functional description

Our Concrete Volute pump has a reinforced volute housing with an integrated intake suction bell. Depending on the pumped medium the rotating parts can be constructed in either bronze or stainless alloys. The local circumstances determine the way of construction:
• assembly with prefab reinforced concrete segments
• compose the whole construction by pouring the concrete directly at site

Both options can be integrated in the civil construction and therefor reduces installation costs.

Maintenance-friendly
Our concrete volute pump provides in a maintenance-friendly solution. Due to its natural robust and heavy construction,
vibration and flexibility in movement of the pump are restricted to the absolute minimum.

Configuration
To optimize the pump station layout several options can be used that minimize the footprint and increase overall efficiency of the pumping station. Examples of optimized footprint are lateral, diagonal or angular positioning of the pumps. Next to hydraulic optimization of the volute and impeller design the right driver combination can reduce an energy consumption reduction. Example of an high efficient driving solution is a low speed permanent magnet motor.

Applications
• flood relief
• irrigation
• drainage
• cooling water
• seawater intake
