Digital Dosing Pump

Digital dosing pumps in this catalog are the cards that say digital, stepper, or Evodose, including the LANGO EX sizes. The drive is a stepper or a brushless motor. This page adds no accuracy figure.

Signals stay on the card

Manual, pulse, 4–20 mA or RS485 appear only where that card says so. Read the card, then send the chemical and the duty on the quote.
