An assembly for adjustably mounting a gear of a pump to a gear of a driver equipment includes a shroud member, and a hollow elongated stub-shaft. The stub-shaft includes a flange, and a hub member axially extending from the flange. The shroud member defines a first aperture whose diameter is greater than a diameter of the hub member. The hub member is received within the shroud member via the first aperture. The flange has a first set of holes to receive a first set of fasteners and releasably couple with the body of the pump. The flange also has a second set of holes that are configured to receive a second set of fasteners and releasably couple with the shroud member. A diameter of the second set of holes is greater than a diameter of the second set of fasteners.

1. An assembly for adjustably mounting a gear of a pump to a gear of a driver equipment, the assembly comprising: a shroud member defining a first aperture on a first sidewall, the first sidewall disposed proximal to a body of the pump;a hollow elongated stub-shaft including:a flange having a first
1. An assembly for adjustably mounting a gear of a pump to a gear of a driver equipment, the assembly comprising: a shroud member defining a first aperture on a first sidewall, the first sidewall disposed proximal to a body of the pump;a hollow elongated stub-shaft including:a flange having a first set of holes defined on a first side to receive a first set of fasteners and releasably couple the flange with the body of the pump, and a second set of holes extending therethrough, the second set of holes configured to receive a second set of fasteners to releasably couple with the shroud member, wherein a diameter of the second set of holes is greater than a diameter of the second set of fasteners;a hub member axially extending from the flange and received within the shroud member via the first aperture, the hub member disposed about a shaft of the pump to define an elongated annular space therebetween, wherein a diameter of the hub member is less than a diameter of the first aperture; anda stub-gear comprising a gear wheel and a collar which are integrally formed, wherein the collar is splined to the shaft of the pump. 2. The assembly of claim 1, wherein: the collar is disposed in the elongated annular space and is rotatably connected to the hub member, the collar further coupled to the shaft of the pump to rotate in unison with the shaft, wherein the collar is fastened to a thrust plate held in abutment with an end face of the hub member; andthe gear wheel is disposed at a free end of the collar and adapted to mesh with the gear of the driver equipment. 3. The assembly of claim 2, wherein the relative diameters of the second set of holes with the second set of fasteners and the relative diameter of the first aperture with the hub member is configured to allow an adjustment to the engagement between the gear wheel of the pump and the gear of the driver equipment. 4. The assembly of claim 3, wherein a position of the gear wheel relative to the gear of the driver equipment is adjustable in a plane parallel to the first sidewall. 5. The assembly of claim 1, wherein the diameter of the first aperture is in a range of about 1.01 to 1.4 times the diameter of the hub member. 6. The assembly of claim 1, wherein the shroud member defines a plurality of threaded receptacles located on the first sidewall and disposed about the first aperture. 7. The assembly of claim 6, wherein the plurality of threaded receptacles correspond to the second set of holes on the flange to receive the second set of fasteners for releasably coupling the flange of the stub-shaft to the shroud member. 8. The assembly of claim 7, wherein the second set of fasteners are hex-bolts having a bolt head and a shank axially extending therefrom, and wherein a diameter of the second set of holes is greater than a diameter of the shank received therein. 9. The assembly of claim 1, wherein the shroud member defines a second aperture on a second sidewall, the second sidewall spaced apart from the gear wheel and disposed in an opposing relation to the first sidewall. 10. The assembly of claim 9 further including a cover plate releasably coupled to the second sidewall, the cover plate configured to cover the second aperture. 11. The assembly of claim 1, wherein the flange defines an annular groove disposed about the hub-member, the groove configured to receive an O-ring to seal an interface between the flange and first sidewall of the shroud member. 12. An assembly for adjustably mounting a gear of a pump to a gear of a driver equipment, the pump having a shaft and a body configured to partially receive the shaft therein, the assembly comprising: a shroud member defining a first aperture on a first sidewall, the first sidewall disposed proximal to the body of the pump;a hollow elongated stub-shaft comprising:a flange releasably coupled to the first sidewall of the shroud member; anda hub member axially extending from the flange and received within the shroud member via the first aperture, the hub member disposed about the shaft to define an elongated annular space therebetween; anda stub-gear comprising:a collar disposed in the elongated annular space and rotatably connected to the hub member, the collar further coupled to the shaft of the pump to rotate in unison with the shaft, wherein the collar is fastened to a thrust plate held in abutment with an end face of the hub member; anda gear wheel disposed at a free end of the collar and adapted to mesh with the gear of the driver equipment, wherein a position of the gear wheel relative to the gear of the driver equipment is adjustable in a plane parallel to the first sidewall, wherein the gear wheel and the collar are integrally formed, and wherein the collar is splined to the shaft of the pump. 13. The assembly of claim 12, wherein a diameter of the first aperture is substantially greater than a diameter of the hub member. 14. The assembly of claim 13, wherein the diameter of the first aperture is in a range of about 1.01 to 1.4 times the diameter of the hub member. 15. The assembly of claim 12, wherein the flange includes a first set of holes defined on a first side thereof, the first set of holes are configured to receive a first set of fasteners and releasably couple the flange with the body of the pump. 16. The assembly of claim 12, wherein the flange includes a second set of holes extending therethrough, the second set of holes configured to receive a second set of fasteners to releasably couple with the shroud member. 17. The assembly of claim 16, wherein a diameter of the second set of holes is greater than a diameter of the second set of fasteners. 18. The assembly of claim 12, wherein the shroud member defines a second aperture on a second sidewall, the second sidewall disposed in an opposing relation to the first sidewall. 19. The assembly of claim 18 further including a cover plate releasably coupled to the second sidewall, the cover plate configured to cover the second aperture.
