ENERPAC

ENERPAC is a global manufacturer of high-pressure hydraulic tools and systems, with a product line that spans hydraulic pumps, cylinders, rams, torque wrenches, and accessories. Founded in the United States, the brand has established a reputation for engineering components that operate at pressures up to 10,000 psi, serving applications in industrial maintenance, construction, and heavy equipment repair. The product families include electric and pneumatic hydraulic pumps (e.g., ZE4408SB-T, ZU4420MB-G), single-acting and double-acting cylinders (e.g., HCL25010 lock nut ram, SLRD51 swing clamp cylinder), and specialized accessories such as extended reaction tubes (ERT19024) and flat bases (A243). Build standards emphasize durability under continuous high-load cycles, with components like rams featuring effective areas up to 56.27 sq in and capacities reaching 250 tons. IP ratings vary by model; portable electric pumps are designed for job-site conditions, while cylinders incorporate hardened steel and corrosion-resistant finishes. 3G Electric stocks over 2,400 ENERPAC SKUs, including replacement parts like rubber washers (DA5976108) and plungers (CA13604024), providing datasheets and logistics support for global procurement. The catalog covers torque wrench pump units with 3-position or 4-way control valves, general-purpose rams with lock nut mechanisms for load holding, and swing clamp cylinders for automated fixturing. Application categories include hydraulic power generation, linear actuation, and torque application, with each product specified by operating pressure, flow rate, stroke length, and mounting configuration. For technical buyers, ENERPAC components are designed to meet ISO and ANSI standards for hydraulic system safety, with traceable part numbers and compatibility across series. 3G Electric supports the line by offering detailed specifications, cross-reference data, and global shipping, enabling engineers and procurement specialists to source ENERPAC equipment without geographic restrictions.

Frequently asked questions

Common questions about ENERPAC from 3G Electric.

What is the maximum operating pressure of ENERPAC hydraulic pumps like the ZE4408SB-T?

The ENERPAC ZE4408SB-T electric hydraulic pump has a maximum operating pressure of 10,000 psi. This is typical for ENERPAC's Advance-series pumps, which are designed for high-pressure applications such as torque wrench operation and cylinder actuation. The pump also delivers a maximum flow rate of 60 cu in/min, suitable for single-acting or double-acting tools.

What is the capacity range of ENERPAC lock nut hydraulic rams like the HCL25010?

The ENERPAC HCL25010 lock nut hydraulic ram has a nominal capacity of 250 tons and a stroke length of 10 inches. Its effective area is 56.27 sq in, and it is part of the HCL series, which includes rams with capacities from 50 to 500 tons. The lock nut mechanism allows the ram to hold load mechanically after hydraulic pressure is released.

Are ENERPAC swing clamp cylinders like the SLRD51 suitable for automated fixturing?

Yes, the ENERPAC SLRD51 swing clamp cylinder is a double-acting, lower flange mount model with a clamping force of 1,250 lbf and an effective area of 0.28 sq in. It is designed for automated workholding systems in machining and assembly operations. The right-hand swing action clears the workpiece area, and the cylinder operates at hydraulic pressures up to 5,000 psi.

What accessories are available for ENERPAC RSL series torque wrenches?

ENERPAC offers extended reaction tubes for the RSL series, such as the ERT19024, which has a 24-inch overall length and a 31 1/2-inch socket center to end dimension. These tubes are compatible with the RSL19000 model and are used to provide reaction support during bolting operations. Other accessories include flat bases and plungers for various cylinder models.

Can I find replacement parts for ENERPAC hydraulic pumps through 3G Electric?

Yes, 3G Electric stocks replacement parts for ENERPAC hydraulic pumps, including rubber washers (part number DA5976108) and plungers (CA13604024). These components are designed to maintain pump performance and seal integrity. Each part is identified by manufacturer part number and is compatible with specific pump models.

What is the difference between ENERPAC ZE4408SB-T and ZU4420MB-G pump units?

The ENERPAC ZE4408SB-T is an Advance-series electric pump with a 3-position control valve, while the ZU4420MB-G is a retract-type pump with a 4-way control valve. Both operate at 10,000 psi and 60 cu in/min flow rate, but the ZU4420MB-G is designed for double-acting cylinders and tools requiring retract functionality. The ZE4408SB-T is suited for single-acting applications.
