N Series Seal-less Armoured Pumps

Seal-less armoured pump with its own pump sump. This special design of a pump with its own pump sump is used wherever air inclusions in the medium prevail, foaming suspensions are pumped, or discontinuous inflow conditions occur.

Characteristics

Through the formation of a cyclone, gas bubbles are separated from the fluid mixture due to centrifugal forces and the solid-liquid mixture is pushed towards the tank wall, allowing the pumping fluid to be pumped evenly without gas blockages.

The inlet tanks can be designed in different materials, an inner coating e.g. rubber lining is also possible. The selection of materials and the geometry of the inlet tank will be adapted individually to the pumping medium and the operating conditions.

The N model series offeres several advantages at once:

  • Cantilever shaft, so that no shaft sealing is required
  • Tank volumes of up to 2.5 m³ can be manufactured for the pump sump
  • Version as a metallic or elastically lined pump is offered optionally
  • This seal-less, vertical pump has its own pump sump. The bearing and actuator are dry installed.
  • The inlet of the pump is placed from the shaft side, so that it discharges every flow up to the designed and calculated quantity (discontinuous inlet).
  • The pumping of gaseous and foaming suspensions is no problem.
  • The tilt of the tank is adapted to the type of transported solids.

We offer exclusively rectangular-shaped tanks.
