RP58 / 399 PMM ESP
We don’t sell ESP products.We sell ESP solutions.
A complete Reynolds artificial-lift string — pumps, gas separator, tandem seal, 399 permanent-magnet motor and sand control — engineered, machined and assembled in Texas. Scroll to descend the string.
Top of string
Discharge Head
Bolt-on discharge head ports produced fluid into the production tubing. Castellated cable guards and stainless bands protect the power cable across every flange on the way up the well.
- Connection
- Bolted flange
- Tubing
- 2-7/8" EUE
- Cable guard
- Castellated, 304 SS
Product · Electric Submersible Pumps
RP58 Multistage Pump
Five RP58 pump housings, sixty-seven stages each, lift the well. Reynolds-green exterior, machined-steel internals — paint stops at the flange face.
- Stages / housing
- 67
- Shaft
- 7/8" Inconel
- Bearings
- Tungsten-carbide ARM
- Range
- 58 series
Cross-section
Inside the stage
Mixed-flow impellers keyed to the shaft spin inside flush-stacked diffusers. Carbide ARM bearings every third stage hold the assembly true at 3,600 rpm. Toggle the cut to see it live.
- Impeller
- Mixed-flow, double-shroud
- Diffuser
- Flush-stacked, static
- Key
- 1/16" strip
Product · Gas Separation
Gas Separator
Screened intake, helical inducer auger and a rotary separator drum spin free gas out of the stream before it reaches the first pump stage — protecting lift efficiency in gassy wells.
- Intake
- Screened ring
- Separation
- Rotary drum + auger
- Bushing
- Carbide
Product · Seals & Protectors
Tandem Seal
Two identical seal sections — face seal, elastomer bag chamber, labyrinth — absorb thrust and isolate clean motor oil from well fluid. A tilting-pad thrust bearing rides at the top.
- Configuration
- Tandem (UT + LT)
- Thrust
- Tilting-pad + carbide runner
- Isolation
- Bag + labyrinth
Product · Permanent-Magnet Motors
399 PM Motor
A 3.99" permanent-magnet motor that turns more horsepower in a slimmer string than a comparable induction motor. Five modules, splined couplings, REYNOLDS LIFT — 100% MADE IN TEXAS cast into the housing.
- OD
- 3.99 in
- Type
- Permanent magnet
- Modules
- 5, splined
- Speed
- Variable, 0–3,600 rpm
Cross-section
Rotor, stator & windings
Surface PM magnets on a solid machined rotor, SKF tapered roller bearings, copper end windings and epoxy encapsulation. The permanent-magnet rotor is why the 399 runs cooler and slimmer. Toggle the cut.
- Rotor
- Surface PM, machined
- Bearings
- SKF tapered roller
- Windings
- Copper, epoxy-encapsulated
Product · Sensors
Downhole Sensor
Polished-stainless gauge package reading intake/discharge pressure, temperature, vibration and current leakage — the data feed behind Reynolds monitoring and optimization.
- Reads
- P / T / vibration / leakage
- Body
- Polished 316 SS
- Feeds
- Optimization platform
Product · Sand Protection
Sand Slayer
Bottom of the string: a passive sand-separation tool that drops solids out of the stream before they reach the pump — no power, no moving parts to wear, longer run life in abrasive wells.
- Type
- Passive separation
- Power
- None required
- Protects
- Pump & seal life
Designed · Engineered · Manufactured in Texas
One string. One source.
Every component you just descended past is built under one roof in Stafford, Texas. That is what lets Reynolds tune a complete lift solution to your well instead of forcing your well to fit a catalog.
Made in the USA, not overseas
Designed, engineered
and built in Texas.
Every Reynolds component is manufactured under one roof in Stafford, Texas, by a team with more than 150 years of combined oilfield experience. Owning the whole process means we tune a complete lift solution to your well instead of forcing your well to fit a catalog.
The complete string
One source for every component below the wellhead.
Electric Submersible Pumps
Multistage centrifugal pumps engineered for high efficiency and long run life across the full production range.
Gas Separator
Rotary gas separation that strips free gas before it reaches the first pump stage — protecting lift efficiency in gassy wells.
Seals
Tandem seal sections that absorb thrust and isolate clean motor oil from well fluid.
Permanent Magnetic Motors
Permanent-magnet motors that turn more horsepower in a slimmer string and run cooler than comparable induction motors.
Induction Motors
Rugged induction motors for operators standardized on conventional drives and infrastructure.
Sensors
Downhole gauge packages reading pressure, temperature, vibration and current leakage — the data behind optimization.
Sand Protection
Passive sand separation — the Sand Slayer — drops solids out of the stream with no power and no moving parts.
Variable Speed Drives
Surface VSDs tuned for ESP duty and the Reynolds permanent-magnet motor line.
ESP Cables
Flat and round power cable with the lead-sheath and armor construction downhole power demands.
