Grundfos CM & CME BOOSTER PUMPS

New from Grundfos introducing the exciting CM Booster range

The CM Booster is a horizontal multistage centrifugal pump designed for domestic and light industrial applications. It is suitable for pressure boosting from above ground rainwater tanks and from mains water

The pump, called the Grundfos CM Booster, which is controlled by the new Grundfos Pressure Manager, features dry run protection with auto-restart and built in thermal protection.

The CM pumps wet components are all constructed from 304 Stainless Steel, and both the pump and Pressure Manager have been certified to comply to the Australian and New Zealand standard for products in contact with drinking water - ATS/NZ 5200.030 and AS/NZS 4020 .

 Like its predecessor, the Grundfos CH, the CM is one of the quietest pumps on the market.

 The Grundfos Pressure Manager (PM) is a compact control unit especially designed for domestic water supply pumps.

 The PM sets new standards for integration of functionality and intelligence in domestic pump controls.

 There are two versions of the Pressure Manager – PM1 and PM2. Both the PM1 and PM2 feature some great protective functions including dry-running protection and cycling alarm.

 They have also both been specifically designed for use with generators.

 For installations in confined spaces, or where there is extensive pipe work, the PM1 and PM2 can be freely positioned as the flow switch uses a spring as a return mechanism instead of gravity – meaning that orientation is not a problem.

 The Grundfos PM1 adds an extra degree of control to domestic pressure boosting when used in    conjunction with a CM pump. The PM is equipped with an integrated flow switch to optimise operations and ensure maximum protection for the pump.

 In addition, the flow switch serves as a non-return value, resulting in a considerable reduction in pressure loss compared to traditional non-return value and flow switch solutions.

 The PM2 offers an entirely new and improved opportunity for pressure measurement as it integrates a pressure sensor from Grundfos Direct Sensors ™. The sensor supplies continuous information of the pressure in the system, enabling installers and end-users to read current pressure on a LED display, adjust the starting pressure (between 1.5 and 5 bar) and start and stop the pump according to pressure.

 The PM2 also features options of a maximum continuous operating time (30 minutes) and an auto reset function.

 Another key feature of the CM Booster with PM2 is that it can be optimised for operation with large external pressure tanks by enabling the 1 bar differential pressure functionality, significantly reducing operating hours.
