Product Overview
Safeguarding basements, garages, and low-lying residential areas from sudden ingress is the primary objective of this automatic dewatering unit. It provides a specialized defense for building services where liquid removal is required during high-ingress storm events or flooding. The integration of a flexible float switch allows for autonomous liquid removal from subsurface collection pits without the need for constant user oversight.
Operating performance is anchored by a 0.53 kW / 240v single-phase motor that pulls a rated current of 2.0 Amps. This system achieves a maximum head of 11 m and sustains a high-volume flow rate of 250 L/Min for rapid area clearance. The asynchronous motor supports continuous duty cycles, ensuring the pressure behavior remains stable during prolonged cleanup operations in domestic dewatering installations.
Fluid transfer is conducted by a single impeller design engineered to facilitate the movement of water containing suspended particles up to 6 mm in diameter. The hydraulic configuration balances high-volume output with the precision necessary for clearing shallow floor ingress or emptying subsurface sumps efficiently. The top-mounted 2-inch DN hose tail facilitates a streamlined connection to standard drainage lines to ensure maximum volumetric displacement.
Mechanical resistance is provided by a coated AISi12 aluminum hydraulic body paired with a 201-grade stainless steel motor shaft for long-term corrosion prevention. Internal safety components feature graphite-ceramic mechanical seals and an auto-resetting thermal overload protector integrated into the Class B insulated motor windings. Rated for IPX8, the assembly supports safe and indefinite submerged deployment at practical depths reaching 7 metres.
FEATURES
- Automatic flexible float switch oversight enables unattended water level control and essential dry-run motor protection.
- Coated AISi12 aluminum hydraulic housing provides high mechanical strength and impact resistance in submerged duty.
- Specialized single impeller configuration facilitates the passage of small suspended solids up to 6mm without blockage.
- Integrated auto-resetting thermal overload protector safeguards the internal motor windings from accidental over-temperature.
- Graphite-ceramic mechanical seal arrangement creates a high-reliability barrier against liquid ingress to the stator.
- 201-grade stainless steel motor shaft offers enhanced durability and resistance to corrosive chemical attack.
- Top-mounted 2" DN universal hose tail discharge supports rapid connection to high-volume dewatering hoses.
- IPX8 protection rating ensures hermetic sealing for safe submerged operation at depths up to 7 metres.
