6-year warranty. The latest innovation from Grundfos is the CMB-SP series of extremely efficient, self priming, fully automatic pressure pumps for household, commercial and 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 PM1 automatic controller provides instant control as well as protecting the pump against running dry. The PM1 also has a pressure indicator, power on light and several other indicators. The CMB-SP1-36 version supplies a flow rate of 22 litres per minute at 275 kPa which is more than enough for 2 showers to be used at the same time in a single level house. This is the pump & controller only version which has a standard 2-year warranty plus we give you an additional 2-years when you register your purchase with us and a further 2 years when you buy and install a 60 litre tank on the system. 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. Free Delivery in Australia. Click here for the spec sheets. Operating curve.
