The modular design allows for many combinations of peristaltic pump drive units with pump heads, thereby creating a solution to meet virtually every need. Up to six 313 or 314 pump heads (also mixed) can be connected to a single drive. A maximum of 10 channels can be mounted on the five channel 314MC and 318MC supplementary heads (can also be mixed). Precision DC motor, maintenance free, high quality actuating drive with exact speed setting. Compatible with SPS and other systems with digital, analogue and serial communication options. User friendly operation, clearly legible display and framed membrane keypad for delicate operation. Stable, chemical resistant housing with smooth, hygienically clean surfaces and modern, highly functional design.

Model 323E/D with manual control and variable speed
The 323E drive is equipped with the 313D pump head. It can also be fitted with a 314D rotor if low pulsation is required. 313D2 or 314D2 pump heads are used for tubing with 2,4 mm wall thickness, in order to achieve higher operating pressures or for the transport of particularly viscous media.
Speed range: 15 to 400 min⁻¹ in increments of 5 min⁻¹
With 313D pump head for flow rates up to 2000 ml/min per channel
Speed ratio 27:1
Maximum six channels (optional fitting)
Can be switched from 100 to 120 V and 220 to 240 V

Model 323S/RL with manual control and variable speed
The 323S drive is equipped with the single-channel 501RL pump head. This is designed for large flow rates, long tubing life and increased accuracy. It can also be fitted with the 314 pump head if low pulsation is required. 313D2 or 314D2 pump heads are used for tubing with 2,4 mm wall thickness, in order to achieve higher operating pressures or for the transport of particularly viscous media. To transport smaller amounts with up to 10 channels, the 323U drives can be combined with 314MC (four roller) and 318MC (eight roller) micro cassette pump heads. A maximum of 10 channels is possble with the use of the 314MCX and 318MCX heads. Unauthorised access or unintentional changes can be prevented by activating the keyboard lock. After a drop in voltage, the pump restarts automatically. Two operational modes can be set (100 to 120 V/220 to 240 V).
Flow rates up to 2200 ml/min
Speed range: 1,5 to 220 min⁻¹ in increments of 1 min⁻¹
Equipped with 501RL pump head for large flow rates
Micro-processor-controlled drive
MemoDose function for exact batch dosage

Flow rates of up to 2000 ml/min per channel
Speed range: 3 to 400 rpm in increments of 1 min⁻¹
Equipped with 313D pump head, can be extended to six channels
Microprocessor-controlled drive
MemoDose function for exact batch dosage
