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
