Trading and engineering company focusing on process pumps
Copenhagen Pump, Green Pump and established Medico companies, developed a pump that fulfills a wide range of Medico-validated characteristics. The pump is used for pumping hot sterile water. The challenge of this pumping task is temperature-induced cavitation in combination with a high tightness requirement and a wide range of material, material processing and documentation requirements.
Cavitation is the formation of vapor bubbles as a result of the ambient pressure of the liquid falling below the vapor pressure of the liquid. When this balance is reached, a phase change from liquid to vapor occurs. In a pump, this phenomenon is called cavitation.
The phase shift and cavitation can occur for many reasons, but is typically due to the operation of the system. The typical pump solution is based on a close coupled turbine pump that can handle up to 20% steam. Despite this special ability, it is essential to ensure cavitation-free operation. Cavitation-free operation is ensured by calculating/determining the plant's NPSH (A) value, good plant understanding and good plant operation.
