High-Pressure Injection Pump

Eldex's Optos Series incorporates knowledge gained from over 40 years of experience in designing and manufacturing reciprocating piston pumps for a wide variety of applications while integrating the latest technology and electronics. Compare with traditional injection pump, high-pressure injection pump has many advantages.

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

High-Pressure Injection Pump Advantages

1. Precise Metering

High-pressure Liquid Metering Pump can use for precise flow rate control, particularly at high pressures.

2. Wide Flow Ranges

Three pump models to meet your specific requirements.

3. Reciprocating Piston Design

All 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.

4. Versatile, Easy to Use

The pump provides a simple interface for ease of control over flow rates, refill rates, compressibility compensation and other pump parameters.

5. Convenient Control Options

The 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).

6. Corrosion Resistance

The materials in the liquid end of pumps are carefully chosen for corrosion resistance.  The piston is sapphire, and the inlet and outlet valves incorporate sapphire seats and ruby balls.

7. Non Metallic

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.

8. 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 pumps, dramatically extending piston seal life.

9. Simple, Robust Construction

The 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.
