APT Full open valve and seat is designed designed for Maximum Flow Characteristics with the combination of strength of a forged alloy steel upper body with precision casting to minimize flow restriction and fluid turbulence.
APT Four-web valve and seat is designed for maximum flow characteristics by adopting premium forged steel with the performance of high strength and high hardness. The rubber is fixed on the valve body, the seats have high strength and resistance to impact, suitable for high pressure jet drilling.
APT Three-web valve and seat is designed to enable maximum flow charactristcs, offering additional bearing area for valve that minimize stress and promotes a long service life.
APT premium replacement pistons, fully interchangeable with other API standard designed pistons.
Rubbers are made with tough and durable Buna N Rubber for all pressures, ideally suited for either oil-base or water-base mud. The special processed fabric provides an unusual waterproof bond of seals to piston which assures a longer life with high tensile strength rated with resistance to chemicals, hydrocarbo for all drilling conditions.
The one-piece bonded comstructed piston is desiged and manufactured to handle the tough assignments encountered during ladn and offshore drilling. A spcecial processing of the fabric eliminates leakage points and resistance to abrasion. The fluid expanded lip is not damged by high presure and fast pump strokes. The Fail-Safe piston seals off to greater diameter as liner wears.
High Temprature Urethane Bonded Piston is designed to perform in the harshest of drilling conditions with compatible applcations and mud types.
Green Duo Urethane Bonded Piston is constructed of oil-resistant polyurethane bonded to a solid metal hub, offering a longer service life than replacment rubber pistons. As fluid pressure increases, the urethane surface of the piston expands against the liner to complete the seal, even in the enlarged diameter of a worn liner bore.
Engineered to perform in the harshest drilling conditions, APT “Bullnose” is composed of multi-durometer bonded urethane for superior performance with longer life.
Piston rods are made with premium grade, heat treated alloy steel, offering excellent resistance to fatigue, corrosion and heavy loads. A full line of piston rods are available for various pumps.
