Vertically Suspended Pumps

Except for vertically suspended pumps, casings shall be designed to permit removal of the rotor or iimer element without discoimecting the suction or discharge piping or moving the driver. [Pg.20]

Steel and alloy steel horizontal pumps, and their baseplates, and vertically suspended pumps shall be designed for satisfactory performance when subjected to the forces and moments in Table 2-1A (2-IB). For horizontal pumps, two effects of nozzle loads are considered Distortion of the pump casing (see 2.2.8) and misalignment of the pump and driver shafts (see 3.3.5). [Pg.23]

Except for vertically suspended pumps (see 5.3.2 2), shafts shall be machined and finished throughout their length so that the TIR is not more than 25 pm (0.001 in.). [Pg.25]

Mechanical seals and glands for all pnmps, except vertically suspended pumps shipped without drivers moimted, shall be installed in the pnmp before shipment and shall be clean and ready for initial service. On pnmps whose seals reqnire final adjustment or installation in the field, the vendor shall attach a metal tag warning of this reqnirement. [Pg.31]

For vertically suspended pumps with shafts exposed to liquid and running in bushings, the shaft shall be 12 percent chrome, except for Classes S-9, A7, A-8, and D- 1. Cantilever (Type VS5) pumps may utihze AlSl 4140 where the service liquid will allow. [Pg.131]

Double-casing diffuser vertically-suspended pumps shall be designated pump type VS6. [Pg.27]

Unless otherwise specified, the datum elevation shall be the shaft centreline for horizontal pumps, the suction nozzle centreline for vertical in-line pumps, and the top of the foundation for vertically-suspended pumps. [Pg.29]

Bearing housings for vertically-suspended pumps need not be arranged so that bearings can be replaced without disturbing pump drives or mountings. [Pg.92]

The requirement for fully enclosed impellers (5.6.1) does not apply to vertical suspended pumps. [Pg.92]
