CVP basic overview Electric motor
Gearbox Discharge pipe Pull out unit Concrete volute Concrete suction bell Formed suction intake
Design
Design features Pull-out unit Short, sturdy shaft Non clog impeller Easy inspection True pull-out design No intermediate shaft or bearing All bearings are anti-friction Maintenance free shaft seal
Design
Design features Pre-fabricated elements Simplified site installation No shuttering on site for pump volute and suction bell Reduced site installation time Guaranteed pump performance One civil contractor on site Formed suction intake with simple straight side walls
Comparison
VCT and CVP Vertical Circulator Deeper civil dig Higher speed Higher NPSHr Minimum submerge requirement
Pull out design is a considerable price adder Vibrations due to large motor support and long pump design
Concrete volute pump Minimum civil dig due to formed suction intake and civil integration Easy accessible for maintenance True pull out design Limited bearing span Concrete volute & Sturdy driver support eliminates vibrations issues
Comparison
VCT and CVP Vertical Circulator
Concrete volute pump
Maintenance interval 20.000 hrs
Maintenance interval 50.000 hrs
Spare part inventory required
No spare part inventory
High alloy steels in corrosive applications
Corrosion free concrete is main construction material Highest availability and reliability Responsibility from suction to discharge
Comparison
VCT and CVP The surface area of the pump component in contact with water will have direct consequences for the pump price and maintenance High alloy steel materials are much more expensive than concrete materials
red = wetted parts of the pump
Comparison
VCT and CVP Difference in building volume 30% (m3)
At similar pump impeller size (1300 mm)
CVP have 50% reduction on crane capacity compared to VCT
Difference in digging volume 30% (m3)
Comparison
VCT and CVP
Concrete Volute Pumps
Comparison
Concrete Volute Pumps versus Vertical Metal pump
Summary, Cost Comparison Concrete Volute pump versus Vertical metal pump Limited suction pit depth Limited building height Limited Crane capacity for pump Reduced installation time if prefabricated concrete elements are applied High efficiency (up to 2%) Virtual no spares Very low maintenance cost Longer life time (many exceed 50 years service life) Only a few metal parts in contact with water, so minimum corrosion / erosion
Comparison
Cast on site and Pre-fab Concrete Cast on site by wooden shuttering Engineering, production, on-site placement and responsibility of: Shuttering Embedded parts Reinforcement Pouring of Concrete
Concrete curing time Shuttering removal
Prefabricated Elements Off- site prefab production Single day prefab installation No interference with job site schedule Single Flowserve responsibility, limited interfaces Embedded parts included and aligned Blast furnace slag cement Guaranteed quality and high accuracy shape & dimensions
Comparison
Cast on site and Pre-fab
56 days installation time
2 days installation time
Comparison
Cast in-situ and Pre-fab Simplified site installation (pre-fab) No shuttering on site for pump volute and suction bell Reduced site installation time Guaranteed pump performance One civil contractor on site Formed suction intake with simple straight side walls
