These pumps are suitable for use in both residential and commercial applications and come with several key features to ensure efficient and effective operation.

The X87-711 and X87-721 are 230V condensate pumps, making them a versatile choice for a wide range of heating systems. They are designed to handle condensate water from high-efficiency condensing boilers and water heaters, making them an essential component for modern heating systems.

These pumps are equipped with a powerful, permanently lubricated, magnetically driven, stainless steel impeller. The impeller is designed to handle high volumes of condensate water, ensuring that the pump can keep up with the demands of even the most demanding heating systems. The impeller is also designed to be self-priming, meaning that it can operate even when the water level in the condensate tank is low.

The X87-711 and X87-721 are also equipped with a non-return valve, which helps to prevent backflow of condensate water into the heating system. This valve ensures that the pump is always pushing water in the correct direction, helping to maintain the efficiency of the heating system and prolong the life of the pump.

These pumps feature a robust, corrosion-resistant cast iron housing, which helps to protect the internal components from the corrosive effects of condensate water. The housing is also equipped with a drain plug, making it easy to drain the pump for maintenance or winterization.

The X87-711 and X87-721 are designed to be quiet in operation, with a sound level of just 45 dBA. This makes them an ideal choice for use in residential applications, where noise levels are a concern.

Overall, the Diamond X87-711 and X87-721 Maxiblue Condensate Pumps are high-performance, reliable, and efficient solutions for handling hot water condensate in heating systems. Their powerful impeller, non-return valve, corrosion-resistant housing, and quiet operation make them an essential component for modern heating systems.
