The ability of the stator to flex is significantly enhanced with polyurethane, because the more the elastomeric stator can flex when sharp abrasive particles pass over it, the less wear occurs.

Traditional elastomers including nitrile (NBR), ethylene propylene (EPDM) and viton/fluorocarbon (FKM) are all used in cavity pumps The selection of the correct elastomer is just one part of ensuring reliable service and good performance

Nitrile is a good all-round elastomer for various chemical and slurry applications and tends to be the first choice for abrasive duties.

Viton has excellent chemical resistance properties, but performance is reduced if the liquid contains abrasive particles.

When selecting a pump, consideration should always be given to rotational pump speed.

The more the elastomeric stator can flex when sharp abrasive particles pass over it, the less wear occurs.

The ability of the stator to flex is significantly enhanced with polyurethane.

Torqueflow-Sydex can now offer the this material in virtually all of its pump range, providing enhanced reliability, service life and reduced running costs.
