Submersible Mixers

Characteristics:

Application

Mixing, Agitating, Dissolving, Sludge homogenisation, Storm water tanks, Suspension of sediments or swimming covers also in pump pits, Mixing of chemicals and high, viscosity liquids, Fish farming, Flow generation, Cooling basins.

Materials

Propeller (Stainless steel 1.4436) Motor- /Propeller shaft (Stainless steel 1.4104) Motor housing (Grey cast iron EN-GJL-250) Motor bearing cover (Grey cast iron EN-GJL-250) Bolts (Stainless steel) Elastomeres (Nitrile Rubber) Installation system (Stainless steel 1.4571) Mechanical seal on medium side (SiC / SiC) Mechanical seal on motor side (SiC / SiC) Upper Bearing (Deep Groove Ball Bearing) Lower Bearing (Double row angular ball bearing)

Motor

Electric motors, with 4-12 pole motor speed. Insulation class H, degree of protection IP 68.Thermal sensors embedded in the stator winding protect the motor from overheating. PTC sensors on request. With seal probe in oil chamber.

Seals

The shaft seal with two mechanical seals (back to back) made from corrosion-resistant SiC/SiC, combined with two additional radial shaft sealing rings, which run on the carbon coated propeller hub, guarantee Optimum protection against the ingress of media and solids.

Features

Compact design by direct drive for installation in buildings with small space available. Installation on the basin floor because of small propeller diameter possible. Other mounting options via system dependent lowering device in pump shafts and on basin walls. Standard and optional Monitoring equipment ensures operational safety.

Installation

Mounting system with drain device for individual positioning of the unit and adjustable.

Pumped Liquid

Max. medium temperature: 40 °C, short term up to 60 °C.

Shaft/Bearing

Robust, maintenance-free, permanently lubricated deep groove ball bearings/double row angular contact ball bearings.

Propeller

2-blade propeller, self-cleaning design, stainless steel
