MuPu Seals
MupuSeals*
Mupusealing systems consist of a range of static and dynamic high performance MupuSeals, designed for
applications where the physical and chemical working conditions are beyond the limits of traditional seals.
Thus the O.L. Mupusealing system is highly applicable most equipment serving in chemical-, food-, petrochemical-,
offshore- and cryogenic industries. *MupuSeal is short for Multi Purpose seal
The MupuSeal concept
The MupuSeal is energized by a metal spring with carefully chosen characteristics.
The dynamic seals are furnished with springs that maintain their force over a wide deformation interval. This means
that the spring force remains practically constant during the life time of the seal. The static seals are furnished with
springs that ensure a high uniform force on the entire circumference of the seal.
Advantages of MupuSeals
Wide fluid range
MupuSeals are resistant to a wide range of chemicals and will not contaminate the fluid.Wide temperature range
As the spring is virtually unaffected by temperature the MupuSeals will maintain their good properties from low to high temperatures.Easy to sterilize
Because of the chemical and thermal resistance MupuSeals are easy to sterilize. Even a light radiation may be used for sterilization.Service life
The excellent wear resistance of the Kefloy materials and the permanent elasticity of the springs assure the MupuSeals a very long service life.Shelf life
Can be stocked indefinitely.Low friction
The Kefloy materials have a very low coefficient of friction.No stick-slip
The static and the dynamic coefficient of friction of Kefloy is almost identical. This ensures a stick-slip free start and stop and a smooth and chatter free travel plus the possibility of accurate positioning.
Applications
The MupuSeals presented in these data sheets are all single acting. Double acting seals and special designs are
made on request. Please contact your local distributor.
In these data sheets we present both static and dynamic seals. The dynamic seals include seals for reciprocating
and rotating movements. The static seal covers seals for axial sealing as well flange seals.
Groove design
The groove dimensions for the standard MupuSeals are identical to grooves for O-rings according to the standards:
ARP 568A, DIN 3771 and ISO 3601/1.
