Group 1 AC · AC hydraulic power units

For fixed industrial applications on mains power: continuous S1 or intermittent S3 duty.

The Group 1 AC line is Gazzera’s family of 230V single-phase and 400V three-phase hydraulic power packs for fixed industrial applications: S1 continuous or S3 intermittent duty, flows up to ~20 l/min and pressures up to 210 bar. Every unit is configured for your application and 100% tested before shipping.

This is the line for mains-powered machines: machine tools, test benches, stationary compactors, industrial automation. An AC motor in continuous duty withstands long cycles and pressure holding that a DC motor could not, with steady efficiency and minimal maintenance. The architecture is modular: a central manifold with the required valve cavities, a group 1 pump in the exact displacement, and a 3 to 30 litre reservoir in plastic or steel.

Configuration starts from two numbers, pressure from the load and flow from the required speed, and from the real duty cycle, which sets motor size and duty rating. Single-phase or three-phase depends on the supply available at the plant; for special needs (two-speed, soft starting) our technical department proposes the solution at quotation. The configurator in /tools/ gives an instant first answer.

Components compatible with this line

Hydraulic pumps

Gear pumps for compact power packs: a wide displacement range for every flow/pressure combination.

Electric motors

Single/three-phase AC and 12/24V DC motors coupled to the pump via dedicated kits, for continuous or intermittent duty.

Manifolds

Aluminium manifolds for compact power packs, machined to drawing with configurable cavity count.

Modular elements & solenoids

Modular blocks, NG6 solenoid valves, coils and connectors to build the power pack control logic.

Reservoirs

Plastic and steel reservoirs, horizontal and vertical, from 1.5 to 30 litres, with dedicated plugs and accessories.

Suction & return

Suction and return kits matched to the reservoir: strainers, filters and fittings sized to pump flow.

Valves & plugs

Relief, check and lowering valves plus plugs for complete power pack circuit control.

Power pack accessories

Gauges, pressure switches, level indicators, heat exchangers and contactors: everything that completes the power pack.

FAQ

Frequently asked questions

What powers and voltages does the AC line cover?

Single-phase 230V and three-phase 400V motors from 0.25 to 5.5 kW, with group 1 pumps from 0.9 to 9.8 cm³/rev and pressures up to 210 bar. It is the line for mains-powered machines in continuous duty.

Single-phase or three-phase?

It depends on the electrical supply available at the plant. Three-phase is preferable for higher powers and continuous duty; for single-phase we check size and starting torque on the real cycle.

What reservoirs does the AC line use?

From 1.5 to 30 litres, in plastic or steel, horizontal or vertical, with suction and return kits from the same platform.
