Piston pumps are reciprocating-type, positive displacement pumps that move fluid by trapping a fixed amount and forcing it through the discharge port. These pumps are the longest lasting and have the widest variety of configurations and material choices on the market.

• Dispense fluid at 100, 250, 500, 1,000, 2,500, and 5,000 microliters (µL)
• Full dispense volume precision of <0.5% CV
• Accurate to 99.5 percent at 2 percent to full dispense volume
• Pressure rated up to 500 psi (contact us today for high pressure applications)
• Full stroke of 12.7 mm
• Available in acrylic, PEEK, and Ultem head materials and zirconia, ceramic, and PEEK piston materials
• Accurate to 10-million cycles in water and 5-million cycles for more aggressive fluids
• Choose from a variety of innovative design styles:
• Maestro: Minimal backlash with twice the longevity of competitors for diagnostic and low-pressure applications
• Ultra: Proprietary hydrophobic construction reduces salt buildup for 100 times the life in aggressive fluids compared to competitive pumps
