Robust and Hygienic Conveyor Belt Drives For Food Processing

Improves Plant Hygiene
Thanks to its flat, smooth, stainless steel surface and hermetically-sealed design, the Rulmeca drum motor is easy to clean. The Rulmeca drive reduces the risk of contamination in food processing environments.

Resists Harsh Operating Conditions
The Rulmeca IP69 sealing system protects the drum motor from the most aggressive operating conditions. Neither the presence of water, chemicals, grease, and oil nor high pressure wash-down procedures are problems for the drive.

Improves Personnel Safety
The Rulmeca drum motor protects plant personnel from pinch points as well as slip, trip, and fall hazards because it encloses all moving mechanical parts within a pulley shell . The drive eliminates the need for expanded metal guarding around rotating shafts, external gearboxes, motors, and cooling fans.

Reduces Maintenance Expense
Since the Rulmeca drum motor does not use external bearings, which require greasing and inspection, but rather encloses all mechanical parts within an oil-filled shell, it reduces maintenance requirements to a fraction of what exposed drive systems require.

Makes Installation Easier
Since the Rulmeca drum motor is compact, lightweight, and pre-aligned, installation is quick and easy. Setting the drive only requires four bolts and electrical termination. Installation time is usually 1 to 2 hours. Heavy external gearboxes and motor frames, as well as guarding around rotating shafts, are eliminated.

Reduces Energy Consumption
Rulmeca drum motors require less than 90% of the electrical power of exposed drive systems when compared with motor/reducer/chain & sprocket or motor/reducer/V-belt drive configurations.

“Food conveyor drive systems are subjected to some of the harshest operating conditions imaginable. While maintaining a hygienic exterior surface, these drives must endure frequent high pressure, high temperature wash downs. That’s why Rulmeca’s hermetically sealed, internally powered, drum motors are the drive system of choice for conveyor operators and designers worldwide. We offer our customers The Rulmeca Advantage, but what does that mean to food processors? Enclosing the drive motor and all mechanical parts within the pulley shell keeps these items out of harm’s way. However, maintaining an effective hermetic seal long-term can be a challenge in food processing, especially at the interface between the stationary pulley shaft and the rotating end housing. Recognizing the need to specify a seal’s ability to withstand high pressure wash down, the international electro technical commission introduced the classification IP69.

To pass the IP69 test, a seal must be able to resist infiltration while subjected to four 30-second tests with a water spray at 1500 PSI, at a temperature of 180°F, at a rate of four gallons per minute, at a distance of 4” to 6” at four different angles. Rulmeca engineers developed, tested, and refined the seal system shown here.

Generally used with stainless steel drum motors intended for food processing applications, the Viton double lip seal, the PTFE fluoropolymer deflection seal, and the roller-burnished shaft are the secrets to success. Preventing water infiltration under these conditions guarantees that the Rulmeca drum motor, with our IP69 sealing option, will yield a long, reliable service life, even in harsh food processing operating conditions. Our drum motors have been known for their reliability for more than 60 years. Reliability is a big part of The Rulmeca Advantage. Contact us and allow us to put The Rulmeca Advantage to work for you.”
