Description

RAASM 1:1 Ratio Oil Pump is one of the best Ratio Pumps available in the Australian Market. Built with corrosion-resistant materials, RAASM 1:1 Ratio Oil Pumps can be used to transfer various different types of liquids such as oil, diesel, etc.

The RAASM 1:1 Ratio Drum Pump is designed for transferring low viscosity liquids relatively short distances at low pressures. These Drum Pumps are ideal for mounting drums and servicing oil bars. For heavier gear oils and longer distances or for servicing hose reels, higher pressure pumps should be used.

What does a 1:1 Ratio mean?
The pumping ratio, as explained by the Petroleum Equipment Institute (PEI), is the area of the air piston compared to the area of the fluid piston in an air-powered pump. \n \nSo when we have a 1:1 ratio, it means that the amount of air-input pressure is equal to that of the fluid-output pressure. For example, if the pump has 100 PSI of air going in then, there will be 100 PSI of pressure pushing the fluid out.

Oil Transfer Pump

What is an oil transfer pump used for?

An oil transfer pump is designed to move oil and other lubricants efficiently from one container or system to another. These pumps are commonly used in automotive, industrial, agricultural, and marine settings to handle tasks like refuelling equipment, changing engine oil, or transferring hydraulic fluids.

Oil transfer pumps can be manual, electric, or pneumatic, and are compatible with a wide range of oils—including motor oil, gear oil, hydraulic oil, and transmission fluid. By ensuring safe and spill-free fluid handling, they improve efficiency and reduce contamination risks during maintenance operations.

How do I choose the right oil transfer pump?

Choosing the right oil transfer pump depends on several key factors:

  • Fluid Type & Viscosity: Make sure the pump is compatible with the specific type of oil (e.g., synthetic, mineral, or gear oil) and can handle its viscosity.
  • Flow Rate: Look for a pump with the correct flow rate (litres per minute) based on how quickly you need to transfer the fluid.
  • Power Source: Select between manual, electric (12V, 240V), or pneumatic (air-operated) depending on your environment and power availability.
  • Pump Material: Ensure the pump's components are resistant to the chemical properties of the oil being handled.
  • Portability: Consider mobile or trolley-mounted units if you require a pump for field or multi-location use.

Matching these factors with your operational needs ensures reliable performance and long-term durability.

Can oil transfer pumps handle high-viscosity fluids?

Yes, oil transfer pumps can handle high-viscosity fluids, but it depends on the pump’s design and power. For thicker oils—such as gear oils or cold-weather lubricants—you'll need a pump specifically engineered for high-viscosity transfer.

Key features to look for include:

  • High-torque motors or air-powered systems
  • Larger inlet/outlet diameters
  • Positive displacement technology (e.g., gear or rotary pumps)

Using a pump that’s not rated for high-viscosity oils may result in slow performance, overheating, or mechanical failure. Always check the manufacturer's viscosity rating before purchase or use.


How does an oil pump work in an engine?

An oil pump plays a crucial role in engine lubrication by circulating motor oil under pressure to the moving parts of the engine. Located typically near the bottom of the engine in the oil pan, the pump draws oil through a pickup tube and pushes it through the oil filter before distributing it to components like the crankshaft, camshaft, pistons, and valve train.

The oil pump ensures that all critical engine components are properly lubricated, reducing friction, cooling the engine, and preventing metal-to-metal contact. There are different types of oil pumps used in engines—such as gear pumps, rotor pumps, and vane pumps—but all serve the same essential purpose: to maintain oil pressure and circulation throughout the engine for optimal performance and longevity.

What are the signs of a failing oil pump?

Recognizing the symptoms of a failing oil pump early can prevent major engine damage. Here are common warning signs to watch for:

      • Low Oil Pressure Warning Light: If your dashboard warning light illuminates, it may indicate the oil pump isn’t maintaining adequate pressure.
      • Engine Overheating: Without proper oil flow, engine parts create excess friction and heat.
      • Tapping or Knocking Noises: Inadequate lubrication can cause components like the camshaft or lifters to produce unusual sounds.
      • Oil Pressure Gauge Reading Low: Consistently low readings may suggest a weak or malfunctioning oil pump.
      • Increased Engine Wear: Over time, lack of proper oil circulation can lead to accelerated engine wear and internal damage.
      • If you notice any of these signs, it’s crucial to have your engine checked by a qualified mechanic as soon as possible.

How often should an oil pump be replaced?

An oil pump typically lasts the lifetime of the engine, especially in well-maintained vehicles. However, replacement may be necessary if the pump fails or shows signs of wear—especially in high-mileage or performance engines.

There’s no set replacement interval like with oil or filters, but it’s wise to inspect or consider replacement:

      • Every 100,000 to 150,000 km if you notice symptoms of failure.
      • During major engine repairs (e.g., timing chain or oil pan removal), as preventative maintenance.
      • If you’ve experienced oil contamination, such as sludge buildup or metal shavings in the oil, which may damage the pump.
      • Using high-quality motor oil and changing it regularly is one of the best ways to extend the life of your oil pump and overall engine health.

What Is a Fluid Transfer Pump Used For?

A fluid transfer pump is a device used to move liquids from one location to another safely and efficiently. These pumps are widely used across industries such as agriculture, automotive, mining, construction, manufacturing, and marine.

Common Applications Include:

  • Transferring fuel, oils, chemicals, and water between tanks, drums, machinery, and vehicles
  • Refuelling equipment on-site
  • Draining and filling systems, such as cooling or hydraulic systems
  • Dispensing lubricants or chemicals in controlled volumes

Fluid transfer pumps are available in manual, electric, pneumatic, or engine-driven types, and are designed for specific fluids based on viscosity, chemical compatibility, and flow rate requirements.

How Do I Select the Right Fluid Transfer Pump?

Choosing the right pump involves evaluating several important factors:

  1. Type of Fluid

    • Identify whether you are transferring water, diesel, oil, chemicals, or corrosive liquids.

    • Ensure the pump materials are chemically compatible with the fluid.

  2. Viscosity

    • High-viscosity fluids (e.g., oils) require gear pumps, diaphragm pumps, or rotary pumps.

    • Low-viscosity fluids (e.g., water, diesel) can be handled by centrifugal or vane pumps.

  3. Flow Rate & Pressure

    • Determine how quickly you need to transfer the fluid, usually measured in litres per minute (LPM) or gallons per minute (GPM).

    • Choose a pump that meets both your flow and head pressure requirements.

  4. Power Source

    • Select between manual, 12V/24V, 240V, air-powered, or engine-driven pumps based on your site’s power availability.

  5. Portability & Mounting

    • For mobile applications, consider portable or trailer-mounted pumps.

    • For fixed installations, wall- or tank-mounted options may be more suitable.

      Working with a supplier experienced in industrial fluid handling can help ensure proper pump sizing and compatibility.

What Maintenance Is Required for Fluid Transfer Pumps?

Regular maintenance is essential to keep your pump performing efficiently and to extend its lifespan. Key maintenance tasks include:

  • Inspect Hoses and Fittings
    Check regularly for cracks, leaks, or worn connections.
  • Clean Filters and Strainers
    Blocked filters reduce flow and may damage components. Clean or replace as needed.
  • Lubricate Moving Parts
    For pumps with bearings or gears, apply appropriate lubrication at scheduled intervals.
  • Check Seals and Gaskets
    Replace any worn or damaged seals to prevent leaks.
  • Monitor Flow and Pressure
    Drops in performance may indicate internal wear or blockages.
  • Flush the Pump
    Especially important after handling corrosive fluids or when switching between fluids to avoid cross-contamination.
  • Follow Manufacturer Guidelines
    Each pump may have specific procedures outlined in the user manual.

Why Maintenance Matters
