Thomas’  recent extension of its family of Jade products features two new diaphragm miniature brushless DC pumps. The new Jade models, 1410 and 1420 Series, are equipped with an electronically commutated brushless DC motor.  The high torque and speed rangeof the motor allows step-less variation of the performance of pneumatic diaphragm pumps (ranging from 2.5 to 11.0 lpm) so that the flow versus pressure/vacuum curve is held more linear than with a standard DC motor or other BLDC motors. In addition, the electronic commutation is virtually maintenance free making the new Jade models extremely durable with over 10,000 hours of lifeunder normal operating conditions. Available in 12V or 24V, the motors are equipped with integrated control electronics and are powered by a 4-wire cable with male connector.The lightweight, compact and closed-construction of these pumps make them ideal for medical, analytical, lab, fuel cell and general mechanical applications.
