RediFlo2 (MP1) Pump and Hand Reels
The RediFlo2 (MP1) is a stainless steel and PTFE electrical submersible pump that purges and samples with the same unit. Flow ranges from 8 GPM (30 LPM) down to 100 mL/min under the Geotech VFD, so you can move casing volumes quickly and then drop to a stabilised low-flow rate without pulling the pump or swapping equipment. At 1.81" (4.6 cm) diameter it enters any 2" or larger well, and it operates to 280 ft (85 m).
Manufactured by Eijkelkamp (Eijkelkamp Soil & Water) as the MP 1 / Redi-Flo2. Previously built by Grundfos — the pump, part numbers and service kits are unchanged.
Choosing an option
Every option below includes the pump. The hand reel versions add a gray hand reel wound with an all-in-one motor lead — motor cable and integrated stainless safety cable in a single run — in the length you select. Choose the lead length to reach your deepest well plus working slack at surface. Pump Only suits a dedicated installation or a replacement for an existing reel.

- Electrical — 5 HP / 220 V / 3 PH / 400 Hz / 5.5 A, thermal overload protected at 176°F (80°C)
- Fluid temperature — 34–80°F (1–28°C); motor lubricating fluid is deionized water
- Lead lengths — custom lengths available in 1 ft increments from 30 to 300 ft
Completing your system
Everything listed here is in Redi-Flo2 (MP1) Parts & Accessories.
Required
- Variable Frequency Drive — 115 V or 230 V; sets discharge rate from 8 GPM down to 100 mL/min
- 1/2" x 5/8" discharge tubing
- 15 ft extension cord — connects the VFD to the reel
- Cooling shroud — required in any well 4" or larger. In 2" wells the passing water cools the pump automatically; in wider casings it can overheat and suffer permanent damage.
Also available — GeoReels with discharge tubing already fitted (LDPE, FEP lined PE, PTFE or PVC Nylobraid, 100–300 ft), cable guard, stainless steel check valve, and the full range of replacement parts and service kits.
