1. Design

Horizontal radially split volute casing pump in back pull-out design, to API 610, ISO 13709 (heavy-duty), type OH2, with radial impeller, single-entry, single-stage, centreline pump feet; with inducer, if required. ATEX-compliant version available.

2. Application

Refineries, petrochemical and chemical industries, power stations, offshore and onshore processes.

Flow rate (Q)	4800 m3/h
Head (H)	270 m
Fluid temperature (^oC)	450 °C
Pressure (bar)	110 bar

Low maintenance costs

The selection of a balancing system for the specific duty point markedly reduces axial forces and extends the bearing life.
The double volute (DN 80 and above) reduces the radial force and prevents shaft deflection. The load on bearings and mechanical seal is thus considerably reduced.

Long service life of the mechanical seal

Maximum permissible shaft diameter to API 610 minimises shaft deflection and vibrations.

Reduced operating costs
A choice of more than 70 hydraulic systems enables optimum pump selection to API for higher efficiencies.

High flexibility
The pump flanges are available for all common pipelines, meeting all standards up to PN100 / ASME Class 600

Long service life and high reliability of bearings

Heavy-duty 40° angular contact thrust bearings exceeding API requirements
Oil bath or oil mist lubrication

No cooling water circuit required

When fluid temperature and ambient temperature are high, the steel bearing bracket with integrated cooling fins and the optional fan impeller protect the unit from overheating.

Ease of maintenance

Mechanical seals to ISO 24109 / API 682 in cartridge design are easy to install/remove for maintenance
