Courses

PS4B

Single spring pusher seals
Performance capabilities:

● Pressure: 0~3.0 MPa

● Temperature: -40~260℃

● Speed:≤25m/s

Descriptions:

√ Single springs with excellent capabilities of anti-clogging and anti-corrosion, designed for a small amount of particles containing or easy to crystallize media

√ Compensating for large axial movement

√ The structure of mating rings benefiting for good installation of seal faces without sloping

√ Torque transmitted by shifting forks with strong transmission capacities and independent of rotation direction

Features:

● Single springs, rotary

● Shifting forks drive

● Standard floating bushing

Recommended applications:

√ Sewage pumps

√ Alkali pumpS

√ Refining & petrochemical

√ Coal chemical

√ Chemical

√ General industry
