Plungers that keep pumping through sand and gas

Grooved, Monel-coated and PA ringed plungers per API-11AX — with controlled fits and coatings to match your fluid, solids and gas profile.

Plungers for real-world rod-lift conditions

We configure plungers around the well: solids loading, gas cut, viscosity, temperature and sour service. Geometry, metallurgy and inspection are tuned for uptime and predictable performance.

Engineered options include grooved plunger bodies to mitigate sand packing, corrosion-resistant Monel surfaces for brine/H₂S, and PA ringed designs that lift fines while keeping the barrel clean on every stroke.

Core plunger types

Pick the profile that matches your well — or tell us your conditions and we’ll recommend fits and coatings.

Plunger Type	Key Features	Recommended Use
Grooved Plunger	Longitudinal grooves disrupt sand packing between plunger and barrel, stabilize lubrication film and reduce sticking.	Wells with elevated sand/solids; applications seeking longer run life and steadier volumetric efficiency.
Monel-Coated Plunger	Corrosion-resistant Monel overlay significantly extends service life in sour/briny environments with abrasive fines.	Corrosive and abrasive wells, including H₂S exposure (per NACE guidelines) and high TDS fluids.
PA Ringed Plunger	20/40/60 grooves with split nylon rings resistant to chemicals and abrasion; rings help lift sand/silt while wiping the barrel.	Wells with intermittent sand production; need for barrel cleaning each stroke and stable pump fill.

Also available: spray-metal/carbide overlays, chrome/nitride surfaces and hardened substrates for higher temperature or crooked-hole service.

What makes our plungers last

Tight geometry + right materials + documented inspection — the trifecta for fewer workovers.

Controlled Fits & Clearances Fit options (e.g., Fit-1…Fit-5) tuned to fluid viscosity, gas and solids content for sealing without excessive drag.

Surfaces & Coatings Chrome/nitride, spray-metal or carbide overlays; Monel for corrosion resistance; ring materials matched to chemistry.

Materials & Hardness Alloy steels with targeted hardness; compatible with nitrided/honed barrels for smooth stroke and low wear.

QA & Traceability In-process and final dimensional checks; serial numbers and batch records available on request.

Application-driven configuration

Tell us what you’re running now and where it fails. We’ll propose a plunger type, fit and surface package to address it — and we’ll document every step so crews know exactly what they’re installing.
