Sewage Impeller Features And Benefits of Hydraulics

Channel models: Multi-Channel Impeller

Applicable conveying medium: 

For contaminated liquids containing sludges and solids which are non-gaseous and not containing fibres liable to twist or bunch.

- Screened sewage

- Mechanically treated sewage

- Industrial waste water

- Effluent from waste disposal sites

- Storm water

- Activated sludge

- Industrial effluent

Vane models: Open Vane Impeller Open single and multi-vane models

Applicable conveying medium:

This technology has been specially engineered to handle tough requirements, such as higher rag and solids content caused by the need to reduce water consumption.

- Screened sewage

- Industrial waste water

- Storm water

- Industrial effluent

Vortex models: Free-Flow Impeller

Applicable conveying medium:

For liquids containing long fibres, solid substances, coarse dirt as well as gas or air.

- Raw sewage

- Activated sludge

- Circulated and heated sludge

- Raw and digested sludge

- Mixed water

- Handling sewage in rural areas in small pumping stations.

- handling liquids containing gas or sand

N models: N-technology (Transformation of FLYGT technology) Screw Impeller

Applicable conveying medium: 

The N - Impellers have a  semi-open, screw flow design and combine features of both screw flow and centrifugal flow impellers.

- N- impellers are ideal forsewage containing solid substances, long fibres and coarse dirt.

- N- impellers have a large solids passage that makes them  ideal for handling sewage in large terminal,inlet, and effluent pumping stations.

Screw centrifugal models: Screw Centrifugal Impeller (Transformation of Hidrostal)

Applicable conveying medium: 

The open spiral large channel of the pump has the characteristics of high efficiency and no blockage. It is easier to transport large solid and  long  fiber materials, and the ability to pass through particle diameter is far superior to other impeller types of water pumps Non clogging and non overload spiral centrifugal impeller, capable of  rotating soft solids on its own to prevent long fibers and solids from being entangled by the blade edge when entering the suction port, causing blockage.

Screw centrifugal models: Screw Centrifugal Impeller (Transformation of Hidrostal)

Applicable conveying medium:

The screw-centrifugal pump  can go beyond the limits of classical centrifugal pumps, and even into the application area of positive displacement pumps. The shape of the inlet edge creates an "inducer effect", which makes a large negative suction head possible (or a highertransportation media temperature). A pronounced screw shape creates a displacement effect with high viscosities, which makes possible the handling of viscous liquids well into the displacement pump application range.

Screw centrifugal models: Screw Centrifugal Impeller (Transformation of Hidrostal)

Applicable conveying medium:

1. Delicate goods in breeding farms.

Beet, fruit, vegetables, fish in breeding farms.

2. Liquids containing solids with abrasive properties, Coarse solid suspension, Fibrous, knot-forming material.

- Cereal suspensions, crystals, flakes.

- Unscreened sewage, abattoir wastes.

- Textile suspensions and artificial fibres, such as nylon.

- Storm water containing dirt and sand.

Screw centrifugal models: Screw Centrifugal Impeller (Transformation of Hidrostal)

Applicable conveying medium:

3. Viscous, sludgy and gaseous liquids: Paint, glue, paper stock, sludge from sedimentation as well as gas-producing or flake-forming biological processes.

4. Strongly abrasive media: Liquids heavily contaminated with sand and gravel, as well as grinding  and milling wastes.

5.Activated sludge: Activated sludge without damaging biological bacteria, transport sludge with a solid content of up to 18%.
