Chemical plastic pumps and abrasive-containing liquids

Manufacturers of pumping equipment for the chemical industry are increasingly giving preference to polymers when choosing materials for their products. This is due to their extreme resistance to aggressive chemicals and adaptability, and sometimes their relative cheapness relative to metals. Plastic pumps are much lighter than metal samples. At the same time, they have sufficient strength to work with engines up to 3000 rpm and significant performance. Currently, the main types of chemical pumps are centrifugal and diaphragm pumps. Modern centrifugal pumps are mainly pumps with a special mechanical seal and pumps with a magnetic coupling. Horizontal polymer chemical centrifugal pumps have high performance, are powered by a direct drive motor (Max. 3000 rpm), and are designed for fast pumping and/or pumping of aggressive liquids at a flow rate of 9 to 40 m3/h. If the impeller is open, the pump can pump even very polluted liquids containing small suspended dense particles in a continuous flow. Special chemically resistant mechanical seals make it possible to prevent the leakage of aggressive solutions of chemicals from the pump part and damage to the engine. They are made of polymers for use in standard conditions. For heavy – duty applications and heavily soiled liquids, use Teflon and friction pairs made of ceramic or silicon carbide. The Relative Strength of polymer materials made it possible to produce new types of pumps – plastic pumps with a magnetic coupling. Magnetic coupling centrifugal pumps are used in processes where aggressive reagents and solutions require circulation or pumping. The magnet on the motor shaft rotates the magnet integrated into the pump impeller with its magnetic field. Therefore, there is no need for shaft seals, since aggressive liquid does not come into contact with it. There is no need for expensive shaft material made of special resistant alloys. This significantly reduces operating costs Magnetic coupling pumps are designed for fast pumping and/or pumping of aggressive liquids at Flow rates from 15 to 1230 l/min (0.9 - 73.8 m3/h). Magnetic coupling pumps are used for pumping clean liquids with a viscosity of up to 200 cPs (at 20 °C). In general, plastics are not sufficiently resistant to liquids containing abrasive particles. Only a few of them are as abrasive-resistant as stainless and carbon steel. Relative bulk abrasive abrasion of various materials (PE-1000 - 100 abrasion) according to the abrasive wear test method in the abrasive mixture (ISO 15527). Therefore, only PVDF (polyvinyldene fluoride) and PE-100, PE-HD (polyethylene) can compete with metals in terms of abrasive resistance. A large amount of abrasives and solid particles in the liquid lead to rapid failure of plastic pumps with a magnetic coupling. Special pre-filters should be used to filter coarse particles. The coarse pre-filter is designed to install pneumatic or centrifugal pumps to protect them from suspended solids and foreign objects, without causing excessive loss of productivity. The basket filter is an important device for protecting the pump. Thanks to its use, suspended particles, filaments contained in the liquid are filtered. These elements are particularly harmful to pumps. The kit does not contain metal parts and is therefore ideal for highly aggressive substances such as acids and alkalis used in the chemical industry. The filter structure makes it easy to clean and inspect. Plastic diaphragm pumps are also suitable for abrasive-containing viscous liquids and liquids with dense particles. Special slurry (mud) pumps are better able to cope with these tasks. The flow part of the slurry pump is made of a high-chromium alloy or coated with wear-resistant rubber, which makes them suitable for liquids containing solid particles, as well as acids or alkalis, which makes it possible to use these pumps for a wide range of liquids. Centrifugal slurry pumps are used for pumping abrasive liquids with a high concentration of suspended particles. Pumps have different types of construction: horizontal self-priming, semi-submersible, submerged. In difficult operating conditions special rubber lined chemical pumps are used, as well as pumps with a working part made of thick-walled cast acid-resistant stainless steel AISI 316L .

Thermal oil pump for bitumen heating station

Long-term storage of the bitumen mass or the need to pour it from the bitumen storage into a tank truck means bringing the mixture into a liquid state, when the bitumen can be easily pumped over with a pump without harming the physicochemical properties of the building material. The most economical and rational way is the use of a heat carrier - thermal oil, capable of receiving and giving off a large amount of thermal energy. Thermal oil is pumped by a circulation pump at a temperature of 250 C The thermal oil heated to a high temperature circulates along the entire circuit of the heat exchanger, transferring part of the heat to the bitumen, thereby maintaining its density and viscosity at a certain level, regulated by the standards and regulations for storing bitumen mass. NKY Hot Oil Pump NDP Gear Pump The design feature of the pump for thermal oil is the removal of the bearing assembly and the seal in the cooling chamber. Our company offers pumps for thermal oil with subsequent maintenance and supply of spare parts. Mechanical seals and special bearings for the pump shaft. Our design engineers will help you choose a thermal oil pump for a bitumen heating station.

Acid pump

How to pump acid in production? Many technological processes in the food industry, mechanical engineering, pharmacy, chemical and light industries use acids in technological cycles. Dosing, pumping acids, storage, transportation of acids! All these cycles are associated with acid pumping by pumping equipment and acid pump. One example is the supply of acid to the yeast department of a distillery. When from warehouses you have to supply acid to the acid tank in the yeast preparation workshop - yeast wort. Effective for Acids H2SO4 sulfuric acid H2SO3 sulfurous acid HNO3 nitric acid H3PO4 phosphoric acid H2CO3 carbonic acid H2SiO3 silicic acid Other acids Interaction of acids with metals. As we can see from the previous example, for the interaction of acids with a metal, certain conditions must be met (in contrast to the reactions of acids with bases and basic oxides, which almost always take place). First, the metal must be sufficiently active (reactive) with respect to acids. For example, gold, silver, copper, mercury and some other metals with the release of hydrogen do not react with acids. Metals such as sodium, calcium, zinc - on the contrary - react very actively with the release of hydrogen gas and a large amount of heat. acid metal salt HCl + Hg = not formed 2 HCl 2 Na = 2 NaCl + H2¬ H2SO4 + Zn = ZnSO4 + H2¬ Our pumps pump various types of chemically active liquids, cavities, cracks and more
