"B" Flange Pump - 2 Bolt Mount
The SP25A pump now
utilizes self-lubricating thrust blocks that eliminate the need for separate
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 features a robust fluoropolymer 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.
Patented
Non-Symmetrical Gears - the adoption of non-symmetrical gears ensures 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 ensures 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.
