Description
The “ml” Syringe Pump Module is designed as a low cost, highly precise, single syringe infuse/withdraw pump capable of low to moderate back pressures.
There is one version of the “ml” Pump Module available at this time. A dual “ml” Pump Module version can be produced upon customer request. Typically, the “ml” Modular Pumping Component holds one syringe of any make, from 0.5ul to 60ml. The inside diameter of the syringe and desired flow rate are entered via your PC, and the internal microprocessor drives a precision stepper motor to produce accurate fluid flow. This unit is designed to operate inside an enclosure, cabinet, or on top of a bench. The board may be removed for “remote” operation.
- RoHs compliant
- Low cost syringe pump
- Ideal pump for do-it-yourselfers and OEM equipment designers
- Easy to incorporate legendary syringe pump technology into your equipment
- Precisely dispenses milliliter volumes
- Smooth flow
- Nonvolatile memory
- Two modes of operation
- Constant flow rate
- Volume dispense
Two Modes of Operation – Constant Flow Rateand Volume Dispense
The “ml” Pump Module will operate continuously in RATE mode or accurately dispense a specific amount of fluid in VOLUME mode. When starting the pump, RATE mode will be the default mode. To operate in Volume mode, set a target volume and the pump will change modes to suit the desired operation. This is the safest way to use the “ml” Pump Module. The pump will automatically stop when target volume is dispensed.
Smooth Flow
New micro-stepping pump profiles deliver very smooth and consistent flow.
Location Requirements for the Syringe Pump
This pump module was designed to operate inside an enclosure, cabinet, or on top of a bench/table. The circuit board may be removed to a “remote” location if desired.
- The pump must be integrated to a sturdy, level, clean and dry surface
- Minimum of one inch (2.5cm) clearance around the pump
- Adequate power supply
- Operating temperature 0° to 35°C (32° to 95°F)
- Relative humidity 20% to 80%
