High Performance V-Shaped Seal Ring Lip Seal for Pump/Presses

Product Description

Product Description

V Packing Seals are one of the seals used for reciprocating motion, its section shows a V shape. We seldom use them alone, normally, combination using of pressing ring, back-up ring and several v rings, the number of v rings depend on the pressure.

V-shaped seal ring is a shaped packing seal, the cross section of v-shaped lip seal ring.

V Packing Seals are mould pressing of rubber with fabric or rubber, normally NBR with fabric, hard rubber for press ring and back-up ring, hard plastic is also used for back-up ring. V Packing Seals mainly apply to piston and piston rod of overload equipments, providing good abrasive resistance and stability, as well as preventing extruding seals out of the gap. Moreover, it can provide best sealing even under harsh condition, like temperature change, unexpected pressure, axial/radial vibration, etc.

As mentioned above, the V packing is generally composed of three parts, the middle V rings, and the upper and lower support rings and compression rings. V-rings can be 3 pieces,5 pieces,7 pieces etc…as you request.

Material:

NBR/FKM Fiber POM+PU+PTFE/PA/

Customied material is always welcom, like FKM(PTFE), FKM with fabric, NBR are all available.

Material Character Profile:
Pure Rubber: Water and air
NBR: Mineral oil based hydraulic fluids
FKM(PTFE): Various kinds of chemicals and high temperture
Rubber with Fabric: Strengthen sealing rigidity and intensity, preventing extrusion, fitable for high pressure.
PU: Abrasion resistant
PTFE+Carbon: Preventing extrusion

Product Function:

It is suitable for reciprocating movement of the piston or piston rod for dynamic sealing, but also can be partly used for rotation, rotary or static sealing parts.

Application Range:

Temperture: -25° C-+200° C
Pressure: Under 40MPa
