Drum and barrel pumps include siphon pump, rotary pump, hand pump and piston pump models. All can be helpful in handling lightweight oils and soap solutions typically used in automotive and cleaning applications. A barrel pump can add speed, convenience and control to dispensing low-viscosity fluids, while an air drum pump uses compressed air for helping dispense heavier-weight liquids. Barrel accessories, like a barrel liner, barrel adapter or barrel seal, help minimize slippery spills from leakage and keep workers safe around drum and barrel pump stations.
