The Calpeda GXRM 11 is a compact stainless steel submersible drainage pump designed for efficient removal of clean or slightly dirty water in domestic, commercial and light industrial applications. Built from chrome-nickel AISI 304 stainless steel with a single open impeller, the pump provides excellent corrosion resistance and dependable long-term performance in wet environments.
Powered by a 0.37 kW single-phase motor, the GXRM 11 delivers flow rates up to approximately 200 litres per minute with a maximum head of about 11 metres, making it ideal for draining flooded areas, tanks, pits, basements and rainwater systems. The motor operates at around 2900 rpm and is cooled by the pumped liquid, enabling continuous duty operation while maintaining safe temperatures.
The integrated float switch provides automatic start and stop based on water level, helping prevent dry running and reducing manual supervision. A double mechanical seal with oil chamber protects the motor against water ingress, while thermal protection enhances reliability and service life.
Suitable for clean water with suspended solids up to approximately 10 mm, the GXRM 11 can be used for draining rooms, sumps, ponds, rainwater collection pits and irrigation storage. With IPX8 protection for continuous immersion and a maximum immersion depth of around 5 metres, it is engineered for dependable operation in demanding conditions.
