Product catalog summary
Overview
The Schambeck SFD GmbH S 9425 and S 9430 Isocratic High-Pressure Pumps are designed for versatile analytical applications. These pumps are part of a modular HPLC solvent delivery system, offering flexibility and upgrade options.

Specifications
The pumps are available in two configurations: Isocratic High-Pressure and Quaternary Low-Pressure Gradient. They come with Micro, Analytical, or Preparative pump heads made from Stainless Steel or PEEK. The S 9425 model features a smaller housing, while the S 9430 has a larger housing, both adaptable to auto samplers with 60 or 120 vials.

Technical Features
  • Stepper Motor: High-power stepper motors provide better resolution in low-flow ranges compared to conventional DC motors.
  • Lubrication: Camshafts are lubricated within a sealed chamber for longevity and low maintenance.
  • Dual-Piston Pump Head: Ensures low pulsation and, with electronic pressure compensation, is suitable for HPLC and GPC tasks.
  • Optional Piston Back Flushing: An interchangeable system with older models, requiring no additional motor.

Technical Specifications
  • Wetted Materials: Stainless Steel, PEEK, Teflon AF®, PVDF, Ceramics, Sapphire, Ruby.
  • Flow Rate: Micro: 0.001 - 2.000 ml/min, Analytical: 0.001 - 10.000 ml/min, Preparative: 0.100 - 40.000 ml/min.
  • Flow Accuracy: ± 1.0% at 1.000 ml/min.
  • Flow Precision: ± 0.1% RSD at 1.000 ml/min.
  • Pressure Range: 0 – 40 MPa (0 – 6000 PSI).
  • Pressure Pulsation: Typically < 0.1 MPa or < 1.0%.
  • Dimensions: S 9425: 310 x 165 x 478 mm, S 9430: 396 x 165 x 478 mm.
  • Power Supply: 100 - 250 ~V (47 - 63 Hz).

Order Information
Various configurations are available for both S 9425 and S 9430 models, with options for Stainless Steel or PEEK materials across Micro, Analytical, and Preparative types. An integrated active piston back flushing system is optional.

Spare Parts
Spare parts include ceramic pistons and primary and secondary piston seals for micro, analytical, and preparative configurations.

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
