Oil & Lubricant Transfer Pumps
Filter and sort
Piusi's Viscomat range is purpose-built for transferring oils and lubricants that standard diesel vane pumps cannot handle efficiently. These are gear pumps, engineered to move dense, viscous fluids like engine oil, gear oil, hydraulic fluid and general-purpose lubricants at consistent flow rates and medium pressures. Whether you are running a lube service vehicle, a workshop oil dispensing bay, or a mobile maintenance operation, the Viscomat series is the right tool for the job.
Why You Need an Oil-Specific Pump
Standard diesel transfer pumps use vane pump technology optimised for thin, low-viscosity fluids. Trying to pump engine oil or gear oil through a diesel vane pump results in slow flow, excessive strain on the motor, overheating and premature failure. Piusi's Viscomat gear pumps use a positive displacement design with meshing internal gears that handle high-viscosity fluids reliably, delivering consistent flow regardless of oil thickness. The tighter internal tolerances also mean better suction performance when drawing oil from drums, tanks and sumps.
The Piusi Oil Pump Range
Viscomat Self3000 Battery Kit (12V DC) - A portable 12V gear pump kit for mobile oil transfer. 10 lpm flow rate, supplied with battery clips, suction and delivery hose, and drum adaptor. Designed for lube trucks, service vehicles and field maintenance where mains power is not available. Handles engine oils up to SAE 90.
Viscomat 200/2 M (240V AC) - A compact 240V mains-powered gear pump delivering 9 lpm. Suitable for workshop oil dispensing from drums and small bulk tanks. Handles oils up to SAE 90 viscosity. Continuous duty rated for permanent installations.
Viscomat 230/3 Flowmat (240V AC) - The higher-flow option in the range at 14 lpm. Includes an integrated flow control (Flowmat) for smoother dispensing. Handles oils up to SAE 140 viscosity at 20°C, making it suitable for heavier gear oils and hydraulic fluids as well as standard engine oils.
Which Oil Pump Do I Need?
| Application | Recommended Product | Voltage | Flow Rate | Max Viscosity |
|---|---|---|---|---|
| Mobile oil service, lube truck | Viscomat Self3000 Battery Kit | 12V DC | 10 lpm | SAE 90 |
| Workshop drum dispensing | Viscomat 200/2 M | 240V AC | 9 lpm | SAE 90 |
| Higher flow, heavier oils | Viscomat 230/3 Flowmat | 240V AC | 14 lpm | SAE 140 |
Use Cases
Lube Service Vehicles - Mobile mechanics, fleet service operators and mine maintenance crews need to transfer oil in the field. The 12V Viscomat Battery Kit mounts on a ute tray or service truck and runs directly from the vehicle battery. Pump engine oil, transmission fluid or hydraulic oil into machinery without needing a generator or mains power.
Workshop Oil Dispensing - Mechanics, diesel fitters and service centres need clean, reliable oil dispensing from drums or bulk tanks. The 240V Viscomat pumps connect to a standard 205L drum or wall-mounted tank and deliver consistent flow through a dispensing nozzle or oil gun. Pair with a flow meter for accurate volume tracking per job.
Fleet Maintenance Bays - Transport depots, bus operators and heavy vehicle workshops that perform regular oil changes on fleet vehicles. A fixed Viscomat pump installation with a hose reel and dispensing gun streamlines the process and reduces spillage.
Agricultural Machinery Servicing - Farmers and rural contractors servicing tractors, harvesters, irrigators and implements. The 12V battery kit handles oil changes and top-ups in the shed or out in the paddock.
Mining and Resources - Oil transfer for heavy plant maintenance at surface and underground operations. The Viscomat range handles the viscosities commonly used in mining equipment hydraulics and drivetrain systems.
Industrial and Manufacturing - Machine shops, processing plants and manufacturing facilities where oil and lubricant dispensing is part of daily operations.
Oil Pump Basics: Gear Pump vs Vane Pump
| Feature | Gear Pump (Viscomat) | Vane Pump (Diesel pumps) |
|---|---|---|
| Designed for | Oils, lubricants, viscous fluids | Diesel, gasoil, biodiesel |
| Pump mechanism | Meshing gears, positive displacement | Sliding vanes in a rotor |
| Viscosity handling | Up to SAE 140 | Low viscosity only |
| Flow consistency | Steady, pressure-independent | Drops with thicker fluids |
| Typical flow rate | 9 to 14 lpm | 30 to 90+ lpm |
| Best for | Engine oil, gear oil, hydraulic fluid | Diesel transfer and refuelling |
The key takeaway: if the fluid you are pumping is thicker than diesel, you need a gear pump. Trying to save money by using a diesel pump for oil transfer will cost more in the long run when the pump fails.
Important: Oil Pump Care
- Always use a suction strainer or filter when the cleanliness of the oil cannot be guaranteed. Gear pumps have tight internal tolerances, and particles or debris can jam between the gears and damage the pump.
- Do not use oil pumps for water, AdBlue, solvents or fuels. The pump seals and materials are selected for oil compatibility.
- For very cold conditions, oil viscosity increases significantly. Allow the oil to reach a workable temperature before pumping, or select a pump rated for the viscosity at your operating temperature.
- Flush the pump periodically if switching between different oil types.

FAQs - Oil Transfer Pumps
Can I use a diesel pump for oil? No. Diesel pumps use vane pump technology designed for thin, low-viscosity fluids. Pumping oil through a diesel vane pump causes slow flow, motor strain, overheating and premature failure. Use a Viscomat gear pump for oil and lubricant transfer.
What viscosity can Piusi oil pumps handle? The Viscomat Self3000 and Viscomat 200/2 handle oils up to SAE 90. The Viscomat 230/3 Flowmat handles oils up to SAE 140 at 20°C. For heavier oils or lower temperatures, contact our team to confirm suitability.
Can I pump waste oil or used engine oil? The Viscomat pumps can handle used engine oil, but always use a suction strainer to protect the pump from metal particles and debris. Waste oil that contains water, solvents or fuel contamination may not be suitable. Contact our team to discuss your specific application.
What is the difference between the 9 lpm and 14 lpm models? The Viscomat 200/2 M (9 lpm) is the compact option for standard engine oils in lower-volume applications. The Viscomat 230/3 Flowmat (14 lpm) delivers higher flow, handles thicker oils (up to SAE 140) and includes integrated flow control for smoother dispensing. Choose the 230/3 if you are dispensing frequently or working with heavier oils.
Is there a 24V oil pump? Piusi currently offers the Viscomat in 12V DC and 240V AC configurations. There is no 24V DC model in the standard range. For 24V applications (trucks, heavy plant), contact our team on 1300 987 789 to discuss alternative solutions.
Do oil pumps come with a warranty? Yes. All Piusi products sold through PIUSI Shop come with manufacturer warranty support. Contact our team for warranty terms specific to each model.
