FAST FILL PRESSURELESS DIRECT MOUNT REFUELLING SYSTEM

Components, Operation & Applications

Fast Fill Systems USA | Distributed by Silveri Engineering & Trading Pty Ltd

Product Overview

The Fast Fill Pressureless Direct Mount Refuelling System is engineered to provide safe, efficient and reliable high-volume diesel refuelling for mining, construction and heavy industrial equipment fitted with non-pressurised fuel tanks.

Unlike conventional pressurised fast-fill systems, the pressureless direct mount arrangement enables automatic fuel shut-off without requiring the fuel tank to be pressurised.

The system incorporates a directly mounted diesel receiver, pressureless shut-off assembly, fuel-level controller and filtered tank vent to manage fuel delivery and automatically terminate refuelling when the predetermined fuel level is reached.

The direct mount configuration offers a compact installation with fewer external fuel connections and reduced plumbing requirements compared with remote-mounted systems.

Key Features & Benefits

• Direct Mount Configuration: The receiver and shut-off assembly are mounted together, providing a compact and efficient refuelling arrangement.
• Automatic Fuel Shut-off: Terminates diesel delivery when the predetermined fuel level is reached.
• Non-Pressurised Operation: Designed for atmospheric fuel tanks without relying on tank pressurisation to activate shut-off.
• High-Flow Performance: Selected configurations support diesel refuelling rates up to 800 L/min, subject to component ratings and installation conditions.
• Heavy-Duty Construction: Engineered for demanding mining and industrial operating environments.
• Reduced Plumbing Requirements: Minimises the need for extended fuel hoses and multiple fittings.
• Reduced Risk of Overfilling: Automatic shut-off helps minimise diesel spills and fuel wastage.
• Simplified Maintenance: Direct access to the receiver and shut-off assembly assists inspection and servicing.

Main System Components

Component	Typical Part Number	Function
Pressureless Direct Mount Assembly	PLA150-M series	Main pressureless diesel filling and automatic shut-off assembly
Vent Level Controller	PLA150-M-VLCE	Detects the predetermined fuel level and initiates shut-off
Filtered Fuel Vent	FFV150-PL	Provides filtered atmospheric tank ventilation
Fast Fill Receiver	R150SC series	Provides a connection for the compatible Fast Fill refuelling nozzle
Signal Line	PL-P-6, where applicable	Transfers the shut-off control signal between components
Mounting Adaptor & Seals	Application-specific	Provides a secure connection between the assembly and fuel tank

Part numbers and component combinations must be confirmed against the selected direct mount configuration.

Technical & Installation Considerations

Correct installation is essential to ensure reliable operation and effective automatic fuel shut-off.

• Direct Mount Position: The receiver and shut-off assembly should be mounted as close to the tank inlet as practical.
• Fuel Line Routing: Avoid unnecessarily long pipework, sharp bends and restrictive fittings that may affect flow and shut-off performance.
• Tank Ventilation: The filtered vent must be correctly sized to accommodate displaced air during high-volume refuelling.
• Fuel Tank Clearance: Allow adequate internal and external clearance for the level controller and shut-off components.
• Fuel Level Setting: Maintain sufficient ullage to accommodate fuel expansion and prevent overfilling.
• Mounting Integrity: All connections must be mechanically supported and correctly sealed to prevent leakage and vibration-related damage.
• Component Compatibility: Receivers, nozzles and shut-off assemblies must be compatible and rated for the intended operating conditions.

Important: Maximum flow rate, allowable pipe length, mounting dimensions and installation clearances depend on the specific pressureless assembly and tank arrangement. These should be verified against the manufacturer’s installation instructions before commissioning.

Typical Applications

The Fast Fill Pressureless Direct Mount System is suitable for appropriately configured:

• Mining haul trucks and wheel loaders
• Hydraulic excavators and bulldozers
• Underground mining machinery
• Construction and earthmoving equipment
• Industrial diesel-powered machinery
• Stationary diesel storage and equipment tanks
