US Seal PS-2170 Type U 1.75" Pump Seal Assembly

Features:

• Absolute Sealing: Proper selection and installation of seals result in less pumpage loss, cleaner facilities, less fire hazard, no danger from fumes, and no contamination of the fluid being pumped.
• No Rubbing Friction Between the Shaft and Seal Parts: Replace packing with a mechanical seal and avoid expensive shaft or sleeve replacements.
• Flexible Seals Mean Longer Service Life: Compared to packing, mechanical seals are more flexible and are able to compensate for shaft deflection, axial and radial end play, vibration, and seal face wear.
• Less Friction Means Valuable Power Savings: Mechanical seals use less friction than packing. Therefore, they require less horsepower consumption.
• Precision Lapped Sealing Surfaces: Positively control leakage and eliminate "break-in" runs.
• Higher Speeds and Pressures: The seals are designed for higher speeds and pressures.
• Flat Surfaces of Mating Faces: Sealing surfaces are precision lapped to a flatness of one to three light bands, which maintains the necessary face film lubrication, resulting in positive leakage control.
