Switching Delivery Pump

Switching Delivery Pump DP-11 made in Japan

solvent delivery pump without check valves


A single unit controlling high accuracy flow in multiple flow paths.
A new concept in multi-purpose pumps from FLOM. This smart pump can either dispense up to 5 separate channels, or continuously dispense just 1 channel, all in one device.

- Check valve-less design
- Can set flow to multiple paths
- High chemical resistance
- High accuracy flow volume
- Superior reliability
