The centrifugal soil pump 800/40 is a pump that, due to its constructive appenicities, is often installed on dredger. The horizontal soil pump 800/40 is 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 disposal of waste.
The GRU 800/40 pump works with a solid material of medium and high abrasiveness, a density of 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 a relatively rapid wear of the details of the flow of the pump
GRU 800/40, replacing them and repair costs. Also, when operating the GRU pump 800/40 with worn working wheels and armids, during operation, the efficiency is reduced and, as a result, the production characteristics of the GRU 800/40 are reduced and energy consumption increases. Partly, on the GRU 800/40 pump, these losses can be reduced by adjusting the position of the sealing ring. As the working wheel is worn out, the 800/40 GRU pump, the gap that appears is packed with a sealing ring. Also, due to the fact that, both on the spare parts of the GRU pump 800/40 and on the GRU pump 800/40, the price relatively (imported analogues) is low, then the complexity of the complexity and problems with the repair of the GRU pump 800/40, as in technical and commercially, do not arise.
Objectively, it is worth noting that the 800/40 pump pump in terms of technologies for reducing energy consumption and increasing energy efficiency of production by the leader is not. But during operation, the GRU pump 800/40 is able to largely satisfy the needs of consumers.
The wear -resistant alloy of the IHC28N2, from which the working wheel and armored car of the GRU pump 800/40 are made, has high hardness and is well resistant to wear. Type of sealing the GRU pump 800/40 - soft oil seal with flushing water.
Structural scheme for the designation of the electrician unit during order, correspondence and technical documentation:
"GRU USA 800/40", where
GRU - type of soil pump;
800 - nominal feed in m3/h;
40 - nominal pressure in m.
