Since 1951 Sigmamotor Inc. has been an innovator and industry leader in medical pumping technologies. We developed the first peristaltic blood pump for open heart surgery, the first infusion pump, the first blood pump used in kidney dialysis and the first of the tumor perfusion units.
Today our focus has widened to include back pressure valves, pressure relief valves and calibration products for water disinfection and chemical dosing.
Sigmamotor back pressure valves, pressure relief valves and calibration cylinders are widely used as vital components in chemical feed systems for treatment and disinfection of drinking water as well as a myriad of other industrial, pharmaceutical, food & beverage and medical applications.
Our precision CNC machining facility is continually in demand for a wide variety of custom machined components.
