S 9425 and S 9430 Isocratic High - Pressure Pump The Schambeck SFD GmbH Pump HPLC System is intended for the ambitious analyst. The system configuration is highly variable and several upgrade options make this system suitable for the whole range of analytical applications. The HPLC Pump System is a very flexible and powerful HPLC solvent delivery system. Its modular setup makes the HPLC Pump System one of the most versatile pump systems on the market. The Pumps S 9425 and S 9430 are available as Isocratic High - Pressure Pump and Quaternary Low - Pressure Gradient Pump (see flyer S 9425 and S 9430 Gradient Low - Pressure Pump). The S 9425 and S 9430 Isocratic High - Pressure Pump is available with Micro, Analytical or Preparative pump head in Stainless Steel or PEEK. The S 9425 Isocratic High - Pressure Pump is delivered in a small housing. The S 9430 Isocratic High - Pressure Pump is delivered in a slightly larger housing (see technical specifications). The size of the pump housing are adapted to the two different auto samplers (60 vials or 120 vials). Stepper Motor The S 9425 and S 9430 Isocratic High - Pressure Pump are driven by high - power stepper motors. The stepper motor has a much better resolution in the low - flow range than a conventional DC motor. Fig.: S 9425 / S 9430 Isocratic Lubrication The S 9425 and S 9430 Isocratic High - Pressure Pump camshafts are constantly lubricated within a sealed chamber to guarantee long lifetime and low maintenance. Dual-Piston Pump head The S 9425 and S 9430 Isocratic High - Pressure Pumps use a dual-piston pump head for low pulsation. Together with electronic pressure compensation the pumps are suitable for all analytical tasks in HPLC and GPC. Optional: Piston Back Flushing The S 9425 and S 9430 Isocratic High - Pressure Pump heads incorporates an optional active piston back flushing system; this system is interchangeable with old Schambeck SFD GmbH pumps and does not require an additional motor
