300 series drives and pumpheads • 313D three-roller high flow pumphead The modular design means that many more combinations of drives and pumpheads than those shown on the previous page are possible. Five drives couple to four pumphead types, options to meet every need: Up to six 313 or 314 pumpheads can be fitted to one drive, and up to two 314MC or 318MC (which can also be mixed) can be fitted to a single drive to provide ten channels of flow. • 313D2 three-roller high flow pumphead for 3/32” (2.4mm) wall tubing • 313X three-roller extension pumphead - add up to five extra channels • 314D four-roller...

323 drives can be fitted with 314D four-roller pumpheads when lower pulsing is required (flow rates will be lower than with the 313 three-roller pumphead), and up to four 314X extension pumpheads can be fitted, depending on the size of the tubing fitted and the pressure in the system. Note that 314D pumpheads can be run up to a maximum of 300rpm. 323E, 323S, 323U, 323Du and 323Dz drives may also be fitted 313D2 or 314D2 pumpheads which accept 2.4mm thick wall tubing for higher pressure operation or pumping more viscous fluids. 313D2 or 314D2 pumpheads make higher torque demands, and extension...
