These simple to use 12V submersible pumps provide the flow rates and control needed to purge and sample groundwater from boreholes at depths of up to 30 metres.
The Waterra range of WaSP 12V submersible pumps are used to purge and sample groundwater from boreholes. They are simple to use, and with the addition of a WaSP-F1 Low Flow Controller, provide the groundwater professional with the ability to sample at low or high flow rates.
The optional Waterra WaSP-F1 low flow controller is the ideal accessory for the WaSP 12V submersible pump. See separate data sheet for details.
The pumps are also characterised by their long service life of 400 hours. This is up to 100% longer than that of pumps from other suppliers.
P2, P3 and P5 have an outer diameter of 46 mm and are therefore suitable for measuring points with a diameter of 50 mm or more. The N21 can be used for narrower measuring points.
Every pump is delivered with a sufficiently long lead so that its maximum delivery height can be utilised no cables need to be joined together. All pumps require discharge hoses with 10 mm inner diameter to transport water. Hoses and cable ties for all WaSP submersible pumps are ordered and delivered separately.
