HNA offers a full line of pistons for duplex and triplex mud pumps. All API types are available. Among these are:
Pistons with replacement rubbers.
Our premium pistons are fully interchangeable with other API standard designed pistons and deliver maximum performance in almost all drilling conditions. High tensile strength, resistance to chemicals, hydrocarbons, and abrasion, long lasting service, and full interchangeability with other API designed pistons make our premium piston a sound value.
Bonded Rubber Pistons
This one piece bonded constructed piston has no joints to leak. Eliminates abrasive fluids between piston and liner. The fluid expanded lip is not damaged by high pressure and fast pump strokes. This Fail-Safe piston seals off to greater diameter as liner wears
Premium Bonded Urethane Pistons
Currently running in pumps using exotic muds and highest drilling pressures! Bonded construction - no joints, no leakage. Longer piston and liner life. This piston will run in higher-pressure, fast stroking pumps, and is resistant to oil base muds and other additives currently being used. This Premium Piston has been in service for years, providing unmatched performance under extreme drilling conditions. This one piece bonded unit provides the same series of advantages., being imprevious to oil and other chemicals.
HNA also offers a full line of piston replacements including Piston Hubs, Plates, Snap rings and Replacement Rubbers.
The hub is formed from high grade steel.
The piston rubber is made from specially formulated compounds which are resistant to the effects of heat, oil and water. The multi-ply fabric reinforced backings used in the production of the piston rubbers provide positive, wear resistant seals.
