The range of hydraulic wrenches (operated at a maximum working pressure of 700 bar) covers extreme performance ranges up to 100,000 Nm. These tools are primarily used in the wind power sector, pipeline construction, refineries, and heavy machinery manufacturing.

Emava's hydraulic portfolio is divided into three distinctive main series:

1. TU Series (Square Drive Hydraulic Wrenches) The Emava TU series is the established, universal powerhouse for classic use with impact wrench sockets. Performance range: From smaller models to extreme tools up to 100,000 Nm. Material & Housing: Made from a high-strength aluminum-titanium alloy for minimal weight under maximum load. Technology: A patented "Never-Lock" system prevents the tool from jamming on the bolt under full load. The "Uni-Swivel" joint allows 360° × 180° hose rotation.

2. TX Series (Cassette Screwdrivers / Low-Profile) The Emava TX series is designed to be flat and compact (low-profile design) for direct mounting on the tightest flange connections. Power is transmitted via interchangeable hexagonal cassettes. Model Overview & Performance: TX-1: Compact model for tight spaces up to 800 Nm (wrench sizes 19–41 mm). TX-2: All-rounder up to 3,000 Nm (wrench sizes 19–65 mm). TX-8: Heavy-duty cassette up to 12,000 Nm for large flanges. TX-45: Top-of-the-line model in the series up to 65,000 Nm (wrench sizes up to 195 mm). Special Feature: The patented piston-shaped housing design ("peanut shape") eliminates the need for external support arms, as the flat cylinder back can rest directly against the adjacent bolt.

3. SQ Series (Ergonomic Square Drive Screwdrivers) The SQ series from Emava represents the modernized further development of classic square drive screwdrivers. Performance range: Models range from the SQ-1 (1,900 Nm) to the SQ-10 (16,200 Nm). Design advantages: A flat housing base allows the tool to be placed directly against the ground without an additional support foot. The housing also offers versatile mounting points for ergonomic handles. Required system accessories: The SPEED pump hydraulic screwdrivers do not operate independently but require a drive unit.

Emava distributes the three-stage SPEED hydraulic pumps (SPE series) for this purpose. Thanks to the Quadra-Torc connection block, up to four hydraulic wrenches can be connected simultaneously to tighten flanges evenly and crosswise without distortion.
