Buying Guide

Match pitch and circumference

Confirm your pump pulley uses an 8M pitch and choose a belt with the correct outer circumference (e.g., 896 mm, 1264 mm, 1728 mm) to avoid re-tensioning or re-sprocketing

Confirm belt width

Use the specified 20 mm belt width when your pulley and tensioner support it; incorrect width can reduce load capacity or cause misalignment

Check material and reinforcement

Look for belts with durable backing and tensile cords appropriate for industrial drives to resist stretch and extend service life under continuous pump operation

Consider value vs. size

Compare price across similar OD belts—moderately higher cost can reflect better construction for larger diameters used in heavy-duty pumps

Verify compatibility, not just size

Cross-reference OEM part numbers or measure tooth profile and pulley dimensions; identical circumference alone doesn't guarantee a proper mesh
