Function：Non-Voc sampling of groundwater, also be usedfor Voc sampling without airbag pumps.
Advantage：Wide flow range: 10ml-3000ml/min; The flow rate is stable and adjustable and it is suitable for chinese well.
Introduction
Functions: Groundwater well sampling，washing. Wide flow range, 0.1-12L/min
Advantages: High-flow well washing, low-flow sampling, dual-purpose pump; Standard lift of 70 meters, 300 meters in use at the Fourth Academy of Nuclear Science and Technology
Features:
1) Compared with imported pumps, the flow rate is twice as high, and the lift is 50% higher. Currently, there are users using it at 300 meters.
2) Uses a composite cable with meter markings, allowing you to see the depth of the pump head underground, unlike imported pumps which lack meter markings.
3) As an underground water sampling pump, it is distinctly different from traditional submersible pumps and does not cause secondary pollution.
