Mr. Lowell Signor established SJS Machinery, Inc. after retiring from Centrico, Inc. (Westfalia Separators, Inc.) in 1976. Our business is the sales of used and reconditioned centrifuges along with quality spare parts and service.

In 1996 Lowell’s son, Steve Signor, became President and Manager of SJS
Machinery bringing his 19 plus years of experience from working as a Service Technician with Westfalia Separators from 1978 to 1996.

In 2000, Mr. Robert Santo was hired as Service Manager and Vice President. He bought with him five years of service experience as a Service Technician with Westfalia Separators from 1995 to 2000. Combined, we have many years experience in many different process applications where centrifuges are used.

In 2003, Clinton Signor was hired as a Servce Technician making him the third generation in the Centrifuge Business.

In 2006, Jason Acton was hired as a Service Technician. Jason brought with him 19 years of mechanical service experience from the automotive industry.

We are located in a 9,000 square foot facility in Winter Haven, Florida giving us plenty of area to bring in the largest units for repairs or complete rebuilding.


We have a large inventory of after market and original OEM spare parts for Westfalia and Alfa Laval Centrifuges. We also have a good inventory of new and reconditioned tools - offered at reduced prices. We have many hard to find parts along with spare hoods, frames, and covers. We also have in stock several used bowl parts, discs, separating discs, distributors, and pistons. Instruction manual and parts lists are available for many units.

We can repair your piston lips and seal rings with a one to two week turnaround with hard surfacing. We repair feed tubes and centripetal pumps.

Voith clutches repaired and rebuilt along with sales of new or reconditioned units. We have test units and rental units available to do lab testing for new applications.


If you are tired of paying high costs to have maintenance performed on your centrifuges, we would be glad to work on your site with your maintenance personnel to train them to rebuild the drive assemblies on both gear drive and belt drive units. Combine this with high quality parts and you can save as much as 25% - 35% on your maintenance costs. These training sessions can be video taped to refresh your personnel or train newly hired personnel at a later date.

We have in stock several centrifuges of varying sizes, reconditioned and ready to be put into immediate service. All reconditioned machines come with warranties. We also have several other units to be reconditioned. If the unit you are interested in is not listed, we will do our best to locate it for you. Most centrifuges sold include no additional cost for start-up and training of operating personnel. Also in some cases, price includes delivery.

If you have any centrifuge equipment you would like to sell as is, or reconditioned, SJS Machinery would work with you to sell it on consignment. Or if you have existing units in need of reconditioning or repairs, contact us for all of your centrifuge needs.
