Grundfos-Pressure Manager (PM1, PM2) Domestic water supply and booster systems

 

 

Overview

grundfos-PM1&2The all-in-one Grundfos Pressure Manager is an intelligent waterworks that controls your pump in accordance with consumption in domestic water supply and booster systems.

The Pressure Manager covers all needs in both simple and complex applications.

This Grundfos-developed, state-of-the-art product offers our well-known quality and our special touch with respect to innovative features and functionality, system integration, plug-and-pump convenience, and ease of use.

Pressure Manager offers a choice of two excellent models: the PM1 for basic flexibility, and the PM2 for all-round control.

 

 

Applications

PM 1 – BASIC FLEXIBILITY

CM_Booster_PM1The PM1 is suitable for applications where start/stop of the pump according to consumption is required. It is the basic flexibility solution, offering pump start at 1.5 or 2.2 bar.

The PM1 starts the pump when the starting pressure is reached, and keeps running as long as there is flow.

The PM1 provides dry-running protection and a cycling alarm for increased safety. In addition, it boasts the usual Grundfos quality, which guarantees high flexibility, robust electronics, and long life.

 

 

 

 

PM 2 – ALL-ROUND CONTROL

Grundfos-CM-PM2The PM2 is the all-round control solution, offering adjustable pump start at 1.5 to 5 bar. This enables customisation to different types of installation and desired comfort levels. The start pressure is set inside the unit, whereas current pressure is read on the intuitive LED display on the front of the Pressure Manager.

The PM2 starts the pump when the starting pressure is reached, and keeps running as long as there is flow.

The PM2 is equipped with an internal pressure tank to minimise starts and stops in the event of leakage in the installation.

In addition, the PM2 can be optimised for operation with a large external pressure tank by enabling the 1-bar differential pressure function. This significantly reduces the number of operating hours of the pump in installations with a pressure tank.

Grundfos-DMX Dosing, Diaphragm pump

 

 

Overview

DMX Diaphragm DosingGeneral

The Grundfos DMX range has proven its worth in dosing applications worldwide. With their robust diaphragm-based design and their high-quality motors DMX pumps require minimum maintenance and are best choice for many dosing applications. The DMX range is highly versatile: it covers a wide flow range and offers a variety of dosing head sizes, materials and accessories.

 

Accurate dosing – all the time

The diaphragm design ensures that the dosing flow variation is below ± 1.5 % and the linearity deviation is kept below 4 % at all times. This allows very precise dosing of your chemicals – as much as necessary, as little as possible.

 

Smooth and low-pulsation dosing

The DMX series combines sophisticated drive technolo­gy and gear kinematics to ensure smooth and low-pulsation dosing without pressure peaks. This means less stress to all system components, such as tubes and valves, and leads to longer service intervals for the entire system.

 

Motors to match application needs

WcapsImage-1For applications with specific motor requirements, the versatile DMX range offers high-quality motors for 50 Hz, 60 Hz, 100 Hz (with Variable Frequency Drive VFD), as well as EX classified or ATEX-certified motors, if required.

 

Perfect material selection – for housing and liquid-wetted parts

The smaller DMX models have plastic housings offering chemical resistance and all the protec­tion necessary for many applications. The larger models have a robust cast-aluminium housing with epoxy coating to meet all application needs. Investment costs and running costs for spare parts are kept low over the years: A wide choice of materials for dosing head, valves and accessories allow selecting exactly the degree of chemical resistance required. All liquid-wetted parts need to be resistant to the chemicals used. The diaphragm is made of NBR and PTFE-coated.

 

Compact design – saves money and space

DMX pumps are available in 12 different dosing head sizes. Careful design work has kept them all very compact. This saves material costs and allows placing several pumps right next to each other in confined spaces. Double-head versions (DMX models 226 and 227) offer a very cost-efficient way to save space or to dose two different chemicals. The extra capacity offered by double-head versions can also be used to gain higher flow rates for a single chemical.

 

Screenshot_2Accessories ensure perfect operation of the entire system

A wide range of accessories specially designed for the DMX series help optimise performance: AR control electronics (contact signal control with multiplier and divisor function, 4-20 mA control or stroke frequency control via display and key pad, low-level/empty signal), integrated relief valve, dosing controller, diaphragm leakage detection, servomotor for automatic stroke length adjustment, PTC motors with Variable Frequency Drive (VFD). We also offer system components such as pressure loading valves and pulsation dampers.

Applications

Disinfection, coagulation, flocculation, precipitation, etc. in:

  • Drinking water treatment
  • Waste water treatment
  • Pulp and paper industry
  • Textile industry
  • Cleaning water treatment
  • Food & Beverage industry, dairies

Grundfos-Hydro-Multi-S-CR_finalInstallation

Commissioning

This product can be installed as part of a large-scale solution in which a number of Grundfos products operate together. In order to achieve optimum performance, it is very important that the system is set up and adjusted correctly from the outset. The knowledge and experience of the Grundfos service technician, and the use of dedicated Grundfos service tools to adjust the performance of the pump, together guarantee that the greatest possible efficiency and fully correct operation of the equipment are both achieved. Commissioning is recommended in the following circumstances:

  • If two or more Grundfos products operate together in a system, e.g. in booster or wastewater systems
  • If the pumps are installed in a large system, e.g. in a building management system
  • If the user wants to be trained in the proper operation of the pumps/system
  • Where the setup is crucial for the Grundfos product to operate for its full planned life, e.g. in water treatment applications. In such cases commissioning is not only recommended but required
  • Where safety is an issue, e.g. in disinfection systems.

Recommended spare parts

Even though the Grundfos strategy is to supply the best possible pump solutions to our customers, after a long period of operation there will be wear and tear to some of the components in certain situations. If short operating downtime is a requirement, or if the pump is installed in inaccessible areas where delivery of spare parts may take a long time, it is advisable to maintain a small stock of recommended spare parts on site.

Grundfos-S Pump

 

 

Grundfos-S-horizontalOverview

S pumps form the backbone of many sewage systems. They are selected for their strength, their durability, and for innovative features such as the SmartTrim impeller clearance adjustment system and the Smart Seal for leakage prevention.

The SmartTrim system used on the S-pumps makes it easy to adjust the factory-set impeller clearance and thus to maintain maximum pump efficiency.

The Grundfos SmartSeal Auto-coupling gasket provides a completely leak-proof connection between the pump and the base unit of the auto-coupling system. The shaft seal is capable of rotating in either direction. When the pumps are installed with separate pipework, sludge sedimentation can be avoided by back-flushing the system at regular intervals.

Applications

Grundfos-Srange VThe pumps are suitable for the following applications:

  • Transfer of unscreened raw sewage
  • Transfer of raw water
  • Pumping of water containing sludge
  • Pumping of industrial effluent.

  • SmartTrim
  • Operation with/without cooling jacket
  • Submerged or dry installation
  • Channel and vortex impellers
  • Built-in motor protection
  • SmartSeal
