If you install a more powerful pump in a boiler system, it can increase the flow rate of water or steam, potentially improving heating efficiency. However, this can also lead to excessive pressure, which may risk damaging pipes, valves, or other components. Additionally, a pump that is too powerful might disrupt the system's designed hydronic balance, causing uneven heating or increased wear on equipment. Proper sizing and compatibility with the system's design are crucial to avoid these issues.

If the boiler is up to temperature, then the problem is with the pump. If the boiler is cold you should call a pro, as there is no way to diagnose it from here with out more info.
TDBFP = Turbine Driven Boiler Feed Pump
Yes, a circulating pump on a hot water boiler can be installed on either the inlet or outlet side. However, it is more commonly placed on the outlet side to ensure that the pump is moving hot water away from the boiler and into the heating system. This configuration helps maintain a consistent temperature and reduces the risk of cavitation. Ultimately, the specific installation may depend on the system design and manufacturer recommendations.
3 things 1) the plumber sends you a bill 2) the new pump is expected to move more water through the loop than the old pump, usually at a significantly higher unit cost but only slightly higher electrical consumption 3) ideally result 2 will move more water around the radiant loop resulting in a less temperature drop around the loop, more even heat radiation for better comfort and a higher return water temperature into the boiler potentially improving combustion efficiency and boiler lifespan, but "your mileage may vary"
The boiler feed pump pumps hot feedwater into the boiler. The boiler pressure is to high for water to flow into it by gravity, so a pump is required.

A digester feed pump forces water to a boiler. It works by transferring cool water to the boiler to be heated.

Boiler feed pumps are an important part of any boiler operation. They control the amount of water fed to the boiler and the manner in which it is fed.

If the washer in a boiler pump has gone, it does not necessarily mean you need a new pump. In many cases, you can replace just the washer or seal, which can resolve the issue. However, if the pump shows signs of wear, leaks, or other damage, it may be more cost-effective to replace the entire pump. It's best to assess the condition of the pump and consult a professional if unsure.
Boiler feed pump's suction pressure be aprox. 15Kg/cm2 and discharge pressure be 180Kg/cm2. So the balancing line balance the pressure and protect the boiler feed pump. my quastion is that what is the working principal of balancing leak off
