Pump type and how to maintain
Main pump type
A variety of fuel transfer pump designs exist to accommodate different liquid characteristics and pipeline setups. The main types include:
– Centrifugal: These widely used pumps use the centrifugal force of the impeller to throw the liquid outward. The flow rate depends on the diameter and speed of the impeller.
– Positive displacement: Rotating gears, blades or cams capture and extrude a fixed volume of liquid with each rotation, and the flow rate is very stable;
– Diaphragm type: Flexible diaphragm through the reciprocating movement of the connecting rod to discharge the liquid, suitable for the treatment of abrasive and solid containing liquids;
– Peristaltic: roller compresses flexible pipe, pushes liquid through in wave motion, has self-priming function, suitable for liquid with high solid content;
– Submersible: This is a sealed pump and motor design designed to be immersed in the liquid being transported, usually installed in a well or tank without additional primer.
Transfer pump maintenance skills
In order to maintain the performance of the pump, regular inspections and maintenance are required according to the running time. Key maintenance tips include:
1. Check whether the pump shell, seals and joints are leaking;
2. Check whether the pressure gauge reading is accurate;
3. If you are worried about icing, please drain the liquid;
4. Check and replace worn impeller blades;
5. Clean the debris in the impeller, shell and filter;
6. Confirm whether the motor is running normally and ensure good lubrication;
7. Test safety devices such as pressure relief valves.
For optimal service life, make sure to use within the design capacity of the pump and avoid size that is too large or too small. Avoid stress on components due to idling and fast cycling. Keep solid loads within limits and properly store pumps between uses. Whether you need to empty a waste pit, refill a water tower or top up a chemical mix tank, fuel transfer pumps ensure the process runs smoothly.
