Jargon Buster

• Automatic Nozzle: A dispensing nozzle that automatically shuts off when the container is full, preventing overflow and spillage. Particularly useful for fuel dispensing applications where unattended filling is required.
• Gravity Feed: A dispensing system that relies on gravity rather than pumping action to transfer fluid from an elevated container. Simple and reliable for workshop oil changes and fluid transfers.
• Flow Control Valve: An adjustable mechanism that regulates the rate at which fluid is dispensed, allowing operators to match flow speed to the application requirements.
• Hose-End Gun: A dispensing gun designed to attach to the end of a flexible hose, typically used with bulk fluid containers or drum pumps for reaching awkward filling points.
• Manual Nozzle: A basic dispensing nozzle requiring the operator to manually control flow by holding the trigger or lever open. Simple, cost-effective and suitable for controlled dispensing applications.
• Swivel Inlet: A rotating connection point that prevents hose twisting and allows easier manoeuvring of the dispensing gun during use, particularly valuable when working in confined spaces.

How to Choose the Right Dispensing Guns

Selecting the appropriate dispensing gun depends on several key factors related to your specific application:

Fluid Type: Ensure the dispensing gun is compatible with the fluids you'll be handling. Different materials are required for petrol, diesel, oils and chemicals. Check whether the gun is suitable for leaded or unleaded petrol if dispensing fuel, and verify chemical resistance for specialist fluids.

Manual vs Automatic Operation: Manual nozzles offer precise control and are ideal for measured dispensing in workshop environments. Automatic nozzles shut off when containers are full, perfect for unattended refuelling of vehicles and machinery where overflow prevention is critical.

Flow Rate Requirements: Consider the volume of fluid you typically dispense. High-flow applications like vehicle refuelling benefit from larger bore nozzles, whilst precision topping-up requires fine flow control. Look for adjustable flow control valves if you need versatility.

Dispensing Method: Gravity-fed systems are simple and reliable for workshop oil changes, requiring no pumping mechanism. Pump-operated and trigger-action guns offer portability and controlled dispensing from containers at any height. Hose-end guns work with separate drum pumps for bulk fluid handling.

Construction Quality: Brass construction offers excellent durability and chemical resistance, making it ideal for professional environments. Heavy-duty models with reinforced components withstand the rigours of daily workshop use and site work.

Ergonomics and Handling: For frequent use, consider guns with comfortable grips, swivel inlets to prevent hose twisting, and balanced weight distribution. Trigger-operated models should have smooth action to reduce hand fatigue during extended dispensing sessions.

Safety Information

Dispensing flammable and hazardous fluids requires strict adherence to safety protocols to protect both operators and premises:

Fire Prevention: Always use dispensing guns in well-ventilated areas away from ignition sources, naked flames and sparks. Ensure electrical equipment is switched off when dispensing petrol or other flammable liquids. Keep appropriate fire extinguishers readily accessible in fuel dispensing areas.

Personal Protective Equipment: Wear appropriate PPE including chemical-resistant gloves, safety glasses and protective clothing when handling oils, fuels and chemicals. Ensure good ventilation or use respiratory protection when working with volatile fluids in enclosed spaces.

COSHH Compliance: Follow Control of Substances Hazardous to Health (COSHH) regulations when handling petroleum products and chemicals. Maintain safety data sheets for all fluids and ensure proper training for all personnel operating dispensing equipment.

Spill Prevention and Management: Use drip trays and absorbent materials to contain spills. Have spill kits available and know proper cleanup procedures for different fluid types. Dispose of contaminated materials according to UK environmental regulations.

Equipment Maintenance: Regularly inspect dispensing guns, hoses and connections for wear, damage or leaks. Replace worn seals and components promptly to prevent drips and failures. Ensure automatic shut-off mechanisms are functioning correctly to prevent overflows.

Static Electricity: When dispensing fuel, ensure proper earthing and bonding procedures are followed to prevent static discharge. Use only approved equipment in potentially explosive atmospheres as required by HSE guidelines.

Frequently Asked Questions

Can I use the same dispensing gun for different types of fluids?

It's best to dedicate dispensing guns to specific fluid types to prevent cross-contamination. Petrol and diesel guns should be kept separate, and oils should not be mixed with fuels. If you must use one gun for multiple fluids, ensure thorough cleaning between different substances and verify the gun's material compatibility with all fluids you intend to dispense.

What's the difference between manual and automatic dispensing nozzles?

Manual nozzles require the operator to hold the trigger throughout dispensing, providing precise control over flow. Automatic nozzles feature a shut-off mechanism that stops flow when the container is full, allowing hands-free operation. Automatic nozzles are ideal for vehicle refuelling, whilst manual nozzles excel at measured dispensing and topping-up applications where exact quantities matter.

Are gravity-fed dispensing systems suitable for professional workshop use?

Absolutely. Gravity-fed systems are widely used in professional garages and workshops for oil changes and fluid transfers. They're simple, reliable and require no pumping mechanism, making them cost-effective and virtually maintenance-free. For best results, ensure the source container is positioned high enough to provide adequate flow pressure.

How do I maintain my dispensing gun to ensure long service life?

Regular maintenance includes cleaning the nozzle after each use to prevent fluid build-up, checking and replacing worn seals, and inspecting hoses for cracks or deterioration. Store guns in a clean, dry location when not in use. For automatic nozzles, periodically test the shut-off mechanism to ensure it's functioning correctly. Replace any components showing signs of wear or damage promptly.

Can I use a dispensing gun with any drum pump or fluid container?

Most dispensing guns with standard hose connections will work with compatible pumps and containers, but always verify thread sizes and connection types match. Some dispensing guns come as complete kits with matched hoses and fittings. For gravity-fed systems, ensure your container has the appropriate outlet size and positioning. Check the gun's specifications for maximum operating pressure if using with pumped systems.
