OTECO’s innovative bonded polyurethane piston dramatically extends service life in triplex mud pumps with ample water cooling. Harder, more dense polyurethane construction provides superior resistance to abrasive fluids providing optimum service life in harsh drilling conditions. In addition, the urethane construction is especially resistant to chemicals and oil based drilling muds with varying aniline points. The multi-ply, fabric reinforced backing used in the production of the piston rubbers provide positive, wear resistant seals. High tensile strength, resistance to chemicals, hydrocarbons, and abrasion, long lasting service, and full interchangeability with other API designed pistons make the OTECO Premium piston a sound value.
The OTECO premium stem guided valve and seat features an extra wide metal to metal seal on the valve flange. The serrated upper surface on the valve gives a longer non-breathing seal between valve body and insert while the rigid seat cross-arms give greater strength and positive sealing. The strong, thick, valve knock off nut holds the insert tightly reducing flex and breathing which lessens the chance of foreign matter getting between valve and insert. The premium stem guided valve and seat provide good value at an economical price and weigh less than many competitors valve and seat.
