New 620 EC / 625 EC: doubled free flow!

These pumps are a modification of our well-proven SP 600 EC. Thanks to a revolutionary diaphragm / valve design we were able to double the free flow performance without increasing the rpm of the motor! The high flow in combination with the small dimensions predestines these pumps for gas analysis devices. The pumps are equipped with long life motors and double ball bearings. They are also available with brushless motors.
