Piston diaphragm pumps are positive displacement pumps designed to economically transfer small volumes of fluid at low discharge pressures. The lightweight, compact pumps are self-priming, corrosion resistant and can handle viscous fluids. These features make the pumps ideal for high volume copy machines, scientific and laboratory instruments and other chemical dispensing applications.
Flow Rate: Range to 250 microliters per stroke.
Max. Discharge Pressure: Range to 2.6 psi (6′).
Self-Priming: To 3 feet.
Max. Fluid Viscosity: To 300 centistokes.
Max. Fluid Temperature: To 200°F (93°C).
Typical Duty Cycle: 1 cycle/second (1/2 sec. on – 1/2 sec. off). Higher frequency operation achievable with external driver.
Metering Accuracy: ±2% stroke-to-stroke (for a stationary setup).
I.D. Tubing Size: 3/16″.
Approximate Weight: .265 lb.
