Air-driven liner pump
The Flex-I-Liner pump is designed for use in remote areas where electricity is unavailable or when a spark may ignite the substance being pumped. Providing gentle pumping action, it operates wet or dry and can be supplied with rotary vane air motors. Designed to eliminate shaft seals, stuffing boxes and other common sources of leakage, this pump can be supplied with reversible operation to allow for changing flow direction. Its motors develop up to 2000 rpm on 90 psi and control of the air motor drive allows for varying flow rates within +/-5 percent. No special tools are needed for maintenance.
