Model 409 Portable Grundfos Pump
The Grundfos Redi-Flo2® Pump is an electric submersible pump well known for its high purge rates and ability to reduce to a low flow for sampling.
The pump is designed to fit inside a standard 2" monitoring well. The variable frequency drive converter will work with either 115 or 230 volt electrical supply. It can also accept a 4-20 mA signal from a pressure transducer or flow meter to regulate the pump during pump tests.
Solinst has built a rugged portable system which mounts the controller, reel, pump, Teflon® motor lead and tubing on a convenient hand cart.
Large pneumatic tires on the hand cart allow easy transport over rough terrain. The cart features an adjustable height tubing guide which protects the tubing and cable from damage on sharp edges of well casing.
The cart is designed for single person, field transportation and operation.

Dedicated Version
Solinst also offers the Redi-Flo2 with Teflon® motor lead and tubing combinations for dedicated installations. The Redi-Flo2 is approved by the EPA for all sampling parameters, including VOC's, trace metals, and dissolved gasses.
Redi-Flo4
For larger wells or higher flow rate requirements, the Red-Flo4 pump range is also available, with flow rates of up to 50 gpm and to depths of 600 ft. (180 m).
Other Portable Pumps
Solinst also supplies a variety of other portable pumps, including samplers for:
- depths up to 2000 ft. (600 m) and more
- applications as narrow as 3/8" (9.5 mm)
- VOC sampling, including Bladder Pumps
- discrete depth and below product layers
- inexpensive sampling
