Submersible pumps (PN)

New Hydrosystems LLC sells submersible electric pumps designed for sewage disposal

Main scope of submersible pumps (PN):

  • housing and communal and industrial construction, agriculture, mining
  • sewage and industrial effluents disposal, arrangement of a drainage system on flooded pits and marshland

 Main advantages of submersible pumps (PN):                

  • Optimized hydraulic part
  • Robust construction, well-thought protection system
  • Durability

What is a submersible pump:

  • Small and lightweight unit for waste water disposal
  • Material design of housing parts: gray cast iron SCH20 (stainless steel version available on request)
  • Highly efficient unit with reliable construction and high efficiency

All about submersible pump hydraulics

It is impossible not to note the optimized PN’s hydraulic: two-channel impeller that provides:

  • high resistance to blockage
  • stability of operation without turbulent eddies

To talk about shaft protection, it can be noted that in the new PN there are 2-3 successively installed face seals made of wear-resistant materials. For the shaft safety, the seals are further cooled - there are tubes connected to it, through which the liquid and oil are pumped. Thus, shaft's reliable operation and durability is achieved.

Additional specifications of submersible pumps PN

  • Motor protection degree PN – IP68
  • Insulation class F
  • Presence of thermal protection prevents the PN's overload, as well as protection against moisture entering the winding (depending on the pump configuration and version)

PN are very unpretentious in installation and maintenance. It can be installed in pipelines through couplings or used as portable equipment

Environment parameters for the PN’s operation:

  • power supply not less than 50 Hz, three-phase to 380V/660V
  • temperature of pumped liquid up to 40°С, hydrogen index should vary within 4,0-10 pH, liquid density - not more than 1200 kg/m3 and mass fraction of solid mechanical impurities - up to 50%
  • minimum liquid level for pumping must be at least half of the pump housing

It should be understood that PN's are not capable to pumping the aggressive fluids and media containing a large percentage of solid, fibrous particles. Immersion depth of the unit must not exceed 7 meters.

Design features of submersible pumps

Well-designed construction of the impeller makes it possible to operate the unit without the possibility of its clogging. Fluid is pumped as quickly and efficiently as possible, operating characteristics is stable provided there are no vibrations and system overloads.

Bearing assemblies, as a rule, consist of 2-3 bearings (the number depends on the axial and radial load of the PN). This ensures the stability and long service life of the submersible pump.

PN's motor body consists of 3 basic elements: bed, covers and bearing shields. All connections between these elements have seals, but despite this, each PN after the assembly is additionally tested for leaks.

Cable and seals for cable in submersible pumps

  • Cable has a rubber sheath that protects it from an aggressive environment and promotes the ability to work at temperatures up to + 40°C
  • Between the motor and cable sheath there is a seal in the ring form, carefully compressed by a nut; Sealing bush, located at the point of cable entry into the motor cover, is made by vulcanization - this prevents the possibility of liquid infiltration into the motor

All about integrated motor protection systems

Built-in systems are completed exclusively on the Client's order!

  • oil-water sensor in the oil chamber - will warn if the liquid enters the oil (sends a signal to the control panel (CP)) - the signal may indicate a failure of the face seal on the pump side
  • humidity sensor (mounted in the bottom panel of the PN's motor) - able to detect the leakage of oil or mixture of water and oil in the 2-nd face seal; The sensor transmits a signal to the CP, automatically stops the pump
  • thermal protection sensor (mounted on the motor stator) - controls the temperature level of the motor windings and when critical digit is reached, stops the PN by sending a signal to the CP
  • external monitoring system - professional remote control is used, as well as protection of the electric driven pump
  • manual hoist - allows you to conveniently move the PN, without trying to transfer the unit by holding the cable (this is prohibited, as it may lead to loss of the electric driven pump tightness)

Requirements for the submersible pumps installation

Electric driven pumps PN can be mounted by rigid fastening to the pipeline, an automatic coupling with directing. It can also be used as portable electric driven pumps using flexible or rigid pipeline.
