One unique type of pump Sepro offers are peristaltic pumps. These pumps are versatile, ecofriendly and have benefits which are useful for mineral processing and many other industries.
What are peristaltic pumps?
Peristalsis is the constriction and relaxation of a tube, which creates a wave-like movement that pushes the contents in the tube forward. This type of pump has a flexible tube fitted inside a circular casing. Rotor rollers or shoes then compress the tube inside the pump. This creates pressure which pushes fluid through the tube. As the rotor moves forward, the compressed section expands to its original volume, creating suction that draws in fresh slurry. This design prevents contamination of the pumping fluid as only the inside of the hose contacts the fluid.
These pumps are used by processing industries to pump a wide range of liquids and semi-liquid materials. Other styles of pumps require the fluids to move past the pumping system. This is one of the main reasons that peristaltic pumps are a very popular choice for processing industries.
Peristaltic pumps provide a simple, low maintenance alternative to other pumps which use seals, stuffing boxes or glands.
Benefits of the C-Series Peristaltic Pump
The C-Series of pumps have all the benefits of regular peristaltic pumps and more. With a large pump housing, they displace approximately twice the volume of competitors’ pumps. As a result, Sepro’s pumps can operate at slower speeds while still maintaining a high flow rate. Special features include the ability to handle abrasive, aggressive and contaminated fluids, pumping in both directions, and stainless-steel construction options for corrosive environments.
Peristaltic pumps are also an ecofriendly choice, as they can operate with 25% less water and 60% less electricity than a traditional centrifugal pump. That can save 1.1 million litres of water a year and a lot of power!
These pumps provide a low maintenance solution due to their seal-free design and low operating cost. From safely pumping organic waste to dosing chemicals in water treatment plants, they provide an accurate consistent flow without valves, which can corrode and become clogged. The pumps can also pump in reverse so no chemicals are left in the line. The hoses are robust and made to withstand even the harshest materials. Since there are no internal components, maintenance is easy, leaks are rare, and there is no chance of outside contamination.
Which Industries use peristaltic pumps?
They are widely used in mineral processing plants to safely transport corrosive, abrasive, and viscous materials. Some of the duties the pumps can handle include thickener underflow as well as reagent, flocculent and cyanide dosing and transfer.
Their accurate flow rates, robust hoses, seal-free designs, and low operating costs enable mineral processing operations to reliably pump materials like cyanide safely.
Chemical manufacturing plants often transfer corrosive, abrasive, and harmful compounds to mixing tanks and reactors. As there is no contact between the product and the casing, aggressive chemicals can be safely and effectively transferred by peristaltic pumps.
The pumps provide an accurate, metered flow without using valves which can plug and corrode. Their easily reversible action allows chemicals to be pumped back to the source, if necessary, so that no chemicals are left in the line.
With no mechanical seals to maintain and service and no product leakage, peristaltic pumps are a reliable alternative to conventional chemical pumps.
The fishing industry requires materials like whole or chopped fish, squid, offal, fish paste, carcasses and oils to be transferred without damage. This is sometimes carried out manually, using fork trucks and totes, which is a highly labour-intensive process. Using peristaltic pumps, large solids can be transported across the plant, eliminating the need for expensive equipment, conveyors, and manual labour. With hoses large enough for whole fish to fit through, the daily catch can be transported in a fast and cost-effective manner. This lowers labour costs while speeding up transportation, which is important for fresh products.
The construction and tunneling industries move large quantities of wet sand, drilling mud, slurries and other materials. Typically construction sites use human labour to shovel material into wheelbarrows, haul them out of the construction area using front end loaders, and then dump it. Using a properly designed sump and peristaltic pump, this process can be vastly simplified, saving time, money, and labour. This also frees up staff to focus on other important duties.
Waste and Water Treatment
From pumping organic waste to dosing chemicals in water treatment plants, peristaltic pumps provide an accurate flow without using valves, which can corrode and become clogged. If necessary, the pumps can function in reverse to bring chemicals back to the source so that no chemicals are left in the line.
They are also used in water treatment plant to transfer and dose chemicals. The pumps provide an accurate, metered flow without the use of valves. Where fluids contain solids or other debris, the gentle positive action of the pumps is extremely forgiving. Even large objects can pass through the pumps without damaging them.
What materials can be pumped?
The hoses are large enough that fish can fit through without being damaged in the process. It’s not just limited to fish either! Squid, fish paste, offal, oil, and other semi-solids can be pumped through our peristaltic pumps. Transporting fish in this way is both cost-effective and fast, so you can spend more time actually fishing.
Thick syrups like honey (and of course, maple syrup) can easily be pumped with a peristaltic pump. Food-grade hoses are available for all sizes of our pumps. Also, since the pumped material is contained inside the hose, it does not come in contact with any internal pump parts, which prevents contamination.
Sepro’s peristaltic pumps can be found in many organic waste treatments plants in British Columbia. Pumping organic waste can be tough on pumps—you can find absolutely anything in this rotting slurry! As the thick and chunky organic waste breaks down, CO2, methane, and other gases are released—and all gases get pumped too.
Sand processing plants have been using our peristaltic pumps with excellent results. In one installation, our pumps transported a high solid slurry of sand 1,200’ with a rise of 100’ in elevation!
Chemical and mineral processing industries can both use our pumps. Whether you’re transporting an acid or a base, chemical leaching agent or hydrochloric acid, we’ve got you covered with a wide range of robust hoses.
Sepro also offers a variety of replacement hoses. Hoses are available in materials including EPDM, hypalon, oil resistant, neoprene, nitrile, natural food-grade, and natural rubber suitable for most applications.
Where fluids contain solids or other debris, the gentle positive action of the pumps is extremely forgiving. Even large objects can pass through the pumps without damaging them.
This line of made-in-North America peristaltic hoses are 45% less expensive than other competitors. Tests have proven that they last as long or longer than the competitor’s options. This increases cost-savings for clients.
