PUMP & MOTOR
Gresen Pumps have become the choice of major original equipment manufacturers. These
pumps have been designed to operate under the most demanding conditions. From prolonged
use to contaminated environments - we know what your system must face each day.
Whatever your application, Gresen has a pump to meet your needs. Standard pumps, dump pumps,
dry valve pumps, wet valve pumps, and valve/pump combinations offer a wide variety of alternatives
to give your system the flow required to operate at peak efficiency. Other options
include a variety of compact frame sizes, mounting configurations and shaft, flange
and porting designs to fit your application. In addition, you can choose from
aluminum or cast iron construction and single or multiple sections.
To us, efficiency means many things, including saving horsepower,
reducing fuel usage and lengthening the service life of the pump, as well as the entire system.
As a result, Gresen pumps are designed with various features to increase
your systems efficiency. Gear pumps range from 0.0014 GPR to 0.0832 GPR and flow
capabilities for single-section pumps range from 1 GPM to 200 GPM. Gresen pumps can also accommodate pressures
up to 4000 PSI. In addition to conventional gear pumps, High Speed Low
Torque (HSLT) gerotor style pumps and motors are also offered by Gresen. These pumps and motors
range from 0.00095 GPR to 0.00303 GPR, accommodating pressures up to 2500 PSI and speeds up
to 5000 RPM. Vane pumps are also available.
To ensure the quality and durability of our pumps, experts conduct
tests on the volumetric efficiency of units. Random life-testing over one
million cycles is also conducted under controlled conditions in a lab
capable of testing pumps up to 600 HP. The result is a pump you can depend
on to keep your system flowing efficiently.
Gresen directional control and accessory valves offer you the flexibility
to make your system operate the way you need it to operate. With a wide array of valve
styles and operating capabilities at your selection, Gresen valves maximize the control of
your system through various valve combinations limited only by your imagination.
The strength of monoblock designs, the versatility of sectional designs and the
flexibility of various porting, spool action and circuit options,are just a few of the fundamental
benefits youll find with Gresen valves.
even smoother operation and tighter control, we offers pressure compensation and electronic
control options. Pressure compensation allows you to maintain constant flow and control
regardless of load changes, while electronic control options permit precise metering of
flow and gradual adjustments in speed. Gresen can also prepare your system for remote operations
through pneumatics, hydraulics, or electronics. For even greater efficiency
from your system, explore the variety and benefits of Gresen accessory valves. Choose
between block and cartridge styles in different design options, including valve combinations
in integrated circuits. And if your imagination has conjured up a unique valve
design or spool to enhance a new or existing application, Airline is there to create a
tailor-made design to turn your vision into reality. The standard line of Gresen accessory
valves can accommodate pressures up to 5000 PSI and flows up to 60 GPM.
simple operation, low pressure drops, and low leak-down rates are advantages of Gresen valves.
From the castings to the spools, seals, springs and poppet seats, these directional control
and accessory valves are built to give you the control your system needs.
The ability to perform precise mobile fluid power operations, without slow and
awkward adjustments, is critical to meeting tight schedules and tight budgets. With Gresen
electronic controls, beating such deadlines and providing your customer with accurate,
cost-effective results have become much easier. By combining electronic- and
computer-based technologies, Gresen has produced a variety of electronic valves and
controllers to increase the precision of your system. These products, together with
Gresens advanced logic boards, make the operation of hydraulic controls an almost
effortless task. Yet, hydraulic response remains quick and accurate. The benefits of such
controlled performance enhance any operation - whether your application requires complex
proportional control or simple on/off capabilities. The Gresen Electro-Proportional Control
(EPC) valves give you the power to create a new proportional control system. The digital
capabilities of these valves produce exceptional control over pressure or flow. However,
if you have an existing hydraulic or mechanical system you would like to convert to
proportional control, we have has the electronic controls to fit your needs as well.
Pulse Signal Manifolds (PSM) are available to adapt existing hydraulic piloted valves to
proportional control. In addition, Pulse Signal Actuators (PSA) are available, providing
the flexibility of bolt-on proportional control to existing lever valves.
If your application requires standard on/off capabilities, Gresens solenoid valves are
the ideal choice. These valves supplement the performance of many Gresen directional control
and accessory valves by providing the precision and quick response available through
electronic control. Pulse Width Modulation (PWM) is the signal that enables you to
digitally control your system. Not only does Gresen provide logic boards to convert
electronic signals into PWM, but it also offers boards to transmit digital data. Other
Gresen electronic products include joysticks for infinite variations of digital control
and hand terminals for on-site system set-up, calibration and troubleshooting. In
addition, control boxes and a selection of remote controllers for single or dual
configurations and proportional or on/off applications are available.
The invaluable component of any mobile fluid power system is a filter. Whether
or not your system operates in a highly contaminated environment, filters are necessary
to refine your systems fluid and to maintain the service life of system components.
Gresen offers a complete line of high quality filters, including spin-on filters,
replaceable element canister filters and sump strainers. These filters feature a wide
range of elements, from cleanable wire mesh to high-performance fiber glass elements. You
can also choose from NPT, SAE, or BSP port options. Aluminum heads are standard on all Gresen
filters, and cast iron heads are optional on several models. Bypass valves are another
standard feature on the appropriate filters. Not only do Gresen filters handle the
contamination of your environment, they also withstand a broad range of demanding
operating temperatures - from -65° F to 250° F. In addition, filter condition
indicators, as well as pressure and vacuum gages and switches are also available to
assist you in maintaining the efficiency of your system.
or not your system operates in a highly contaminated environment, Gresen filters help
keep your system refined; and as a result, are ready to operate at your command.
