Group 1 DC · 12V/24V hydraulic power units

For mobile equipment and 12/24V battery applications: lifting, tippers, platforms.

The Group 1 DC line is Gazzera’s family of 12V and 24V hydraulic power packs (12v hydraulic power units) for mobile equipment and battery applications: dump bodies, liftgates, platforms, vehicle equipment. S3 intermittent-duty DC motors from 0.5 to 3 kW, flows up to ~20 l/min, pressures up to 210 bar, single or double acting units, 100% tested.

This is the line for on-vehicle work: the DC motor delivers the strong starting torque needed to lift immediately, a contactor sized on real currents switches it safely, and the circuit follows the equipment’s function (single acting with gravity lowering, or double acting with a solenoid valve). Reservoirs from 4 to 25 litres, made to measure when chassis-to-body space demands it; pendant pushbutton or radio control.

The 12V vs 24V choice is almost always made by the vehicle (our dedicated guide explains when each pays off); the pump choice is made by the desired operation time. Mind the cycle: DC motors work in bursts with cooling pauses, so if the application demands long or frequent operations, sizing must respect the real intermittence ratio, which is exactly what we do in every quotation.

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.

Connection elements

Adapter flanges and couplings, motor side and pump side, that join the electric motor to the pump: guaranteed alignment, complete ready-to-fit kit.

FAQ

Frequently asked questions

What is the Group 1 DC line for?

Running hydraulics on board a vehicle at 12V or 24V: dump bodies, liftgates, platforms. S3 intermittent-duty DC motors from 0.5 to 3 kW, pressures up to 210 bar.

12V or 24V?

The vehicle’s electrical system almost always decides. At equal power, 24V draws half the current, so lighter wiring and contactors; our dedicated guide explains when each pays off.

Single or double acting?

Single acting lifts and lowers by gravity (typical of a dump body); double acting drives both directions with a solenoid valve (liftgates, snow plows). The circuit follows the equipment’s function.
