Hydraulic Pullers with Separate Pump

Design and operating principle of hydraulic pullers with separate pump

The system consists of a hydraulic puller (frame with cylinder) and a separate hydraulic pump connected by high-pressure hoses. When the pump is operated, pressure builds up in the cylinder and generates the pulling force via the ram or forcing screw.

Depending on the application, hand pumps, air-driven or electric hydraulic pumps can be used. This allows the set-up to be tailored to the required force, duty cycle and available power source.

Typical applications of pullers with separate pump

Typical applications include:

• removal of large or tight-fitting bearings and hubs
• pulling gears, couplings and pulleys
• overhaul of heavy machinery, drives and rolling equipment
• maintenance work in steel mills, power and process plants
• jobs where the operator should work at a safe distance

Benefits compared to self-contained pullers

• higher available pulling forces and larger working ranges
• flexible positioning of puller and pump
• improved ergonomics and operator safety
• one pump can often supply several cylinders or pullers (system dependent)

Selecting the right hydraulic puller set

When choosing a hydraulic puller with separate pump, consider:

• required pulling force and component size
• whether internal or external pulling is needed, and the grip range
• available power source (manual, air or electric)
• space around the component and desired operator position
