I.Brief Introduction
The submersible sewage sump pump is widely used for municipal engineering, building construction, hospitals, hotels, restaurants, industrial sewage, and sewage treatment industries, for conveying solid particles and long fiber wastewater, sewage, and rain, including raw water transport, aquaculture, and irrigation.
II.Use Range
1. Medium temperature does not exceed 40 ℃, the volume ratio of solid phase in the medium is less than 2%, medium PH = 4 ~ 10;
2. Minimum operating level: see installation dimensions (no motor cooling system), a motor cooling system, the water level as long as the pump to ensure normal water;
3. The main parts of the pump material for the cast iron or ductile iron, WQF series of stainless steel precision casting diving sewage pump, transport corrosive media;
4. The maximum particle diameter of the solid in the medium is smaller than the d50 value of the performance parameter, and the length of the fiber in the medium is smaller than the diameter of the pump outlet.
III.Parameters
Flow rate: 7~4000 m3/h
Head: 7~57m
Temp.: 0~+40℃
Power: 0.75~355KW
Material: Cast iron, Ductile cast iron, Stainless steel 304, stainless steel 316, stainless steel 316L, duplex stainless steel 2205
IV.Features
1. Impeller with the dual flow channel, matching the pump body, wide flow channel, dirt through the good;
2. Pump structure is compact, shaft extension is short, reducing vibration and noise, extends the machine seal and bearing life;
3. Cable is excellent for oil and mechanical properties of heavy-duty rubber flexible cable, can be in the ambient temperature of 40 ℃ long-term continuous work;
4. Watertight cable to prevent accidental leakage caused by the motor cavity into the water; pump-side cable properly fixed to prevent the motor cover cable pull-out device pull;
5. The leak detection device sends an alarm signal to the leakage inside the motor connection cavity, and the control system carries out protection to the pump;
6. Submersible pump dedicated high-performance squirrel cage induction motor, protection class IP68, B or F, H class insulation, each phase winding overheating, overcurrent protection components;
7. (1.5kW and below the pump without cooling system), the maximum degree of discharge of sewage; pump side of the tungsten carbide on the silicon carbide friction, high temperature, high temperature, low temperature, Impact resistance, wear resistance, motor side silicon carbide graphite friction pair, friction is small;
8. Set two sealed monitoring systems, any seal leakage can alarm;
9. Lifetime lubrication The maintenance-free rolling bearing can withstand all axial and radial forces and is completely separated from the pumping medium.
V. Installation method
Portable installation; Stationary installation.
