Description
The unit is in full working condition and is ready for immediate use
The 620DU is a process peristaltic pump (i.e. hose pump) designed for metering, dosing, and transfer of fluids.
Because it is a peristaltic design, the fluid is contained entirely within the tubing, avoiding contact with internal moving parts (other than the tubing).

It is suitable for remote control, automation, and integration into control systems (SCADA, factory logic, etc.).
Wide control range & precision: The large turndown (2,650:1) gives flexibility to handle both very low and high flow rates with fine control.
Remote / automation capabilities: Because it supports analog and digital interfaces, it’s well-suited for integrated systems.
Pump protection & security: PIN locking helps avoid unintentional changes in process-critical applications.
Low maintenance on non‑wetted parts: Since only the tubing contacts fluid, mechanical wear is mostly on the tubing, making part replacement simpler.
Safe to run dry: Peristaltic pumps typically tolerate running dry without damage (unlike many positive displacement pumps).
Reversible / ability to back‑flush: This is helpful when attempting to clear lines or avoid clogging.
Limitations / Considerations
Tubing wear / life: The hose or tubing is the consumable component. Chemical compatibility, pressure, and mechanical stress affect how often tubing needs replacement.
Upper pressure / flow limit: While it handles decent pressure (~2 bar standard, possibly up to 4 bar variant), it’s not suited for very high-pressure pumping tasks.
Enclosure limitations (non-“N” model): The standard 620DU is not fully sealed, so it may not be ideal for wet or harsh environments unless you use the “N” variant.
Cost / complexity: More features, interfaces, and protection can make the system more complex (and costlier) to configure, install, and maintain.
