Purpose of : GRU ground pumps and power pumps on their basis 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-align : Baseline; Background: 0px 0px; Font-Size: 16px; ">.
GRU 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.
GRU soil pumps (with increased passage) are recommended for pumping with larger inclusions of solid particles.
Material of the details of the prototing part of the soil pumps of the GRU: depending on the brand of the pumping wheel pump, The pump housing (snail) are made from wear-resistant ICh28N2 or steel 50l , armids are made of wear -resistant alloy ICh28n2.
GRU densification, GRUI (soft water supply with flushing water. Span>
GRU ground pumps and electricity units on their basis are produced in the climatic performance During operation 4 according to GOST 15150-69.
GRU soil pumps and units on their basis correspond to the requirements provided for in 3631- 010-71868127-12.
