Wilo-Flumen OPTI-TR 22 … 40-1

Your advantages

• Low cleaning effort: due to installation close to the ground, deposits are prevented during emptying of basins
• Low clogging rate and reliable operation thanks to optimised hydraulics
• Low-wearing, due to the use of stainless steel investment-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

Construction

Fast running and compact submersible mixer, directly driven

Application

Description/construction

Propeller

2- or 3-bladed propeller with a nominal propeller diameter of 200 mm to 400 mm. Clogging-free design made possible by backward-curved incoming flow edge.

Motor

Submersible motor of the T-series (surface-cooled motor) with standard connection for an easy and efficient adaptation of the motor power. The motor heat is given off directly to the fluid via the housing. The winding is equipped with a temperature monitor. Large grooved ball bearings ensure long service life of the motor bearings.

Seal

Double shaft sealing with large-volume sealing chamber to collect leakage from the mechanical seal; available with external pencil electrode on request. A corrosion- and wear-resistant mechanical seal is used on the fluid side. The seal on the motor side depends on the type:

• TR 28-1: corrosion-resistant and wear-resistant mechanical seal
• TR 22, TR 30-1, TR 40-1: Rotary shaft seal

Cable

Longitudinally watertight connection cable for strong mechanical loads. The connection cable enters the motor housing through a water pressure-tight cable inlet with strain relief and bend protection.
