Low-Flow Groundwater Sampling Pump

低流量地下水采样泵

Monitoring well samples taken too fast pick up silt and lose volatiles, skewing dissolved metals and VOC results. Purge rate on this pump is 100–500 mL/min, sampling at up to 1.0 L/min, fitting wells of 50 mm and larger. Choose bladder, helical rotor or peristaltic type, and add a flow cell if you track stabilisation in the field.

Flow rate
0.1–1.0 L/min, adjustable
Pump type
Bladder, helical rotor or peristaltic
Maximum lift
Up to 60 m (submersible)

Product Description 产品描述

Monitoring well samples taken too fast pick up silt and lose volatiles, skewing dissolved metals and VOC results. Purge rate on this pump is 100–500 mL/min, sampling at up to 1.0 L/min, fitting wells of 50 mm and larger. Choose bladder, helical rotor or peristaltic type, and add a flow cell if you track stabilisation in the field.

Highlights

  • Bladder, helical rotor or peristaltic pump to suit depth and analytes
  • Submersible versions lift up to 60 m in 50 mm wells
  • PTFE or LDPE tubing chosen to limit sorption losses
  • Optional flow cell with pH, EC, DO, ORP and turbidity probes

Applications

  • Groundwater monitoring well sampling
  • Dissolved metals compliance sampling
  • Volatile organic compound groundwater samples
  • Landfill and contaminated site monitoring
