Rulmeca Motorized Pulleys

Cranberry manufacturing benefits from more reliable, longer lasting and more sanitary drive technology

Who is Rulmeca?  What is a Rulmeca Motorized Pulley?
A Rulmeca Motorized Pulley is the ideal system for the drive of belt conveyors. Being composed of a motor, bearings and gearbox hermetically enclosed inside the casing, it is partially filled with oil that acts as lubricant and refrigerant to dissipate away the heat through the shell and the belt conveyor.  The main features of our Motorized Pulleys, all made by Rulmeca, are:

• reduced energy consumption
• increased efficiency
• ease of installation
• space-saving design
• designed for the toughest conditions
• guaranteed for food
• improved safety
• maintenance-free

The range of Rulmeca Motorized Pulleys have a 2 years’ warranty.

This is how we help.

​​This is an example of where Rulmeca provided all of the above improvements for a cranberry manufacturer.  The cranberry manufacturer was using exposed drives consisting of a right angle gearbox and motors, sometimes involving a coupled connection or chain and sprockets to the drive shaft.  These drives often times had drip trays under them to catch leaking oil from the output seals. 

Rulmeca Motorized Pulleys were installed and

• eliminated the drip trays and the risk of leaking oil into product
• requires only one component for a spare instead of the several with the motor, gearbox, chain, sprockets, coupling, etc.
• reduced safety guarding and increased safety with fewer pinch points
• is much easier to clean and protects against the high pressure/temperature wash down used with our IP69 seals (see below)
• more compact design allowing more room for operators and mechanics to work, especially in the inclined conveyors where there is limited room to work

Rulmeca Offers IP69 (food processing) Motorized Pulley shaft seal system

With IP69 rating Rulmeca offers complete assurance to food handling customers.
​
Rulmeca has received the certification of an upgraded Ingress Protection rating IP66/69 for drum motors 80LS, 113LS, 138LS and 165LS in stainless steel. The goal of the certification procedure was to achieve official IP69 (acc. to DIN EN 60529) confirmation of the current TS8N (complete stainless steel outer material with VITON dust lip seal and PTFE deflection seal) sealing system.
​
To provide absolute objectivity and safety the test was conducted at the independent VDE test and certification institute. In the test setup the drum motors have been mounted on a supporting structure and sprayed from 4 fixed angles (0°, 30°,60°, 90°) with a flat nozzle, each jet duration lasting at least 30 seconds. Distance between nozzle and test item was 100-150mm at a pressure of 100 bar with a water temperature of 80°C.
