MULTIPLEX PUMPS
The Multiplex series use a single motor and two lead-screws to drive multiple three-piece ceramic pump modules. The motor and lead-screw combination drive the pistons in a linear motion to create displacement. Each Pump Module has an air driven rotary actuator to turn the valve towards the intake or discharge port. Dispense volume is digitally selected through a RS232 computer signal or touch screen to produce a pulse free linear flow.

|---|---|---|---|
| 1. the module is shown at the beginning of the intake stroke. the flat on the valve opens the inlet port to the pump chamber and the outlet port is closed. | 2. suction is created during the intake stroke by the linear motion of the piston. | ||

| 3. the valve rotates 180° and the flat opens the outlet port to the pump chamber – the inlet port is closed. | 4. in the discharge stroke positive displacement is created by the linear motion of the piston. | ||
