End-suction centrifugal pumps - Dimensions of cavities for mechanical seals and for soft packing 1 Scope This standard specifies the terms and definitions of mechanical seals and soft packing of end-suction centrifugal pumps (hereinafter referred to as pumps), dimensions of seal cavity and gland plate attachments, and design requirements of seal cavity. This standard is applicable to pumps for general purpose and heavy-duty process applications. This standard is not applicable to mud pumps and impurity pumps. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. GB/T 5656 Technical specification for centrifugal pumps - Class II GB/T 5657 Technical specifications for centrifugal pumps (Class III) GB/T 6556 Type, main dimension, material and marking of mechanical seals GB/T 16907 Technical specifications for centrifugal pumps (Class I) 3 Terms and definitions For the purposes of this standard, the following terms and definitions apply. 3.1 cartridge mechanical seal sealing member which is pre-assembled and adjusted before installation, including mechanical seal, gland plate, shaft sleeve and a mating ring 3.2 flush flow of fluid introduced into the seal cavity on the process fluid side, in close proximity to the sealing faces, and usually used for cooling the mechanical seal and continuously removing vapour or contaminants from the seal cavity 3.3 gland face mounting arrangement and equipment surface to which the seal gland plate is clamped 3.4 seal cavity fluid-filled space contained by the seal chamber Note: The mechanical seal rotates in the seal cavity.
