Sand casting open type deep well pump impeller,impellers for water pump specification
Adopt unique simple vane or double vane impeller structure, greatly improve the through capacity of the contamination, can effectively through the pump five times of pump diameter fiber material and about 50% of the solid particles.
Mixer mechanical seal using new hard decay resistance of tungsten carbide as material, at the same time will improve as the double end face seal, seal the indoor running in oil for a long time, can make the safe running more than 8000 hours continuously.
Pieces of whole compact structure, small volume, low noise, energy-saving effect is remarkable, maintenance is convenient, without having to build pump room, working while being submerged into water, and greatly reduce the project cost.
In pieces to the sealing oil pump chamber has a high precision anti-interference leakage detection sensor, and embedded in the stator winding temperature sensitive components, absolute protection of pump motor.
Mixer can equipped with automatic security control cabinet, according to the needs of the user of the pump leakage, leakage, overload and over temperature of absolute protection, improve the security and reliability of the product.
Float beginning may vary according to the required level, automatically control the start and stop of pump, without modes, use very convenient.
Pieces according to the user, can be fitted with double rail automatic coupling installation system, which brings very much convenience to installation and maintenance, people can not into the sump.
Pieces can be used within the scope of the total head, with no overload of motor.
