Abstract: A replaceable DC electric motor and kit for a groundwater sampling and pumping device and system for withdrawing groundwater from a well. The motor is provided with means to align the motor with an alignment pin in the groundwater sampling device.
Abstract: A groundwater sampling and pumping device and system for withdrawing groundwater from a well of small size, not exceeding 1.5 inches I.D. The device includes a hollow outer housing having water inlet ports formed through a bottom thereof and a hollow inner housing sized to be positioned integrally within the outer housing and defining a water flow passage therebetween. An electric motor in the inner housing is connected to a water impeller operably positioned to draw groundwater into the water passage. The water passing upwardly through the water flow passage provides cooling for the motor. Preferably the housing is formed of a polymer material, and/or a metal, such as stainless steel.
Abstract: The invention is a non-metallic, preferably, plastic container for delivering oxygen generating materials (OGMs) into wells. By constructing the canister of a plastic and sealing the ends, the canister can be disposable or reusable.

Abstract: A groundwater sampling and pumping device and system for withdrawing groundwater from a well. The device includes a hollow outer housing having water inlet ports formed through a bottom thereof and a hollow inner housing sized to be positioned coaxially within the outer housing and defining a water flow passage therebetween, the respective bottoms being spaced to define a lower portion of the water passage whereby water ports are in fluid communication with the water passage. An electric motor in the inner housing is connected to a water impeller operably positioned between the bottoms to draw groundwater into the water passage.
