Hydraulics

Discharge port with horizontal flange connection. Maximum dry solids content is 8 %. The impeller type used is a semi-open two-channel impeller.

T motor

Surface-cooled high efficiency submersible permanent magnet motor without cooling system for wet installation. The housing parts transmit the waste heat of the motor directly to the fluid. The motor itself is dry. Permanently lubricated rolling bearings are used for the motor bearings. The power cable is longitudinally watertight and has bare cable ends. Depending on the motor size and the motor power, the motors can be installed dry and operate in short-time duty.

FKT motor

Self-cooling high efficiency submersible permanent magnet motor with active cooling system for wet and dry installation. The cooling system is designed with a closed cooling circuit. The filled coolant is a mixture of water and glycol. An impeller driven by the motor shaft continuously circulates the coolant. The cooling system is unpressurised when cold. A built-in pressure relief valve limits the maximum operating pressure to 3 bar (43 psi). The cooling flange transmits the waste heat to the pumped fluid. Permanently lubricated roller bearings are used for the motor bearings. The power cable is longitudinally watertight and has bare cable ends.

Seal

Seals on the fluid side and the motor side are available in the designs shown below:

• Design G: Two independent mechanical seals
• Design K: Block seal cartridge with two independent mechanical seals

Operating fluids

All operating fluids are potentially biodegradable and environmentally safe:

• Medical grade white oil
• Water-glycol mixture (35 % glycol and 65 % water)

Wilo-EFC frequency converter

A Wilo-EFC frequency converter drives the high efficiency permanent magnet motor. After an approval by Wilo, other frequency converters can be used.

Motor efficiency classes (based on IEC 60034-30)

The motors meet the IE4 (Super Premium Efficiency) efficiency level.
