A vacuum pump is a mechanical equipment that produces a partial vacuum to draw or pump out gas molecules from a sealed unit or chamber. A sealed pack has no air or gas remaining inside; hence, these pumps are used to create that perfectly sealed chamber or unit with a total absence of air inside. The sealed chamber may have liquids of varied consistencies from thin to viscous, semi-solids, pulps, slurries, and so on. Regardless of the consistency of the fluid inside, the pump must be able to function efficiently. Although this is an important requirement in all industries, this is applicable especially in the pulp & paper industry that deals with viscous pulps, semi-solids, and slurries. This post discusses the maintenance and troubleshooting tips for vacuum pumps used in pulp and paper industries. (more…)
Equipment and machinery for paper and pulp processing facilities can incur a significant capital investment, especially if purchased factory new. As a new player, this may be challenging; however, it is important. Hence, the demand for used and refurbished used equipment has surged over the last 15 years. This segment offers a great opportunity for Mills and managers who work on a short budget or are new to buying used equipment in good condition at affordable prices. This post discusses the significance of choosing to purchase used equipment for paper and pulp processing facilities and some pointers to consider when buying used equipment. (more…)
The paper and pulp industry has stringent and unique requirements for pumps. Durability and reliability are two important concerns for paper mill owners while choosing pumps. There are several manufacturers specializing in pumps for the paper and pulp industry; however, not all may serve your purpose. This post offers tips on selecting the right pump for the paper and pulp industry. (more…)
Valves in general help control the flow of fluids or gases at a required speed as well as preventing back flows. Knife gate valves (KGVs), as the term implies, are thinly shaped in design like a knife and the inner working “gate” within the valve cuts through the medium such as a chemical in liquid form or a slurry. These valves are prevalently used in the pulp and paper sector as they are useful in dealing with paper pulps and slurries. Knife gate valves are used in applications where liquids with dissolved solids, and particulate matter, are transferred from one point to another as part of continuous flow or intermittent dosing. This post discusses knife gate valves at length.
Magnetic flow meters or mag meters are devices used in industries to measure the flow of different liquids. They possess no moving parts and comprise a sensor and transmitter that measure the flow together. These devices are ideal for applications where any conductive or contaminated fluids may be present or for applications where low-pressure drops may be involved. Today, you can find magnetic flow meters from different brands; however, Rosemount Magnetic Flow Meters from Emerson have gained immense popularity in recent years. These flow meters are designed for aggressive high noise applications in paper and pulp and various process industries. This post analyzes the working, features, and applications of Rosemount flow meters.
High pumping efficiency and low operating costs are two important requirements across industry segments where highly toxic and contaminated liquids may need to be pumped. This requirement is easily met by Ahlstrom Sulzer Model APT and CPT pumps. These are end-suction, single-stage pumps exclusively designed for various demanding industrial applications. These pumps are used in pulp and paper, chemical, industrial water and effluent treatment, and many such industries where challenging working conditions exist. What makes these pumps different from other industrial chemical process pumps? What are the main applications of these pumps? Read this post to know the answers and more.
Process pumps are considered a big investment across industries. Many process outcomes entirely depend on the performance of these pumps, thus, they must be chosen wisely. Goulds Model 3196 Centrifugal Pumps are one of those process pumps that have gained immense popularity owing to their high-performance features. They are used in chemical, pulp and paper, petrochemical, food and beverage, and primary metal industries for different pumping applications. What makes these pumps popular? Why they have become the standard in the chemical process and pulp and paper industry? This post offers insights on four prominent features of Goulds Model 3196 Centrifugal Pumps that have contributed to their popularity.
Control valves are an integral part of process control loops and they are used to regulate various process variables such as liquid levels, temperature, flow, pressure, and so on. These variables need to be maintained in a certain operating range to ensure the quality as well as desired outcomes of the process. Owing to their increasing demand, today, it is quite common to find different brands in the market. Fisher® Control Valves are one of the most popular brand of control valves owned by Emerson. These control valves are known for their reliability and high performance, and have been widely used by process operators to maintain the quality of their products, meet production schedules, as well as improve the efficiency of their plant. Control valve noise reduction, digital isolation solutions, and anti-cavitation valve trims are a few advanced features that have contributed to the immense popularity of these valves. Are you intrigued to know about different Fisher Control Valves? If yes, this post discusses them in detail.
Positive displacement blowers or PD blowers are used to convey air or gas through a variety of industrial equipment across industries like pulp and paper, oil and gas, cement, power generation, and so on. Being driven by the principle of positive displacement, these blowers trap a fixed volume of gas or air and then force it against the pressure of the system. Owing to their increasing use across industries, today, you can find several positive displacement blowers in the market. The positive displacement blowers by Gardner Denver stand tall among them. The company provides different types of PD blowers including straight bi-lobe, straight tri-lobe, twisted tri-lobe, and helical screw blowers. As their name suggests, these blowers differ in terms of construction, design, and operation, and have specific functions. Among these, the straight bi-lobe blowers featuring two figure, rotatable eight lobes are quite popular.
The impact of the Covid-19 pandemic on humankind across the globe has been tremendous. This new strain of the coronavirus category was reported in China in December 2019, and has since become an international concern. Within no time, it spread across countries in Europe, Asia, America, and the Middle East. With lives at risk and much at stake, economies and businesses have been hampered terribly. There are many European and US-based businesses and factories in China, and this has hurt their economies badly as well. Supply chain and shipping deliveries have slowed down and even halted in some places.
