More About this Item

With the trend to conserve valuable liquids and the need for high-precision movement of fluid, these pumps are becoming a necessity. Internal technology, similar to that of gear pumps, keeps pulsations to a minimum ensuring smooth, consistent flow necessary in applications such as analytical instruments, fuel cell and micro-reaction technology, biotechnology, and other critical application processes.

Micro-annular gear pumps are rotary pumps that are constructed with an externally toothed internal rotor as well as with an annular tooth external rotor, which bear slightly eccentric to each other. During rotation of the rotors around their offset axis, the pumping chambers simultaneously increase on the induction side and decrease on the delivery side of the pump. A homogeneous flow rate is generated between the kidney-shaped inlet and outlet. The small footprint allows for easy integration into a layout to facilitate the research.

Low-Pressure Models are supplied with DC motors with graphite brushes and are fitted with encoders.

High-Performance Models are provided with actuator equipped with an electronic commutated, brushless DC motor and integrated control unit. Control can be an RS-232 interface using Windows® Motion Manager software (included) or via an analog input signal, supply voltage 12 to 24 VDC.
