Pulse-free dispensing pump for benchtops

A new pulse-free dispensing pump which offers good repeatability on a wide range of flows has been added to Michael Smith Engineers' range of pumps.

The Reglo Z is a compact digital drive unit designed for use with the Micropump range of magnetically coupled gear heads. Under test conditions these pumps achieved repetitive error (relative) results of better than 0.5% at 5ml, while at 100ml they achieved better than 0.1%.

The drive will accept the Micro-pump GA series, which are capable of flows from 0.85 to 420ml/min and differential pressures to 5.2 bar. They can also be combined with the Micropump GJ series providing flows from 32ml/min up to 3200ml/min at pressures to 1 bar.

A variety of operating modes ensures optimum flexibility: pumping by drive speed (rpm), flow rate (ml/min), dispensed volume (ml) and dispensing by time (0.1 second to 999 hours). It is also possible to pause the unit between dispenses and to set the number of cycles.

The drive is capable of speeds of 50 -5000rpm, while a five button membrane keyboard and LED display enable speed adjustment in steps of 1rpm. Calibrating functions are also included in both flow rate (ml/min) and dispense volumes (ml) modes.
