Conn-Weld’s Sieve units are the result of over 35 years field experience working with plant circuits and systems. Advantages such as the quick reversal turnaround system and adjustable feed gate are proof we listen to You and design for You.

Conn-Weld manufactures the widest range of profile sieve screens in the industry today, with particle separation ranging from 50 microns and up. The profile screen surface has knife-sharp edges for removal of layers of liquid and undersize material as the liquid passes the opening thus preventing blinding of the slot opening. Conn-Weld’s unique Feed Gate is designed so that the operator may adjust and clean the opening to evenly distribute the slurry across the entire width of the screen at right angles to each knife sharp profile wire and slot opening.

Every sieve unit is manufactured with high specifications and durable components for maximum uptime and easy maintenance. Conn-Weld profile sieve screens are manufactured with a sharp cutting edge to slice away the slurry.
