What submersible pumps do: Submersible Turbine Pumps (STPs) transfer fuel from aboveground or underground storage tanks to dispensers by pushing the fuel under pressure through the piping system to the dispensers.
What’s new with STPs: Today’s submersible pumps are constructed with stainless steel and other materials that resist corrosion. These modifications make the pumps compatible with a wide range of current fuels and they increase the likelihood the pumps will be compatible with future fuels. Due to the higher quality construction materials used, the price of submersible pumps has increased. Choosing a pump that will provide return on investment through long-term, reliable operation is important. Also, the 2 Horsepower pump has grown more popular.
