Micro annular gear pumps provide precise, pulseless flow

June 19, 2006

Micropump''s micro annular gear pumps offer precise flow rate control for outstanding performance in a variety of applications. Offered in a Low Pressure (Series ML) or High Performance (Series MH) configuration, these compact, versatile pumps help conserve your valuable liquids and increase the overall efficiency of your system. For maximum dosage accuracy, Series ML and MH pumps feature high-precision rotors that provide tight flow rate control, even at differential pressures as high as 80 bar (1,160 psi). These rotors allow the pumps to dispense volumes as small as 0.25 microliters and handle flow rates from 0.15 to 300 ml/min, with accuracies within ± 1 percent. In addition, the pumps use gear tooth forming technology that keeps pulsations to a minimum to provide the smooth, constant flow necessary in applications such as analytical lab instruments, medical diagnostics, chemical processing, fuel cells, biotechnology, micro reaction technology, and other critical application processes. Measuring as small as 13 mm (0.51 inches) in diameter by 68 mm (2.67 inches) in length, Series ML and MH micro annular pumps are easily integrated into OEM equipment with small footprint, low weight, and short tubing length requirements.
