1.      Include hot water supply in each zone – Grundfos Pressure Boosting

If the pressure boosting system is divided into zones, we always recommend that you include a hot-water production unit in each zone. Thay way, you avoid large differences in pressure betwen the hot and cold water.

2.      Always use dry-running protection ! – Grundfos Pressure Boosting

We always recommend that you add dry-running protection to your pressure boosting system. Exactly how you do this depends on the type of system. If your booster system is connected directly to the water supply, you should use a pressure sensor to monitor that there is sufficient pressure to the pump. If your system uses a break tank, use a level sensor in the tank instead.

 3.      Where should I place non-return valves ? ­- Grundfos Pressure Boosting

In systems exposed to inlet pressure-i.e. systems that are connected directly to the water supply – we recommend that you place the non-return valves after the pumps. This prevent the pressure inside the pump from becoming too low, so you avoid problems with air being sucked through the shaft seal.

If your system is subjected to suction pressure – i.e. if it is connected to a break tank – you should place the non-return valves before the pumps.

Grundfos NK/NKG pumps are used in water supply, industrial pressure boosting, industrial liquid transfer, HVAC (heating, ventilation and air-conditioning), irrigation and process industries.

Grundfos end-suction pumps are multi-purpose pumps suitable for a variety of different applications requiring reliable and cost-efficient supply. End-suction pumps are used in five main areas of application: water supply, industrial pressure boosting, industrial liquid transfer, HVAC (heating, ventilation and air-conditioning), and irrigation.

The pumps are all non-self-priming, single-stage, centrifugal volute pumps with axial suction port, radial discharge port and horizontal shaft. The Grundfos NK/NKG range comprises a complete series of long-coupled pumps that comply fully with either EN733 or ISO2858. The pumps are of the back pull-out design, enabling removal of the motor, coupling, bearing bracket and impeller without disturbing the pump housing or pipework. Even the largest pumps can thus be serviced by one person with a crane. The ISO2858 range of pumps are available with a bearing life of 100,000 hours, and Grundfos NK/NKG Pumps  can be fitted with double seals. They available in a stainless steel version as an option.

Applications of  Grundfos Nk/NKG End Suction Pumps

Grundfos offers a virtually limitless range of long-coupled (NK) end-suction pumps. Their sturdiness and reliability make them ideal for use in demanding environments such as the following:

• District heating plants
• Heating systems for blocks of flats
• Air-conditioning systems
• Cooling systems
• Wash down systems
• Other industrial systems.

Features and benefits of Grundfos NK/NKG Pumps

• Optimised hydraulics in housing and impeller = unimpeded liquid flow
• O-ring seal between pump housing and cover = no risk of leakage
• Housing, impeller and wear ring in different materials = improved corrosion resistance, no sticking elements
• Back pull-out design for easy dismantling for service
• Pump is electro-coated to increase corrosion resistance
• Available with IE1, IE2 and IE3  motors
• PN 10/16 and 25 bar
• Temperatures up to 180 °C
• Available in a number of shaft seal and material variants.

Grundfos offers a wide range of dosing pumps representing state-of-the-art technology.

Grundfos Digital Dosing solutions (SMART Digital, DME, DDI) set new standards in liquid chemical handling and accuracy. The operator can easily install and set up the pump to discharge exactly the quantity of dosing liquid required for the process in a unique drive- and flow-control management concept. The setting of the pump is displayed in ml/h, l/h or gph, and the operation mode is easily identified by means of icons.
