The centrifugal soil pump Grau 1600/25 is a fairly common sizes of centrifugal soil pump in the hydromechanization industry. The horizontal soil pump Grau 1600/25 was designed specifically for use in such difficult operating conditions as the production of building materials and the production of construction work by a hydromechanized way, transportation and recycling of waste.
Grau 1600/25 pump operates with a solid material of medium and high abrasiveness, density up to 1600 kg/m3, a hydrogen indicator PH from 6 to 12, solid inclusions up to 85 mm and a temperature of +5 to +70 ° C.
Switching these materials is associated with relatively
The rapid wear of the details of the prototype part of the Grau pump 1600/25, their replacement and repair costs. Also, during the operation of the Grau 1600/25 pump, with worn working wheels and armids, during operation, the efficiency is reduced and, as a result, the technical characteristics are reduced at the Grau 1600/25 pump and energy consumption increases. However, due to the fact that, both on the spare parts of the Grau 1600/25 pump, and on the Grau 1600/25 pump itself, the price relatively (imported counterparts) is low, then the industrialists have complexity and repair problems, both in the technical and in the technical commercial terms, do not arise.
Objectively, it is worth noting that the Grau 1600/25 pump in terms of technologies for reducing energy consumption and increasing energy efficiency of production by a leader is not. But during operation, the Grau 1600/25 pump is able to largely satisfy consumer needs.
The wear -resistant alloy of the IHC28N2, from which the working wheel and armored carrier of the Grau 1600/25 pump is made, has high hardness and is well resistant to wear. Type of sealing the shaft of the Grau 1600/25 pump - soft oil seal with flushing water.
The structural scheme of the designation of the electrician unit during order, correspondence and technical documentation:
"Unit GRU 1600/25-1.6", where
Grau - type of soil pump;
1600 - nominal feed in m3/h;
25 - nominal pressure in m;
1.6 - the maximum density of a hydros mixture pumped by the pump unit, reduced by 1000 times, kg/m3;
