Brackett Green Single Entry Cup Screens are recommended for installation on raw water intakes where low maintenance is a prime consideration. They ensure the effective removal of floating and suspended solids, thus protecting critical equipment such as pumps and heat exchangers.These screens, fitted with mesh ranging from 0.5mm to 10mm, can be installed as a single unit or as part of a two or three stage system.

Low Maintenance Costs
With each screen installed in a concrete chamber the initial capital cost of civil works may be higher than for a travelling band screen. However, this extra cost can normally be recouped within the first 3 to 4 years of operation, depending on site conditions, thanks to the cup screen’s extremely low maintenance requirements.

The main cooling water intakes of power stations, refineries and petro-chemical plants using fresh or sea water are among the applications for the Brackett Single Entry Cup Screen. It is also used at the intakes to water treatment and desalination plants.

Solid Shaft
The Brackett Single Entry Cup Screen is strongly built with a fabricated drum and a solid horizontal center shaft revolving slowly in heavy duty self-aligning ball or roller bearings. These are lubricated from deck-level reservoirs.

Water flows from the inside to the outside of the drum through mesh panels arranged around its periphery. These mesh panels are cleaned by backwashing at deck level.

The screen is driven by a drive unit positioned at deck level, with the final drive being by a nylon pinion which engages with a gear ring on the backplate of the screen. The drive gear and the main shaft assembly are the only moving parts.

Individually designed
Brackett Single Entry Cup Screens are designed to suit each individual application, with specific features as required to meet operating and site conditions.

Screens of this type may be up to 10 metres in diameter and up to 3 metres wide.

Ancillary Equipment
Brackett can supply all the plant necessary for a complete screening station.
