 1. Reliable, precise flow rate control to 144 mL/min with reciprocating piston design
 2. High pressure capabilities, up to 5000 psi
 3. Corrosion resistant materials
 4. Remote control options
Eldex metering pumps can be used wherever precise flow rate control, particularly at high pressures, is required.
We manufacture a wide range of ReciPro pumps grouped into three different pump families; the Optos Series, the HP Series and the VS Series.  We can customize our designs to meet your specific requirements.
All Eldex ReciPro metering pumps are based on a positive displacement, reciprocating piston design, which gives you precise flow control.
Eldex ReciPro pumps are capable of flow rates ranging from 0.02 to 144 mL/min at pressures up to 5000 psi.  Our ReciPro products include single piston pumps (A, B), dual piston pumps (AA, BB) and triple piston pumps (BBB).  The Optos Series Pumps are single piston, with optional pulse dampers for reduced flow fluctuations.
Pumps with multiple pistons have their channels out of phase for minimized pulsation, and can be operated either independently, or, with the use of a manifold, in parallel.
ReciPro pumps are designed for, and ideally suited to numerous applications, including: HPLC
Reactant feed
Column washing
Pilot plant
Post column reaction
Flow injection analysis
Choose from one of the two ReciPro series for additional details and specifications:
Optos Series
The Optos Series has pumps with flow rates between 0.002 to 80 mL/min.  Flow rates are electronically controlled and an optional pulse damper is integrated to reduce flow fluctuations and provide for pressure limit control.
HP Series
The HP Series has pumps with flow rates between 0.02 to 100 mL/min.  Flow rates are controlled via a precision micrometer.  The HP Series has been manufactured since 1978, assuring reliable, economical performance.
VS Series
The VS Series has pumps with flow rates between 0.025 to 144 mL/min.  Flow rates are set using a remote signal, or local potentiometer.  Precision micrometers can be added to expand the low flow rate range of the pumps.  VS Series pumps are ideal where remote control of flow rates is necessary, or, with the optional micrometer, when an expanded flow rate range is needed.
