- Requirements for peristaltic pumps: Clean sampling process with no cross-contamination, high repeatability, high suction lift for remote field sampling, and simple operation and maintenance.
- Applicable scenarios: Groundwater sampling, surface water sampling, sewage or water quality sampling, vacuum sampling, and sample injection during pressurization.
- Advantages of peristaltic pumps:
1) Low voltage operation (12V or 24V), allowing operation outdoors with temporary power supply;
2) Liquid only contacts the peristaltic pump tubing, eliminating the risk of cross-contamination of sample liquid;
3) Simple and convenient tubing replacement, easy maintenance, no dead angles or sealing structures;
4) The K25S peristaltic pump has a suction lift of up to 8.2 meters, convenient for actual field surface water and shoreline sampling;
5) Fixed-speed or variable-speed motors are available, providing precise and controllable sampling or injection flow rate with repeatability of ±0.5~±3%.
