Double suction split pumps SMH

Summary

Product identification

The Sulzer SMH/SMHv is an API 610 (ISO 13709) Type BB1 axially split single-stage pump. The SMHv is a vertical shaft version designed for confined spaces.

Main applications include:

• Oil & Gas markets
• Hydrocarbon Processing Industries (HPI)
• Pumping of flammable, toxic, or critical cooling liquids, often at elevated temperatures and pressures.

Operating limits

• Bowl sizes: 150 to 800 mm (6 to 32 in)
• Capacities: 150 to 10,000 m³/h (660 to 44,000 USgpm)
• Heads: 10 to 200 m (32 to 650 ft)
• Pressures: up to 25 bar (up to 362 psi)
• Temperatures: -10 to 120°C (15 to 250°F)

Mechanical / Hydraulic

The SMH is designed to meet the requirements of ISO 13709 (API 610) and incorporates years of operational experience.

Features and Benefits:

• Bearings:
  • Oil lubricated with constant level oilers
  • Angular contact BECBM thrust bearing with machined brass cages
  • 6000 series ball or roller radial
• Mechanical seal:
  • Generously dimensioned seal chamber for unrestricted seal flush flow
  • Cartridge type mechanical seals may be fitted
• Bearing housings:
  • Carbon steel housings
  • Constant level oilers maintain oil level
  • Inpro bearing isolators prevent ingress of contaminants
  • Pure mist lubrication is available on ball bearings
  • Fan cooling available
• Optimum hydraulic geometry:
  • Delivers ideal flow patterns with low velocities for high efficiency and quiet running
• Casing:
  • Axially split for ease of maintenance
  • Branches in the lower half only
  • Complete rotor may be inspected/replaced without disconnecting main pipework
• Double entry impeller:
  • Principal axial thrusts are inherently balanced
  • Optimum geometry provides high efficiency, low NPSH, and quiet running over a wide operating range
  • Balanced to ISO 1940-1 G2.5
• Wear parts:
  • Integral impeller wear surfaces standard
  • Replaceable impeller wear rings optional
  • Casing wear rings standard
  • Replaceable throat bushings control pressure in the seal chamber
• Shaft:
  • Stiff design for arduous service conditions
  • Replaceable protection sleeves within the main waterways
  • Taper or parallel fit couplings can be accommodated depending on pump size

Materials:

• Bowl: NACE, carbon steel, chrome steel, other material as required
• Impeller: NACE, carbon steel, chrome steel, other material as required
• Shaft: NACE, carbon steel, other material as required
• Can, column, discharge head: NACE, carbon steel, other material as required
