Designing circuits to be safe

Whether it’s a recirculating aquaculture system (RAS), a hatchery or a research centre: SPECK supplies corrosion-resistant, all-plastic pump technology for aquaculture – gentle on fish, designed for continuous operation and with a clean design.

What your planning really needs

In aquaculture, the animals’ lives depend on technology. These four factors are crucial:

Corrosion-resistant materials
Salt water and continuous operation leave no room for rust. All-plastic construction holds up where stainless steel reaches its limits.
Fish-friendly extraction
Gentle, reliable circulation that does not cause stress to the animals.
Designed for continuous operation
Plants operate round the clock. Pumps that can keep up with that.
Advice on special cases
RAS, hatcheries or research: technical consultancy that understands the field of application.

Why planners use SPECK

All-plastic instead of stainless steel
A deliberate choice of plastic: corrosion-free, durable and low-maintenance.
Design using SPECK Select
A pump and operating point suited to your circulation parameters.
Experience from a wide range of aquatic environments
Swimming pools, industry, aquaculture: SPECK knows water in all its forms.
Advice on an equal footing
A direct line to specialists who understand aquaculture.

Frequently Asked Questions

FAQ

Frequently asked questions from planners

Aquaculture with SPECK: corrosion-resistant, gentle on fish, designed for continuous operation.

Why choose solid plastic rather than stainless steel?

All-plastic components are corrosion-free – even in salt water and under continuous operation. This extends their service life and reduces maintenance requirements compared with stainless steel solutions.

Are the pumps suitable for use with salt water?

Yes. We offer pump models specially designed for salt water. In addition to corrosion-resistant housing materials, we take into account suitable sealing materials and sealing concepts, as well as the other components that come into contact with the fluid. We tailor the design to the salinity and water chemistry of your system.

Are the pumps designed for continuous operation?

Yes. Our aquaculture range includes pumps designed for continuous operation. To ensure reliable water circulation, we select the appropriate series and model based on your operating conditions and the specific application. Accessibility for maintenance work should also be taken into account at the planning stage.

Do the pumps operate in a way that is gentle on the fish?

We design the system to ensure that water circulation is reliable and gentle – tailored to the rearing and stocking requirements.

What documentation will I receive to help me plan a RAS system?

Performance curves, dimensional drawings, technical data and operating instructions are available to assist with the pump design for your recirculation system. You can use SPECK Select to select and document suitable pumps. Our aquaculture team will assist you in interpreting the data for your recirculation parameters.

How do I plan for energy-efficient pump operation?

The basis is a pump whose flow rate and efficiency are suited to your system’s operating point. Where requirements vary, a suitable speed control system can adjust the output to meet demand. It is particularly worthwhile to compare the energy consumption of different design variants, especially where operating times are long.
