Pumping for Profit: Enhancing Efficiency in Fish Farms

Keeping water clean and healthy in an aquaculture facility requires careful disinfection, filtration, flushing, de-gassing and circulation. A reliable, energy-efficient pumping solution is key for this process.

Fisheries are busy places with little time for stopping a pump to disassemble it for re-greasing. The pumps for fish farms must have a long duty cycle.

Fish Farm Pump Systems

As global demand for fish grows and oceans are over-fished, it’s becoming more common to raise seafood in fish farms. These large facilities depend on pumps to transfer seawater, recirculate water to prevent stagnation and transfer waste.

Energy use is one of the main on-farm expenses in aquaculture, with pumping representing a significant portion of the total energy consumption. By selecting the correct pump size, operators can significantly reduce energy costs.

To calculate the required pump capacity, divide fish tank volume by the desired turnover rate (turnover per hour) to find the flow rate needed. Then choose a bao gia may bom chua chay ebara that can match that capacity. Fisheries are busy places, so there’s no time for lengthy service calls when pumps stop working – especially not when they’re circulating live fish.

Aquaculture Pump Efficiency

In aquaculture systems, pumps are essential for water transfer, nutrient distribution, and oxygenation. However, the amount of energy they consume is one of the most expensive operational costs.

The simplest way to improve your system’s efficiency is to make sure that the pump is properly sized for your application. Calculate the desired tank turnover rate and then divide it by your pump capacity to find out how many gallons per hour (or liters per hour) you need.

Pumping duration and power consumption can also be reduced by reducing the pump’s speed when less than full flow is required. Danfoss offers variable speed drives that allow you to adjust the pump motor speed electrically. This means that you can control your system flow precisely while saving energy on the “fifth fuel”. Energy efficiency is the key to lower operational costs.

Sustainable Pumping Solutions for Fish Farms

The aquaculture industry faces many challenges: salmon lice, water quality issues, algae problems and waste management. To mitigate these, fisheries rely on highly efficient and sustainable pumps to disinfect, filter, flush, de-gas, and circulate water.

Danfoss offers a range of pumps and power conversion technology for fish farms that improve pump efficiency by reducing energy consumption. For example, by applying Danfoss pump speed control, you can reduce fuel consumption in a recirculation system by up to 50%.

Fisheries are busy places where a lot is happening in the blink of an eye. There is no time for lengthy service calls, when live stock depends on continuous circulation of fresh water. That is why they need durable, easy-to-maintain pumps that require no lubrication. One solution is to use an air-injection pump.

Aquaculture Pump Maintenance

Energy costs are the second highest operational cost in most Florida aquaculture production systems. Improving pumping in aquaculture is one way to reduce these costs. The correct system sizing and installation of pumps can also improve performance, reliability and longevity.

Pumps should be engineered to operate at the best efficiency point (BEP). Operating outside of BEP causes cavitation and shortens the life of motors, shaft bearings and mechanical seals. This creates costly ongoing maintenance and operational expenses.

The topography of the farm site should be evaluated, as it influences water stability, drainage and erosion risks. This also affects the water quality parameters (temperature, salinity, pH and dissolved oxygen) required for specific species of fish to thrive. Having an extra pump on hand and plumbed into the system minimizes downtime in the event of a failure.

Innovative Pump Technologies for Aquaculture

In aquaculture, high water quality is critical for sustainable fish production. However, increasing fish population and crowded conditions can lead to poor water quality, stress and disease.

Airlift pumps with Constant Flow Technology help maintain consistent flow rates across changing conditions. This is particularly useful in RAS systems with media filters to keep waste from clogging the system and ensure oxygen gas supply at optimal levels.

DESMI offers a new range of high-flow, low-pressure pumps for RAS and flow-through applications on land. These are much easier to maintain and offer better energy efficiency over a wider capacity range than large propeller pumps. Integrated with an aquaculture-specific drive, they also support PLC control menus that are tailored to the needs of this demanding industry. Precision load measurement solutions are also crucial for aquaculture applications.
