Pressure calculations and monitoring are crucial in recirculation systems to ensure efficient operation and troubleshooting of hot water systems.

Backflow means the undesirable reversal of flow of a liquid, gas, or suspended solid slurry into an unwanted area of the process; a slurry recirculation pump can be designed to keep this from happening. Points at which a slurry or suspended solids system connects with another system are called cross connections. Such connections occur commonly in home appliances such as clothes washers and dishwashers, but they must be carefully designed and installed to prevent backflow. A valve, such as a temperature-controlled check valve, plays a crucial role in preventing backflow in recirculation systems by managing water temperature and flow effectively. Another common location for a backflow preventer is the connection of a fire sprinkler system to a water main, to prevent pressurized water from flowing from the fire suppression system into the public water supply.

Depending on the type of mixture, railcar slurries may be need to constantly be agitated. This can be accomplished in a number of ways, but a superior method for some applications may The use of EDDY Pumps to recirculate slurry helps to move the material around enough to keep the solids suspended and keep from settling to the bottom of the tank. If the material is sufficiently agitated, the easier and faster it is to pump and transport to the next destination.

The pump can be mounted vertically or horizontally depending on the particular setup or project needs, however, if the pump requires an extended bearing house, it can only be mounted vertically due to the extended shaft.

Froth flotation used in mining is one of the most valuable ways of refining copper and other ores from low-grade materials. Not only is this separation method widely used in the mining and refining industries, but it’s also helpful in paper pulp manufacturing and fluctuation for wastewater treatment. Froth methods rely on both complete mixing of oil and acid additives that encourage particles to stick together and thorough agitation to generate plenty of turbulence. Slurry pumps installed in a recirculating position can provide both of these essential features without corroding due to exposure to the frothing additives.

EDDY Recirculation Slurry Pumps are specially designed pumps which are designed to accommodate a number of industrial industries not limited to mining, manufacturing, oil/gas drilling, and many more.

When it comes to selecting a valve, there is really no such thing as too much research. By doing all your homework before you begin reviewing manufacturing catalogues, you’ll have a better understanding of the scope and scale of the project and can more accurately estimate your costs.

(In residential applications, a dedicated recirculation loop is crucial in optimizing the performance of recirculation systems, ensuring hot water availability and efficiency, especially in homes with tankless water heaters. Modern homes often come built with a strong hot water recirculation system, avoiding the need for an inefficient water heater.)

A recirculation loop plays a crucial role in maintaining the mixture’s consistency in sump, railcar, and slurry tank mixing.

Froth floatation pumping is also used to maximize bitumen production. To maximize output from the plant and to decrease inefficiencies involved with pumping bitumen froth, many of the currently employed centrifugal pumps must be improved. Concepts of pumping may include degassing the froth while pumping it by special secondary impellers, or using inducers that centrifuge the heavier water and bitumen from the air. The air pockets may also be collapsed by recirculating a percentage of the slurry from the discharge back to the eye of the impeller, or by injecting hot water at the suction.

Often times, when storing sludge in large settling or digester tanks, the material in these tanks need to be constantly in suspension for any number of reasons. These can be accomplished by using a submersible EDDY Pump to keep re-circulating the slurry throughout the tank, keeping the sediment thoroughly mixed within the tank. Additionally, valves can be installed in the EDDY Pump recirculation system to release the slurry through a separate discharge hose once a material threshold is met. A check valve can help regulate water flow in the recirculation system, ensuring that only the necessary amount of slurry is pushed back into the tank, thus enhancing efficiency. This ensures that the entire process runs as smooth as possible keeping within regulatory standards for your industry.

The EDDY Pump’s open rotor design with high tolerances allow anything that will go into the intake to be passed through the discharge without issues. This allows the pump to pass more solids with less wear on critical pump parts which will lead to less maintenance, less downtime, and more profits.

Sludge is generated as a byproduct or required as a processing step in hundreds of different applications, from making livestock feed to dewatering construction sites. While settling tanks are commonly used to separate water from the suspended particulate that qualifies a mixture as sludge, eventually, that particulate needs to come out as well to empty these holding areas. Sludge mixing is also essential for the intermediary steps of wastewater treatment and feed production. Slurry pumps are a great choice for this sludge recirculation purpose since the open design of the cavity prevents clogging and internal wear, and keeps the pump running.

Liquid storage railcars and refrigerated cars allow for affordable shipping of essential bulk materials for food and medication production, not to mention dozens of different petroleum products and byproducts. Yet all of these mixtures tend to separate and thicken after days or weeks of travel, making it hard to nearly impossible to get the material back out of the tank. A recirculating pump is the ideal way to quickly and efficiently mix the materials back to the original viscosity and suspension levels. Delicate materials that can’t be heated excessively or exposed to too much air all work well with slurry pumps that offer a sealed system for mixing directly in a railcar or settling tank.

With various wastewater systems, it’s important to keep grit in suspension to allow it to be pumped further down the process line without settling at the bottom of any tank along the process. Recirculation pumps help this process by thoroughly mixing the solution containing grit, helping to prevent it from setting at the bottom of the tank which could cause issues if left unchecked. During the operation of recirculation systems, there can be instances where cold water temporarily flows from the tap before the hot water arrives.

All industrial pumps need to withstand tough conditions, but few pieces of equipment experience quite as much abrasion and vibration while operating as the slurry pump. Slurry pumps are designed to move the thickest mixtures and pass large pieces of debris without damage or wear on the pump, minimizing the demand for maintenance. This is why the EDDY Pumps are so useful for recirculation pump purposes. No matter the slurry recirculation purpose, there’s likely a good way to use a slurry pump to tackle the task. These seven applications are some of the most common slurry and sludge recirculation uses across the various manufacturing, processing, industrial sectors, and other high-solids pumping applications.

We live in a consumer-driven economy. Very few people purchase even a box of breakfast cereal without doing plenty of online research and pricing comparisons. Before you invest in anything for your home, you want to make sure the product is safe, fulfills your needs and, perhaps most importantly of all, you want to make sure you are getting a good value. Choosing control valves is really no different. At the end of the day, you want to ensure that you are selecting a product that is high quality, is economical and will get the job done for many years to come. The best place to start is by considering the most pertinent detail of any valve: the size.

The goal for any process control engineer is to find the smallest valve necessarily for the purpose. Often, the smallest valve is the least expensive. However, it is imperative that you know exactly the size needed for the pipe. Choosing the wrong size can lead to inefficiency and operating problems.

The best way to determine the right size for your needs is to use the Cv method.• First, find the minimum and maximum flows that the valve will experience. It is best to be as accurate as possible. A valve working below the minimum flow expectation will often hunt and fluctuate, which leads to pressure spikes downstream and, ultimately, a burst pipe.• Next, calculate the pressure differential between the lowest possible upstream pressure and downstream pressure required.• Input the minimum and maximum flows, as well as the pressure differential, into the following equation: • Q (gpm) = Cv x square root of pressure differential • Cv = Q/square root of pressure differential• Utilizing a manufacturer catalogue, choose a product with a Cv value that is at least the number calculated using the formula above. By choosing a valve with a slightly higher Cv than you have calculated, you have the flexibility for higher flows in the future.• Lastly, be sure the given flow rate is realistic and the pressures are accurate and proven. Always opt for exact calculations over educated estimates to ensure maximum efficiency.

These pumps respond to the demand for recirculation in various applications by detecting when recirculation is needed and activating accordingly, ensuring efficient operation.

Filters and traps added to a system to catch grit can only work on particles suspended in a steady flow of water. Introducing a slurry recirculating pump into the mix is a great way to stir up grit wherever it tends to settle. EDDY Pumps can withstand high levels of grit capture and pumping without excessive wear thanks to the ultra-recessed rotor and the power of the eddy current.
