Advantages of using internal gear pumps

Advantages of Using Vikings Cast Iron Gear Pump to Maximize your Productivity

Viking Pumps has been a leader, innovator and company since its founding in 1911. The internal gear pumps from Viking have been tested for various applications and have proven to deliver quality results.

Invented by Viking Pumps over 100 years ago, the internal gear pump continues to be the company’s best-known product.

With cutting-edge advanced engineering features, Viking is one of the most popular Internal Gear Pump manufacturers. They are ideal for handling corrosive, viscous, and shearing liquids under low to high flow, pressure, temperature, and temperature applications.

With the help of this technology, businesses can conduct their operations more efficiently and effectively. The internal gear pumps are available in various materials, such as Cast Iron, Ductile Iron, Carbon Steel, Stainless steel, Hast alloy etc.

How does a Viking internal gear pump work?

Viking Internal Gear Pumps are reliable, simple, and easy to maintain. This makes them ideal for handling thin liquids, fuel oil and solvents, as well as thick liquids such as chocolate, asphalt and adhesives.

The internal gear pump is a positive displacement rotary pump that moves fluid by rotating the pumping elements. There are two gears in the Viking internal gear pump – a drive gear called the rotor and a driven gear called the idler. 

The idler gear fits within the rotor and rotates along with it. The rotor is attached to the shaft, which is coupled with a driver (generally an electric motor) that drives the pump.

The gears unmesh at the suction side of the pump and create a vacuum, pulling the liquid into the pump. This liquid is carried to the discharge port. At the discharge port, the gears come into the mesh, causing high pressure and discharge of the liquid. The crucial aspect is that the pump does not develop any pressure during the entire process. 

It overcomes the back pressure and positively transfers the liquid from one end to another. The back pressure it can work against is directly proportional to the power it gets from the driver.

The internal gear design can handle various viscosities and provide unparalleled efficiency in numerous industrial applications. 

Because of its unique design, flexibility and easy maintenance, Viking is known as the leading cast iron gear pump manufacturer in India.

Cast iron gear pumps come with a range of additional features and advantages that are certain to improve the performance and concreteness of the work.

Common internal gear pump applications include, but are not limited to:

All varieties of refined fuels & lubricants

Resins & polymers

Alcohols & solvents

Asphalt, bitumen & pitch

Polyurethane foam (isocyanates, polyols & additives)

Food products such as corn syrup, chocolate & peanut butter

Paint, inks & pigments

Soaps & surfactants

Heat transfer fluids

Why choose a Viking internal gear pump?

Viking Pump was founded by Jens Nielsen, who invented the internal gear pumping principle. As described above, it uses two rotating gears which un-mesh at the pump’s suction side to create voids that allow atmospheric pressure to force fluid into the pump.

It offers the following:

The broadest selection of materials, designs, seals, ports and displacements

Different types of bitumen quality tests used in the road work

Construction of anything that can be road or any building involves a lot of planning behind it. To ensure that the construction work done of it will provide the best result, some tests are conducted to evaluate the consistency, temperature, gradation, and safety of the bitumen. For this different types of tests are conducted using different types of equipment like the penetration test of bitumen apparatus.

Some of the tests are stated below that evaluates the characteristics of the bituminous rocks.

Softening     point test: The softening point is when the bitumen is kept under certain     temperature conditions so that it can become very soft. For conducting     these tests, there is the requirement of ring and ball apparatus. The ring     keeps the bitumen sample in the glycerine and the ball is used to put the     sample into heat. In this, the temperature is recorded when the bitumen     reaches the point of being soft.

Flash     and Fire point test: It is very important to check the volatility of the     bitumen that is released at high temperatures. So it is very important to     make sure that the bitumen should not be overheated so that it catches     fire. The flashpoint test will help in evaluating the highest temperature     the bitumen can withstand without getting into adverse conditions.

Viscosity     test: It is the liquid characteristics of bituminous. This test measures     the resistance to flow and measures at what temperature the concrete mix     can provide the best results. So every time the concrete mixing is done     for the construction purpose the viscosity is observed to get the most     stable values.

Ductility     test: It is the characteristic of the bitumen that helps in undergoing     deformation. The ductility is measured in cm and to evaluate the standard     sample of the bitumen will be deformed without breaking it. To conduct     these tests, the bitumen sample is heated to a great extent and further,     it is poured into the mold and after this, the molds are kept in the cool     air. Even after this, the molds are given a water bath for cooling them     down. The value of the ductility can be influenced by the temperature at     the test and the rate of pulling.

Penetration     test: This is one of the tests that is conducted to check the hardness or     the softness of the bitumen. The standard bitumen extraction test     apparatus is used to conduct the test. The penetrometer is made     up of a needle that will weigh around 100 g. The bitumen is decreased to     the pouring consistency so that it can be emptied into the containers as     per the requirement. The penetration value can get affected if any error     in the pouring or the test temperature is done.

All these tests are done according to the need of the construction site. But it is for sure, it is very important to conduct them to have all the in-depth details that will help in taking the best decisions. These decisions can help in getting the best and the most desired results.

Various Tests on Bitumen to Assess Its Quality

Bitumen is a versatile substance with a dynamic pressure reaction. Both bitumens exhibit an isotropic nature that is more or less noticeable. Both the temperature and time at which pressure is implemented are reliant on their resilience to compression. A bitumen can act either as a standard elastic solid or as a viscous fluid only under severe circumstances. 

Both vicious and elastic behavior perform their function under regular temperature circumstances. Because under the situations of work, both temperature and processing time are adjustable. Bitumen temperature and time vulnerability are significant productivity variables. A variety of research techniques has been produced to classify the various bitumen categories. These experiments originally tried to quantify an abstract mechanical property that enabled it simple to distinguish between different bitumens. 

To determine the property of bituminous compounds, there are a variety of experiments conducted through bitumen testing instruments. Usually, the accompanying experiments are carried out to determine the various characteristics of bituminous compounds.  Penetration Test 

To assess the strength of bitumen, penetration tests are required by the assistance of testing equipment provided by bitumen testing equipment suppliers, so that they could be categorized into regular groups. Greater penetration value implies smoother quality. For usage in cold climates, higher density bitumen is usually desired and lower penetration bitumen is utilized in hot environment zones. By calculating the extent in tenths of a millimeter to which a regular packed needle penetrates deeply in 5 seconds, it tests the strength or smoothness of bitumen. It should be mentioned that the penetration level is mainly affected by any imprecision in terms of needle length, needle volume, and experiment temperature.  Ductility Test 

For a bitumen binding material, a sufficient minimal ductility is required. This is related to the temperature fluctuations in bituminous combinations and the frequent displacements linked to traffic pressures that happen in versatile roads. The materials that create tensile narrow films around the mixtures are of essential consideration. It will break the binder component that does not have adequate durability and thus offer the existing pavement layer. This, in essence, ends in detrimental effects on the foundation of the pavement. The durability is represented in centimeters as the distance to which a regular bitumen binder can be extended until the string splits. The test is utilized with the assistance of testing equipment provided by bitumen testing equipment suppliers to evaluate the bitumen's binding property and stretching capacity. Softening Point Test 

Bitumen is a corrosive stretchy element without melting points that are clearly described. As the temperature goes up, they progressively are becoming gentler and less corrosive. This is the factor for determining the softening position of the bitumen. The softening position is not a melting position; on implementation to heat treatment, bituminous material does not liquefy but instead rapidly changes from semi-solid particles to fluids. The softening point is reflective of the material's potential to stream at enhanced temperatures in operation. 

These are a number of tests performed to evaluate the reliability of bitumen. Bitumen is a quite significant element of many industrial estates, such as highways and roads. To maintain the consistency of bitumen, several tests are performed with the help of bitumen testing instruments.
