Model N838 twin-head diaphragm pumps come with ac, dc, and brushless-dc motors.
They give two flow ranges, 42 and 64 liters/min, with an end vacuum of 27-in. Hg (68 Torr). Target uses are continuous-duty surgical suction devices and aspirators. The BLDC models feature low EMI and RFI levels, wide-range remote speed control, and logic on/off capability. A patented multiport valve design offers increased flow, gas tightness, and withstands moisture. Other applications are liposuction, analyzers, and sampling systems.
