Operating Parameters
• Flows to 1400 m3/h (6160 US gpm)
• Heads to 250 m (820 ft)
• Temperatures from -40°C (-40°F) to 350°C (660°F)
• Pressures to 25 bar (365 psi)
• Speeds to 4700 rpm
API 610 Configuration
The Flowserve CPXV vertical sump pump is also available in an optional API 610 compliant model, specifically engineered for the hydrocarbon and petrochemical processing industries. Rectangular or circular soleplates are standard. A full ANSI 150/300 lb RF soleplate is optional.
Standards Compliance
The CPXV is CE marked and compliant with applicable European directives, such as ATEX.
Modular Construction ensures installation flexibility with a standard column length of 0.5 m (1.6 ft), which equates to a minimum sump depth of 0.7 m (2.3 ft)
Additional Column Lengths are provided up to a maximum of 10 m (32 ft) Heavy-Duty Thrust Bearings with
axial adjustment made at soleplate level
Recessed Impeller version is available for enhanced solids handling capability. Suction Strainer optional
Fully Jacketed version is available for molten sulfur applications.
VTP Vertical Turbine, Wet-Pit Pump

Product Lubrication utilizes open lineshaft construction allowing lineshaft bearings to be lubricated by pumped liquid
Enclosed Oil Lubrication isolates the lineshaft and bearings from the pumped liquid minimizing maintenance in abrasive services. Alternative lubricants such as clean water or grease can also be used with enclosed lineshaft construction
Rebowl Services
Flowserve can revitalize the performance of aged VTPs and reduce total operating costs. Whether for competitor or Flowserve pumps, upgrades will reduce power consumption, downtime and maintenance costs while extending the pump life.
