Custom Hydraulic Power Unit Quote: Duty, Flow and Cooling Inputs

Blog | September 9th, 2026

Request a custom hydraulic power unit quote in Melbourne with pressure, flow, duty, cooling, controls, space and service-access requirements.

A custom hydraulic power unit quote needs verified pressure, flow, duty, controls, space and environmental inputs. Mobile Hydraulic Specialties designs and installs custom fluid-power systems in Melbourne. We configure the system around the supplied operating requirement rather than assuming that a generic power pack suits every industrial or mobile application.

The previous mining-specific version exceeded the service evidence on our website. Our documented custom hydraulic system services cover mobile and industrial hydraulic and pneumatic applications without promising a specialist solution for every mine site or machine.

Define the Hydraulic Functions First

List each actuator or function, required movement, load, speed and whether functions operate simultaneously. Working pressure and peak pressure are different inputs; so are normal flow and short-duration demand. Available electrical or engine power, voltage, controls and connection requirements must also be stated.

Our hydraulic products and power-unit range includes pumps, valves, filtration, coolers, accumulators and related components. The correct combination depends on the circuit and duty, not a standard parts checklist.

What Information Should the Quote Request Include?

Provide drawings and operating data where available:

  • Pressure and flow: State normal, maximum and peak requirements for each function.
  • Duty cycle: Describe operating duration, idle periods, starts and simultaneous movements.
  • Environment: List ambient temperature, dust, moisture, vibration, noise and enclosure needs.
  • Installation: Show footprint, mounting, hose routes, reservoir limits and power connections.
  • Maintenance: Allow access for filters, gauges, fill points and component removal.

Our published hydraulic power pack design guide discusses reservoir, cooling and noise considerations. Its general examples are not fixed sizing rules for a new system.

Treat Heat and Contamination as Design Inputs

Heat generation depends on losses, duty and ambient conditions. Filtration depends on component requirements, ingression risk and maintenance practice. A larger tank or cooler is not automatically the answer. Provide the operating profile so thermal and cleanliness requirements can be assessed with the circuit.

Safe Work Australia’s plant risk management code explains that risks must be managed across design, installation, use and maintenance. A supplied power unit does not replace machine guarding, functional safety, engineering verification or site commissioning responsibilities.

Our article on hydraulic system design constraints provides related planning context. Mark unknown values honestly so our team can identify what must be measured or decided.

For replacement systems, include the existing circuit drawing, component nameplates, fault history and the reason for change. State which parts of the machine will remain and whether current performance has been measured. Copying an old power unit without understanding altered duty or recurring faults may reproduce the original limitation rather than solve it.

The commercial brief should also identify required documentation, testing, delivery, installation and commissioning boundaries. Clarify who supplies hoses, electrical work, controls integration and final machine verification. This makes competing quotations easier to compare and prevents essential interface work from being hidden outside the stated scope.

Request a Power Unit Scope Review

Use our hydraulic project enquiry page to send the machine function, pressure and flow data, duty cycle, power supply, environmental conditions, space envelope, drawings and timing. We can review the inputs, clarify gaps and define the next quotation step.
