Grundfos (Danish): circulatory pumps, pressure pump and energy-saving technology

Grundfos is one of the world’s largest pump manufacturers, especially strong in circular pumps for heating, air conditioning and water supply.The company is well known for its tendency to integrate frequency inverters and smart controls into the pump itself.

The origin

Grundfos was founded in 1945 in Bjerringbro, Denmark, by Poul Due Jensen. The company is owned by the Poul Due Jensen Foundation, a model that helps to focus on long-term growth.

The product groups.

• The full pump:Heating, air conditioning and hot water.
• High pressure pump, multi-layer pumpBuilding water supply, industrial.
• Water pumping and water pumping:drainage and treatment of waste water.
• Quantitative pump and water solution:treatment of water and chemicals.

Energy saving lessons.

According to the same rule, the pump capacity is proportional to the speed equalization: a 20% reduction in speed can reduce almost half the power. The integrated inverter pump adjusts the speed according to the actual voltage or flow, avoiding flow by valve. This is why the speed control pump is increasingly popular in HVAC and water supply.

Kenflo centrifugal pump for HVAC and water supply

Central air conditioning and building water supply can be used.The Kenflo pump.: KTP air conditioning pump, GD in-line pump, KGP mounted straight on the pipeline, KMP monoblock pump, KDL multi-layer standing pump and FBJK-W water supply unit. Combined with frequency inverter, these configurations allow adjustment of flow according to load.Contact us .to be selected according to the pressure column.

Frequently asked questions.

Is the circulatory pump other than the usual centrifugal pump?

The principle is the same, but circulatory pumps are for closed systems, low-voltage columns, usually in-line, optimized for smooth operation and performance in variable flow ranges.

Should I use the inverter for every pump?

No. Frequency inverter is effective when the need varies; with the pump always running close to the design point, the benefit is small.
