SKA pumps

pompa skaSelf-priming SKA pumps, vortex, ring, with a side ring channel and an open rotor are used to pump liquids in the corrosion resistance range of materials used in pump parts. Liquids of a temperature up to 110°C, density 1300 kg/m3, viscosity up to 150 mm2/s, contaminated with traces of solid firm particles of the size up to 0.5 mm can be pumped. Typical self-priming pump applications Self-priming vortex pumps are used to pump clean water from tanks and shallow dug wells, in which the water level is at the maximum depth of 7 m from the ground surface.
A basic advantage of a dug well with a self-priming pump is a low cost of such investment. Household water demand frequently fluctuates. Therefore, to ensure optimum self-priming pump operations, use of water system automates (pump + hydrophore tank + protection and control system). Protection and control systems protect a pump motor against short-circuit, phase failure, overload, supply asymmetry or dry work consequences.

Water supply for households
Self-priming pumps are also used in water supply systems providing water for houses and residential estates.

Irrigating systems
Self-priming pumps are used in irrigation systems for crops and green areas.

Main advantages of Hydrovacuum self-priming pumps:
• guaranteed many years of reliable work
• easy access to spare parts
• execution of individual requirements and product customisation to customer requirements
• continual technical supervision, and guarantee and post-guarantee technical servicing
• low purchase and operation costs
• long life cycle in difficult operating conditions.
