The FDD Pulseless Nanoliter Pump is an ultra low flow dispensing pump that is capable of offering dispensing of less than one microliter at market leading precision and accuracy. Only three moving parts enables highly stable operation as well as a long-lasting pump life minimising maintenance costs.
An anti-backlash mechanism has been fitted which helps to provide consistent measures including when switching pump directions. The motor turns counterclockwise to dispense and clockwise to aspirate with a speed of up to 2000 steps a second. A remarkably low flow rate of 0.105µL/sec is provided at 1 rpm with a maximum flow of 62.8µL/sec at 600 rpm.
The dispensing volume ranges from 0 to 150µL with accuracy and precision at top range volume being as little as ±0.1%. It has a typical accuracy of < ±2% at 1µL. A pulseless smooth flow offers up to 98% stability thanks to a linear drive and a fine pitch lead screw.
Wetted materials within the pump include ceramic (Alumina or Zirconia) as well as PVDF, UHMW-PE and FKM. These offer a substantial improvement in lifetime and chemical inertness within the market. The maximum operating pressure is 100 psig (6.89 bar) and the temperature range is between -20°C and 50°C.

A. All other Fluid Metering products are rotating and reciprocating pumps. The Fluid Metering Direct Drive is a hybrid in-line pump, with syringe pump capabilities. The FDD can do discrete dispenses ranging from less than 1uL, all the way up to 150uL.
A. 32nL per full step.
A. Any application requiring a high level of accuracy and precision at very small volumes.
A. Yes, with up to 98% flow stability.
A. Yes, down to 1uL.
A. 1/16”OD x 1/32” ID hard tubing, 22-26 gauge dispense tip (varies per application).
A. The pump-head can be configured with PEEK, PVDF, or PTFE, and a variety of seal materials, to best fit your needs. We can also test your reagents for chemical compatibility.
A. No maintenance is required. However, after using any fluid that might crystalize or precipitate, it is best to run a flush cycle if the pump will be idle.
A. We recommend using a priming pump (see Fluid Metering STF pumps). Alternatively, the FDD can self-prime with the use of dual valves (not included). A gravity-fed system can also be used.
A. Yes, please contact one of our Sales Associates for more information.
