Diaphragm pumps with BLDC motor

The Jade family of pneumatic diaphragm pumps now feature an electronically commutated BLDC motor. The high torque and speed range of the motor allows stepless variation of pump performance — the flow versus pressure/vacuum curve is more linear than with a standard dc motor or other BLDC motors in this size range.

The motors are equipped with integrated control electronics and are powered by a four-wire cable with male connector. Reference input and motor speed are changed to deliver a wide pneumatic performance range — 2.5 to 11.0 lpm, depending on model. With the increase in pressure, speed is adjusted automatically. The electronic commutation is virtually wear-free and reaches operating life of at least 10,000 hr under standard conditions.
