Enclosed Low Noise

Hydraulic Power Units are built to your specifications. Our knowledgeable estimators ask the right questions to help define your needs. Call us to discuss your flow, pressure, and control requirements and we will propose our solution in detail.

How to reduce noise in a hydraulic system? Noise certainly cannot be eliminated, but a number of products and techniques exist to bring the noise down to an acceptable level. Pump controls that lower pump pressure (when not needed) are energy and noise reducers. Electric motors with lower RPM and vibration dampening mounts are also effective. Fluid conductors (tubing, hose, fittings), often are overlooked as noise sources. Plumbing techniques are used with Pulse-Tone hydraulic shock suppressors to reduce noise as well. Installing sound-damping materials around the motor pump or power unit is also very effective.

Low noise Hydraulic Systems don’t just happen. They’re a result of careful design and well-planned installation strategies.

Overhead Reservoir

Hydraulic Power Units are built to your specifications. Our knowledgeable estimators ask the right questions to help define your needs. Call us to discuss your flow, pressure, and control requirements and we will propose our solution in detail.

Why use an overhead reservoir? Typically overhead reservoirs are used on large volume hydraulic systems which produce significant flow. This ‘reservoir over pump’ design provides a positive head pressure to the inlets of the pump(s) which is good practice and extends the service life of any type of pump. Additionally, this arrangement conserves floor space and offers easy access to the reservoir for maintenance.

FAQs

What is a custom hydraulic power unit?

A custom hydraulic power unit is a hydraulic system engineered specifically for an application’s pressure, flow, control, and operational requirements rather than using a standard off-the-shelf configuration.

What information is needed to design a custom HPU?

Typical requirements include:

Operating pressure
Flow rate
Motor voltage
Duty cycle
Reservoir size
Available footprint
Environmental conditions
Control requirements

What industries use custom hydraulic power units?

Custom HPUs are commonly used in manufacturing, marine systems, heavy equipment, automation, oil and gas, recycling equipment, presses, and OEM machinery.

Can Atlantic Hydraulic Systems build OEM hydraulic power units?

Yes. We design and manufacture custom hydraulic power units for OEM applications including integrated controls, manifolds, filtration systems, and compact packaging requirements.

How to Select Pump and AC Motor Combinations:

A pump/motor combination should be selected which doesn’t overdraw the motor in the worst case flow and pressure condition.

Example: HPmotor <= FLOWgpm x PRESSUREpsi / 1500

HPmotor <= 3gpm x 1000psi/1500

HPmotor = 2

How to Select Pump and DC Motor Combinations:

Select the correct motor and pump for a given application. Ensure proper pressure, flow and electrical amp draw for the application. Pump/motor curves are available in the Full Catalog for various combinations of pumps and motors.

There are motor curves for both S2 and S3 duty cycle categories.

  • S2- Absolute Continuous On-time. Indicates how long a motor can be run continuously before it must be allowed to cool back to ambient temperature.
  • S3- Percentage On-time. Based on a 5 minute duty cycle, it indicates the duty cycle the motor can be run continuously without overheating the motor.
