Description

The MSR Guardian Purifier Pump is a pump purifier designed to treat freshwater in demanding environments. It is suited to long expeditions, travel, self-sufficient missions and emergency situations where water quality is uncertain.

Its hollow-fibre membrane eliminates protozoa, bacteria and viruses from water. It can therefore be used in areas where a basic microfilter is not sufficient, particularly where the risk of viral contamination is higher.

Operation is straightforward: place the intake hose in the water source, then use the pump to transfer purified water directly into a bottle or other container. Flow rate can reach 2.5 litres per minute, allowing you to build up a supply quickly for one or more people.

The Guardian also features a self-cleaning system. With each pump stroke, a portion of the water is used to backflush the membrane and prevent clogging. This design reduces maintenance and maintains flow rate even under heavy use.

Rugged and drop-resistant up to 1.8 m (6 ft), it can treat more than 10,000 litres of water. Its main advantage over a standard pump filter is its ability to eliminate viruses as well, while delivering a high flow rate and automatic backflushing.

The MSR Guardian Purifier Pump offers:

  • Purification against protozoa, bacteria and viruses
  • A flow rate of up to 2.5 litres per minute and a capacity of more than 10,000 litres
  • A robust, self-cleaning system built for the most demanding conditions
