It is ideal for installation in pumps and agitators where it is difficult to remove the shaft and it handles normal pressure, temperature and speed. Because the seal is delivered in two halves which are mounted together with eight screws it is very easy to install. The seal is assembled outside the pump and then pushed along the shaft on to the pump cover and then the gland bolts are tightened. When the set screws are tightened the distance clips can be removed. Huhnseal FS is available in shaft dimensions between 40-200 mm. Patent 5662340.
