KNF STEPDOS® Liquid Pump

Processor Controlled Chemically-Resistant Diaphragm Metering Pumps

The STEPDOS® microprocessor controlled diaphragm metering pump is designed for use with neutral and aggressive liquids. The STEPDOS® pump produces continuous and steady flow even at low rpm which is achieved by means of a stepper motor. This ensures the suction part of the cycle is completed at maximum speed, but the output part of the cycle is controlled on a variable basis according to the selected speed. Constant adaptation of the motor speed results in a steady output over the entire cycle.

Two models are available:

• The S version for manual operation
• The RC version for either manual operation or external control (Windows® compatible software and cables included)

The compact size and the completely closed housing (IP 65) makes the STEPDOS® highly suitable for use in the laboratory and many industrial applications.

• Dispense Mode - variable volume metering
• Metering by volume from 50 µl to 115.2 l
• Metering by time from 0.34 s to 24 h
