Blue Diamond

Charles Austen Pumps Ltd design and manufacture a comprehensive range of condensate pumps for all air conditioning needs. Established for over 50 years Charles Austen Pumps are leading manufacturers of condensate removal systems. In addition to off the shelf units, a range of components and materials are available to adapt standard products to meet a variety of applications. Condensate removal pumps are usually an installers nightmare. They have a reputation for being awkward to install and unreliable which often dictates the buyer choose the cheapest item and regard it as a throw away. Many competitors boast about how reliable their products are, but this is very rarely the case. The BlueDiamond range from Charles Austen Pumps offers a new approach to efficiently, quietly, and reliably remove large quantities of condensate. BlueDiamond condensate pumps are based on a revolutionary patented rotary diaphragm pumping principle. Proven in service for over 15 years on applications including vending and sampling. The principle overcomes problems such as contaminated valves, stuck pistons, split tubes and noisy gearboxes which is how BlueDiamond pumps achieve their extremely high rate of reliability and complete lack of noise, making them the most popular choice of pumps across the world. All BlueDiamond pumps are guaranteed for three years.
