This EMMAR-manufactured pulley, identified as POLEA 800 3C, is a power transmission component that mounts on a machine shaft and drives it through V-belts. It is specified for drives that need to transmit torque using several belts side by side, including mills, mixers, compressors, high-flow pumps and industrial fans. The large diameter helps lower the driven shaft speed while preserving load capacity.

The designation POLEA 800 3C gives you the key data: an 800 mm diameter, three grooves and section C. Section C refers to the wide-profile V-belt that fits the grooves, and having three grooves means three belts can run in parallel on the same pulley. That arrangement increases the power that can be transmitted without changing the diameter. The part is manufactured by EMMAR, with the grooves machined to the angle and depth that section C belts require.

You will typically find this pulley on machines that run at low speed and demand high torque, such as mills, horizontal mixers, screw compressors, high-flow centrifugal pumps, induced draft fans and chain conveyors. It also serves as a reduction pulley in drive lines where the motor runs fast and the driven equipment runs slowly. In every case, the pulley works with a shaft, keyway and fastening system that must be in good condition.

When selecting or mounting the pulley, start by confirming the shaft diameter and the fastening method, whether keyway, taper bushing or set screw, because the pulley is machined to those specifications. Then check the center distance and the belt length available: with an 800 mm diameter, belt length changes significantly compared with a smaller pulley. Align the pulleys using a straightedge or laser, and tension the belts according to the belt manufacturer's instructions. A misaligned pulley wears the grooves and shortens belt life.

If you need a different diameter, a different number of grooves or a pulley for section B or D belts, manufacturing can be evaluated. We can also assess a replacement for an existing pulley if you provide the outside diameter, shaft diameter, number of grooves and belt section.
