Liner for frac pump suction manifold
Frac pumps have liners for a suction manifold that is adapted to provide fluid to a plurality of intake ports of a multi-unit reciprocating pump. The liners comprise a compressible, resilient body. The compressible, resilient body is carried within the suction manifold. When installed in the suction manifold, the body defines a channel extending through the manifold that is adapted to convey fluid from an inlet of the suction manifold to the intake ports of the pump units. The cross-sectional area of the channel diminishes along the direction of flow through the channel.
