The Spectrex 300 series gas pumps use a high quality "tape-deck" type D.C. motor and provide extremely low power, high efficiency pumping for gases. They use a special, formed "viton" diaphragm and highly stable mylar valves. A specially designed mechanism provides variable stroke which can be set with extreme precision. As the motor can take from 3 to 15 volts D.C., the combination of correct stroke and voltage produce a highly efficient system.
