Tecumseh Industries Ltd. would like to introduce our TEC-1655-Fixed Main Variable Conveyor (FMVC) centrifuge. This centrifuge was developed with the aim to provide customers with a cost effective Class 1, Div. 1 option for utilization in “barite recovery” applications as well as normal solids control or “polishing” applications.

This centrifuge is equipped with a 2 speed main drive as well as with a 2 speed conveyor drive, which has turned the 1655 into a true performer!

The 2 main drive speeds are accomplished by using a 2 step sheave design with a 60hp explosion proof motor.

By simply changing the main drive belt configuration, operators can change the main drive operating speed to accommodate barite recovery (for high gravity solids) or polishing applications (for low gravity solids).

This model is available with an electronic soft start or a fluid coupling type soft start. Please note that the model with the fluid coupling has a larger footprint than our compact models.

The 2 conveyor drive speeds are accomplished by utilizing a forward/reverse motor contactor, which is used to change the direction of the conveyor drive motor allowing for 2 different differential or conveyor speeds. A 3rd differential speed can also be accomplished by simply locking out the conveyor drive assembly, which essentially turns the conveyor into a true “fixed” conveyor (same as our 1655 FMFC model).

This simple conveyor drive configuration eliminates costly electric motors with brakes and increases reliability. Parts are also readily available, and in most cases are “on the shelf”, which minimized downtime.
