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




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.





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.






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




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.
