Available from Michael Smith Engineers Ltd, the UK’s leading pump specialist, FMI metering pumps are positive displacement ceramic piston pumps. By combining synchronous rotation and reciprocal motion of the ceramic piston in a precisely mated ceramic cylinder liner allows the pumps to operate without any valves. One complete piston revolution is required for each suction/discharge cycle and the piston always bottoms to ensure maximum bubble and fluid clearance from the cylinder liner.
The main benefits of the FMI valveless piston pump design are:-
• No valves to clog or leak
• Accurate, repeatable positive displacement output
• Self priming
• Simple design
• Output capacity independent of viscosity
