EATON 3044402 Hydraulic Power Unit

Eaton 3044402 hydraulic power unit, a PSSC Series horizontal packaged system provides power to industrial machinery like lifting equipment, lathes, presses and injection moulding machinery. This floor-standing power unit is equipped with a large-sized 30-gallon steel reservoir tank for powering larger systems in rugged conditions. It uses an AC power source for pressurising hydraulic oil and lifting / moving heavier loads in a smaller footprint while providing precise movement and speed control.

Working Mechanism:

• Select a clean well-ventilated area and install this 10 gpm hydraulic power unit.
• Fill the unit's reservoir with high-quality hydraulic oil through the equipped filler-breather. Fill the external horizontally-mounted piston pump's case.
• Use proper line sizing & cleanliness practices to connect the power unit's hydraulic pressure supply and return connections. Connect all other auxiliary functions like level switches.
• Connect the unit to an appropriate electrical source.
• Tighten the suction fittings to prevent the air from entering the pump. Start & stop the motor several times to prime the pump before beginning the full flow.
• The jog mode will be considered complete when the pressure gauge shows a positive pressure.
• Run the system at the minimum pressure & maximum flow for at least two hours for flushing the contamination to the return filter. Users may now start their operation.
• After a few complete cycles of the system, recheck the reservoir oil level and refill if required.

Features:

• Eaton 3044402 hydraulic power unit has a 10 hp, 50 / 60 Hz motor with 1800 rpm and a totally enclosed fan cooled enclosure.
• It uses a 10gpm 1-stage piston pump for a maximum pressure of 1470 psi.
• This 10 gpm hydraulic power unit is integrated with an adjustable relief valve and level switch for protecting the unit from over-pressurisation & over-filling.
• It has a 1-1/16 inch-12 (SAE 12) pressure port and 1-5/16 inch-12 (SAE 16) return port thread size.
• The unit's reservoir is fitted with a standard filler / breather for delivering clean hydraulic oil without any impurities.
• This unit is equipped with a pressure gauge with pressures ranging from 0 to 3000 PSI.

Frequently Asked Questions:

Q. What is the power rating required for operating this Eaton 3044402 hydraulic power unit?

A. This 10 gpm hydraulic power unit is powered by a 3-phase AC power supply rated at 230 / 460VAC and 28.4 / 14.2A.

Q. What is the pressure at which the relief valve of the unit activates?

A. Default pressure setting at which the relief valve activates is 2000 psi. However, users can adjust this set pressure for specific applications.

Q. What are the steps for maintenance of this Eaton 3044402 hydraulic power unit?

A.

• Motor bearings should be greased and the filters should be checked / replaced at least once a month. The hydraulic fluid condition should be checked at regular intervals to maintain the optimum component life.
• When using petroleum oil, recommended cleanliness levels should meet an ISO code level of 18 / 16 / 14 or better.
• Users should maintain the fluid level in the fluid reservoir between the high and low black lines on the sight-level gauge.
• After a year or 4000 hours of operation, replace the air vent filter and check the entire system for preventing future issues.
