Abstract
A positive displacement pump includes a suction cover disposed in a suction access bore defined in the fluid end and housing, where the suction cover is configured to cover the suction access bore. A retainer nut is configured for abutting against the suction cover and retaining the suction cover within the suction access bore. A suction gland has an inner circumferential threaded interface configured to engage an external circumferential threaded interface defined on the retainer nut, and the suction gland has a plurality of threaded openings configured to receive a plurality of threaded fasteners that can be used for securely fastening the suction gland to the fluid end housing.
Claims21
A pump having a fluid end housing comprising:
- a suction cover disposed in a suction access bore defined in a fluid end housing, the suction cover being configured to cover the suction access bore;
- a retainer nut configured for abutting against the suction cover and retaining the suction cover within the suction access bore;
- and
- a suction gland having defined therein a tubular cavity configured for being coaxially disposed within the suction access bore, the tubular cavity having an inner circumferential threaded interface configured to engage an external circumferential threaded interface on the retainer nut, the suction gland further having a plurality of threaded openings configured to receive a plurality of threaded fasteners configured for securely fastening the suction gland to the fluid end housing.
A modular suction gland assembly for a suction access bore defined in a fluid end housing of a reciprocating pump, comprising:
- a suction cover configured to cover the suction access bore;
- a retainer nut configured for abutting against the suction cover and retaining the suction cover within the suction access bore;
- and
- a suction gland having defined therein a plurality of threaded openings configured to receive a plurality of threaded fasteners configured for securely fastening the suction gland about the suction access bore, the retainer nut being rotatably engageable with a threaded cavity of the suction gland to retain the suction cover within the suction access bore.
A positive displacement pump having a power end coupled to a fluid end, the fluid end of the pump comprising:
- a plurality of pressure chambers defined within the fluid end;
- a plurality of suction access bores defined within the fluid end and each being in fluid communication with a respective one of the plurality of pressure chambers;
- a plurality of suction access ports defined in the fluid end each being in fluid communication with a respective one of the plurality of suction access bores;
- a plurality of suction covers each being disposed in a respective one of the plurality of suction access ports, each suction cover being configured to cover a respective suction access port;
- a plurality of retainer nuts configured for abutting against a respective one of the plurality of suction covers and retaining the suction cover within the respective suction access bore and covering the suction access port;
- and
- a plurality of modular suction glands each having defined therein a tubular cavity having an inner circumferential threaded interface configured to engage an external circumferential threaded interface defined on a respective one of the plurality of retainer nuts, each modular suction gland further having a plurality of threaded openings configured to receive a plurality of threaded fasteners configured for securely fastening the suction gland to the fluid end over a respective one of the plurality of suction access ports.
