Rodelta ACVP (Axial Concrete Volute Pump)

The ACVP is a pump with an axial impeller, which discharges into a specially designed elongated concrete volute. The fluid flow is optimally guided through this volute by means of a metal spiral, which is attached to the pull-out unit. This volute is relatively large. This has been chosen in order to keep the energy loss as low as possible and to minimize possible blockages of the pump. The use of concrete also contributes to a solid construction and a low noise level of the pump in addition to durability and maintenance friendly advantages.

Features: Axial Concrete Volute Pump

• Corrosion resistance concrete volute pump casing and few metal parts in contact with pump liquid reducing material cost in corrosive/erosive applications (e.g. seawater)
• Space saving construction (pit depth, hoisting length/building height) compared with vertical pumps
• Less vibration due to robust design with casing of concrete
• Low inspection and maintenance cost
• Fish-friendly design available
• All electrical, undervoltage parts set up above water level
• ACVP Pump design builds less deep than conventional axial flow pumps (VS3) therefore 30% digging costs can be saved. (Imagine what this means for rocky ground)
• ACVP designed with a low-maintenance vision in mind, especially for the underwater parts.
• Environmentally friendly design with regard to contamination by lubricants. No lubricant can get into surface water.
• Practically no clogging problems due to large volute passage
• Different motor drive versions possible
• The ACVP can also be executed as a turbine. In times of little water the pumps can deliver water. But in times of too much water the same pump can be used as turbine. This way you can recover energy costs during turbine operation.
• This product beneficially contributes the Sustainable Development Goals (SDG’s) compared to other similar pump executions.

Specifications:

• Delivery size up to 2500mm
• Capacity up to 150000m3/hr
• Head up to 11m
• Suitable for liquid Temperature: Up to 50ºC
• Sealing Arrangement: Packed gland

Applications:

• Flood control
• Drainage- or irrigation pumps

Constructional features:
Axial Concrete Volute Pump

Pumpcasing
The spiral shape volute pump casing and suction are made of pre-fabricated concrete material and supplied by the pump supplier.
It is also possible to pour the concrete volute and suction on site.

Impeller & shaft
The impeller is axial (propeller) type mounted to the pump shaft.

Thrust bearing assembly
The axial thrust bearing assembly provided with radial roller and ball or spherical thrust bearings.

Discharge metal part (optional)
The discharge metal part is optional and connecting the rectangular volute out to the round discharge piping.
