Hot water boilers
Grundfos’ single-stage and multistage pumps for hot water boilers are available for temperatures up to 140°C. All pumps can be supplied with motors with a wall-mounted or integrated frequency converter (up to 22 kW), ensuring that the pressure and temperature in the system are constant. If the boiler requires a shunt in order to avoid thermal stress, we offer highly reliable pump solutions that will hold the temperature in the boiler constant.
|The very high temperature of hot liquids can be damaging to the pump and even destroy the shaft seal.||Grundfos offers specially designed shaft seals that handle water temperatures up to 180°C.|
|The application's inlet conditions are poor.||An advanced Grundfos low NPSH pump is available, efficiently reducing NPSH and eliminating cavitation.|
|When temperature control is part of the process, the pump material is potentially stressed because of the continuous thermal expansion and contraction.||By applying one of Grundfos' speed-controlled pumps the temperature is held constant.|
|Mechanical regulation valves are very expensive.||Grundfos' E-solutions completely eliminate the need for this particular valve as the water inlet is automatically adjusted to the fluctuating steam demand on the outlet.|
|Erratic load characteristics are a frequent problem.||Grundfos offers tailor-made software to stretch the pump curves, allowing pumps to operate outside their set curves and increase efficiency.|
|Energy consumption is important to your customer.||Grundfos' high-efficient E-solutions significantly reduce energy consumption by automatically adjusting pump performance to the actual need. Naturally, the E-solutions meet international efficiency standards.|
|Stock management can be difficult due to the global differences in voltages and frequencies.||Grundfos' E-solutions feature dual frequency and a wide voltage range, allowing you to use the same solution all over the world. Naturally, the E-solutions carry the necessary approvals.|
- As boiler shunt applications are often subjected to very high ambient and liquid temperatures it is essential to carefully design the pump for this demanding environment.
