Fuel Transfer Pump with Flow Meter Sets: Heavy-Duty Fueling Kits for Equipment Operations
Quick Answer: A fuel transfer pump with flow meter set combines a 12V or 24V DC pump, an oval gear flow meter, a hose, a nozzle, and a filter. This kit measures diesel, biodiesel, or light oil delivery for generators, excavators, mining trucks, and agricultural machines. Silver Automation Instruments supplies heavy duty fueling kits with flow meter accuracy of ±0.5 percent and flow ranges from 20 to 120 litres per minute.
What Is Included in a Heavy Duty Fueling Kit
A typical kit from Silver Automation Instruments includes a 12V DC or 24V DC gear pump, an oval gear flow meter, a manual or automatic nozzle, a 4 metre oil resistant hose, a 100 micron filter, and DN25 or DN40 fittings. The pump body is cast iron or die cast aluminium. The flow meter can be aluminium or stainless steel depending on fuel type and site conditions.
Equipment fleets in Southeast Asia, Australia, Africa, and Latin America often refuel in the field. A standard pump without a meter cannot track how much fuel goes into each machine. That creates inventory loss and bad cost control. A fuel transfer pump with flow meter set solves this. It delivers fuel and records volume at the same time.
Flow Meter Selection for Diesel and Light Fuel
For diesel transfer we recommend an oval gear flow meter. It handles viscosity from 2 to 100 cP and gives stable readings even when fuel temperature changes. Accuracy is ±0.5 percent of reading with repeatability of ±0.2 percent. Standard flow meter sizes are DN15 and DN25. Flow ranges cover 10 to 60 litres per minute for DN15 and 20 to 120 litres per minute for DN25. The meter output can be local totalizer or 4-20 mA with optional pulse output. For billing or fuel management software, choose pulse or 4-20 mA. For simple field refueling, a mechanical register is enough.
Here is the thing about cheap pump sets. They come with plastic meters that fail after a few months. We have seen this on customer sites in Indonesia and Nigeria. The meter gears swell when biodiesel or high sulphur diesel passes through. Then the display freezes or leaks. A heavy duty oval gear meter with metallic gears avoids this. That is why we specify metallic gears in all fuel transfer pump with flow meter sets.
For diesel transfer at 40 to 80 litres per minute, we recommend the Silver Automation Instruments OGM-DN25 oval gear flow meter with a 24V DC gear pump.
Pump Power and Flow Rate
Mobile service trucks use 12V or 24V DC gear pumps. Fixed fuel depots use 220V or 380V AC pumps. The pump flow rate should match the flow meter range. If the pump delivers 100 litres per minute but the meter is sized for 60 litres per minute, the meter will wear quickly and readings may drift. In practice, most equipment operations need 30 to 80 litres per minute. That covers excavators, wheel loaders, generator sets, and farm tractors.
Common Applications We Have Supplied
A mining contractor in Western Australia ordered 12 heavy duty fuel transfer kits for a Caterpillar fleet. Each kit used a 24V DC pump, a DN25 aluminium oval gear flow meter, and a 6 metre hose. Fuel consumption data went into a maintenance sheet for each truck. Another customer in Vietnam bought 8 kits for diesel refueling at a coffee plantation. The site used generator sets and small trucks. Th

Last year a customer in Brazil asked us for a fuel transfer pump with flow meter set for ethanol blended petrol. That fuel attacks standard rubber seals. We supplied Viton seals and a stainless steel oval gear flow meter. The kit has worked for 10 months without leaks.
How to Order the Right Fuel Transfer Pump with Flow Meter
Send us your fuel type, flow range in litres per minute, pressure in bar, pipe size in DN, and power supply. For diesel at 50 litres per minute and 2 bar, we usually propose a 24V DC pump, a DN15 oval gear flow meter, and a 100 micron filter. For biodiesel, tell us the blend ratio. Higher biodiesel content can swell standard seals. We then select Viton seals for the flow meter and pump. For high accuracy billing, ask for a pulse output meter. For simple inventory control, a mechanical register is cheaper and easier to read.
Installation and Maintenance Tips
Mount the pump and flow meter on a skid or tank frame. Keep the flow meter downstream of the filter to protect the gears from dirt. Use a 100 micron filter before the meter and a coarse strainer before the pump. After each shift, run clean diesel through the meter for 15 seconds to reduce residue. For monthly checks, remove the meter cover and inspect the gears. If you see scratch marks or metal particles, clean the filter and check the pump strainer. Calibrate the flow meter every 12 months if you use the data for billing or fuel reconciliation.
Frequently Asked Questions
Which flow meter type works best for diesel fuel transfer? An oval gear flow meter with aluminium or cast iron body works best for diesel. It is accurate at low and medium viscosity, and it does not require straight pipe runs. A turbine meter can also work but may be less stable when flow starts and stops frequently.
Can the kit measure fuel for each machine separately? Yes. Install the flow meter downstream of the pump and record the register after each refueling event. For automatic tracking, use a pulse or 4-20 mA output and connect it to a fuel management terminal.
What is the difference between 12V and 24V DC pumps? 12V DC pumps fit small service trucks and pickup tanks. 24V DC pumps fit heavy trucks, mining vehicles, and generator service trailers. Both can deliver 30 to 80 litres per minute. Choose based on the battery system on site.
How long does delivery take? Standard fuel transfer pump with flow meter kits ship within 7 to 10 working days after order confirmation. Custom flow ranges or stainless steel flow meters may add 5 to 7 days. We ship to Australia, Southeast Asia, the Middle East, Africa, and Latin America by air or sea freight.
