GRUNDFOS PRESSURE MANAGER

The Grundfos Pressure Manager 1 is suitable for applications where the start/stop of the pump is needed according to the consumption. The solution offers the booster to start at 1.5 or 2.2 bars. PM1 starts the pump when reaching the starting pressure and keeps running as long as there is a flow. PM1 offers dry-running protection and a cycling alarm for increased safety in addition to the usual Grundfos quality, which guarantees high flexibility, robust electronics, and
long life.

PM 2 – ALL-ROUND CONTROL

The Grundfos PM2 is an all-around control solution offering a pressure setting range between 1.5 and 5 bar. The starting pressure is set inside the unit, whereas the current pressure is read on the intuitive LED display on the front of the Pressure Manager.PM2 starts the pump when reaching the starting pressure and keeps running as long as there is a flow. PM2 is equipped with an internal pressure tank to minimize starts and stops in case of leakage in the installation. In addition, PM2 can be optimized for operation with a large external
pressure tank by enabling the 1 bar differential pressure functionality. This significantly reduces the number of start/stops of the pump.

Features

User-friendly interface
PM Range has a user-friendly interface with LED indicators showing:
• Power on
• Pumps running
• Alarm indication
Flexible power supply
Due to robust electronic components, PM Range can be powered by a generator or other alternative power supplies
Protective functions
PM TWIN incorporates several functions that protect both the pumps and the installation:
• Dry-running protection
• Cycling alarm
• Maximum continuous operating time (30 min) except PM1
• Auto-reset function which can be used to automatically restart the system in case of dry running, except PM1

Internal pressure tank
PM TWIN is equipped with a small internal pressure tank, which minimizes the number of starts and stops of the pump in case of minor leakages

PM TWIN

The all-in-one Grundfos PM TWIN is an intelligent controller, that controls two pump solutions with duty/standby mode, by consumption in domestic water supply in the range of 1.5 - 5 bar. PM TWIN is designed for automatic start/stop control of Grundfos pumps and other water supply pumps in a home environment. PM TWIN can be adapted to the individual installation through a number of DIP switches located behind the operating panel.

Applications

Typical applications are water supply
systems and rainwater systems in:
• One-family houses
• Blocks of flats
• Villas and cottages
• Horticulture and
