DRIVER OPTIONS

The CUP-BB1 can be packaged with various types of drive equipment to suit the application’s needs.

Typical options include:

  • 2 and 4 pole electric motors (fixed or VFD)
  • Diesel/gas engine or turbine
  • Further drive train options are available in order to achieve the optimal running speed
  • API 677 or API 613 gearbox units
  • Fluid couplings (geared or variable speed)

COUPLINGS

  • Flexible element membrane couplings as standard for high torque drives (to API 671 when required)
  • Excellent angular, lateral and axial misalignment capability
  • Can be supplied with special tools for hydraulic fitting and removal of hubs

ADVANCED SEALING ARRANGEMENTS (TO API 682)

The CUP-BB1 pumps come with a range of single or multiple sealing arrangements used to suit various critical applications and pumped fluid properties.

Typically for non-sour service API 682 piping plans 11 and 31 utilise the process fluid as a flush within a single seal configuration.

For more robust solutions multiple seal arrangements are adopted.

The options here are varied but fall into two principal categories:

  • Unpressurised tandem arrangements where product recirculation is commonly used for the in board seal with the outboard seal using a buffer fluid, from an external supply, at lower pressure than the sea chamber. Thus forming a high integrity secondary containment. Typically API 682 piping plan 52.
  • Pressurised double arrangements ensure no process leakage of gases, unstable fluids, highly toxic, abrasive, corrosive, and viscous fluids. Outboard seal holds barrier fluid from an external supply at higher pressure than the seal chamber.
  • Both seals are lubricated by the barrier fluid. Typically API 682 secondary flush plans 53A/B/C, incorporating a variety of vessel-type reservoir sealant systems.

LUBRICATION SYSTEMS

  • Forced lubrication systems, for use with hydrodynamic bearings, are fully compliant with api 614 (iso 10438) chapter 2 (special purpose) or chapter 3 (general purpose) to suit customer needs
  • As standard lube systems are supplied on a separately mounted console but can be ‘dropped-in’ to the baseplate on client request
  • For anti-friction bearing arrangements self-contained lubrication arrangements are commonly used

BASEPLATE DESIGN

  • Baseplates are all welded fabrications constructed from high quality rolled steel sections to BS, ASTM or equivalent material specification
  • Designs are influenced by a number of factors, including; customer specifications, equipment set-up, and conditions prevailing at site
  • Rigid, robust designs to ensure optimum structural integrity and minimal vibration levels
