The Viking range of universal seal gear pumps from Michael Smith Engineers has an electric heating option and is designed for pumping temperature-sensitive liquids. It is also suitable for applications where steam or hot oil is unavailable or the installation of long pipe runs is impractical.

The electric heating option is available on universal seal cast-iron gear pumps that have flow rates of up to 155m³/hr, for applications where process fluids need to be heated before start-up.

The device is made up of a number of heat cartridges — which are installed in the pump head, the bracket and the casing — and uses a temperature monitor and controller to keep the temperature within a set band. As the pump crescent is located in the centre of the pump casing, more of the heat is directly transferred to the liquid.

According to the company, the Viking pump is inexpensive to install as electrical heaters do not require long piping runs. In addition, electrical heating does not carry the environmental risks — and clean-up costs — of potential leakages from the pipe connections that hot oil systems have.

Further benefits

  • The Viking pump enables more precise heat control than steam or hot oil systems
  • The heater cartridges are shut off when the set band temperature is reached, cutting down on energy usage
