LP-3 Mini Diaphragm Liquid Pumps are a series of motor driven pumps for liquids. The unique design uses advanced technologies allowing these small liquid pumps to operate longer & harder than most other pumps. These mini liquid pumps work on the simple principal of the oscillating displacement pump. These liquid pumps can be mounted in any orientation. A wide range of DC motors, voltages & materials are available for specific needs. With proprietary brushless DC motors, pump life of 10,000 hours or higher is possible for certain models. These small diaphragm liquid pumps are most suitable for Analytical, Medical, Ink jet printers & Laboratory products. Dual head pumps can be used in different modes including in Series or in Parallel or as two independent pumps.
