Product Details Supplier Info More products

Michael Smith Engineers is offering a range of pumps for 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 that resist highly aggressive chemicals.

There are no valves to clog, leak or maintain and the piston is the only moving part.

They offer drift-free operation of better than +/-1 per cent from set point, precision dispensing of -0.5 per cent CV, deliver flows from microlitres up to 2.3l/min with positive-displacement pumping and dispensing up to 6.9 bar.

They are also self-priming and offer instant reversibility, so will pump in either direction.

FMI piston pumps can be supplied with two types of Ismatec drives, the Reglo or MCP, both of which ensure high repeatability.

The drives provide users with benefits such as: choice of dispense functions by time or 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 Reglo or MCP drives ensures optimum flexibility.

Reglo bench top drives enable a 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 suitable for dispensing and filling applications that 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 2300ml/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 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.
