SPECIFICATION
Use the following matrix to select the Model and Liquid End combination:
Pick the Model and Liquid End combination best suited to your ow range and pressure requirements; try to choose a combination you will use in the upper range of its ow capacity.
| Model 1 | Low Flow Liquid End |
| Flow rates from .002 to 20 mL/min Optimal at lower rates, e.g., 0-5 mL/min | Flow: .002-2.5 mL/min. @ 6000 psi Order code: 1L |
| Standard Flow Liquid End | High Flow Liquid End |
| Flow: .003-5 mL/min. @ 6000 psi Order code: 1S | Flow: .01-20 mL/min @ 3000 psi Order code: 1H |
| Model 2 | Low Flow Liquid End |
| Flow rates from .003 to 40 mL/min. Optimal at medium rates, e.g., 1-10 mL/min. | Flow: .003-5 mL/min. @ 6000 psi Order code: 2L |
| Standard Flow Liquid End | High Flow Liquid End |
| Flow: .01-10 mL/min @ 6000 psi Order code: 2S | Flow: .02-40 mL/min @ 1500 psi Order code: 2H |
| Model 3 | Low Flow Liquid End |
| Flow rates from .01 to 80 mL/min. Optimal at higher rates, e.g., 5-80 mL/min. | Flow: .01-10 mL/min @ 3000 psi Order code: 3L |
| Standard Flow Liquid End | High Flow Liquid End |
| Flow: .01-20 mL/min @ 1500 psi Order code: 3S | Flow: .04-80 mL/min @ 750 psi Order code: 3H |
Select Material for chemical compatibility best suited to your application:
Stainless steel: Wetted parts include type 316 stainless steel, sapphire, ruby, CTFE, gold, UHMW Polyethylene (consult factory for possible options). Order Code: M
PEEK®: Wetted parts include PEEK®, sapphire, ruby, UHMW Polyethyene, inert polymers (maximum pressure on PEEK® pumps is the lower of either 4000 psi or the rating shown in the matrix). Order Code: I
Upgrade to Plus for pressure control and pulse dampening:
Includes integrated pulse damper for smooth ow, pressure monitoring, ability to set high and low pressure limits.
Note: Not available on Model 3 or High Flow Liquid End pumps. Order Code P
