New Gratt decanter centrifuges

Centri-Force is the appointed UK distributor of new Gratt decanter centrifuges and driers.


New Gratt Decanter Centrifuges

Centri-Force has been appointed by Gratt Industria de Maquinas as exclusive distributors of their product range in the UK and Ireland.  This is the first time that Gratt who now dominate the South American market have ventured into Europe and Centri-Force is delighted to have been selected as their partner for this important launch into Europe.

The Gratt Story

Gratt is a family owned manufacturer of industrial centrifuges founded in 1982 in Brazil.  Originally, the company was a producer of industrial centrifuges targetted at industrial processes in the South American market. Their success, based on quality, value for money and outstanding customer service has propelled them into a market leadership position with over 1300 decanter installations to their credit.

The attention to meeting customer needs caused the Company to expand its range to include high speed disc stack centrifuges, industrial driers, DAF Flotation units and a plethora of custom made products to keep their customers satisfied.As the business has grown the production methods have changed from primarily engineering led production to highly automated CNC controlled manufacturing methods, employing batch production and quality control that matches anything that can be found in the factories of the largest centrifuge manufacturers in Europe. 

The company is accredited to ISO9001:2008 by DNV making Gratt the largest manufacturer outside Western Europe to have a European audited quality control system. 

It is the combination of quality controlled manufacture, a passion for the business and relatively low labour rates and overhead costs compared to mainland Europe that make the entry of Gratt into the UK and Ireland such an exciting prospect.

The Products

Centri-Force is pleased to introduce the Gratt range of decanter centrifuges to the UK and Ireland.  Other products in the portfolio will follow.

The product range cover a wide range of sizes from a bowl diameter of 186mm to 620mm.  This covers most industrial applications and we will of course be happy to help size any machine for any particular duty. 

The materials of construction for the rotating assemblies are generally SS304 or SS316.  The foundry castings are centrifugally spun which spins any impurities in the metal to the outside of the casting which are then removed by machining / finishing.  This produces a casting with excellent strength to weight ratios, essential in the design of high speed rotating equipment.

The decanter centrifuges are available in two phase design, solid and liquid separation, and in three phase design, typically solid and liquid / liquid separation e.g. solid, oil and water.  The scroll differential is controlled by either a system of a gearbox and pulleys, or an electric motor back drive complete with inverter to provide variable speed control.  Variable differential speed control is typically used in processes where the solids and liquids contained in the feed presented to the centrifuge are subject to change.

The electrical process control panels are manufactured in the UK under Centri-Force supervision.  This means that we can support the panels during the life of the machine and there are no language issues with any software supplied.

Decanter centrifuges are manufactured to order from components which are batch manufactured on the company's CNC machines. This method of operation provides the ability to respond to customer requirements but also ensures that the lead time from order to delivery to a customer site is as good if not not better than any other European manufacturer.

All products come with a manufacturers warranty and Centri-Force stands behind the product to ensure excellent after care through the life of the machine.
