Fish Friendly Screw Pumps
The screw pump concept is over 2000 years old. Our partners FishFlow Innovations have revolutionised the concept by using the screw in an enclosed tube. With the enclosed screw design all the water that enters the pump is moved to the top, there is no leakage path as there is with rotating augers within a fixed trough/tube.
Friendly Fish Passage
Fish-friendly screw pumps have a specially designed impeller that allows fish to enter and exit the pump system without harm.
Environmental Conservation
By facilitating fish passage without injury, fish-friendly screw pumps help enhance aquatic biodiversity by contributing to the conservation of fish population.
Enhanced Pump Efficiency
When used in conjunction with variable speed drives, these pumps can operate at optimal efficiency, reducing energy consumption and ensuring low running speeds.
Reduced Noise, Vibration & Maintenance
The efficient design of fish friendly pumps reduces maintenance requirements, minimises noise and vibration during operation and results in lower maintenance costs and increased operational reliability.
About Fish Friendly Screw Pumps
One of the key design criteria of the pump was for fish friendliness. The fact that the auger is sealed within its rotating tube means there is no pinching or grinding surfaces where fish and eels can get trapped. The leading edge has a curved guide vane, which guides fish and debris into the screw pump minimising collision. The smooth entry into the water prevents risk of any blades strike and reduces turbulence in the water.
The entire pump can be delivered to site in a single module and installed in a matter of hours. When compared with a traditional screw pump the civil costs are also drastically reduced as a simplified civil structure is required.
Why Choose Fish Friendly Screw Pumps
01
Unrivaled Fish Friendliness
The Archimedean screw pump, developed by Fish Flow Innovations, prioritises the safe passage of fish through the pump system. A specifically designed leading edge reduces splash, turbulence, and direct strikes, ensuring the smooth entry of fish and preventing collisions. The pump also features a reverse facility that allows aquatic life to escape before the pump comes to a stop.
02
Simple Installation
Installation of Fish Friendly Screw Pumps is straightforward and time-efficient. Unlike traditional screw pumps that require complicated concrete half-pipes, these pumps only require a horizontal apron and a vertical wall for installation.
03
Simple Construction For Reduced Cost
The tubular construction of the fish pass allows for additional advantages, such as the ability to support longer lengths without sagging and pumping into a head of water. The increased efficiency of these pumps also allows for smaller overall station construction. Variable speed drives further optimise energy consumption, reducing the need for multiple pumps.
04
Customisable Specifications
Fish Friendly Screw Pumps can be tailored to meet the specific requirements of each application. By considering factors such as site conditions and desired flow rates, the pumps can be optimised for maximum effectiveness.

Frequently Asked Questions
The ACE Archimedes Screw Pumps have been designed to be fish friendly. When compared to conventional trough screw pumps they have numerous benefits. Firstly, due to the enclosed drum there is no leakage path. Meaning every drop that enters the pumps gets to the top. Secondly, the unique leading-edge design ensures fish are not struck upon entering the pump. Finally, there are no pinch points on the pump for fish to get caught in.
No, the ACE screw pumps are virtually maintenance free. Requiring only occasional greasing.
ACE screw pumps are more efficient than conventional trough type of pumps. With no leakage path there is no water slip that leads to inefficiencies. This means the pumps can be run at a lower more efficient speeds.
Yes. We consult to get the best solution for you requirements.

More About Screw Pumps
ACE and Fish Flow Innovations bring you the revolutionary Archimedean Screw Pump. With a history dating back over 2000 years, the Archimedean screw has found new life and purpose through the groundbreaking design of the Archimedean Screw Pump.
Traditionally, Archimedean screws faced challenges such as high wear levels, inefficiency due to leakage, and prohibitive construction costs. The screw pumps brought to you by ACE, has redefined the game by enclosing the screw in a tube, ensuring every drop that enters the screw is efficiently moved to the top, significantly improving overall efficiency.
The ACE Archimedean Screw Pump boasts a clever yet straightforward design, utilising high-grade materials like Stainless Steel and Vinyl Ester Composite to keep weight low, ensuring durability and a trouble-free lifespan. The absence of leak paths eliminates the need for seals that can wear down, guaranteeing that every drop that enters is efficiently pushed out at the top.
Installation is a simple with our single-module delivery, reducing site costs significantly compared to traditional screw pumps. The pump requires only a simple civil structure, minimising construction efforts and costs for surrounding buildings.
Developed in the Netherlands, the screw pump prioritises the safe passage of fish. The innovative leading edge, featuring a curved vane, ensures smooth entry into the water, reducing splash and turbulence while guiding fish and debris into the pump without collisions. An in-built reverse facility allows for the safe escape of aquatic life when the pump is stopped. ACE’s screw pump is not only efficient and fish-friendly but also incredibly easy to install. While typical screw pumps demand weeks of intricate construction, ACE’s only requires a horizontal apron and a vertical wall, with the unit supplied on a fabricated frame ready for installation. The advantages don’t stop there – our tubular construction offers further benefits, reducing the size of station construction. The pump has no length limitations, can pump into a head of water, and its increased efficiency allows for smaller overall constructions. Variable speed drives mean fewer pumps and minimal energy consumption. At ACE with our partner Fish Flow Innovations, we bring you unparalleled water movement solutions. Tailoring pump specifications to your site’s unique requirements, explore our recent projects or contact us to revolutionise your water movement solutions. Join us in embracing efficiency, cost-effectiveness, and environmental consciousness with the ACE Archimedean Screw Pump, the future of water movement.
