The key difference between a suction pump and a pressure pump lies in their function: a pressure pump pushes fluid into a system, while a suction pump draws fluid in.
Let's break down the functionalities:
- Pressure Pump: Pumps fluid from a source (like an internal bath tank) into an external system. Think of it as a "pushing" action.
- Suction Pump: Draws fluid from the system through a return line. This acts like a "pulling" or "sucking" action.
The technical specifications will often list two separate capacity values, one for pressure and one for suction, reflecting these different functions. As the reference states: "While the pressure pump pumps the fluid from the internal bath tank into the external system, the second pump sucks the fluid through a return line into the bath...there are two separate values for the pressure and suction capacities stated in the technical specifications."
| Feature | Suction Pump | Pressure Pump |
|---|---|---|
| Function | Draws fluid into a system or reservoir | Pushes fluid into an external system |
| Action | "Pulling" or "Sucking" | "Pushing" |
| Location (Example) | Return Line, drawing fluid back to bath | Internal Bath Tank, pushing fluid outwards |
| Capacity | Suction Capacity | Pressure Capacity |
