Double Volute, Axially Split Casing Design minimizes hydraulic radial forces in any condition down to the minimum flow, thus reducing shaft deflection and increasing the life of bearings, seals and wear rings.

Suction and Discharge Nozzles are integrally cast in the lower half casing to permit pump disassembly without disturbing the piping. Nozzles are designed to handle external forces and moments equal to or in excess of ISO 13709/API 610 specifications.

Near Centerline Mounting provides superior pump alignment and performance at elevated temperatures.

Confined Gasket Design allows metal-to-metal contact for proper gasket compression and eliminates corrosion of bolts and nuts.

Raised Face Flanges meet ASME B16.5 standards and are available in Class 150 (PN 20) and 300 (PN 40).

Renewable Casing and Impeller Wear Rings are standard, permitting continued high-efficiency operation. Clearances are per ISO/API requirements

Double Suction Impeller provides hydraulic axial balance and allows minimal NPSHR. The complete rotor assembly is dynamically balanced to ensure vibration-free operation as per ISO/API requirements.

ISO 21049/API 682 Seal Chambers operate at suction pressure and allow for installation of cartridge-style single, dual unpressurized and dual pressurized mechanical seals to meet required safety and environmental requirements.

Operating Parameters

  • Flows to 15 000 m3/h (65 000 US gpm)
  • Heads to 250 m (820 ft)
  • Pressures to 25 bar (365 psi)
  • Temperatures to 150°C (300°F)
