Plunger Pumps

Plunger Pump Seals

FTL develops high‑performance sealing systems for plunger pumps in extreme applications such as cementing, fracking, high‑pressure water‑jetting, and ultra‑high‑pressure industrial systems up to 3,500 bar.

Our materials and spring‑loaded, solid packing designs deliver reliable sealing under high loads, abrasive media, aggressive chemicals, and continuous duty, eliminating lubrication and extending service life.

We work with OEMs to tailor each system to pump geometry, speed, and installation needs, ensuring simple assembly and consistent high‑pressure performance.

High-Pressure Seals

High‑pressure plunger pump seals are designed to match pump tolerances and geometry, using specialised materials to maintain reliable sealing and smooth operation under extreme pressure.

Crosshead Seals

Crosshead seals are vital to plunger pump reliability, protecting the power end by preventing ingress and retaining oil. With the right materials and design, they ensure clean, efficient, and consistent pump operation.

Low Pressure Seals

Low‑pressure seals support the high‑pressure system by managing lubrication and fluid flow ahead of the main seal, improving stability and extending component life.
