120m3/h 50m 55kw 75hp Waste Dewatering Sewage Submersible Pump
Dirty Water
Sewage submersible pump applications:
Submersible sewage pump is widely used in industry, agriculture,
mining, civil construction, municipal environmental protection and
other places, it is the ideal equipment for pumping mud, mortar,
domestic wastewater, sewage feces and urine, and containing short
fiber, paper, sand and other solid particles and rural drainage
irrigation river pond silt.
Submersible sewage pump types: It can be customized with 304/316/316L stainless steel type, high
temperature resistent type and cutting impeller type.
Sewage Submersible Pump Working Conditions
Proper medium: liquids with chemical property similar to pure water
should be non-corrosive. Solid size should be no larger than 30% of
the pump suction diameter. Fiber length should not be over 2.5
times of the pump suction diameter. When the medium density is more
than 1.05, the motor power should be increased accordingly to
prevent the motor from overload operation.

Sewage submersible pump installation instructions
1. Check whether pump fasteners are loosen and whether the pump
body runner is blocked by foreign matters before installation to
avoid damage of impeller and pump body in running.
2. Supporters for the outlet pipe should be installed separately so
that the weight will not be added to the pump so as to prevent it
from deformation. The pump base for both movable and fixed
installation must be leveled by a level. After the base is ready,
install the pump on the base and then use a level to check
horizontal and vertical situation between the pump and motor shaft.
Use the iron shim to change the height of the base if the pump is
out of level. Then grout the base and anchor bolt holes by pouring
the concrete into the grout hole.
3. The levelness of the coupling device should be calibrated by a
level when coupling installation is adopted. Horizontal level
tolerance should not exceed 0.1mm/m. Use the measure gage to
calibrate parallelism of two coupling rods to ensure the
parallelism tolerance will not exceed 0.2mm/m.
4. Tighten the anchor bolt to make sure there is no looseness
between the anchor bolt and concrete in case of bad influence on
pump performance when starting.
5. For easy maintenance and safe use, install a regulating valve on
the outlet pipe and a pressure gauge near the outlet to guarantee
the normal operation within the rated performance range, which
lengthens the lifetime of pumps. Rotate the impeller from the
suction side after installation. Disassemble the pump and find out
the reasons if there is friction or stuck pump.
6. The pump installation can be divided into three types, movable
type, fixed type and coupling type.
