The open circuit Premier Series
pumps are variable displacement
piston pumps with emphasis
on superior design with few
maintenance requirements.
Superior inlet characteristics
allow the pumps to run faster than
competitive models without the
added expense of boosting the
inlet. Modified pistons that reduce
the amount of trapped fluid volume
result in improved efficiency.
The Premier Series pumps have
been designed to operate on a
variety of fluid types and in a wide
range of industries where variable
flow, high pressure and/or high
speeds are required; such as:
presses, construction machinery,
injection molding, wood, aircraft,
drilling, mining, steel and cranes.
• Highest rated pressure of any
comparable pump available in
the market place today.
• Full power thru-drive capability allows two (2) pumps of the
same displacement to be run
in tandem at full rated pressure
and flow, simultaneously.
• Fast, compensator response
minimizes pressure overshoot.
• Two stage, pilot operated
compensator provides sharp
pressure cutoff at compensator setting, typically regulating
pressure within 50 PSI (3.5 BAR).
Compensator may easily be
remotely controlled or used in
load-sensing circuits.
• Precision barrel bearing
absorbs radial forces, allowing
longer operation at higher
pressure and higher speeds.
• Piston design minimizes
trapped oil volume to maximize
efficiency.
• Angled barrel ports reduce the
piston circle diameter, which
allows oil to enter at reduced
velocity. This allows the pump
to run faster, with atmospheric
inlet pressure.
• Spherical port plate and barrel
face provides support to barrel
to offset forces from angled
ports.
• Large suction port reduces inlet
flow velocity to allow the pumps
to run at higher speeds with
atmospheric inlet.
• Standard SAE split flange with
inch or metric bolts, depending on pump version (SAE or
metric)
Premier Series High Pressure/Performance Piston Pumps
• Conforms to SAE or ISO mounting standards.
• Damped low inertia rocker cam
allows very quick compensation, resulting in more stable
and quieter pump.
• Heavy duty shaft bearing to
absorb side and thrust loads.
• High pressure shaft seal allows
higher case pressure without
external leakage. Note: it is
always advisable to maintain the
lowest possible case pressure.
• Drive shaft options include
keyed or splined in SAE, ISO
and DIN.
• A wide variety of optional
controls are available and are
designed with simplicity and a
maximum of common elements.
