Product introduction
The motor and pump body of SD, SK, SP submersible electrical pump series are tightly coupled through the designed casing pipe shaft, and a suction filter is installed between the pump and the motor to effectively isolate the impurities in the liquid. The whole component is submerged in the liquid with the pump , which can prevent the cavitation of the pump . The centrifugal force generated by the motor rotating the impeller of the pump drives the fluid to push from the underground to the surface. pump mainly consists of ground components and underground components. The ground components include control cabinet, cable, transformer, etc., and the underground components include pipelines, pumps and other attached ground components, which extend to the bottom of the well through the transmission pipeline. The motor part of submersible electrical pump is usually installed under the hydraulic press. Three different materials are provided for selection according to different
working conditions
Pump operating conditions
Pumping liquids which are thin, clean, non-flammable, non-combustible or non-explosive liquids, not containing solid particles or fibers.
- Maximum ambient temperature: +40 °C
- Maximum altitude above sea level: 1000 m
- Maximum depth: 70m
- Enclosure class: IP68
- Insulation class: F
- Voltage: 3×220-240/380-415V
- 1×220-240V
- available with single-phase motors(0.37kW-2.2kW)
- Normal temperature pump: -15°C to +70°C
- Hot temperature pump: -15°C to +105°C
- The motors used for the measurements are based on 2900rpm or 2950 rom
- Tolerances to ISO 9906
- Measurements have been made with airless water at a temperature of 20 °C
- The curves apply to the following kinematic viscosity: = 1mm /s
- Select a best efficiency of the pump which is operating within the bold curve of the pump performance.
If the ambient temperature exceeds the 40 °C or the pump is installed at an altitude exceeding 1000 m, the
motor output power P2 will decrease. In such cases, it necessary to use a motor with a higher rated output.
