The SP20 stainless steel low flow submersible pump is designed specifically for underground water environments, with a small diameter and small-sized pump head, perfect for low flow sampling and well flushing work. All materials are made of stainless steel components, allowing for reliable sampling even in harsh environments. This pump works in conjunction with the SP10C controller. During the sampling process, the built-in sensors enable the operator to accurately control the flow rate of the pump. This pump has low energy consumption. With a 1000 watt gasoline generator and 4L of gasoline, the equipment can operate continuously for up to 18 hours at full power (usually, due to the controller being used to reduce sampling flow and using low-speed sampling, energy consumption is lower and the expected operating time will be longer).

Technical advantages:

• A low velocity sampling pump suitable for groundwater environments, capable of collecting groundwater samples from a distance of 50 meters (from the water surface to the ground),

Paired with an extended drop tube component, the sampling depth can be extended to over 200 meters

• Low speed sampling, flow rate can be reduced to below 100ml/min (under certain conditions)

• Dry conversion protection function

• Easy to clean and maintain, the motor can be replaced on site

• Portable handheld scroll/wheeled scroll

• Provide short circuit protection for your safety

• 2-line x 16 character numeric display

• Button up/down controls frequency modulation

• Internal processor saves individual well parameters
