What type of pumps are used to overcome boiler pressure?

Positive displacement pumps are specifically designed to handle fluid movement by trapping a fixed amount of fluid and forcing it into the discharge pipe. This mechanism enables them to create high pressures, which is essential in applications like overcoming the pressure found in boilers. In the context of a refrigeration or heating system, overcoming boiler pressure often requires a reliable and consistent flow of water or steam, which positive displacement pumps can effectively provide.

These pumps are particularly useful in systems where the flow rate is constant and needs to be maintained regardless of the pressure conditions. By delivering a precise volume of fluid on each cycle, they ensure that enough pressure is generated to circulate the water or steam throughout the system, ultimately maintaining the required temperatures and pressures in the boiler.

Other types of pumps, while they may be suitable for various applications, do not generally provide the same level of efficacy in overcoming high pressure as positive displacement pumps do. For example, rotary pumps can be effective in moving fluids but may not generate the same consistent high pressures necessary for boiler systems. Submersible pumps are typically used for pumping fluid from below ground level, while diaphragm pumps are useful in specific applications but may not deliver the same pressure capabilities required for this task. Thus, positive displacement pumps are the most effective choice for overcoming boiler
