of our MicroBlue® almost ten years ago, our technical knowledge, design expertise, and production capabilities have grown substantially. Drawing on everything we’ve learned from our legacy range, we’ve combined this experience with the full strength of our modern manufacturing infrastructure to deliver our most advanced condensate pump series yet.

With more than 75 years of manufacturing heritage, Charles Austen Pumps has invested heavily in state-of-the-art EDM and CNC machinery, precision injection moulding, and dedicated toolmaking facilities. This investment has tripled our UK production capacity and laid the foundation for the V2 Series, the next generation of intelligent, efficient, and compact condensate removal pumps. Representing a new level of thinking in pump design, the V2 Series sets a fresh benchmark for performance, reliability, and intelligent engineering.

POWERED BY INNOVATION.

The V2 Series represents a major advancement in condensate pump technology. As the next evolution of our patented Rotary Diaphragm design, the V2 has been refined through advanced engineering and extensive testing in our Innovation Centre — the core of Charles Austen Pumps’ commitment to innovation, design excellence, performance, and British manufacturing.

Our engineers and research teams have spent years analysing performance data, reviewing customer feedback, and studying real-world installations to identify opportunities for improvement. Every insight gathered from installers, specifiers, and end users has shaped the development of the V2 Series. Each model has undergone rigorous testing in controlled environments that replicate extreme humidity, temperature variations, and contaminated condensate conditions to ensure durability, consistency, and long-term reliability.

At the centre of the V2 Series is the CS2 Chip intelligence, an advanced control platform that enables real-time communication between internal components (Sensor > Motor > Rotary Diaphragm). This allows each pump to automatically adapt its output to match the actual condensate volume being produced. For example, when the CondenSense™ reservoir is only partially full, the pump adjusts its performance to suit, conserving energy, minimising mechanical wear and reducing sound levels. With more than 250 active touchpoints, CondenSense™ technology provides dynamic speed control, soft-start operation, and continuous energy optimisation.

Earlier generations of condensate pumps in the market operated at a single fixed speed, removing water at a constant rate regardless of system demand. The V2 Series replaces this one-dimensional approach with a fully variable-speed system that self-calibrates to the connected HVAC/R unit. Once installed, it continuously learns from its environment, automatically adjusting speed to maintain optimal performance while remaining exceptionally quiet.

A key advantage of this new design is its ability to retain full torque at all speeds. Even when operating at reduced RPM, the pump maintains the same discharge pressure and drainage capability as it would at full speed. This ensures reliable condensate removal and consistent discharge distances, regardless of flow rate or operating conditions. The result is smooth, efficient performance with no compromise in pumping power, only reduced energy consumption and sound levels.

The V2 Series embodies the balance of intelligence, power, and precision. Designed through innovation, tested for reliability, and refined through real-world feedback, it delivers the performance professionals expect with the efficiency modern HVAC/R systems demand.

THE NEW BENCHMARK IN CONDENSATE MANAGEMENT.

The launch of the V2 Series marks a new era in condensate management technology. It represents the culmination of years of research, testing, and collaboration, brought to life through the expertise of the Innovation Centre and the manufacturing excellence of Charles Austen Pumps Ltd.

Summary of the new features:

Refined and enhanced version of our patented Rotary Diaphragm technology, delivered in a unified architecture across the full range
Brushless motor technology for improved reliability, precise flow control, and superior energy efficiency
CondenSense™ integration featuring CS2 Chip intelligence with over 250 adaptive touchpoints – Meaning lower operational costs through advanced energy performance and system optimisation
Self-learning functionality that recalls and refines performance based on previous operating conditions
Dynamic condensate monitoring to help prevent biofilm build-up and reduce maintenance requirements
Compact, unified design with integrated elastomeric feet for vibration isolation
Plug-and-play connectivity with pre-fitted cabling for simplified installation

For specifiers, installers, and end users, the V2 Series offers reliability, intelligence, and simplicity in one complete solution. It reflects the shared mission of BlueDiamond and Charles Austen Pumps to lead the industry through innovation, precision engineering and continuous development, something we started with the Rotary Diaphragm technology pumping principle.

The V2 Series will officially launch in November 2025, with the MiniBlue V2 and MaxiBlue V2 already available and the MegaBlue V2 set to follow in 2026. This next-generation platform will continue to roll out across the entire product range, with additional models and enhancements scheduled throughout 2026 and beyond.
