The Type P21 & P22 seals are Sturdy Multi-coilspring unbalanced Pusher Seals catering to most of low pressure process pump applications.

Enables handling of the abrasive and corrosive liquids, retaining the basic design philosophy of multi spring seals. Exotic compatible metallurgy for hardware is available.

Wedge or 'O' Rings allow lower spring loads and a cooler running seal. Shaft fretting is minimized.

The rotary face is shrink fitted in metal shell thereby giving additional advantage of offering both hard faces The springs

are fully immersed in the process fluid, hence do not get clogged because of the centrifugal forces.
Positive lug drive mechanism provides excellent torque transmission.

Can be provided as an engineered cartridge construction in single, double or tandem arrangements with a complete range of auxiliary sealing devices and seal support systems.
