The Mission piston is designed for use in the most demanding applications. The replaceable seal element is manufactured from a specially formulated elastomeric compound designed to be resistant to most chemical compounds found in the drilling industry today. This compound can also be utilized in conditions where elevated temperatures can be problematic to other types of pistons on the market.
The fabric anti-extrusion device on the piston is constructed from proprietary materials utilizing a patented process to reduce the extrusion of the rubber even at the pump’s maximum pressure rating.
The Mission piston body is manufactured from a high strength alloy steel forging and heat treated for durability. Mission piston bodies feature two wear indication grooves located on the flange to provide the customer with the information needed when rubber kits are installed on the used body. The deeper wear groove is for pressures up to 1500 psi, the shallow groove for pressures from 1500 to 2500 psi. If any of the portion of the flange is not worn past these indicator marks for the respective pressure, a new rubber kit can be installed on the piston hub. NOV Mission does not recommend changing rubber kits on piston bodies when the operating pressures exceed 2500 psi.
