KPM20B-4B

Our pump KPM20B-4B is a micro air pump, which is used for the motion of gases. They are characterized by their high reliability and performance with small size of approx. 55,5 x 36,0 x 15,4 mm. They operate at DC 3.0V voltage with max. current 430 mA and have a free flow of more than 1300 ml/min at 0-400 mmHg pressure while the noise is maximum 70 dB (A) and the lifetime is 30,000 cycles. The pumps are used in medical industry, for example in blood pressure measurements patient monitors, in therapeutic devices with air pressure waves or in massage therapy. You can find further information on the corresponding technical data sheet and/or CAD-file.
