How the power pack configurator works: 5 steps to your own unit
With the power pack configurator you build your own hydraulic power unit in 5 steps: you enter the working pressure and flow rate, choose a motor, choose the type of unit, set the pump, tank and valves, and check the result. The configurator calculates the power you need straight away with P (kW) = p (bar) × Q (l/min) / 540. Example: for 150 bar and 5 l/min that is 150 × 5 / 540 = 1.4 kW.
Step 1: enter working pressure, flow rate or power
Enter the working pressure in bar and the flow rate you need in litres per minute. The configurator then calculates the power you need in kW. If you already know the power, you can enter it directly. If you have configured a unit before, you can open it again with the product code of your configuration.
Step 2: choose the motor
You will see the motors that match your figures, grouped into electric 12/24 V (DC, including 48 V), electric 230/400 V (AC), petrol and diesel. You can also choose a motor directly without calculating first.
Step 3: choose the type of unit
Choose the type that suits the motor and your application, for example a Mini Powerpack, a Workshop unit, a Motor+pump combination or an Industrial unit with an open or closed frame. You will see which types are available after choosing the motor.
Step 4: set the pump, tank, pressure relief and valves
The configurator suggests a suitable pump and tank. You can change the pump displacement (cc), the tank and the pressure relief setting yourself. Choose whether the circuit is single acting or double acting, and add valves if needed. For single acting you choose a lowering valve (12, 24, 48 or 230 V, normally closed or normally open, or manual) and, if you like, return throttling. You can add a support, a pressure gauge and a water-absorbent tank breather.
Step 5: check, download and order
On the left you see the calculated flow rate, the maximum pressure and the pressure relief setting, together with the motor data. You can download the hydraulic schematic with specifications, a 3D file and the manual (Dutch and English), view the dimensions and create a link to your configuration with the Share button. Then you add the unit to your cart.
Calculating your power pack
| What | Formula | Example from the configurator |
|---|---|---|
| Required power | P (kW) = p (bar) × Q (l/min) / 540 | 150 bar × 5 l/min / 540 = 1.4 kW |
| Pump flow rate | Q (l/min) = displacement (cc) × speed (rpm) / 1000 | 3.2 cc × 1,500 / 1000 = 4.8 l/min |
| Maximum pressure for a motor | p (bar) = P (kW) × 540 / Q (l/min) | 1.5 kW × 540 / 4.8 l/min = 168.75 bar |
Which motor suits your application?
| Motor | When to choose it |
|---|---|
| Electric 12/24 V (DC, including 48 V) | Mobile applications running on a battery, for example on a trailer, vehicle or boat. |
| Electric 230/400 V (AC) | Fixed installations with mains power, for example in a workshop or machine. |
| Petrol | Mobile work without a power supply. |
| Diesel | Mobile work without a power supply, often for higher power. |
Frequently asked questions
How do I calculate how much power my power pack needs?
Multiply the working pressure (bar) by the flow rate (l/min) and divide by 540; the factor comes from 600 × 90% efficiency. Example: 150 bar × 5 l/min / 540 = 1.4 kW.
How do I calculate the pump flow rate?
Multiply the pump displacement (cc) by the motor speed (rpm) and divide by 1000. A 3.2 cc pump at 1,500 rpm delivers 4.8 l/min.
What is the difference between single acting and double acting?
In a single acting circuit the oil pushes the cylinder in one direction and it returns under the load or a spring; for this you choose a lowering valve in the configurator. In a double acting circuit the oil moves the cylinder in both directions.
Can I find a previous configuration again?
Yes. Enter the product code of your configuration in step 1, or use the link you created with the Share button.
What if my power pack does not fit the configurator?
Then we build it to order. Read more under Custom hydraulics, or contact us.
Go to the power pack configurator. You will find all ready-made units under Power packs. Read what happens after you order in Building a custom power pack.
