Sampling Pump System

Keck SP
12 Volt Submersible Sampling Pumps

The Keck SP Submersible Sampling Pumps are designed for efficient low flow purging and sampling of groundwater monitoring wells. Keck’s special pumping head allows finely grained material to pass through without clogging the unit. No special tools are required for maintenance and each pump can be easily disassembled for decontamination. Available on a reel, backpack, and a portable model that can be used as a dedicated system.

• Constructed of inert materials to protect against rugged field conditions
• 1.75 inch O.D. diameter ideal for 2" diameter wells
• 12 Volt DC powered
• Variable Speed
• Uniform continuous flow
• Low velocities and agitation, ideal for sampling and purging
• Progressive cavity pumping head (rotor and stator)
• Modular construction for ease of cleaning in the field
• Continuous operation for mini-aquifer tests

Grundfos Redi-Flo2®

The Grundfos Redi-Flo2® Electrical Submersible Pump provides smooth, uninterrupted water flow during groundwater sampling or conducting aquifer tests to depths down to 280 ft. Both high flow rates needed for purging and low flows recommended for sampling are achieved with the same pump.
Designed for long-term reliability in dedicated monitoring wells, the Redi-Flo2® provides optimal sample quality with either traditional purging prior to sampling or low draw-down passive sampling when operated with the Redi-Flo VFD (Variable Frequency Drive).

• Purging and sampling with the same pump is extremely efficient.
• The unique design and superior materials allow for easy operation, decontamination and maintenance as well as disassembly and re-assembly.
  
• All replacement and maintenance parts for the Grundfos Redi-Flo2® are immediately available at Geotech Environmental Equipment, Inc. a certified Grundfos Master Distributor.

Grundfos Redi-Flo VFD

• Precise Flow Control
  The push button control pad provides greater control over the discharge flow rate for better accuracy and precision during sampling.
  
• Wide Performance Range
  Not just one performance curve:  the Redi-Flo VFD covers a range of performances and can function at any point of operation within that range.
  
• Dual Input Power Capability
  Either 120V or 230V, single-phase AC input power is accommodated simply by changing the power cord terminations.
