Packing

Typically consists of braided or formed rings that are compressed in the stuffing box of the pump. As the packing is tightened, it squeezes up against the shaft and the stuffing box wall to create the seal. Click here to view the Pump Report on this topic.

Sealless Mag Drive

Comprised of two independent shafts; one connects to the drive and other connects to the pumping elements. A magnetic coupling transmits the rotation of the drive shaft to the driven shaft inside the pump. Click here to view the Pump Report on this topic.

Lip Seal

Consists of a flexible elastomeric lip in a rigid housing. The lip seal is stationary and the shaft rotates inside. Click here to view the Pump Report on this topic.

O-ring Seal

Any seal consisting of one or more elastomeric O-rings. These may be static seals wherein there is no relative motion between parts (i.e. an O-ring seal between a pump casing and bracket) or dynamic seals wherein the seal is created between a moving shaft and a stationary housing (i.e. O-Pro® shaft seals)
