Flumen OPTI-TR 20 … 40

Mixer

• Low cleaning work by avoiding deposits during basin draining thanks to installation close to the ground
Low clogging rate and reliable operation thanks to optimised hydraulics
Low-wearing, due to the use of stainless steel precision-cast propellers with the lowest cavitation tendency
A wide range of possible uses in diverse applications, even at high-interval running times
High flexibility thanks to the most diverse installation options and accessories

Materials

Motor housing: ASTM A 351 or ASTM A48 Class 35/40B
Seal housing: ASTM A 351
Seal:
- On the motor side: SiC/SiC or nitrile

Propeller: ASTM A 351

Construction

Propeller

2- or 3-bladed propeller made of solid material with a nominal propeller diameter of 8 in to 16 in. Clogging-free propeller geometry design made possible by backward-curved incoming flow edge.

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 40 ft long as standard.

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.
