The latest innovation from Grundfos is the CMB series of extremely efficient fully automatic pressure pumps for household and light industrial water pressure supply. Horizontal multistage pumps that are extremely quiet, all metal parts that come in contact with water are made from stainless steel. The PM2 automatic controller provides instant control as well as protecting the pump against running dry. The PM2 also has a pressure indicator, power on light and several other indicators. The CMB5-6 version supplies a flow rate of 82 litres per minute at 450 kPa which is more than enough for the largest home with 2 or 3 levels and up to 4 showers at one time. This unit can also be used for irrigation, washdown or many other applications where a high flow at a higher pressure is required. This is the pump & controller only version which has a 2-year warranty. One of the warranty terms is that the pump needs to be installed in a building or under a pump cover and off the ground.
