Seital Separation offers a variety of separators including: dairy, milk and cream separators. A direct drive option is offered for a range of these centrifuges.
In direct drive centrifuges the motor shaft and the centrifuge shaft are the same part. Direct drive centrifuges utilize less energy, require less maintenance and take up less space.
SPX® FLOW offers a direct drive option for a range of Seital centrifuges including separators with milk-skimming capacities of 5-10,000 l/h (1,320-2,642 gal/h) and standardization capacities of 8-14,000 l/h (2,113-3,698 gal/h).
In a direct drive separator, the motor shaft and the centrifuge shaft are the same part, replacing the indirect gear- or belt-driven transmissions of traditional separators. This uses less energy, requires less maintenance and takes up less space.
Using less energy
Direct drives are the most advanced way to translate energy from a rotating motor shaft in a centrifuge. Transmitting energy directly eliminates multiple connecting points, each of which would have increased the potential for energy loss. The longer your process runtime, the greater will be your energy savings.
Eliminating the need to change belts removes a significant maintenance task. With fewer moving parts, direct-drive centrifuges are also easier to assemble and disassemble. This makes them easier to tune and repair, maximizing uptime and thus reducing the overall cost of ownership.
Eliminating the gear or belt transmission parts gives a more compact footprint enabling more space-efficient, streamlined process lines.

How it works
In traditional separator designs, the motor and centrifuge shaft are discrete units that must be connected to transfer energy from the motor to the shaft. Traditionally, this connection is indirect, in that an intervening mechanism makes the connection. In one common approach, a system of gears translates the motion from the rotor to the shaft. Another approach uses a drive belt to transmit energy. While both geared and belt-driven systems are highly reliable, having so many moving parts contributes to loss of energy during transmission.
Direct drive systems accomplish the transmission with fewer parts as the motor shaft becomes the centrifuge shaft. The motor mounts directly beneath the bowl and its single shaft extends directly into the bowl. Driving the centrifuge directly from the motor minimizes energy lost in the process, enables more compact designs and reduces the maintenance that gear-or belt-driven systems might require otherwise.
Dairy - direct drive equipment is suitable for all separation of raw milk into skim milk and cream applications at all temperatures as well as for bacterial clarification. Because these applications tend to operate and high volumes for extended periods, energy savings go directly to the bottom-line.
Beverage – direct drive centrifuges can reduce energy consumption and maintenance costs in many beverage separation applications such as wine, tea, and coconut water.
Brewing – as with traditional separators, brewers would choose direct-drive separators to remove residual yeast and other non-soluble solids that might impact flavor and aroma. Plus, for those whose process line is customer-facing the compactness of the direct system contributes to sleeker plant designs.
Oils - processing of edible oils, essential oils and vegetable oils often have long production runs and limited installation space therefore could benefit from the compact and energy-efficient centrifuge operation.
