KSMK API 610 BB2 Double Valute

Designed for processes engineers requiring reliable operation in heavy-duty elevated temperature process services

The Marelli model KSMK, API 610 BB2 and ISO 13709 radially split, centerline mounted, double volute, between-bearings centrifugal process pump. It is available in one or two stage configurations. These pumps feature a double suction impeller. In-line and side by side flange configurations are available.

  • Flows to 13,208 gpm (2,400 m³/hr)
  • Heads to 1,640 ft (350 m)
  • Suction Pressure 290 psi (20 bar)
  • Temperature Range -22 to 752°F (-30 to 400°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.

Proven to be reliable, efficient and long-lasting, Marelli BB2 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
  • Choice of multiple impellers in each hydraulic pump casing for maximum efficiency over a wide operating range
  • Centerline mounted pump casing maintains alignment during operation at elevated temperatures
  • Low suction specific speed and low NPSH characteristics, with a wide choice of impellers for optimum efficiency over a large operating range
  • Finned bearing housing to provide maximum heat dissipation under API 610 compliance
  • Deflection system with fins to improve cooling
  • Labyrinth bearing seals to avoid external contamination and maximize seal and lubrication life
  • Highly maintainable and replaceable wear rings to reduce overall life cycle costs
  • Mechanical seal chamber suitable for cartridges defined under API 682 3rd Edition
  • Socket welded flanged drains and vents as standard. Gussets and bracing also available
  • A variety of instrumentation options are available for monitoring all key operating parameters (temperature, pressure, vibrations and more)
