Elpumps | Free-flow sewage pumps

Elpumps free-flow (Vortex) submersible pumps provide a free flow-through passage of solids and liquids, minimizing the risk of jamming and low performance. Tough, durable, corrosion-proof materials make these pumps ideal for a wide range of dirty water pumping applications. Each pump is fitted with a low-consumption electric motor with overload protection and a float switch for automatic water level control.

Stylish design, improved technology and innovative materials are the main features behind the new Elpumps NEPTUN free-flow (Vortex) pumps, engineered for easy use and extreme reliability. As the Vortex system allows dirty water drainage without fear of the impeller clogging, Elpumps NEPTUN water pumps can be used for domestic and industrial applications where the water, such as groundwater, sewage water or other types of surface water, contains suspended solids of up to 30 mm.

FEATURES AND BENEFITS

• Powerful 1200W motor
• Flow rate of up to 25,000 liters/hour
• Maximum delivery head of up to 11 meters
• Durable, massive construction
• Able to pass solids of up to 35 mm in diameter
• Vertical outlet

APPLICATION

• Reliable pumping of sewage with dirt particles up to 35 mm in size
• Draining of slightly dirty water from construction sites
• Automatic draining of dirty water from cesspools, wells, tanks or reservoirs
• Flood irrigation in greenhouses, horticulture and small-scale agriculture
• Water supply for livestock farming
• Emergency draining of flooded areas or rooms
• Lowering groundwater
• Rainwater harvesting

STRUCTURE

The pump motor casing and shaft are composed of INOX stainless steel, the hydraulic case is constructed of cast iron or INOX steel, and the impeller is made of high-grade, corrosion-proof NORYL PPO polymer, gray cast iron or INOX steel. The shaft is jointly sealed with a spring-loaded seal ring (gasket) and a modern slide-ring axial seal.
