Applications
GPA pump has an additional axial impeller,
It is used for pumping the liquid foam resulting from high-speed machining operations,
Pumping metal chips together with the fluid by mixing,
Filtration systems,
Hot liquid applications,
GPA Pumps are used for pumping of cutting / cooling fluids in circulation systems.
GPF pumps are used for pumping of liquid from vacuum zone on filtration systems. The pump works at vacuum zone, therefore it has an O-ring at the pump inlet. It also has an additional axial front impeller
