Our plastic chain scraper is a proven product that has been on the market for more many years. We offer you reliability and consistency with our well-engineered chain scrapers. A solid performing product where continuous development work is conducted to make the plastic chain scraper even better.
The motored gear is assembled on a vertically adjustable motor plate for tensioning of the power transmission chain. The transmission chain is made of acetal resin and is lubricated by the tank water. All moving parts are covered and protected by a light weight easy access aluminum hood.
The shaft is designed as a stainless steel tube with welded flanges. Plastic split sprockets are bolted to the flanges. The split sprockets enable maintenance without disassembly of the driveshaft. The drive shaft’s bearings are spherical long life heavy duty plastic bearings. The bearings are lubricated by the tank water. No additional greasing is needed.
Fiberglass reinforced plastic and the sigma shaped profile of the flights makes it more corrosion resistant, rigid, strong and flexible to resist high sludge loads without compromising the safe operation. Our flights are always available in stock in various configurations.
The unique sigma profile gives the scraper a natural high durability and rigidity which is incomparable with others. No additional reinforcing plates or additives are needed to establish that.
We define the suitable scraper profile based on tank dimensions and sludge load, and supply scrapers to tanks up to 33 ft wide in single configuration or 60 ft with twin configuration. We have a vast experience of specially designed configurations.
The scrapers are equipped with skids and filler blocks for the strongest possible fixation of the chain’s attachment link. A number of scrapers are equipped with rubber strips to sweep the entire tank floor
Plastic hubs with sprockets are fixed with collars on stationary solid stub end shafts. The shafts are secured in brackets that are welded to anchor bolted wall plates. Collector chain tensioning is available as an option.
Plastic skid strips on the tank floor and stainless steel wall rails guide and keep the scrapers in position. Our design makes the use of additional nylon wear strips on the wall rails unnecessary, which reduces maintenance costs.
The plastic collector chain type NCS 720S is made of an acetal resin which is a highly suitable plastic when it comes to chemical, corrosion and wear resistance and yet does not compromise on the strength or durability of the chain.
The chain pitch is 6” mm and the maximum break load is over 6,800 lbs. The chain is locked with simple snap-in pins.
Removal/installation is kept very simple with our special tool.
