Operating Manual
11.1.2 Binary Pump
The pump performance is specified as follows:
Type Specification*
Operating principle Serial dual-piston pump
Compressibility compensation Fully automated, independent of the composition of the mobile phase
Flow range (settable) VC-pump:
0.001 – 10 mL/min in 1 µL/min
increments
VF-pump:
0.001 – 8 mL/min in 1 µL/min
increments
Flow accuracy ± 0.1%
Flow precision < 0.05% RSD or < 0.01 min SD, whichever is greater
Pressure range VC-pump:
2-70 MPa (20-700 bar, 290 –
10100 psi)
With a flow rate of > 5 mL/min,
the maximum pressure decreases
linearly down to 30 MPa (300 bar,
4350 psi).
VF-pump:
2 – 103 MPa (20 – 1034 bar, 290 –
15000 psi)
With a flow rate of > 5 mL/min,
the pressure range decreases
linearly down to 80 MPa (800 bar,
11600 psi).
Pulsation < 1.0% or < 0.2 MPa, whichever is greater
Gradient formation High-pressure gradient proportioning
Proportioning accuracy ± 0.2% (of full-scale)
Proportioning precision < 0.15% SD
Number of solvents 2 out of 6
Maximum stroke volume 80 µL
Mixer volume VC-pump:
Standard configuration: 400 µL
mixing system, consisting of a
capillary mixer (volume: 50 µL)
and a static mixer (volume:
350 µL)
Other mixing systems are
available as an option.
VF-pump:
Standard configuration: 200 µL
mixing system, consisting of a
capillary mixer (volume: 50 µL)
and a static mixer (volume:
150 µL)
Other mixing systems are
available as an option.

system gradient delay volume) 400 µL (in standard pump
configuration)
(35 µL to 1550 µL with optionally
available mixing systems)
200 µL (in standard pump
configuration)
(35 µL to 1550 µL with optionally
available mixing systems)
Solvent degassing Built-in, number of channels: 2 out of 6
