Piston Diaphragm Pumps

Product Overview

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.

Operation:
Standard models are constructed with 12 or 24 volt DC solenoids. A switch is required to supply pulsed voltage to the pump. The energized solenoid pulls the piston and diaphragm up, drawing fluid into the pump. A spring forces the piston back to its original position when the solenoid is de-energized, forcing fluid out of the pump, and the cycle is repeated. Valves are utilized to prevent back-flow into the pump and to maintain prime.

Specifications:
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)
