Accurate, reliable dispensing for challenging liquids
The combination of FMI rotary piston pumps and Ismatec drives results in an exceptional range of pumps for very accurate and reliable dispensing, even when highly aggressive chemicals or viscous media need to be transferred. The pump heads are available with ceramic pistons and ceramic cylinder heads, components which resist highly aggressive chemicals.
Available from pump specialists MICHAEL SMITH ENGINEERS, FMI rotary piston pumps are designed for simple and reliable operation and require minimal maintenance. There are no valves to clog, leak or maintain and they have just one moving part – the piston. They offer drift-free operation of better than ±1% from set point, precision dispensing of -0.5% CV, deliver flows from microlitres up to 2.3 lit/min with positive displacement pumping and dispensing up to 6.9 barg. They are also self-priming and offer instant reversibility, so will pump in either direction.
FMI piston pumps can be supplied with two different types of Ismatec drives, the Reglo or MCP, both of which ensure very high repeatability. These drives provide users with benefits such as; 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 which can be automatically reversed at the end of a dispense to prevent any drips.
Control options include RS232 and analogue interfaces, speed control is proportional to a mA signal or through an RS232 connection and programmable models are also available. The option of either Reglo or MCP drives ensures optimum flexibility. For example, Reglo bench top drives enable a wide selection of different FMI ceramic piston pump heads to be fitted, capacities range from 0-045 to 180 ml/min and a digital version is also available which can be microprocessor controlled.
MCP drives are the ideal choice when dispensing and filling applications involve dusty, humid or corrosive environments or in clean rooms when IP65 protection is a requirement. These drives can be programmed on-site independent of a PC, they deliver higher capacities up to 2300 ml/min and they to 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, photo chemicals, inks, coating sweets and the addition of flavours.
