The Solinst 12V Submersible Pump 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.

The Pump’s sleek, short design ensures it fits easily down wells without hang-ups.

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.

Solinst 12V Pump Design and Operation

The Solinst 12V Submersible Pump 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.

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.

12V Submersible Pump Features

  • 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

12V Submersible Pump Applications

  • 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 or sand. Simply threads onto the Pump’s intake.

Tag Line: Convenient reel-mounted marked cable, for measured depth deployments.

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).

     A Model 800M Packer can be used to isolate the sampling zone and reduce purge volumes.

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.
