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

Applications
- HPLC
- Reactant/chemical feed
- Column washing
- Pilot plant
- Post column reaction
- Flow injection analysis



High-Pressure Injection Pump Model:
Low Flow | Standard Flow | High Flow | |
---|---|---|---|
Model 1 Flow Rate: 0.002-20 mL/min Optimal at lower rates (0-5 mL/min) | Order Code: 1L Flow: 0.002-2.5 mL/min 6000 psi | Order Code: 1S Flow: 0.003-5 mL/min 6000 psi | Order Code: 1H Flow: 0.01-20 mL/min 3000 psi |
Model 2 Flow Rate: 0.003-40 mL/min Optimal at medium rates (1-10 mL/min) | Order Code: 2L Flow: 0.003-5 mL/min 6000 psi | Order Code: 2S Flow: 0.01-20 mL/min 6000 psi | Order Code: 2H Flow: 0.04-80 mL/min 1500 psi |
Model 3 Flow Rate: 0.01-80 mL/min Optimal at higher rates (5-80 mL/min) | Order Code: 3L Flow: 0.01-10 mL/min 3000 psi | Order Code: 3S Flow: 0.01-20 mL/min 1500 psi | Order Code: 3H Flow: 0.04-80 mL/min 750 psi |
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.
