An Evolution in Fish-Safe Pumping

Providing Safe Passaging to Migratory Fish

Supporting the preservation of biodiversity in the face of significant ecological decline through innovative Fish-Safe pumping solutions.

We design and manufacture pumping systems tailored to specific site conditions and operational requirements, suitable for land drainage and flood control applications worldwide.

Our FS Range of Fish-Safe pumps are designed and rigorously tested in accordance with NEN 8775 standards. The range is configurable for global markets and is available with full compliance to UK Environment Agency MEICA Standards and Canadian Standards Association (CSA) requirements.

Rotodynamic Pumps

These pumps are ideally suited for installations where:

  • A minimal civil footprint is required.
  • Operation at remote, unmanned sites is necessary.
  • Tidal influences result in significant fluctuations in discharge rates or outlet water levels.

Fish-Safe Rotor-Pull-Out Pumps

Engineered for environments where health and safety are critical, delivering dependable performance where reliability is essential.

Fish-Safe Submersible Pumps

Canister-mounted units featuring high-integrity, low current density induction motors to ensure long-term reliability and service life. These pumps incorporate advanced cable protection systems and innovative lifting arrangements that eliminate the need for annual LOLER chain inspections.

Retrofit Solutions

Both our Rotor Pull-Out and Submersible Canister pumps are available as bespoke retrofit solutions, engineered to integrate seamlessly with existing civil works and mechanical interfaces.

Benefits of Innovative Fish-Safe Pull-Out-Pumps

  • No requirement for personnel to enter confined spaces to remove the pump after initial canister installation
  • Pull-Out options with no mechanical seal or packing gland, only a maintenance free controlled leakage device.
  • Surface mounted motor options with replenishable grease lubricated bearings offering 100,000 hours service life.
  • Retrofit solutions to match existing civil and mechanical infrastructure.

Characteristics of a Fish-Safe Pump

  • Restricts risk of dramatic pressure differentials & high rates of pressure change
  • Minimises shear forces caused by rapid flow acceleration or deceleration
  • Limits blade strikes by increasing blade thickness & limiting rotational speed
  • Reduces exposure to shearing between impellers & diffuser vanes
  • Minimises risk of pinching in gaps between rotating parts
