At each end of the bundle a support plate assembly holds the membranes in proper relationship. Each support plate assembly comprises outer and inner plates and a sealing plate sandwiched therebetween. Each membrane extends through aligned holes in the three plates. The sealing plate, formed of an elastomer, includes outer and inner portions and an intermediate portion situated therebetween. The intermediate portion is in sealing relationship with the membranes. The intermediate portion is softer than the outer and inner portions, the Shore A hardness value of the intermediate portion being no greater than about 55, and that of the outer and inner plates being no less than about 65.
