To satisfy the ever increasing demand for faster. more positive
acting original equipment, fluid power components are needed
which will perform more satisfactorily at higher operating pressures.
Heavy duty gear pumps anti motors are preferred over vane or
piston types due to their simplified construction, their ability to
stand up under rugged operating conditions and their economies in
cost and maintenance. COMMERCIAL Model 15H pumps and
motors were made available to meet this demand. They are
suitable for continuous heavy duty service at 2000 psi. Since their
introduction, they have met with outstanding acceptance as proven
by their wide usage on equipment in the OEM market.
Insuring dependable, long life operation, Model 15H pumps anti
motors are of heavy duty construction throughout. They are made
with fewer working parts thin other types of pumps or motors. Extra
heavy bearings, four to each single unit, are placed on the ends of
each gear anti are designed to take all unbalanced loadings,
prevent shaft misalignment anti eliminate corner loading and
spawling. .All castings are of a special alloy iron, precision
machined, with metal positioned to resist bursting under severe
shock loading. Thus, these long life units are a result of years of
experience and "know how" built into every COMMERCIAL pump
Accurate alignment of finely machined parts under load, excellent
lubrication, positive scaling of blocked oil passageways and perfect
joining of gear contact surfaces are check points to consider in
evaluating performance characteristics of pumps and motors.
Ratio of output to input is much higher than normally associated
with gear pumps or motors, particularly when operating at pressure
as high as 200 psi. Complete performance data pertaining to
COMMERCIAL. Motel 15H fluid power pumps and motors is
recorded on pages 10 through 19.
