Double Suction (First Stage) Impeller features large passageways and produces balanced hydraulic thrust for a stable performance curve with low shut-off pressure.  The double-suction design on multistage pumps permits higher head and orating speed than vertical turbine models while maintaining excellent suction attributes.

Heavy Walled, Twin Volute Casing with robust transition diffuser moves liquid from casing to column through large waterways at low liquid velocity, minimizing corrosion, erosion and radial loads on bearings.

Suction Bells efficiently direct liquid into the impeller inlets with minimum resistance.

Bottom Liquid End Bearing is sealed for life with grease.

Optional Impeller Wear Rings enable restoration of original clearances for increased efficiency.

Operating Parameters

• Flows to 25 000 m³/h (110 000 gpm)
• Heads to 500 m (1640 ft)
• Pressures to 70 bar (1015 psi)
• Temperatures to 200°C (400°F)
• Column sizes to 1500 mm (48 in)

Flexible Design includes horizontal and vertical models, a variety of nozzle position options, and direct or independent motor mounting.

Minimal Shaft Deflection, with oversized shaft and reduced overhang, eliminates shaft failure, and increases packing and seal life.

Hardened Chrome Steel wear rings and shaft sleeve extend pump life.

Stuffing Box readily accommodates packing or mechanical seals, per customer preference.

Adjustable Wear Ring Clearance ensures continued efficient operation.

Hard Metal Casing made from abrasion and corrosion resistant high chrome iron incorporates integrally cast straightening vanes in the suction nozzle to reduce pipe swirl and extend impeller life.

Closed Impeller has pump-out vanes on front and rear shroud to reduce stuffing box pressure and suction recirculation, as well as to balance axial hydraulic loads.

Standard Packing Type Stuffing Box is protected by replaceable wear plate and is drilled and tapped for L5 and 2L3 lantern ring positions. Provided with full and low flow flush connections. Optional 316 SS, Alloy 20 or Alloy C-276 materials.

Cast Iron Lower Bearing Housing is fitted with a rubber or urethane fluted bearing, which is contained in a rigid stainless steel shell and lubricated from an external clear liquid source.

Features:

• Interchangeability of parts among R pump and M pump
• Concentric casing design
• Directly coupled or V-belt driven
• Options
  • Acid resistant stuffing box kits
  • Hard metal expeller
