GR pumps from Toyo include an agitator along with technical specifications adapted to the density of medium slurries, and the newest GR30 and GR30B also have a self cooling system. The pumps can operate when partially immersed but also at depths up to 30 m, in liquids with temperatures up to 60°C and pH values between 4 and 9.5.
The pumps from the GR range are equipped with a built in thermal protection, a class F motor, double mechanical seals working in an oil bath and an adjustable wear plate. Their pumping capacity and head, at duty point, are 90 m³/h at 30 m for the GR30 and 192 m³/h at 19 m for the GR30B.
Toyo GR pumps are suitable for duties in sedimentation tanks for mineral products, in quarries for handling stone cutting waters and in ceramic sawing for mud-silts treatment as well as in ready-mixed concrete, cement and chalk factories.
