Advantages to you
Wilo-Flumen EXCEL-RZPE 30

Your advantages

  • Reliable continuous operation due to low clogging propellers and flow housing that is pump in non-clog design.
  • High operational reliability by using stainless steel investment-cast propellers
  • Reduction of energy costs thanks to high pump efficiency and standard IE3 motor
  • Customer-specific configuration taking into account the different pipe diameters and volume flows
  • Simple adaptation to the system parameters through operation with a frequency converter
  • Easy installation and removal, even when the basins are filled due to lowering devices and screwless coupling
  • Simple replacement due to adaptation to existing installations

Construction

Hydraulics

Propeller made of solid material with clogging-free propeller geometry. Pump in non-clog design flow housing with guide claw and two flange claws. The guide claw ensures smooth function when lifting and lowering the recirculation pump. The flange claws can be readjusted, ensure optimum centring on the discharge pipe and stabilise the recirculation pump at high operating pressure.

Alternative version with flange connection for direct screwing to the discharge pipe.

Motor

Surface-cooled submersible motor in three-phase current design with permanently lubricated und large-size rolling bearings. The motor winding is equipped with temperature monitoring. The motor heat is given off directly to the surrounding fluid via the motor housing. The connection cable is designed for heavy mechanical loads, sealed water pressure-tight against the fluid and is sealed longitudinally watertight. The connection cable has bare cable ends and is 33 ft long as standard.

The submersible motor meets the IE3 motor efficiency class (according to IEC 60034-30).

Seal

Large-volume sealing chamber with double shaft sealing. The sealing chamber is filled with white oil and absorbs the leakage from the seal on the fluid side. A corrosion- and wear-resistant mechanical seal is used on the fluid side. The seal on the motor side involves either a rotary shaft seal or a mechanical seal.
