Grundfos Multistage Centrifugal Pumps

The Grundfos CR vertical, multistage, centrifugal in-line pump family works for water supply, water treatment and almost any industrial solution – including those for high-pressure, hot, dangerous, flammable and aggressive liquids.

Now, the range has been upgraded with a new, more robust generation of CR pumps (CR 95, CR 125 and CR 155), offering an optimised hydraulic design for world-class energy efficiency.

Thanks to a small footprint, the pumps are also easier and less costly to install than comparable pumps.

The new CR pumps have been developed using simulation-driven design to perfect every single component and have been field-tested around the world, so you can install and operate the range with total confidence.

Grundfos Hydro 2000 Pressure Booster Systems

The Grundfos Hydro MPC booster systems are made to the very highest standards. Thanks to the CU 352 controller, they handle even the most difficult boosting jobs with ease and accuracy.
All components have been combined with focus on quality and efficiency. The Grundfos Hydro MPC booster systems are designed to last: sturdy, compact units with easy access to all service parts. Grundfos Hydro MPC booster systems can be used wherever additional pressure is required. Each booster model has been designed to meet specific customer demands for capacity and control.

The intelligent cascade control ensures that the optimum number of pumps required to meet the demand runs at any time. Together with the CR with IE3 motors, this makes the Hydro MPC the most energy-efficient solution for maintaining a constant pressure during changing flow demands.

Grundfos Stainless Steel Submersible Pumps

The Unilift AP and Unilift AP Basic are submersible drainage pumps designed for both temporary/portable installation and permanent free-standing installation. These single-stage pumps are made mostly of stainless steel. All types are available in either single phase or three phase versions and for 50 or 60 Hz power supply.

The number in the type designation, e.g. AP12, indicates the spherical particle size that can pass through the pump.

All Unilift AP and AP Basic pumps are fitted with a plug for connection to the mains.

Unilift AP is a single stage pump with either semi-open impeller (AP12) or with vortex impeller (AP35 and AP50). All Unilift AP pumps are fitted with a stainless steel sleeve for cooling during operation. The strainer at the bottom prevents particles larger than the pump is designed for from entering the pump. The strainer is clipped onto the pump housing. All Unilift AP pumps can be supplied with or without float switch, for automatic or manual operation. Pumps with an ”A” in the type designation are fitted with a float switch. 3-phase versions have an additional starter box connected to the float switch. The outlet is positioned at the top of the pump and is available in Rp 1 1/2 to Rp 2.

An optional non-return flap valve can be fitted in the outlet in order to prevent backflow.

Unilift AP Basic pumps are single-stage pumps (AP35B, AP50B) with vortex impeller. All Unilift AP Basic pumps are made of stainless steel, with a composite baseplate. The Unilift AP Basic range is designed for submerged operation, either free-standing on the base plate or installed using an auto coupling. The pump inlet is designed to prevent to large particles from entering the pump. The base plate is clipped on by means of four clips hidden under the composite ring at top of the pump housing. The ring prevents dirt from sticking to the clips. All Unilift AP Basic pumps can be supplied with or without float switch, for automatic or manual operation. Pumps with an ”A” in the type designation are fitted with a float switch. The outlet is positioned at the side of the pump and is R 2.

Grundfos Pressure Systems

A pressure boosting system is designed to increase low pressure in a water system in order to achieve sufficient water flow and pressure to consumers.

Pressure boosting systems generally consist of one or more pumps which are installed in a booster system to increase the pressure in a system to a certain point independent of flow and inlet pressure.
 
System configuration
Pressure boosting systems are available in various system configurations, each offering different advantages and characteristics such as comfort level, initial investment cost, running costs, flexibility and supply assurance.
 
Examples of pressure boosting configurations:

  • Direct boosting systems: A system where a booster set connected directly to the water mains serves the whole building or only the upper parts of it.
  • Zone divided systems. Here, a number of boosters connected to the water mains or a common break tank serve their own pressure zone.  
  • Roof top tank systems. Here, a booster fills up a roof tank from where the water uses gravity to run to the consumer. This system often has a separate booster set serving the upper floors where the pressure is too low due to insufficient geometric height.
  • Series connected system with intermediate break tanks. Here, every booster serves its own pressure zone in a building, drawing from its own break tank which is located on a separate floor. 
  • Series connected system without intermediate break tanks. Here, the boosters are connected directly in series.  

 
 
Variable Frequency Drive (VFD) controlled systems
VFD controlled systems can deliver the exact needed amount of water thus ensuring that only the needed energy is consumed. These systems also have the advantage that the set point can be altered according to the flow, ensuring that the energy loss due to resistance in pipes is reduced. So even though the initial investment in such a system is higher than in a non-VFD system, the low running cost, the high comfort level and the flexibility of the system often justify the investment.
