1500 Series HPLC Pumps

Waters offers affordable, high-performance binary and isocratic pumps that are easy to use and reliable. The integrated, high-pressure binary HPLC pumps feature on-board pulse dampening and efficient mixing; their pulse-free solvent flow makes them ideal for use with highly sensitive detectors. You can also obtain the same performance in an isocratic version. 

Pump Name Flow Rate
1525 Micro Binary HPLC PumpLow flow rates
1525 Binary HPLC PumpStandard analytical flow rates to Semi-preparative flow rates
1525 with Extended Flow Heads Standard analytical flow rates to Semi-preparative flow rates
1515 Isocratic HPLC PumpStandard analytical flow rates to Semi-preparative flow rates

The 1500 pump series also offers:

  • Precise stepper motor control (48 steps/µL resolution) of dual reciprocating pistons
  • Non-circular drive gears for smooth, uniform eluent delivery
  • Optional 1500 Series Column Heater with a temperature range of 20 to 60 °C to maintain accurate, consistent column temperature
  • Optional integral vacuum degasser (standard on the 1525µ) to remove dissolved gases from the mobile phase and improve performance and reliability
  • Optional automated seal wash to extend the primary seal life for reliable operation

The pumps are compatible with Waters Sample Managers, Detectors, and Waters software controls (Breeze™, Empower™, and MassLynx™). 


1515 Isocratic HPLC Pump Features an integrated, high-pressure, binary pump with on-board pulse dampening and efficient mixing. Its pulse-free solvent flow with analytical to semi-preparative flow rates are well suited for high sensitivity detectors.
1525 Binary HPLC Pump An integrated, high-pressure, binary pump with on-board pulse dampening and efficient mixing. Its pulse-free solvent flow with analytical to semi-preparative flow rates are well suited for high sensitivity detectors
1525 Micro Binary HPLC Pump A high-pressure, binary pump for LC/MS micro applications, with on-board pulse dampening and efficient mixing. Its pulse-free solvent flow with low flow rates are well suited for high sensitivity detectors
