Description
The Kresco 1/2″ air-operated diaphragm pump is the transfer pump fitted to Kresco SR Series solvent recyclers and industrial parts washers. It moves solvents, water, slurries, waste oil and paint with nothing but shop air: no electric motor in the hazardous area, no seals to burn out running dry, and a PTFE diaphragm and stainless balls that stand up to the same solvents the recycler does. Use it as the dirty-solvent feed pump on an SR30 or SR60 (which load manually unless a pump kit is ordered), as a direct replacement for the pumps on an SR120, SR180 or SR240, or as a general-purpose solvent transfer pump between drums and tanks.
