Hydra-Cell^® pumps reliably handle hot liquids up to 250°F / 120^°C*.

Pumping hot fluids can be a difficult application. Concerns include avoiding cavitation and maintaining proper lubricity in the hot water pump's hydraulic end. Chemical attack on dynamic seals and packing is accelerated as the liquid temperature increases. Increasing maintenance. Pumps with dynamic seals need special and expensive seal and packing materials; seal flushing may also be required.

Many liquids are thinner when hot, and as temperature rises their ability to lubricate the seals reduces, rendering them less effective and increasing risk of internal leakage. Some liquids can become more corrosive at higher temperatures. For example, water becomes more corrosive at 194°F / 90°C than at 68°F / 20°C.

The seal-less design of Wanner™ Hydra-Cell® Pro pumps enables them to handle virtually any liquid over a wide range of temperatures and pressures. When handling hot liquids, a key feature of the Hydra-Cell Pro design is that the pumped liquid is isolated from the drive mechanism and 100% contained within the fluid end. The pump can handle heat simultaneously with other demands of the system, such as high operating pressure, harsh liquid content and poor lubricity.

In the Hydra-Cell Pro design, with no seals to wear, heat is not a factor, so the pump continues to be reliable, even up to 250°F / 120°C, with the viscosity of the lubricant in the drive end of the pump held within prescribed limits.

*NOTE - For some installations, an oil cooler maybe needed for some duties over 90°C/ 194°F. Consult factory for correct component selection for temperatures from 160°F (71°C) to 250°F (121° C).
