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.
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.

For high-temperature working conditions, the existing RMG12 will be replaced by the new eRMG12 with the introduction of eSic-Q7 instead of U3 tungsten carbide. In this case, the mechanical seals will also be 100% interchangeable, and the pump description will change to indicate the new material. This applies only to diameters 22, 28 and 38, while for 48 and 70 a balanced mechanical seal is the preferred solution. The description and article numbers do not change, except for the high-temperature version using the eRMG12 mechanical seal. The articles and description do not change, except for the high-temperature version with an eRMG12 mechanical seal. Seal face: carbon graphite antimony impregnated (A), carbon graphite resin (B), silicon carbide (Q1, eSiC-Q7) Seat: Silicon carbide (Q1, eSic-Q7), Tungsten carbide (U3) Elastomer: NBR( P), EPDM (E), FKM (V),HNBR (X4) Metal parts: CrNiMo steel (G), called Hastelloy® (m)

ALLWEILER pumps are above all reliability and quality! But no matter how correct the mechanism is, there are parts that need to be replaced or restored over time. Usually, rolling bearings, cuffs, and mechanical seals are replaced. Replacement of bearings is mandatory when a certain service life of the watch is running, regardless of their condition. The manufacturer describes the routine maintenance for service and warranty service. If the pumps operate in high temperature conditions, like hot oil pumps and with increased loads, then the service life of the bearings is reduced, so as not to cause their mechanical seal failure and workings on the pump shaft and housing.
An example of the use of mechanical seals of the mixer shaft, agitator when mixing and preparing milk in the production of cheese. What cheeses are produced: Altai, mountain, Carpathian, Kuban, Soviet, Swiss, Biysk cheeses. It is known that in the production of most of these types of cheese, the temperature of the second heating and mixing with a mixer or agitator , is used , which is in the range from +47°C to +58 °C. The process of mixing the product with the whey at different stages of maturation is very important for obtaining cheese, milk, whey as a product of high quality and sterility of the process. The process can be carried out both under heating and under vacuum or overpressure. The main reason for the failure of the mechanical seal is the wear of the friction pairs or the destruction of the friction surfaces of the seal due to the runout of the shaft or working in "dry" conditions. Replacement of the mechanical seal for the agitator-selection and consultation of the manager
