Land pumps type 350/40 and electrical units based on them are designed to pump highly abrasive hydroxyes with pH 6 ... 12, density up to 2200 kg/m3, temperature from 278 to 343 K (from 5 to 70 ° C), voluminous concentration solid inclusions up to 40%, the average size of solid particles 6 mm, maximum size of solid particles 12 mm, microstless up to 11000 MPa.
In the unit of the electric pump, the transmission of the torque from the electric motor to the soil pump can be carried out both through the elastic brown-folk coupling, and through cuneiform transmission.
The scope of soil pumps of the grati enrichment factories and metallurgical enterprises.
The structural scheme of the designation of the electrician unit during order, correspondence and technical documentation:
"Grait unit350/40/II-16-1.6-K", where
Grat - type of pump (double -hinged, with an internal body of wear -resistant alloy);
350 - feed in m3/h at a nominal frequency of rotation;
40 - pressure in m at a nominal speed of rotation;
II - support number number;
16 - a symbol of the reduced speed of rotation (nominal - the speed of rotation is not indicated);
1.6 - the maximum density of a hydros mixture pumped by the pump unit, reduced by 1000 times, kg/m3;
K - wedge -rephid transmission, in the absence of a designation of the type of transmission of torque, the unit is supplied with a connection through an elastic coupling.
