240V Diesel Pump Guide: Panther, Cube and ST Box Setups for Fixed Tanks

Choosing a 240V diesel pump for a fixed tank installation sounds straightforward until you start comparing flow rates, duty cycles, and cabinet options across the Panther, Cube and ST Box ranges. Each of these PIUSI setups solves a slightly different problem, and picking the wrong one usually means either paying for capacity you don't need or running a pump harder than its duty cycle allows.

This guide breaks down the practical differences between Panther bare pumps, Cube complete kits, and ST Box lockable cabinet units. You'll walk away knowing which flow rate suits your fleet size, how duty cycle affects continuous refuelling, and how these pumps fit into a full fixed-tank setup alongside meters, nozzles, and PETRO Industrial self-bunded tanks.

If you're refuelling from a fixed diesel tank on a mine site, farm, depot, or workshop, the 240V diesel pump you select determines how fast vehicles turn around and how much manual handling your team does every day.

Choosing Between Panther, Cube and ST Box: What Actually Changes at 240V

The core decision isn't really about brand, it's about how much infrastructure you need bundled with the pump. The PIUSI Panther 56 View Product is a self-priming rotary vane pump rated at 56 L/min, sold as a bare unit. It suits sites that already have a meter, nozzle, and hose reel installed and just need pump replacement or a second dispensing point.

The Cube range takes a different approach. The PIUSI Cube 70/33 View Product ships as a wall-mountable kit with the pump, a K33 mechanical meter, 4 metres of delivery hose, and an A60 automatic nozzle already fitted. It's designed for sites that want a dispensing point up and running without sourcing individual components. The larger PIUSI Cube 90/44 View Product steps flow up to 90 L/min with a K44 meter and A120 nozzle for higher-throughput fleets.

The ST Box goes further again. The PIUSI ST Box 85 L/min View Product puts an E120 pump, water filter, K33 meter, 8 metre hose, and A120 nozzle inside a lockable weatherproof cabinet. That cabinet matters on exposed sites: it protects the components from dust, rain, and unauthorised access, which is why it's the standard choice for standalone fixed-tank installs where there's no shed or bowser canopy nearby.

Key Specs That Separate These 240V Diesel Pump Setups

Flow rate gets most of the attention, but duty cycle and included componentry decide whether a unit fits your refuelling pattern. A pump rated at 90 L/min that can only run 30 minutes continuously won't necessarily outperform a 56 L/min unit rated for longer cycles if you're fuelling multiple vehicles back to back.

Seal material and filtration also matter for fixed-tank use, where tanks accumulate more sediment and condensation over time than portable drums. The ST Box's built-in water filter is a direct response to that reality, and it's worth pairing any of these pumps with a PIUSI 10-micron particulate filter View Product if it isn't already included.

Notice the jump from Cube-tier flow rates into the ST200 and E300. Those higher-flow units aren't really dispensing pumps for individual vehicles, they're bulk transfer pumps for moving diesel between tanks or loading multiple bowsers from a central fixed tank.

Matching the Setup to Your Site: Industry Use Cases

Agricultural operations running a handful of tractors and utes off a farm tank generally get the most value from a Cube 70/33 or Panther 56. Flow rate demands are modest, and the wall-mount Cube kit keeps installation simple against a shed wall near the tank.

Construction and civil sites tend to lean towards the ST Box. Sites change layout, equipment gets moved, and a lockable cabinet protects the pump, meter, and nozzle from both weather and site traffic. The 8 metre hose on the ST Box 85 also gives more reach across uneven ground than the 4 metre hoses on the Cube kits.

Fleet transport depots and workshops with dozens of vehicles refuelling daily benefit from higher continuous duty cycles. This is where the Panther 72 or Cube 90/44 earn their keep, particularly when paired with a pulse meter feeding data into an iPETRO fuel management system View Product for usage tracking across the fleet.

Mining and power generation sites moving large diesel volumes between fixed tanks, generators, or site bowsers are the natural fit for the ST200 or E300. At 550 L/min, the E300 is built for bulk transfer rather than nozzle dispensing, and it's typically installed with larger-bore hose and heavier-duty fittings to match.

Building a Complete Fixed-Tank Refuelling Station

A 240V diesel pump is only one part of a compliant, efficient fixed-tank setup. Pairing it correctly with metering, filtration, and tank monitoring is what actually determines uptime and fuel accountability on site.

For metering, mechanical options like the PIUSI K33 View Product suit straightforward dispensing, while pulse meters feed digital data into fluid management systems for sites tracking litres per vehicle or per job. You can browse the full range of flow meters to match meter type to your reporting needs.

Filtration protects the pump and downstream engines from sediment and water ingress, which is a genuine risk in fixed tanks exposed to temperature swings and condensation. The Clear Captor water filter View Product is worth adding to any fixed installation, and it's worth reviewing the full range of filters available for diesel and AdBlue lines.

On the tank side, PETRO Industrial self-bunded tanks are the natural pairing for these pump setups, offering AS1940-compliant secondary containment with pump mounting points already built in. Add an iPETRO Solus View Product tank gauge and you've got real-time level monitoring alongside your dispensing point, removing the guesswork around reordering fuel. For sites wanting the full picture, browse the full range of fuel monitoring systems to see how gauges and FMS units connect together.

Nozzle choice rounds out the setup. Automatic shut-off nozzles like the PIUSI A120 View Product prevent overfilling and reduce spillage risk, and they're standard fitment on both the Cube 90/44 and ST Box kits. You can also compare options across the nozzles collection if you're upgrading an existing bare pump installation.

What to Buy

If you're replacing a pump on an existing fixed-tank install with meter and nozzle already in place, the Panther 56 View Product or Panther 72 View Product covers straightforward swap-outs.

For a new wall-mounted dispensing point on a farm, workshop, or depot, the Cube 70/33 View Product or Cube 90/44 View Product gets you dispensing without sourcing separate parts.

For an exposed, standalone fixed tank needing weatherproofing and security, the ST Box 85 View Product is the standard choice.

For bulk transfer between tanks or high-volume fleet operations, step up to the ST200 View Product or E300 View Product. Any of these pumps pair naturally with a PETRO Industrial self-bunded tank for a compliant, complete fixed-tank refuelling station. You can also browse the full range of PIUSI diesel pumps to compare every option side by side.

FAQ

What flow rate 240V diesel pump do I need for a small fleet?

A fleet of under 10 vehicles typically runs well on a 56-70 L/min pump such as the Panther 56 or Cube 70/33. Larger fleets refuelling multiple vehicles back to back should look at the 90 L/min Cube or ST Box options.

Can I install an ST Box outdoors without additional shelter?

Yes. The ST Box's lockable cabinet is designed for standalone outdoor installation, housing the pump, meter, filter, and nozzle in a weatherproof enclosure without needing a shed or canopy.

What's the difference between the Cube and ST Box kits?

The Cube kits are wall-mounted units without a cabinet, suited to sites with existing shelter. The ST Box adds a lockable, weatherproof cabinet plus a built-in water filter, making it the standard choice for exposed, standalone fixed-tank installs.

Do these pumps work with AS1940-compliant self-bunded tanks?

Yes. Panther, Cube, and ST Box pumps are commonly installed on PETRO Industrial self-bunded tanks, with mounting points designed to suit fixed-tank installations under AS1940.

Should I add a filter to a 240V diesel pump on a fixed tank?

Fixed tanks accumulate more sediment and moisture over time than portable drums, so adding a 10-micron particulate filter or water filter such as the Clear Captor is recommended for any fixed-tank pump installation, including bare Panther units without one already fitted.
