Fluid liner wear indicator for suction manifold of reciprocating pump assembly
A manifold through which a fluid is adapted to flow. The manifold includes an elongated member at least partially defining a fluid chamber through which the fluid is adapted to flow, a longitudinal axis, and an interior surface; a fluid liner disposed within the fluid chamber and adapted to dynamically respond to pressure fluctuations within the fluid chamber as the fluid flows therethrough; and a wear indicator positioned radially between the interior surface of the elongated member and the longitudinal axis. The fluid liner is subject to wear and/or erosion due to the flow of the fluid therethrough and/or the dynamic response of the fluid liner to the pressure fluctuations within the fluid chamber. The wear indicator is adapted to indicate the degree to which the fluid liner has been subjected to the wear and/or erosion.
