Filtration Units

Mobile oil filtration unit and pumping units such as AGF-15/AGF-25 Filtration unit is ideal solution for the quick filing of the hydraulic oil tanks, and for the hydraulic fluid filtration systems uses. They are used for the filtration of the contaminated oil. Our Heavy duty hydraulic filtration systems, oil cleaning equipments help to remove water from the oil systems and also decrease the contamination level. They allows also to monitor the fluid contamination and check it according to ISO standards.

Hydraulics Hose Assemblies

Hydraulics hose assemblies are majorly used in hydraulic drives and control systems and many machines. They are often used in equipment featuring mineral oils, water-oil emulsions, glycol water solutions, water.

Our flexible hose assemblies are made of rubber hose with one, two or four steel wire braids, with metal fittings undulated at the ends. These fittings are made of steel and plated with protective zinc layer, however can be made of stainless steel. Hydro is well known hydraulic hose assemblies’ manufacture, who can also crimp hydraulic hoses that will be useful for mining industry and is able to provide high pressure hydraulic hose assemblies up to 2000bars and many other special ones.
