SP Series Hydraulic Gear Pumps - Prince - Prince SP25A Series Hydraulic Gear Pump

Brand: Prince

Style: SAE "B" Flange Pump - 2 Bolt Mount

The SP25A pump now utilizes self-lubricating thrust blocks that eliminate the need for seperate wear plates.  They are made from a high strength aluminum alloy with exceptional anti-galling properties.  This new thrust block design also incorporates advanced bearings designed specifically for high pressure hydraulic pumps.  This new bearing feataures a robust fluropolymer PTFE wear surface that yields unsurpassed load carrying capabilities and cavitations resistance even at low speeds and moderate levels of contamination.  Also, since the PTFE resin layer is self-lubricating, contamination from bearing wear in high load situations (when no oil film is present) is reduced.  This new thrust block design combined with these advanced bearing results in lower friction and less internal oil loss resulting in higher pump efficiencies.

Specifications

Features: Patented Non-Symmetrical Gears - the adoption of non-symmetrical gears insures greater power per unit volume compared with pumps of conventional design. The compact gear compartment has enabled high-pressure operation. The increased number of gear teeth has reduced the flow pulsation and minimized the noise.
• Bearings - PTFE composite bearings are used due to the ability to handle heavy loads, low shaft speeds, and high levels of contamination.
• Gears and Drive Shaft - Made of hardened alloy steel of one piece construction.
• Special Gear Design - Non-symmetrical gear insures low noise and compactness.
• Highest Quality Workmanship - Proudly made in the USA!
• Pressures up to 3000 PSI.
• Dependable Service - Balanced pressure loading insures small dispersion, good durability and maintains high performance.
• Extremely efficient.
• Perfect Alignment - "Through bore" design provides perfect alignment of pump element and assures even bearing load.
• With the aluminum alloy casing, the SP Series features light weight and easy handling.
• Working oil - a mineral based oil with additives to resist corrosion, oxidation, and foaming is recommended. Viscosity at any running condition should be 60 SUS minimum and 250 SUS maximum. 180°F is the maximum recommended system operating temperature.
• Per ISO cleanliness code level 17/14. As a minimum, 10 micron filtration is recommended.
