12V Pumps

12 Volt Pumps for Diesel Petrol Oil and Water

Scintex is one of Australia's largest online suppliers of 12 volt direct current pump and pumping systems. Our specialty is in diesel transfer as well as heavier liquids like oils and motor oils. While most pumps are suited for room temperature fuels and oils we are proud to be a supplier of the Turbowerx range of high temperature oil transfer pumps and turbo scavenge pumps.  Electric 12V pumps can be used from your battery to pump diesel, oil, biodiesel, unleaded petrol and range of other fuels. High flow 12V pumps are available for quick transfer. For on board applications for your car, truck, 4x4 or machinery we have OEM Bosch pumps and Facet fuel pumps.  In many cases 12V pumps can be supplied in kit form, incorporating fuel hose, nozzles, flow meters and the fittings required for plumbing. Scintex can provide advice on how you can incorporate a 12V pump into your pumping application. We also supply a large range of stainless steel fuel fittings and fuel discharge & suction hose which can be supplied along with your pump. For water transfer Scintex can offer several options which are ideal for showers, drinking water transfer and small irrigation systems. Our quad water pumps have pressure cutoff switches and the small brass impeller pumps are ideal for marine applications such as bilge pumps. For onboard water and coolant pumps see our range of Bosch pumps.

Scintex is a pump and filtration specialist, with in-house engineers we can supply a pumping system suitable for you application. Our range varies from small 12V & 24V electric pumps to large 240V & 3 Phase pumps as well as hand drum pumps and pneumatic air pumps. Quickly and easily transfer fuels, diesel, oil, biodiesel, water and unleaded petrol. We also provide pumping solutions for the biofuel industry with biodiesel pumps and units for use in SVO conversions. Further to the automotive industry we supply intercooler and turbo oil scavenge pumps.

12V Pumps for Pumping Oils

Using a 12V Oil Pump for pumping oil is a common challenge due to the higher viscosity of the fluid. The viscosity of oil increases at lower temperatures and this often adds to the problem in cooler states around Australia. The table below shows the relationship of oil viscosity with temperature.

As oil viscosity increases, the amount of work or power it takes to move the fluid increases. An analogy to understand this is consider stirring honey in in a jar on a hot day verses taking a jar from a fridge and attempting to mix it, the cold honey will be very difficult to mix and will consume more of your energy (power) to stir. Pumping oil is very similar and this needs to be considered when selecting a pump. Incorrect pump selection can result in equipment damage and faulting.

Diesel oil pumps are often chosen by persons not understanding diesel oil is a very light and low viscosity oil. Diesel oil has a viscosity of between 2-6cP which is relatively low compared to common motor oil which would be 10cP plus. The table below provides some common fluid viscosities at a range of temperatures and tables such as the one below should always be consulted before simply selecting the most cost effective or simply available pump.

Where P is the pressure the pump will produce (Pascals(gauge))

ρ is the density of the fluid being pumped (kg/m3)
g is the gravitational force (m/s)
h is the height the fluid will be discharged (meters)
As a worked example, the scintex Quad pump http://www.scintex.com.au/collections/water-pumps/products/fresh-water-pump has a rated discharge pressure of 275kpag for the 17lpm model. To determine the discharge head this pump can produce we simply divide 275,000Pa by the fluid density (1,000kg/m3) and the gravity (9.8m/s) and this gives us a height of 28m. Therefore this pump can be used to pump water to the 4th story of a building without any problems.
