Causes of wear of the friction pairs of the mechanical seal of the feed pump of the boiler DKVR. As a result of the operation of the pressure increase pump of a steam boiler, a feed pump operating on the supply of deaerator water without a bypass, for de-airing the chamber of the mechanical seal installation. Reasons: when the water supply pressure from the deaerator, water increases at a temperature of 105 C, a vacuum occurs at the pump suction, which leads to boiling and the formation of micro-bubbles of steam, which, with the design feature of vertical centrifugal pumps, fall into the upper chamber of the pump, where the mechanical seal is installed. As a result, the mechanical seal also works "dry". An example of a photo of mechanical seal wear in a vertical centrifugal pump of the CR GRUNDFOS, WILO MVI, CALPEDA, DAB, SPERONI, CDLF type. The whole difference is in the brand, and not in the principle of operation and the device of the pump. We provide our customers with service and warranty support, post-warranty service and the supply of spare parts for pumps throughout the entire service life.

The BTS Engineering company offers decanter centrifuges for processing sunflower and rapeseed foots , which contains 25% of dry goods – it is a precipitate that is formed during the production of vegetable oil. The basis of the non-fat complex of sunflower foots are phospholipids, protein and mucous substances of the starting oil. Sunflower foots has a high nutritional and energy value, it is processed at a temperature of 30 70 C We propose to divide the foots obtained during production in order to obtain a dehydrated cake, feed and filtrate with a minimum content of suspended solids for further purification. The quality of the filtrate after the centrifuge based on the above input parameters: The solid content in the filtrate (separated oil) at the output is 0.5 - 0.3 % of DS Sunflower or rapeseed foots are secondary product that appears in the manufacture of unrefined sunflower or rapeseed oil. It is often used in chemical and feed mills. Fats are isolated from the foots, which are used in the production of drying oil. The product is rich in fats and proteins. Therefore, it is part of the feed that makes up the daily diet of animals and birds. This supplement has a positive effect on the reproductive function, strengthens the immune system, improves growth and quality

The working position of the elements of the set of the hose-drum sprinkler machine provides: the installation of a tractor-towed chassis with a hose wound on a drum at the hydrant of the pressure pipeline, which is connected to the pump the unwinding the hose by dragging it with a tractor and laying it on the irrigation site in the sprinkling zone. the installation of a platform trolley with a sprinkler at the end of the moistened irrigation zone. the connecting the sprinkler to the hose and connecting the hose to the hydrant of the irrigation system. the supply of irrigation water to the water supply hose and the inclusion of the sprinkler in operation (watering). as watering proceeds, the hose is automatically wound at a certain speed on a drum driven by a turbine hydraulic drive (under the pressure of water coming from a pump to a hydraulic turbine or by means of a separate winding mechanism driven by a tractor. under the force transmitted to the hose during its winding, the trolley with the sprinkler moves in the direction of the hydrant, thanks to which a strip of agricultural land is watered with a width of 30 to 90 meters and a length of up to 300 to 600 meters or more, depending on the model and size of the hose-drum set of the sprinkler machine. Judging by the technology of work on the irrigation site, the hose-drum sprinkler device, the hose-drum device of rain irrigation to varying degrees refers to sprinkler installations and sprinkler machines. Due to the lack of its own propulsion for moving from one irrigation site to another and the need to use a self-propelled mechanism separate from the device when installing the sprinkler in the initial working position, the sprinkler (rain irrigation) under consideration refers to sprinkler installations. And on the basis of the presence of its own means for moving the sprinkler on the irrigation site during the irrigation process, this sprinkler can be attributed to sprinkler machines. To date, a significant number of various domestic and imported designs and standard sizes of hose-drum sprinklers have been developed, some of which are discussed below. This circumstance determines the possibility of using synonymous use of terms in the subsequent presentation: "hose sprinkler", "hose drum sprinkler", "hose drum unit" and (or)"hose drum sprinkler machine".

Diaphragm pump for detergents, gel, liquid soap, the ability to pump viscous products with active substances. Suitable for pumping viscous liquids and adhesives. The pump is suitable for unloading and loading onto vehicles, as well as packing in euro cubic meters. Productivity of the DP series 15 to 20 m3 per hour. The ability to use in categorized rooms.

High-temperature cantilever pump ALLWEILER NTT - for pumping thermal oil, self-cooling. Pumps are used in particularly harsh conditions: asphalt production, mineral wool production, oil industry - processing of dark oil products, bitumen production, heating of bitumen tanks, paint and varnish industry, food industry, production of plastics, tires, rubber, roofing, etc. Accordingly, the mechanical seal must be as durable and reliable as possible. BTS seals fully meet these criteria, using Viton rubber (fluoroelastomer), solid carbon, antimony-impregnated / SSic, silicone carbide. Shaft seal U5A (item 433.02) - uncooled, maintenance free, unbalanced. In front of the mechanical seal there is a safety stuffing box with the next throttling zone. Even if the mechanical seal fails, these additional safety elements prevent fluid from leaking. It is guaranteed that any leakage heat escaping from the shaft seal is safely discharged through the LO leakage outlet and fully collected. Due to the special design of the integrated unit, the temperature is reduced to such an extent that proper functioning of the bearing and shaft seal is ensured.

Centrifugal pump FLOWSERVE WDX series - horizontal, multistage, with vane diffuser. WDX pumps are modular in design with identical stages. A variety of optimal characteristics and materials allow it to be used for a variety of purposes, such as boiler feed or reverse osmosis. Modifications of these pumps imply the use of both stuffing box packing and mechanical seals . General recommendations for the use of a mechanical seal in FLOWSERVE WDX pumps: Mechanical seals do not require adjustment. Slight initial leakage will stop when the packing has been burned in. During the assembly operation, special attention should be paid to cleanliness. Before pumping dirty liquids, it is recommended to run-in the mechanical seal with a clean liquid to protect the friction pairs. Routine maintenance consists of checking the tightness. it necessary to detect any small leak. Never run a mechanical seal dry, even for a short time!

The VARISCO 4"EL J4-250 motor pump is designed for pumping both pure liquid and solid particles. High resistance to abrasive liquids is achieved, among other things, thanks to a high-quality mechanical seal . Mechanical seals are used with external lubrication. The materials of the oil seal (mechanical seal) can be silicon carbide by silicon carbide or tungsten carbide. We can also offer a rotating part made of graphite for pumping petroleum products. The type of rubber parts is Viton or NBR. It is also possible to equip the pump with a double seal or a cartridge seal.
