DVMX API 610 BB3 Multi-Stage

Designed for processes engineers requiring reliable operation in the full range of high pressure services

The DVMX fully compliant API-610 11th Edition BB3 and ISO 13709 multi-stage process pump. Available in 4 – 14 stages. Horizontal axial split case running back to back impellers in heavy-duty double volute casings.

  • Flows to 2,640 gpm (600 m³/hr)
  • Heads to 4,260 ft (1,300 m)
  • Suction Pressure 232 psi (16 bar)
  • Temperature Range -40 to 410°F (-40 to 210°C)

Precision engineered API/ISO 13709 process pumps meeting rigorous engineering requirements for heavy duty, high temperature applications while receding the total life cycle cost and improving mean time between repairs. A perfect high-flow, high-head compliment to Sundyne low-flow, high-head integrally geared LMV and BMP centrifugal pumps.

Proven to be reliable, efficient and long-lasting, Marelli BB3 pumps provide a number of operational benefits for process engineers and plant operators:

  • API 610 11th Edition/ISO 13709 full compliance for reliability and accountability
  • Suitable with 60 Hz and 50 kW motors
  • Near-centerline mounted pump casing maintains alignment during operation at elevated temperatures
  • Opposed impeller design for balanced axial thrust for optimal seal and bearing life
  • Single suction closed impeller, with large suction eye for low NPSH requirements
  • Side-side nozzle arrangement. Nozzles are cast integrally with lower casing half for easy disassembly without disturbing auxiliary pipe work
  • Balancing line design for equalizing pressures in seal chambers for optimal seal life
  • Highly maintianable and easily replaceable wear rings to reduce overall life cycle costs
  • Ring oil lubrication system that incorporates a constant level oiler and sight glass
  • Dual volute for balancing radial thrust at each stage and for optimizing seal and bearing life
  • Cartridge type mechanical seals for easy assemble and proper installation
  • Dynamic flows analysis assures stable performance and high efficiency levels, with high mechanical reliability
  • Seal chamber in compliance with API 682 3rd Edition and ISO 21049, ready to accommodate single, tandem or double mechanical seals
  • Casings supplied under ASME B16.5 class 600, 900 and 1500
  • Cap nuts are arranged on the top half casing parting flange, allowing easy casing removal for rotor inspection and ease of maintenance
  • Extra large shaft diameter design to minimize deflection in operation
  • Choice of multiple impellers in each hydraulic pump casing for optimum efficiency over a wide operating range
  • A variety of instrumentation options are available for monitoring all key operating parameters (temperature, pressure, vibrations and more)
  • Socket welded, flanged drains and vents as standard (Gussets and bracing are available)
  • Labyrinth bearing seals, deflector, to avoid external contamination and maximizing seal and lubrication life
