The subway pump for mtr sewage lift is a key facility in the subway transportation system. Its main function is to collect the sewage generated in the subway station and effectively lift it to an appropriate height through a lifting pump so that it can enter the sewage treatment system, ensuring that the subway Cleanliness and sanitation of the station environment.

Performance parameters

Ambient temperature: 0°C~40C
Sewage temperature: 0C~40 (can transport 60C liquid in a short time)
Maximum density of sewage: 1600kg/m³
Sewage PH value: 6~9
Flow range:0~50m³/h
Lift range: 0~50m
Single pump power range: 4~15KW
Control cabinet protection level: IP55
Maximum number of starts of water pump: 20 times/hour
Features

● Sealed, no smell, environmentally friendly and hygienic
● Compact structure, saving space
● Quick and easy installation
● The water collection tank interface and the pipeline are flexibly connected with rubber hoses, which can reduce noise and vibration to a limited extent.
● Soft seal gate valves are installed at the inlet and outlet of the subway pump to facilitate maintenance.
● By installing a manual diaphragm pump (optional), the sewage in the water collecting tank can be manually drained when the electric pump fails or is repaired.
● Dual pump configuration, mutual backup; if the sewage inflow exceeds the flow range of a single pump, the other one can be put into operation as a supplementary pump.
● The liquid level sensor adopts air pressure + alarm float, ultrasonic liquid level meter + alarm float or float control methods.
● The subway pump adopts an innovatively designed dry spiral cutting pump, which greatly improves the passage capacity of dirt, is non-blocking and is easy to maintain.
● The water pump can be selected as a horizontal pump or a vertical pump according to needs.
● You can also choose a cyclone pump, which is suitable for situations where there are too many solid objects.
● Use a motor that can withstand frequent starting current shocks, with a protection level of IP68, and can still operate normally even when completely submerged.
● Uniquely designed cooling structure ensures efficient heat dissipation of the motor.
● Automatic flushing function to prevent sedimentation and blockage, water outlet diameter DN80 (variable diameter).
● The standard cable length between the controller and the water pump/control line is 10 meters (the cable length can be customized).
