Enerpac PA166 Air-hydraulic Pump 10000 Psi

Product Description

The ENERPAC PA166 is an air-hydraulic pump rated to 10,000 psi, designed to power single-acting hydraulic cylinders in industrial and trade applications. It uses compressed air to develop high hydraulic pressure, delivering a reliable advance, hold, and retract operating cycle. With a 72 cubic inch reservoir and an air requirement of 60 to 100 psi at 9 CFM, the PA166 is suited for controlled, high-force tasks such as pressing, lifting, clamping, and straightening. The unit weighs 16 pounds, making it portable enough for field or shop use. Licensed hydraulic technicians, pipefitters, and mechanical contractors are the typical end users for this class of pump.

The PA166 is used in applications requiring sustained hydraulic pressure without a manual pump operator continuously actuating a handle. It fits naturally into production environments, maintenance shops, and field service situations where a compressed air supply is already available. Single-acting cylinder setups are common in vertical lifting and horizontal pressing operations, and this pump supports those workflows with consistent pressure delivery up to 10,000 psi. The advance, hold, and retract cycle allows the operator to extend the cylinder, lock pressure during the work phase, and then release for retraction.

Key Features

• 10,000 psi maximum operating pressure for high-force hydraulic applications
• Air-over-hydraulic actuation eliminates manual pumping effort
• 72 cubic inch usable oil reservoir capacity supports extended stroke cylinders
• Operating air range of 60 to 100 psi at 9 CFM suits standard shop air supplies
• Single-acting design with advance, hold, and retract cycle control
• Portable at 16 pounds for field and bench use

Compatibility

Designed for use with single-acting hydraulic cylinders. Specific compatible cylinder models were not provided in the product data; consult ENERPAC compatibility documentation to confirm fitment with a specific cylinder series.

Installation Notes

Installation and connection should be performed by a qualified hydraulic technician or mechanical professional familiar with high-pressure hydraulic systems. Before connecting or disconnecting hydraulic fittings, relieve all system pressure and verify the air supply is isolated. Ensure all hydraulic hose connections are rated to at least 10,000 psi working pressure and are free of damage before pressurizing the system. Follow applicable OSHA and equipment-manufacturer safety guidelines when operating hydraulic tools under load.
