Chemical transfer pumps are designed to circulate mildly corrosive acids, alkalis, plating and sterile solutions and solvents for in cosmetics, pharmaceutical and food industries. Raptor Supplies offers a wide range of low- to medium-flow chemical transfer pumps from brands like Finish Thompson, Grainger and Little Giant Pumps. These pumps feature magnets on the impeller and a motor shaft for transferring full torque of the motor to the pump. With the motor shafts not in direct contact with their wet end, these magnetic-drive pumps are not only able to effectively reduce the occurrence of pump leakage but also the maintenance cost of a mechanical seal. To further reduce human effort, self-priming option is available on selected pumps. These pumps do not require manual filling of the suction pipe with liquid to remove air. Choose from a wide range of magnetic-drive pumps, available in Buna-N, EPDM, FKM, fluoroelastomer and Viton gasket materials, on Raptor Supplies.
