The 800 2B pulley is a V-belt drive pulley manufactured by EMMAR Accesorios Industriales. It has an 800 mm diameter and two grooves for section B belts, which allows power transmission between parallel shafts with a drive ratio defined by the diameters of the system's pulleys. It is used in equipment where large volumes of air or material need to be moved with a single motor, such as industrial fans, screw compressors and conveyors.

This pulley has an 800 mm outside diameter and two machined grooves for section B belts. Section B is one of the most widely used in power transmission: it accepts classic-profile belts and is available from any spare parts supplier. The two grooves double the transmission capacity compared with a single-groove pulley of the same diameter, while keeping the same pitch diameter. The hub is machined to mount on the equipment shaft, with keyway and set screw as ordered.

Typical applications for a pulley of this size are high-flow centrifugal fans, screw compressors, mills, mixers and belt conveyors. In all these cases the goal is to reduce motor speed so the equipment runs in its optimal range, or to increase the available torque. It is also used in belt-driven machines where a large-diameter drive pulley is needed to avoid overloading the belt.

To select a pulley of this type, you must take into account the power to be transmitted, the RPM of the faster shaft and the desired drive ratio. With that data, the pitch diameter of the drive pulley and the number of grooves are defined. Section B accepts a limited range of pitch diameters, so it is advisable to verify that the chosen diameter is not below the minimum recommended for that section. Installation requires aligning the pulleys and tensioning the belts according to the deflection specified by the belt manufacturer.

If you need a pulley with a different number of grooves, a different diameter or a different section, we can manufacture it. We can also quote a pulley equivalent to the one you are using, based on the outside diameter measurement, the shaft diameter and the belt section. Send us that data along with a photo of the old pulley and we'll send you the quote.
