Profile: Pump Aid Corporation is in the field of supplying centrifugal, metering, viscous and pumping systems. Our nonmetallic centrifugal pumps are single stage pumps with involute, self venting type casing, dynamically and hydraulically balanced impeller with aerodynamic profile vanes. Our metering pumps are fine control elements, which can be electrically controlled by remote or automatic process control instruments and have higher linearity and higher control accuracy than conventional control valves. Our monoscrew pumps are rotating positive displacement pumps, which are transferred through a displacement unit in the form of pressurized energy.
