This article simplifies the four main cooling methods of Hydroblue submersible wastewater pumps. Helping you quickly select a cooling solution that fits your needs and get reliable pumping performance.
It utilizes the latest technology, suitable for both dry and wet installations, where the motor is not sufficiently submerged. The closed loop keeps coolant from being contaminated by impurities in the pumped media, and the pump can run at lower speeds.
It’s a simple, low-cost solution that uses the pumped liquid to cool the pump. It works well for installations where the motor is mainly submerged during operation, especially for axial flow pumps and fully submerged centrifugal pumps.
Closed-loop media cooling works by circulating a portion of the pumped liquid through a cooling jacket around the stator housing. Air is automatically removed through a ventilation pipe during the first startup, so it does not rely on the liquid level. It is suitable for dry installations and some wet installations where the motor is not fully submerged.
It’s for applications where liquid temperatures exceed 40°C for a long time. An external clean water supply connects to the cooling jacket around the stator housing (clean water is needed when the pump runs) to maintain the motor’s full power.
Hydroblue stands out in the submersible wastewater pump field with obvious advantages. We not only offer flexible pump configurations to meet diverse needs but also provide reliable cooling systems (closed-loop, direct, external) that adapt to different working conditions—ensuring optimal performance, lower operating costs, and simpler maintenance. Whether you need a solution for dry or wet installations, submerged motors, or high-temperature liquids, Hydroblue has you covered.
