GKN 60 Hz

Construction

Submersible pumps with multi-channel impeller.

Characterised by good protection against clogging, large spherical passages,

good wear resistance, low mechanical action on the fluid and high hydraulic

efficiency at high flow rates.

Low vibrations thanks to the dynamically balanced impeller.

Delivery port DN 200-250-300-350.

Applications

Motor

Induction motor 4-6 and 8 poles, 60Hz

460/795V ± 10%

Isolation class: H

Degree of protection: IP 68

Max number of starts per hour:

- 20 up to 5 kW

- 15 up to 10 kW

Cable: length 10m

- 10 for higher powers

Direction of rotation: clockwise top view

Motor suitable for operation with frequency converter.

For the movement of sewage and sewage grates.

Particularly suitable for the emptying of sewage from cesspits or primary

collection tanks or industrial waste water.

They replace single-channel pumps when a high solids passage diameter is not

required.

Solid passage from 100 to 164 mm.

Operating conditions

Liquid temperature: from 0°C to +40°C.

Maximum immersion depth: 20m (with cable of suitable length).

Maximum working pressure: 80 m.w.c.

pH of the liquid to be lifted: 4 ÷ 10

Continuous service (with water at minimum immersion level).
