In industrial cleaning operations and in many process applications, liquids may have to be pumped at high temperatures.
The temperature of a pumped liquid can affect the properties of the liquid. Increased temperature may lower the viscosity of the liquid, reducing its lubricating properties. Increase in temperature can also increase the corrosive nature of the liquid. Water at 90°C is 64 times as corrosive as water at 20°C. These 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 sub-zero temperatures down to -10°C to -15°C.
