Solinst 12V Submersible Pump Groundwater Samplers provides an efficient means of purging and obtaining groundwater samples from monitoring wells.
The 12V Submersible Pump and 12V Pump Controller are lightweight, portable, and easy to set up, deploy and operate. There is also the option to dedicate the pump using a specially designed well cap. The Pump’s sleek, short design ensures it fits easily down wells without hang-ups.
About of Solinst 12V Submersible Pump Groundwater Samplers
The Solinst 12V Submersible Pump is capable of pumping groundwater from 36.5 m (120 ft) below ground surface, with flow rates up to 13.5 L/min (3.6 US gpm) in shallow conditions.

The Solinst 12V Submersible Pump is capable of pumping groundwater from 36.5 m (120 ft.) below ground surface, with flow rates up to 13.5 L/min (3.6 US gpm) in shallow conditions. The continuous flow rate is very simple to adjust using the 12V Pump Controller’s single dial. The 12V Submersible Pump’s sleek, short (nominal 6″) design means it fits easily down wells that may not be straight, without hang-ups.
Solinst 12V Submersible Pump Groundwater Samplers Design and Operation
Solinst 12V Submersible Pump Groundwater Samplers system comprises the 12V Submersible Pump with cable, 12V Pump Controller, sample tubing (sold separately), and a user-supplied power source.
The 12V Submersible Pump cable simply connects to the 12V Pump Controller, which then clips to a 12V power source (sourced separately). The 3/8″ (9.5 mm) ID LDPE sample tubing is pushed onto the barbed fitting on the 12V Pump.
Convenient LED lights on the Controller indicate the status of the 12V Submersible Pump system, including high or low battery voltage, proper battery connection, normal operation and maximum flow rate. It has an easy-to-reset circuit breaker (no fuse to replace).
Simply turn the dial on the 12V Pump Controller clockwise to increase the voltage to the Controller, which turns the Pump’s motor faster and increases the flow rate.
Features of Solinst 12V Submersible Pump Groundwater Samplers
- Very simple to operate and adjust from high to low flow rates
- Smooth, short (6″ nominal) Pump design avoids getting stuck in wells that aren’t straight or plumb
- Fits inside Nominal 2″ OD Sched. 40 or 80 PVC Pipe
- Convenient LED light indicates 12V Pump Controller status and Pump operation
- Lightweight, compact, portable system; also a dedicated well cap option for longer term projects
Applications of Solinst 12V Submersible Pump Groundwater Samplers
- High and low-flow groundwater sampling for general chemistry
- High purge rates ideal when sampling using three volume purge protocol
- Useful when performing constant head tests in environments with high K (hydraulic conductivity)
Accessories and Power Options
- Packers: Save time and reduce costs by isolating sampling zones and minimizing purge volumes. The 800M Mini Packer Assembly is designed to easily connect directly to the Pump’s intake using an adaptor.
- Disposable In-Line Water Filter: For use in environments with high suspended solids. Ideal for preventing sand ingress to the pump. Simply threads onto the Pump’s intake.
- Tag Line: Convenient reel-mounted marked cable, for measured depth deployments.
- Dedicated 2″ Well Cap: For longterm monitoring projects and to avoid cross-contamination or decontamination between wells, a 2″ well cap assembly is available for dedicated deployment of the 12V Pump. The assembly includes a hanger bracket to support the Pump weight and quick-connect fittings for the sample tubing. It also accommodates the Pump cable and connector to the 12V Pump Controller. There is an access hole to fit a Solinst Water Level Meter or Levelogger. Adaptors to fit 4″ wells are also available.
- Power Source: A 2.3 m (7.5 ft) power cord uses alligator clips to connect to almost any 12 volt DC power source that can supply at least 45 amps at maximum draw (such as a deep cycle 60 amp AGM battery or higher, or a car, truck or marine battery).

How Does the 12V Submersible Pump Work?
The 12V Submersible Pump connects to the 12V Pump Controller, which then clips to a 12V power source. 3/8″ (9.5 mm) ID LDPE sample tubing is pushed onto the barbed fitting on the 12V Pump. The dial on the 12V Pump Controller is turned clockwise to increase the voltage to the Controller, which turns the Pump’s motor faster and increases the sample/purge flow rate.
Applications that the 12V Submersible Pump is Suited For:
- High and low-flow groundwater sampling for general chemistry
- High purge rates when sampling using three volume purge protocol
- Performing constant head tests in high K (hydraulic conductivity) environments
