Grundfos Max-E-Boost Single Pump Booster Set
Grundfos Max-E Boost Booster Set
The Grundfos Max-E Boost is a single pump, variable speed cold water booster set and is intended to supply boosted cold water from a water storage tank to a pressurised hot and cold water system at a constant outlet pressure. The Set comes complete with an integral pressure transducer, pressure vessel, non-return valve, isolating valves, pressure gauge, and anti-vibration mountings. A drain cock is included to simplify commissioning of the vessel precharge pressure.
It uses the latest variable speed E-pump motor technology to maintain a constant discharge pressure up to a maximum setting of 4.5 bar. The variable speed controlled operation of the Grundfos CRIE 5-5 pump helps to eliminate pipe work noise caused by water hammer which is generally associated with standard on/off controlled fixed speed water pumps.
Due to the Grundfos Max-E Boost Booster Set being quiet while running and small in size it is suitable for installation in a utility room or garage, or a frost protected outdoor enclosure.
The WRAS approved CRIE 5-5 stainless steel vertical multistage water pump is factory commissioned to deliver a constant 3 bar pressure at flow rates up to 2.3 l/s.
The pump motor control panel indicates operation and fault conditions, and allows simple adjustment of the discharge pressure from 0.5bar to a maximum of 4.5 bar.
The Grundfos Max-E Boost Booster Set has been designed and manufactured as a compact and cost effective solution for pressure boosting two or more standard bathrooms in large domestic properties.
The Max-E Boost Booster Set can be connected to any standard cold water storage tank approved by Water Byelaw having an AB Air Gap of adequate capacity to suit the water usage and consumption of the installation.
