Centrifugal pump for aggressive fluids

The GVSO series of pumps has been developed from the company’s GVSN Series of vertical pumps.

While the GVSN pumps are typically used for pumping sulphuric acids, liquid sulphur, tar and molten salts, the GVSO pump can be used being used to address new applications in the solar power generation industry. These applications use molten salts with temperatures up to 560° C. The molten salt is used to help the transfer and storage of the heat.

Friatec says that is has already successfully tested its new GVSO pumps for several solar plants throughout Europe. The GVSO submersible pumps, which are suitable for aggressive fluids in high temperatures are made from high-grade stainless steels with a medium lubricated sleeve bearing concept.
