1. Smooth fluid delivery, 0.002 to 80 mL/min in various models using a reciprocating piston design.
2. High Pressure capabilities,  to 6000 psi.
3. Corrosion resistant materials.

Precision Metering

Optos Series metering pumps can be used wherever precise flow rate control, particularly at high pressures, is required.  Optos pumps are well suited for process control, petrochemical, reactant feed, and a wide range of laboratory applications.
Wide Flow Ranges
We manufacture a wide range of Optos Series pumps grouped into three pump models.  We can also customize our designs to meet your specific requirements.
Reciprocating Piston Design
All Eldex Optos precision metering pumps are based on a positive displacement, reciprocating piston design, which gives you precise flow control.  Various models cover flow rates from 0.002 to 80 mL/min.

Other Eldex pumps are available.  Our MicroPro pump delivers in the microliter per minute range and is based on a syringe design.  Our other ReciPro pumps cover slightly different flow rates than the Optos.

Positive Displacement, Reciprocating Piston assures precise metering.
30 Years of Experience
Eldex's Optos Series incorporates knowledge gained from over 30 years of experience in designing and manufacturing reciprocating piston pumps for a wide variety of applications, while integrating the latest technology and electronics.
Applications Include
Optos precision metering pumps are designed and ideally suited for numerous applications, including: Laboratory applications, including HPLC
Reactant/chemical feed
Column washing
Pilot plant/process control, including petrochemical
Post column reaction
Flow injection analysis
Versatile, Easy to Use
The Optos pump provides a simple interface for ease of control over flow rates, refill rates, compressibility compensation and other pump parameters.
The Optos pump is easy to use, with a clear LCD display and solvent resistant membrane keypad
Convenient Control Options
The Optos pump can be controlled from either the local LCD display and membrane keypad, or remotely, using either RS232 commands or analog controls (either 0-5VDC or 4-20mA).
Remote control options include RS232 and analog controls.
Corrosion Resistance
The materials in the liquid end of the Optos Series pumps are carefully chosen for corrosion resistance.  The piston is sapphire, and the inlet and outlet valves incorporate sapphire seats and ruby balls.
Non Metallic
Optos Series metering pumps can be made with PEEK liquid end assemblies, as opposed to the usual type 316 stainless steel, eliminating all metal contact in the flow path.
Piston wash
The use of buffers or solutions which crystallize when exposed to air can lead to abrasion of the piston seal.  A fully integrated piston wash system is included in the Optos pumps, dramatically extending piston seal life.
Upgrade to Plus
Plus versions of Optos Series pumps come with an integrated pulse damper to further reduce pulsation, and the ability to monitor pressure and set high and low pressure limits.
Left side shows pulsation without Plus, right side with Plus.
Simple, robust construction
The Optos Series pump, only four inches wide, occupies very little bench space.  The design is simplified for optimal reliability.  With our extensive experience in reciprocating pump technology, no effort has been spared to make the most durable pump available.
Three Models, Three Interchangeable Pump Heads
There are three different models based on a stroke length, each covers a specific flow and pressure range.  If possible, choose a model you will use in the upper range of its flow rate capacity.
Three different, interchangeable liquid ends are available with each model, greatly expanding the flow rate capabilities of the pumps.
Choose from one of the three Optos Series for additional details and specifications (try to choose a pump you will use in the upper range of its capacity):
Model 1
The Model 1 pumps have flow rate ranges from .002 to 20 mL/min. at pressures up to 6000 psi, depending on the liquid end.  Optimal at lower flow rates (e.g., 0-5 mL/min).
Model 2
The Model 2 pumps have flow rate ranges from .003 to 40 mL/min. at pressures up to 6000 psi, depending on the liquid end.  Optimal at medium flow rates (e.g., .5 - 10 mL/min).
Model 3
The Model 3 pumps have flow rate ranges from .01 to 80 mL/min. at pressures up to 6000 psi, depending on the liquid end.  Optimal at higher flow rates (e.g., 5 - 80 mL/min).
