The 620N from Watson-Marlow is engineered with R pumpheads that can flow at 30 psi (2 bar) up to 4.2gpm at optimal pressure. It is equipped with a sturdy tool-unlockable guard and MemoDose to ensure quality and convenient single-shot dosing. D-Connectors allow for easy user control via digital, analogue or remote means depending on the user.

It runs on NEMA 4x (IP66) ingress protection to protect dust particles and water pressure from damaging the pump drives, making it possible for the machine to withstand extreme environments. Its speed control range of 0.1 to 365 rpm (in 0.1 rpm increments) has a precision rate of 2650:1 and runs on a dual voltage of either 115V/230V.
