The most common console pumps of the NVR type, which are pumping units for hot water (up to 105GD.S) and cold, with the exception of sea. By the type of execution, they are usually single -stage, horizontal, with one -sided fluid supply. The main qualities of these pumping units: long -term operation, high performance, reliability and high maintenance.
There are also volumetric pumps, these are usually piston, dosage, gierce, rotor, screw, membrane.
One of the separate groups of pumping equipment is vacuum pumps such as VVN, NVR, AVZ, DVN, etc. They are used to pump out from sealed air volumes, non-toxic, explosive gas-proof mixtures and vapors that are not aggressive to structural details of the pump and working liquids. The pumped out the environment should be previously cleaned of mechanical pollution and dust, as well as drip moisture. Vacuum type and electric pump unit on its basis, designed to create a vacuum when working in air or inert gases is insoluble
