Double suction pumps DHV and vacuum system in Kiev
Hydro-Vacuum S.A. with participation of TOV Hydro-Vacuum Ukraine, executed a significant pump delivery for the Ukrainian water mains in Kiev. In the third quarter of 2017 a pump station “ZHOVNIEVA" was started up for "Kievvodokanał" (www.vodokanal.kiev.ua). Two double suction pumps type DHV.150-605 PA with motors of 250 kW of power were installed there, with the output of Q=470m3 and elevation head of H=110 m.
The new pump house is aided with a vacuum system made by Hydro-Vacuum S.A. The vacuum installation - based on a vacuum pump type PW.1.12 - is intended for priming of the DHV pumps and suction pipes of the pumps. The tanks visible in the installation are used for:
- separating the vacuum pump with a rotary liquid ring from the primed centrifugal pumps, they protect the vacuum pump against priming with excessive amount of water - the tank on the suction side of the vacuum pump, the installation is provided with a water level detector, which monitors the safe liquid level in the tank.
- separation of the pumped gas from the vacuum pump working liquid - the tank on pressure pumping side of the vacuum pump.
A fully automated installation provided with an operation-control cabinet provides correct operation of the whole system of the new pump house.
Hydro-Vacuum S.A. has been present in the Ukrainian market for many years, i.a. by its “daughter” company Hydro-Vacuum Ukraine responsible for company operations not only in Ukraine but also in Russia, Kazakhstan and Georgia.
