Abstract
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.

A liner for a suction manifold adapted to provide fluid to a plurality of intake ports of a multi-unit reciprocating pump, said liner comprising:
- (a) a compressible, resilient body carried within said suction manifold;
- (b) said body having a lateral slot running through its upper portion defining, when said body is installed in said suction manifold, a generally U-shaped channel, said channel extending through said manifold and adapted to convey fluid from an inlet of said suction manifold to said intake ports of said pump units;
- and
- (c) wherein the cross-sectional area of said channel diminishes along the direction of flow through said channel.
A suction manifold adapted to provide fluid to a plurality of intake ports of a multi-unit reciprocating pump, said suction manifold comprising:
- (a) a manifold having an inlet;
- (b) a liner carried with said manifold, said liner comprising a compressible, resilient body defining a channel extending through said manifold and adapted to convey fluid from said inlet of said manifold to said intake ports of said pump units;
- and
- (c) a cap adapted for coupling to said inlet and to a suction line, said cap comprising a passage and a flow guide extending inwardly into said channel of said compressible body, wherein said flow guide comprises a radial enlargement adapted to engage a portion of said compressible body.
A suction manifold for a multi-unit reciprocating pump having a plurality of intake ports, said suction manifold comprising:
- (a) an inlet;
- (b) a liner comprising a compressible resilient body mounted within said suction manifold, said body defining a channel extending through said manifold and adapted to convey fluid from said inlet of said suction manifold to said intake ports of said pump units;
- and
- (c) a tapered shim installed in said manifold and supporting said compressible body of said liner under its distal end, wherein said shim is configured to provide said compressible body with a diminution of the cross-section area of said channel along the direction of flow through said channel.
