720R and 720RX continuous tubing pumpheads

720R pumpheads accommodate 4.8mm wall continuous tubing for joint-free flow from source to discharge. Available in five bore sizes: 9.6mm, 12.7mm, 15.9mm 19.0mm and 25.4mm, giving up to 8.8 GPM (2,000 l/hr) flow at up to 30 psi (2 bar) pressure.
720RX extension pumpheads offer identical performance, but at a maximum pressure of 15 psi (1 bar).
Tubing is available in five materials for almost any chemical requirement.



720RE and 720REX LoadSure tubing element pumpheads

720RE pumpheads accommodate 4.8mm-wall LoadSure tubing elements in two conformations: with PVDF Tri-clamp-style connectors for sanitary applications; and with industrial Cam-and-Groove connectors. Both are offered in four bore sizes: 12.7mm, 15.9mm, 19.0mm and 25.4mm, giving up to 8.8 GPM (2,000 l/hr) flow at up to 30 psi (2 bar) pressure.
720REX extension pumpheads offer identical performance, but at a maximum pressure of 15 psi (1 bar).
Elements are available in Pumpsil platinum-cured silicone, Bioprene and STA-PURE PCS for sanitary applications; and in Marprene, Pumpsil and Neoprene for industrial use.




These cased pump drives offer NEMA 4X (IP66) ingress protection for industrial and washdown environments:



720SN is a simple, plug-in-and-switch-on pump offering ultimate economy of ownership, with calibration and one-key manual control via a large-key membrane keypad. MemoDose provides single shot dosing
720UN is a keypad control or remote control pump with analogue speed inputs and status outputs. Software-configurable with password protection
720DuN is a sophisticated process pump with RS485 and full industrial connectivity, and process control through PC, PLC or other plant controller. Comprehensive calibration is available. Twin analogue inputs allow scaled flow adjustment. A 16-key numeric keypad with dial up flow rate or speed.
720BpN is the ultimate process pump with PROFIBUS connectivity



No point-to-point wiring and a simple 9-pin PROFIBUS D-connector provides:

Two way communication for control and status feedback
Pumps communicate at full PROFIBUS bus speed
No additional gateways or I/O converters required
Predictive maintenance
