Pressure Gauges are used to monitor the injection pressure of the grout being delivered to the grout hole. It helps to insure that the maximum allowable pressure is being applied to achieve the desired results of the grout program design. It also helps to prevent the application of an injection pressure that is too high and could overstress the foundation materials and the structures being grouted.
Pressure Leaf Covers are used for filter aid type of filtration of edible / non-edible, castor, vegetable, palm, oils and various chemicals. They find applications in all oil & chemical industries to separate solid particles up to 5 microns in size. In most pressure leaf filters, a filter cover fits over a frame in a pressure vessel. The chamber is filled with slurry and pressure forces liquid through the cloth, into the leaf and out of the drain port.
