The FSM Basket Screen meets the most demanding specifications

The FSM Basket Screen was developed to deal with particular problems associated with sewage pretreatment plant.
Parallel to the increasing demands of users, FSM introduced modifications to the basic design. These have resulted in an optimum product for the preliminary treatment of waste waterproviding high performance coupled with low operating costs.  The Basket screen is a coarse and fine screen and use for pump protection in waste water treatment.

Functional principle:
The basket screen for installation in sump shafts is based on the design of our grab bar screens.
The basket of the screen is raised and lowered in the shaft via an electric hoist. The basket is guided by two guide rails built into the shaft and four rollers fitted to the basket. The guides are curved above the operating Level, which allows an automatic emptying of the basket above the dumpster. Final emptying is carried out by hand with a rake. While emptying the basket at the top a coarse bar screen is closing the channel.

The drive is mounted on bracket on the crossbeam of the frame and consists of a wire rope drum with geared motor.  The hoist is provided with limit switches for the motor at the top and bottom positions of the basket – the end positions can be adjusted as desired.

The screen is manually controlled via a local control station with dead
man´s switch for raising and lowering the basket.

Features:

• High reliability through robust construction
• The screen allows the passage of grit without malfunctioning.
• Discharge of grease in large quantities presents no problem.
• Screenings conveyed positively to the discharge point.
• Reliable guiding of the basket in a trackway
• Excellent cost/performance ratio
• Low maintenance costs
• Suitable for outdoor sites / operation in winter
• Easily adapted to suit changed operating conditions
