Hose pumps, also called peristaltic pumps, are a great way to move a lot of liquids.
These pumps are strong enough to be used for both moving and dosing. And these positive displacement pumps have some advantages.
This post will further explain hose pumps for slurry and their uses for a slurry.
How Does a Slurry Hose Pump Work?
The pump has a hose that goes through the housing in a U shape. It has rollers on a rotor clamp that pump the hose to move liquid: The clamped point moves along the hose because the rotor moves.
So, the medium inside the pump moves from the intake side to the pressure side for positive displacement.
Hose pumps are sometimes also called peristaltic pumps or squeeze pumps. The word “peristaltic” comes from the Greek words “peri,” which means around, and “told,” which means to set in motion. It refers to the muscles of organs like the esophagus, which also move a medium by contracting.
Furthermore, the hose pumps can circulate slurry with a density of 1.6 to 1.8 and up to 80% solid content. The traditional centrifugal pump loses efficiency when it reaches 1.3 or 30% solids.
Because of this, slurry pumps use a lot of process water. For example, a plant that processes 75 tons of ore per hour at 65% solids can save over 1,100 million liters of water per year by replacing a process slurry pump with a hose pump.
Hose Pump Sizes and Uses
Hose pumps for slurry come in many sizes and different functions, from pure dosing pumps that can move 0.1 to 2,000 ml/min to feed pumps that can carry 10 to 10,000 l/h to large industrial pumps that can move up to 100,000 l/h.
High-quality hose pumps can handle up to 16 bars of pressure in their working parts. Peristaltic pumps can be used in many industries because they have flexible hoses and a wide range of capacities.
These things are:
- Food and pharmacies
- Chemical industry
- Mining Water and
- Wastewater
Hose pumps are commonly used in laboratories because they can transfer fluids without culture-changing their consistency or damaging cells. They are also used in the food industry for machine filling. They can work at frequencies as low as 1 Hz, which means that they can measure the smallest amounts at low pressure.
Types of Hose Pump and their Advantages
Hose pumps for slurry provide the following critical advantages to operators: High pressure is commonly capable of operating at up to 16 bars. Fill the casing with lubricant to protect the pump tube’s outside from damage and heating.
Because it takes much more force to stop the flow through a hose than through a tube, the hose pump needs bigger pumps and motors to get the same flow rate.
Many types of hose pumps are available, but the most popular is the dependable, long-lasting Verderflex line.
Several types of pumps are suitable for pumping slurries, as described below. However, critical issues need to be addressed before deciding which technology to use.
Size and type of solids in the liquid: The pump’s capacity and its parts will matter significantly in passing the solids in the liquid. Centrifugal pumps can be dangerous because the speed and shear inside the pump can damage the slurry or solids. Twin screw pumps generally cause minor damage to solids in a slurry.
Corrosivity of the liquid or slurry mixture: More corrosive Slurries will wear down pump parts faster and may affect the materials used to make the pump. pump
Which Pump is Suitable for a Slurry?
There is always a pump that is appropriate for heavy-duty applications. Below are the examples;
A peristaltic pump is one of the most adaptable types available. It is the ideal pump choice for many applications in many different industries because it can pump liquids with a wide range of other physical characteristics.
Peristaltic pumps have another significant advantage over other pumps: the process fluid is wholly contained within the pump’s hose.
This translates to more straightforward and less expensive pump maintenance because there are no mechanical seals or glands to replace, and the lack of any seal means the pump is safer.
This type of pump excels in applications where others face significant challenges. This pump can work well in any situation because it comes with hoses made of different materials and sizes. Although it is well known in the sludge and slurry removal community, its peristaltic action is ideal for applications requiring shear-sensitive material to be pumped with a gentle pumping action.
As to the maintenance aspect of the pump, it is very friendly and cheap, replacement hoses for peristaltic pumps are inexpensive and straightforward to replace.
Even though these are small things to think about, the cost savings that come from less downtime and lower maintenance costs can have a positive effect on the bottom line of the current economy. Such as
Hose improvement expands pump use.
Significant advancements in hose design and manufacturing have significantly increased their service life. New hose materials are now resistant to a wide range of harsh chemicals, organic solvents, oils, and fuels, and they work well in a wide range of temperatures and environments.
In addition to material advancements, the manufacturing process has been enhanced. The hose is the part that wears out because of how peristaltic pumps work. Hoses could suffer from accelerated wear in the past, partly due to how they were manufactured.
New ways of making hoses that make sure the walls are all the same thickness without any extra work have greatly increased their service life.
The traditional peristaltic pump
Peristaltic pumps are widely used in the mining industry, where process fluids with a high percent of solids and high specific gravity cause other pump technologies to fail.
They can handle the rough conditions and complex pumping jobs typical of the mining industry. Because the reagents are corrosive, diaphragm pumps lose their efficiency, which drives costs by using too many chemicals.
Positive displacement pumps, like progressive cavity pumps, have broken rotors and stators because they can run dry. Because of these harsh conditions and the benefits of peristaltic pumps, they are widely used in the mining industry.
The New peristaltic pump
The same benefits that led to the peristaltic pump’s success in the mining industry have led to new opportunities in sectors that have not traditionally used peristaltic pumps.
Peristaltic pumps have made inroads into the pulp and paper industry. A peristaltic pump can run dry and pump at meager rates. The pulp and paper industry cleans up wastewater that has a lot of fibers, chemicals, and fillers in it. When pumped at a low flow rate, this tends to clog pumps.
As a result, the efficiency of other pump types is jeopardized. The clog usually occurs on the suction side. The peristaltic pump can easily get around this problem because it can change the direction of flow by changing the way the rotor turns.
How to Choose a Hose for a Slurry
When choosing the best hose for your pump, you need to know a few different things about how it works. Even though the cost of a new hose might not seem like much compared to the total cost of the operation, when a hose breaks, it can stop the whole process and have a big effect on how fast things get done.
Choosing the proper hose from the start could make production faster because it won’t need as much maintenance.
Slurry hoses are a formidable replacement for rigid and heavy steel pipelines. They are simple to maneuver and install, often on-site using simple tools. Channels are great for moving things, but once they are set up, they are hard to use and don’t offer much flexibility.
Instead of pipelines, hoses offer the much-needed mobility that makes them perfect for tasks like dredging that require the pump to be moved often. The slurry hose can bend and easily fit into existing pipe structures without welding.
Slurry hoses also help to absorb system vibration, reducing wear on critical equipment.
- Noise and vibrations have been reduced.
- Makes up for heat and cold expansion.
- Capable of being installed on-site.
- Adaptable movement
Depending on the application, it is made of a variety of compounds.
Pumping slurries is a difficult task for those who have done it before. Slurries are bulky and challenging to pump. They cause excessive wear on pumps and their components and clog suction and discharge lines if they need to move more quickly.
