Grundfos CM Booster centrifugal pump

Sunday, 01 May, 2011 | Supplied by: Grundfos Pumps Pty Ltd


Grundfos has released a horizontal multistage centrifugal pump designed for light industrial applications. The CM Booster is controlled by the Grundfos Pressure Manager and features dry-run protection with auto restart and built-in thermal protection.

The CM pump’s 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. 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 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 integrates a pressure sensor from company’s 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 min) 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, reducing operating hours.
