Teledyne LABS ReaXus® reciprocating pumps covers a broad range of application needs, ranging from 5 mL/min to 300 mL/min and up to 6,000 psi. Whether you need low pulsation​ or are working with hazardous materials, the ReaXus line has an option for you. The single piston models are targeted towards moving material or providing pressure. The dual piston models are focused on continuous processing applications where a steady flow of material is important.

The ReaXus product line is low maintenance and requires no calibration like other styles of pumps, saving your organization time and money.​
