D-25VT 2-Roller Peristaltic Dispensing Pump with Cyclic Timer

The D-25VT is the cyclic timer variant of the D-25V series. Flow performance and digital control are identical; the addition is independent programming of dispense and stop intervals. Suited to repeated dosing applications where continuous operator attendance is not practical.

Control and Operation

• Flow rate: 2 to 750 ml/min
• Speed control: Digital, 0 to 99 % in 1 % increments
• Repeatability: 100 %
• Timer: Cyclic — dispense time and stop time programmed independently
• Flow reversal switch: Included
• Maximum flow pushbutton: Included
• Footswitch connection: Included
• Remote control: Included (0–10V signal version also available)
• Pilot light and main switch: Included

Pump Head and Tubing

This model is fitted with a 2-roller polycarbonate rotor head. The D-25VT range accepts alternative heads depending on application:

• Head L2000-3r: Cartridge with integrated removable tubing — released by a single retaining clip. Compatible with 8 mm tubing only.
• Head L1500-2r: For 2.4 mm wall tubing. Recommended for viscous products.
• Head 5000: Self-adjusting — compensates for tube wall wear during extended runs.
• Head CF-3r: Quick-load design for fast tube changes. Allows simultaneous use of two heads; tube diameter is limited to 4.8 mm in that configuration.

An assortment of tubing and connectors is included.
