Hydraulic power packs

The right power pack comes from 6 choices: pressure, flow, motor, voltage, reservoir and valves. Here are the components — and the guides to combine them correctly.

A hydraulic power pack is the group that generates a machine’s hydraulic power: an electric motor drives a gear pump pushing oil from the reservoir to the cylinders, while valves on the manifold govern pressure and movements. Gazzera has designed and built them to specification in Italy for 36 years: 8,500 units a year, each one tested before shipping.

How a hydraulic power pack works

The principle is the same from a 0.25 kW micro unit to an industrial power unit: the motor spins the pump, the pump generates flow, the load generates pressure, and the valves decide where the oil goes and at what maximum pressure. The difference between any power pack and the right power pack is sizing: motor chosen on the real duty cycle (S1 continuous or S3 intermittent), pump on the operating speed, reservoir on cylinder volume, valves on the machine’s actual functions.

How much does a hydraulic power pack cost?

It depends on six factors: motor, pump, reservoir, valves, quantity and customisation. A standard compact configuration starts indicatively from a few hundred euros; custom multi-function configurations can exceed a thousand. Our dedicated guide explains transparently what moves the price — and what actually saves money.  Read the price-factors guide →
