water pump
隔膜泵 蠕动泵 潜水泵
| Pump Type | Pressure Ability | Flow Rate | Advantages | Disadvantages | Suitability for Water Gun |
|---|---|---|---|---|---|
| Diaphragm Pump | High (can make strong jet) | Medium | Self-priming, good pressure, portable | Noisy, limited flow | ✅ Best choice for high-pressure water gun |
| Peristaltic Pump | Very Low | Very Low | Clean fluid path, precise dosing | Very weak flow and pressure | ❌ Not suitable |
| Submersible Pump | Low (mostly free flow) | High | Large continuous flow, simple design | Cannot build strong jet, only steady flow | ⚠️ Suitable only for fountain-like spraying |
| Jet Pump | Medium to High | Medium | Can lift and pressurize water, durable | Less efficient, higher power demand | ✅ Possible, but more complex than diaphragm |
- A self-priming pump is a type of centrifugal/impeller pump designed to lift water automatically.
- A diaphragm pump uses a flexible membrane, usually for higher pressure but lower flow, and can handle more challenging fluids.
Jet pumps
Jet pumps usually do not belong to diaphragm pumps, peristaltic pumps, or submersible pumps.
Their classification is:
A jet pump (also called an ejector pump) belongs to the jet pump category, which relies on a high-speed jet of fluid to create negative pressure for suction and liquid delivery.
Unlike diaphragm pumps and peristaltic pumps, it has no elastic diaphragm or tube-squeezing mechanical structure.
Unlike submersible pumps, it does not rely on an impeller for direct pressurization, but instead uses the nozzle jet principle.
