LD Class 12mL/min Flow Rate - Dual Piston Pumps for Low Pulsation Requirements

The versatile LD Class consists of dual-headed, positive displacement piston pumps, delivering unmatched performance for analytical, flash, and small-scale preparative chromatography applications. With the patented SSI low dead-volume Pulse Dampener, advanced cam technology and dual piston mechanism, the LD Class provides virtually pulse-free operation. The pumps are designed for high flow rate accuracy and low pulsation required for Analytical Liquid Chromatography (HPLC). Standard fluid path materials are Stainless Steel and PEEK, in addition to optional Titanium. 


  • Max. Flow and Pressure Ratings: 12 mL/min (6,000 psi)
  • Pulsation: ± 5% @ 1 mL/min and 1,000 psi (12 mL)
  • Pressure Accuracy: ± 1% of full scale pressure (12 mL)
  • Flow Accuracy: ≤ ±2% for a flow rate of 0.20 mL/min and above with 80:20 Water/IPA @ 1,000 psi
  • Jacketed heads for temperature controlled processes
  • Automatic pressure compensation
  • Pulse Dampener
  • Integrated Prime-Purge Valve
  • Interactive keypad control

The LD Class provides the precise flow and low pulsation for the most challenging separations.
