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 pumps
are designed and ideally suited for numerous applications,
including: |
 HPLC |
| Reactant/chemical
feed |
| Column
washing |
| Pilot
plant |
| 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. |
|
|
|
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. |
|
|
|
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. |
|
|
|
Plus:
Minimize
Pulsation, Monitor Pressure |
|
|
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. |
|
|
|
|
|
Option: Three
Interchangeable Pump Heads |
|
|
|
| To maximize
the versatility of the Model 1LIP Optos pump, two
additional different liquid end assemblies are
available.
Each interchangeable liquid end provides specific flow
rates and pressure capabilities and can be changed in a
matter of minutes.
The Model 1LIP comes with
a 3/32" piston and pump head. The optional
heads use 1/8" or 1/4" pistons and pump
heads. To purchase the optional 1/8" parts,
order P/N 5820 (piston) and P/N 5906 (pump head).
To purchase the optional 1/4" parts, order P/N 5821
(piston) and P/N 5907 (pump head).

Optos
Series metering pumps can be made with type 316 stainless steel liquid end
assemblies, as opposed to PEEK. For the stainless steel version of this model, click on 1LMP. |
