Pressure Piston Pumps高压活塞泵
|
Compact, High-Pressure Piston Pumps |
|
PF500 Series fixed
displacement pumps operate at maximum pressures to 8000 psi (560 bar)
continuous and 15 000 psi (1040 bar) intermittent.
Low Input Power
Input power
requirements, as low as 1 HP at 10 000 psi (0.7 kW at 700 bar), make these
pumps ideal for use in remote locations with limited power supply.
Flows from 0.22 to
0.70 U.S. gpm (0,83 to 2,65 L/min) at 1800 rpm are available in four models.
Multiple Output Pumps
Split-Flow®
models provide multiple outputs for synchronized actuator movement or
multiple function circuits.
These multiple outlet pumps
can efficiently supply flow in a circuit with changing flow and pressure
requirements. This makes them ideal for Hi-Lo circuits on clamping, pressing
and high-pressure tool applications.
Bi-Directional Shaft Rotation
With these fixed
displacement pumps the direction of output flow is constant, regardless of
drive shaft rotation. Bi-directional shaft rotation can be an advantage
when using double-ended electric motors, requiring only one model to be
specified.

Oil & Gas
Industry Pumps
PF500 Series checkball design
pumps, with individual piston check valves, provide long life in
adverse conditions.
High pressure
capability and low input power requirements make these pumps ideal for
land-based
Wellhead Safety Panel Systems. They especially provide an advantage
on solar or wind-powered systems in remote oil field locations where
power supply is limited.
The pumps can
also be used on portable power packs for high-pressure torque wrenches
and other service tools.

Selection Notes
-
Output flows are based
on typical performance using 100 SUS (20 cSt) mineral oil at rated pressure
with pressurized inlet where required. Consult the Dynex sales department for
minimum inlet pressure and for a review of applications requiring
continuous-duty at rated speeds higher than 1800 rpm or lower than 900 rpm.
-
Ordering these pumps
requires a complete model code specifying seal and port options.
-
Models with the high
pressure "H" option require the use of outlet port option "A" (Autoclave/Butech
fitting) or "B" (British Standard Pipe Fitting). Pumps with ports for
standard S.A.E. fittings are not recommended for operation above 8000 psi
(560 bar). Contact the fitting manufacturer for the pressure rating of the
fitting.
