Applications
What Is a Fluid Transfer Pump Used For?
Fluid transfer pumps are used wherever a liquid needs to be moved from one container, tank or system to another — with control, accuracy and safety. Across Australian industry, the most common applications span fuel handling, lubrication systems, hydraulic servicing, chemical dispensing and general liquid transfer.
Diesel & Fuel Transfer
Moving diesel from storage tanks to vehicles, machinery and generators — the most common fluid transfer application across mining, agriculture, construction and transport.
Oil & Lubricant Dispensing
Controlled dispensing of engine oil, hydraulic oil, gear oil and lubricants from bulk containers to machinery — in workshops, service bays and field service vehicles.
Hydraulic System Servicing
Draining and filling hydraulic systems on machinery and equipment — using pumps with appropriate pressure ratings and fluid compatibility for hydraulic fluid.
Chemical Transfer
Moving agricultural chemicals, fertilisers, cleaning solutions and industrial chemicals between containers — requires chemical-compatible pump materials specific to each fluid.
Water Transfer
Moving water between tanks, filling systems and washdown applications — centrifugal and diaphragm pumps suited to high-volume water transfer in agricultural and civil applications.
Drum & IBC Emptying
Pumping from 200L drums and IBCs — barrel pumps, drum pumps and rotary hand pumps for decanting oils, chemicals, solvents and viscous liquids from bulk containers.
Pump Types
Types of Fluid Transfer Pump — Choosing the Right Technology
Different pump technologies are suited to different fluids and applications. Understanding which pump type matches your fluid's viscosity, your required flow rate and your power source is the foundation of correct pump selection.
Low Viscosity Fluids
Vane Pump
Rotating slotted rotor with sliding vanes — the most common technology for diesel, kerosene and light lubricant transfer. Good flow rates at moderate pressures. Self-priming. Used in 12V, 24V and 240V diesel transfer pumps.
High Viscosity Fluids
Gear Pump
Meshing gear set moves fluid between tooth cavities — handles high-viscosity oils, hydraulic fluid and lubricants effectively at consistent flow and higher pressures. The standard technology for oil dispensing and lubrication systems.
Versatile — Multi-Fluid
Diaphragm Pump
Flexible diaphragm displaces fluid without rotating seals — suited to viscous, abrasive, corrosive and shear-sensitive fluids. Available in air-operated (AODD) versions for hazardous area and chemical applications. Self-priming, can run dry.
High Volume — Water & Fuel
Centrifugal Pump
Rotating impeller generates centrifugal force — high flow rates for low-viscosity fluids including water, diesel and thin oils. Not self-priming — requires a flooded inlet or external priming. Suited to fixed high-volume transfer applications.
Drum & IBC Decanting
Barrel / Drum Pump
Submersible tube pump inserted directly into drums and IBCs — available in manual, electric and pneumatic versions for oils, chemicals, solvents and viscous liquids. Compact, portable and easy to clean between fluids.
Manual & Low Volume
Rotary Hand Pump
No power source required — hand-operated rotary or lever action for low-volume fuel, oil and chemical transfer from drums and tanks. Ideal for remote areas, backup use or where power is unavailable.

Buying Guide
How to Select the Right Fluid Transfer Pump
Correct pump selection prevents equipment damage, ensures safe fluid handling and delivers the flow rate and pressure your application needs. Work through these five factors before making a purchase — or call A-FLO to get a recommendation based on your specific fluid, site and throughput requirements.
01
Identify the Fluid — and Confirm Chemical Compatibility
The fluid being transferred determines everything — pump type, seal material, body construction and hose specification. Diesel and oil pumps are not interchangeable with chemical or corrosive fluid pumps. Confirm that the pump's wetted materials (seals, body, impeller) are compatible with your specific fluid before purchase. Incorrect material selection causes rapid seal failure, contamination and potential safety incidents.
02
Check Viscosity — It Determines Pump Technology
Viscosity is the single most important technical factor in pump selection. Low-viscosity fluids (diesel, water, thin lubricants) — centrifugal or vane pumps. Medium-viscosity fluids (engine oil, gear oil, hydraulic fluid) — gear or diaphragm pumps. High-viscosity fluids (heavy oils, adhesives, viscous chemicals) — gear, progressive cavity or piston pumps. Using the wrong pump technology for a high-viscosity fluid causes overloading, poor flow and premature failure.
03
Determine Flow Rate and Outlet Pressure
Flow rate (litres per minute) determines how quickly the transfer is completed — and must be matched to your throughput requirement. Outlet pressure (bar or PSI) determines whether the pump can overcome pipe friction losses, hose length and any height difference between the pump and the delivery point. Selecting a pump with insufficient pressure will result in reduced flow or inability to deliver to height.
04
Match the Power Source to Your Site
Manual / hand pumps — no power required, low flow, portable. 12V DC — vehicle battery powered, ideal for mobile and field use. 24V DC — heavy vehicle powered applications. 240V AC — mains powered, higher flow rates, fixed depot and workshop. Air-operated — compressed air powered, required for hazardous areas, no electrical ignition risk. Engine-driven — fully off-grid, high flow for remote high-volume applications.
05
Choose Fixed or Portable Mounting
For mobile applications — portable drum pumps, 12V DC barrel pumps, trolley-mounted transfer units and trailer-mounted configurations. For fixed installations — wall-mounted dispensing units, tank-mounted pumps on self-bunded diesel or oil tanks, and workshop lube bay systems with overhead hose reels. The mounting configuration affects hose length, reel requirements and access control options.
Maintenance Guide
Fluid Transfer Pump Maintenance Requirements
Regular maintenance extends the service life of your fluid transfer pump, maintains flow rate and pressure performance, and prevents leaks or contamination incidents that create safety and compliance risks. Build these tasks into your scheduled maintenance program and document them for compliance records.
Inspect Hoses & Fittings
Check suction and delivery hoses, camlock fittings and hose clamps for cracks, swelling, wear or loose connections — before first use each day in high-demand applications.
Clean & Replace Filters
Inspect and clean inlet strainers regularly — replace fuel and oil filters on schedule. A blocked filter restricts flow, increases pump load and allows contaminants to reach downstream equipment.
Lubricate Moving Parts
For pumps with external bearings, gears or drive shafts — apply the manufacturer-specified lubricant at scheduled intervals. Do not over-lubricate as this can cause seal damage or attract contaminants.
Inspect Seals & Gaskets
Check shaft seals, body gaskets and O-rings for deterioration, hardening or swelling — signs of chemical incompatibility or end of service life. Replace before leaks develop rather than after.
Monitor Flow & Pressure
A drop in flow rate or outlet pressure signals internal wear, a partially blocked strainer or a developing seal leak. Address performance drops early before they escalate to pump failure.
Flush Between Fluids
When switching between fluid types or after handling corrosive or reactive liquids — flush the pump thoroughly with a compatible flushing fluid before storing or using with a different product. Cross-contamination can damage the pump and the downstream equipment or fluid.
Check Power Connections
Inspect electrical connections, cable insulation and terminal crimps for corrosion, loose connections or chafing — particularly on mobile units subject to vibration. For 240V installations, have a licensed electrician inspect connections at the scheduled service interval.
Follow Manufacturer Guidelines
Each pump model has specific maintenance procedures, service intervals and spare parts — follow the user manual for your specific pump and keep a maintenance log for compliance and warranty purposes.
Why maintenance matters for fluid transfer pumps
- Optimal performance — correct flow rate and pressure maintained across the service life of the pump
- Operational safety — prevents leaks, spills and contamination incidents that create WHS and environmental liability
- Regulatory compliance — particularly important in mining, chemical handling and fuel transfer where strict standards apply
- Cost-effective operation — routine maintenance prevents premature failure and costly unplanned replacement of pump and downstream equipment
Frequently Asked Questions
Fluid Transfer Pump FAQ
What is the difference between a gear pump and a vane pump?
A gear pump uses meshing gears to displace fluid — it handles high-viscosity fluids like engine oil, hydraulic oil and lubricants effectively and delivers consistent flow at higher pressures. A vane pump uses a rotating slotted rotor with sliding vanes — better suited to lower-viscosity fluids like diesel, kerosene and light lubricants, typically delivering higher flow rates at lower pressures. For diesel transfer, vane pumps are the standard choice. For oil dispensing and lubrication systems, gear pumps are preferred.
Can I use a fluid transfer pump for chemicals and corrosive liquids?
Some fluid transfer pumps are specifically designed for chemical and corrosive liquid handling — but standard diesel or oil pumps are not. Chemical-compatible pumps use construction materials such as stainless steel, PVDF, polypropylene or PTFE-lined wetted components that resist corrosion and chemical attack. Never use a standard diesel or oil pump with chemicals or corrosives — incorrect material selection causes rapid seal failure and potential contamination or safety incidents. A-FLO can advise on the correct pump specification for your fluid — call 1300 235 623.
What is an air-operated double diaphragm (AODD) pump and when should I use one?
An AODD pump uses compressed air to alternately flex two diaphragms — creating a reciprocating pumping action with no rotating electrical components. AODD pumps are the preferred choice for hazardous area applications where electrical ignition risk must be eliminated, for corrosive and aggressive chemicals where chemical-grade materials are needed, and for shear-sensitive or abrasive fluids that would damage rotating pump elements. They are self-priming, can run dry without damage and handle viscous or particulate-laden fluids.
Do fluid transfer pumps require a flow meter?
A flow meter is not required for every fluid transfer application — but it is strongly recommended wherever accurate volume tracking is needed for cost allocation, billing, compliance or inventory control. For diesel and fuel transfer, a digital flow meter with resettable batch counter is standard in professional setups. For oil dispensing in workshops, a meter enables accurate records of lubricant usage per vehicle or service. A-FLO supplies digital flow meters compatible with diesel, oil and other fluid transfer pump setups.
