Hot Liquids

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

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; water becomes more corrosive at 90°C than at 20°C.

Their seal-less design enables Wanner’s Hydra-Cell pumps to handle virtually any liquid over a wide range of temperatures and pressures. When handling hot liquids, a key feature of the Hydra-Cell design is that the pumped liquid is isolated from the drive mechanism and 100% contained within the fluid end, and 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 design, with no seals to wear, heat is not a factor, so the pump continues to be reliable, even up to 120°C and the viscosity of the lubricant in the drive end of the pump should be held within prescribed limits.

(*NOTE - For some installations, an oil cooler maybe needed for some duties over 90°C).
