Series 7049 Miniature Diaphragm Liquid Pump
Models 7039 & 7049 liquid diaphragm pumps are an excellent choice where flow control, chemical resistance, plastic wetted components, DC power operation and quiet, reliable performance are required. They are typically used on medical equipment, laboratory automated chemistry applications, environmental sampling equipment and a range of industrial applications such as pick-and-place operations, ink jet printer systems and food packaging equipment.
Model 7039 & 7049 pumps incorporate a 24 V stepper motor and have a nominal delivery of 32 ml/min (0.32 ml/stroke) at 100 RPM. The motor shaft incorporates an eccentric that is attached to the pump diaphragm. Two opposing floating discs with seats respond to the diaphragm motion resulting in pumping action.
A driver circuit is offered as an option for driving the stepper motor. A photomicrosensor is also available for feedback based on the position of the diaphragm.
The pump is produced by Namiki Corporation, a world leader in DC motor production and technology.
