Literature Available On New Mechanical Pump Seals From Drew

Drew Ameroid" Marine has introduced a new design series of replacement seals to fit most standard ship pumps. The AMERSEAL" 10 mechanical seals are available through nearly all major ports worldwide for fast, economical installation.

They are designed for versatility and reliability in fit and are stocked in the most popular sizes to provide fast service.

AMERSEAL 10 mechanical seals are cartridge-mounted and preset at the factory so that upon installation common misalignment errors are eliminated. They are nonfretting and self-squaring. The universal design of the gland plate allows the seal to adjust to fit the bolt circle of existing pumps, eliminating the need for machining special hardware. Pumps with identical shaft sleeve diameters, but different bolt circles, are therefore accommodated with one seal.

AMERSEAL 10 is hydraulically balanced for use in high or low pressures. During service, hydraulic pressure activates a piston device, forcing the springs into their drilled recesses. This seals off the springs from clogging deposits, allows the hydraulic pressure to align the stationary face to shaft center-line, and eliminates spring fatigue. Since the seal remains stationary while the shaft rotates, it is not subject to stress of centrifugal forces.

Made of the highest quality materials, AMERSEAL 10 is built for endurance and, because of the design, repairs are easily accomplished at minimal cost, using a repair kit.

Seals are pressure rated to 23.8 kg/cm2 and temperature rated to 204 degrees C. Sizes are inventoried to meet all popular pump shaft measurements, from shaft diameters of 30 mm to 65 mm and lVa inches to 29/i6 inches.
