Purpose of : Grau ground pumps and electricity units based on them are intended for pumping high-abiding hydro-mixtures with 6 ... 12, density up to 1600 kg/m3, with a temperature of 278 to 343 K (from 5 ° C to 70 ° C), a volumetric concentration of solid inclusions up to 30%, The maximum size of solid particles is 250mm (for the Grau 2500/60 pump), Microstless up to 9000 MPa < Span Style = "Margin: 0px; Padding: 0PX; BORDER: 0PX; OUTLINE: 0PX; Vertical-alig N: Baseline; Background: 0px 0px; Font-Size: 16px; ">.
Grau primed soil pumps and electrical units based on them are used in any industry, where it is necessary to provide hydraulic transport of solid particles, causing intensive abrasive wear of the material contacting with them:
-
Mining and Mining and Metallurgical Enterprises,
-
Cement, enterprise for cement production,
-
diamond and gold mining,
-
Technological lines of crushing,
-
Enrichment of minerals, etc.
Grau ground pumps (with enlarged passing cross-section) are recommended for pumping with larger inclusion of solid particles.
Material of the details of the prototype sort of soil pumps of the colum: depending on the brand of the operating wheel pump, the operating wheel. The pump housing (snail) are made from wear-resistant ICh28N2 or steel 50l , armids are made of wear -resistant alloy ICh28n2.
