Submersible Pumps for High Temperature Liquids

Tsurumi manufactures submersible pumps to handle liquids up to 80°C. Many are already in service at sites that need to discharge high temperature liquids, including industrial wastewater from power plants and steel mills, and hot spring discharge from mines in volcanic zones.
Tsurumi's standard specification pumps can move liquids of up to 40°C, but Rank 60 and 80 pumps are available as options for liquids of 60° and 80°C, respectively. Insulation class, rubber materials, lubrication and bearing grease are upgraded for each temperature rank.
Backed by years of experience and know-how, Tsurumi develops hot liquid pumps to withstand harsh working conditions. Tsurumi also has a wide lineup of pumps for moving seawater and corrosive liquids. For more information, contact an authorized Tsurumi pump dealer.
