Hot and Cold Liquids


In industrial cleaning operations and in many process applications, liquids may have to be pumped at high temperatures.

The hot or cold temperature of a pumped liquid can affect the properties of the liquid. High temperatures may lower the viscosity of the liquid, reducing its lubricating properties. Hot liquids can also have an increased corrosive nature. Hot water at 90°C is 64 times as corrosive as water at 20°C. These high temperature effects can create maintenance issues for pumps with dynamic seals.

Its seal-less design enables the Hydra-Cell pump to avoid these problems because highly corrosive and abrasive liquids are always isolated from the fully lubricated drive end of the pump. For conditions of exceptional heat, Hydra-Cell compatible oil coolers are available, to maintain the pump's hydraulic liquid at optimum viscosity and allow the pump to handle difficult liquids at temperatures as high as 120°C. The Hydra-Cell design lends itself equally well to pumping at cold sub-zero temperatures down to -10°C to -15°C.

Whether hot or cold, your fluid can be handled reliably by Hydra-Cell.

The Hydra-Cell Advantage

  • Elimination of seal maintenance due to aggressive hot liquids
  • No dynamic seals to be damaged by non-lubricating hot liquids
  • No high speed rotating parts with dynamic seals in contact with process liquid
  • Simple construction - 
    • Simple service can be carried out without removing pump from installation
    • Larger models have been specially designed so that no heavy lifting equipment is needed to carry out liquid end service
    • No special tools or techniques are needed to carry out maintenance
    • No tight tolerances to maintain or set
