Description
The DP-11 Switching Delivery Pump from FLOM provides an innovative solution for solvent delivery and collection. The robust, durable design has an integrated linear drive for improved flow stability and reduced maintenance needs. With its compact size and compatibility with a variety of chemicals, this pump is ideal for a wide range of applications. Ceramic, PCTFE PTFE and FFKM make up the wetted materials while the advanced FLOM valves allow for the dispersal of solvent from a single line over five different lines.
Features
Check valve-less design
- NO CHECK VALVES! This results in fewer maintenance problems and avoids the typical problems you get when pumping highly viscous liquids.
Can set flow to multiple paths
- This smart pump can either dispense up to 5 separate channels, or continuously dispense just 1 channel, all in one device.
High chemical resistance
- Ceramic and PCTFE chosen for the wetted materials provide high resistance for a wide range of liquids including strong acids
High accuracy flow volume
- Accuracy : ±1.0 % or ± 0.01 mL Repeatability : ± 0.1 % RSD or 0.00 1mL SD (Measuring Mode)
- The DP-11 offers high accuracy flow in both Continuous Flow and Measuring modes.
Superior reliability
- Rugged design uses FLOM’s proven linear drive and a smaller mechanical load reduces maintenance frequency.
Improved Communication
- Remote control thru RS232C communication and RS485 between FLOM devices
