Pump Construction
Casing/impeller:cast iron,stainless steel,copper,bronze
Shaft:carbon steel 45#,stainless steel
Mechnical seal:graphite/silicon carbide/tungsten carbide
O-ring:EPDM/viton
Feature:
1, using a unique double channel non-clogging impeller structure, improve the sewage overcurrent and discharge capacity.2, automatic mixing device. Have strong stirring force, stir pool sink precipitate into suspended solids and inhale into impeller to discharge, achieve the dredging effect.3, cutting board divides base into two. Stir, mix and water are not interaction.4, double-end face mechanical seal, long-term in the oil chamber,ensure pump safe and reliable operation.5, vice impeller structure of the fluid dynamic seals, both auxiliary sealing function,to protect the mechanical seal. And also balance the axial force, extending bearing service life.6, Can be customized with water leakage detecting probe if the customer needs . When water leakage happens, the probe will make signal, control system implementation of protection on pump. Our company can equip with automatic safety protection and control cabinet.7, Motor stator uses class B and class F insulation,equipped with thermal protector, 2.2kW contains or below when the motor overload to heat,protector makes action in time, cut off power supply automatically, so that after cooling the motor automatically operates, in order to avoid overload burning the motor,take the pump and motor insulation protection
