S 1130 — One Pump. Three Configurations.
The S 1130 HPLC pump system is an exceptionally flexible and powerful solvent delivery platform. Its modular architecture makes it one of the most versatile pumps on the market. Choose from three configurations: isocratic delivery, quaternary low-pressure gradient (S 1130G), or binary high-pressure gradient (S 1132) — and combine configurations into multi-flow systems. Optional integrated vacuum degasser and active piston back-flushing available.

Stepper Motor
High-performance stepper motor with intelligent motor management — extremely high resolution across the dynamic flow range.
Dual-Piston Pump Head
Electronic pressure compensation with precision dual-piston delivery: minimal pulsation for all HPLC and GPC applications.
Robustness
Sealed, permanently lubricated cam shaft — long service life, minimal maintenance.
Mixer Synchronisation
For precise low-pressure gradient elution, valve control is synchronised exclusively to the piston intake phase.
Active Piston Back-Flush (Option)
Pre-configured pump heads support automatic active piston back-flushing without additional drive. Retrofittable to older systems.
Vacuum Degasser Module
Integrated 4-channel vacuum degasser with Teflon AF® membranes: < 20% dissolved gases remaining in water at 1.000 ml/min.
