Description/construction

Propeller

2-bladed propeller with a nominal propeller diameter of 140 mm to 280 mm. Clogging-free construction thanks to backward-curved incoming flow edge and patented helix hub.

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. On the motor and fluid side, a corrosion- and wear-resistant mechanical seal made of solid silicon carbide material is used. A seal bushing ensures long-term corrosion-protected fit of the mechanical seal.

Cable

Longitudinally watertight connection cable type H07 for strong mechanical loads. The connection cable enters the motor housing through a water pressure-tight cable inlet with strain relief and bend protection.
