Dispensing and filling pumps offer reliability and repeatability
Michael Smith Engineers is introducing the FMI range of ceramic piston pumps that offer OEMs and machine builders a combination of reliability, repeatability and flexibility for dispensing and filling applications.
FMI pumps are designed for simple and reliable operation and require minimal maintenance, thanks to features such as no valves to clog, leak or service, and just one moving part - the piston. They offer drift-free operation of better than 1 per cent from set point, precision dispensing of -0.5 per cent CV, flows from microlitres up to 2.3 litres/minute with positive displacement pumping and dispensing up to 6.9barg. The pumps are also self-priming and offer instant reversibility for pumping in either direction.
Michael Smith Engineers can supply the FMI piston pumps with two different types of drives, both of which ensure very high repeatability. These drives provide users with benefits such as: a choice of dispense functions by time or by volume; output set by speed or flow rate; interval dispensing with a pause or with a preset number of dispensing cycles; and a piston stroke that can be reversed automatically at the end of a dispense to prevent drips.
Remote control or programmable
Control options include RS232 and analogue interfaces; speed control is proportional to a mA signal or via an RS232 connection, and programmable models are also available.
The option of either Reglo or MCP drives ensures optimum flexibility. For example, Reglo benchtop drives enable a wide selection of different FMI ceramic piston pump heads to be fitted. Capacities range from 0.045 to 180ml/min and a digital version is available that can be microprocessor controlled.
MCP drives are suitable for dispensing and filling applications involving dusty, humid or corrosive environments or in clean rooms when IP65 protection is required. These drives can be programmed on-site independent of a PC, they deliver higher capacities up to 2300ml/min and they can be fitted with a wide selection of different FMI piston pump heads.
Typical applications for the FMI piston pump with either the Reglo or MCP drive include accurate dispensing of sensitive fluids in medical, biotech and pharmaceutical applications, transferring corrosive fluids in industrial and electronics manufacturing, metering and mixing paints, metering petroleum additives, metering photo chemicals or inks, coating sweets, and the addition of flavourings.
