Ground pumps of GR are designed to pump highly abrasive hydroxyes with pH 6 ... 12, density up to 2200 kg/m3, with a temperature of 278 to 343 K (from 5 to 70 ° C) , the volumetric concentration of solid inclusions up to 40%, the average size of solid particles of 6 mm, the maximum size of solid particles 12 mm, micro -hardness up to 11000 MPa. The advantages of soil pump GR: - a single -body structure with 1.5-2 times increased by the thickness of the wall of the body of the spiral and armidist increases the resource, ensures the rapid replacement of parts of the prototype part and, as a result, the lesser downtime of the soil pump GR; - The running part of the soil pump GR is made of wear -resistant Cast iron Ichkh28N2 and is ideal for pumping highly abrasive environments.
