Product description
The ESPA Drainex 300 submersible sewage pump is designed for the drainage of sewage and dirty water with solids in suspension, maximum 60mm diameter, and is ideal for operation in septic tanks and small purifying installations.
The Drainex 300 is suitable for use in household and residential, industrial and agricultural environments and in general construction.
They have been designed using highly abrasion-resistant materials, making them look very compact and sturdy. The pump body, discharge body, suction body and impeller are constructed from cast iron, with a Stainless Steel motor shaft and detachable base, with silicon carbide and graphite mechanical seal. The cast iron vortex impeller allows free passage of particles in suspension of 65mm diameter maximum.
All parts in contact with water are coated with an anti-corrosion treatment. The oversized motor makes them excellent for prolonged, worry-free operation.
The water cooled motor type is asynchronous with two poles, has IP 68 protection, Class F insulation and allows continuous operation. The single phase version has built-in thermal protection and capacitor.
The Drainex 300 Series are available in three versions, manual, automatic with attached float switch and three-phase – all models have a 2½ inch female BSP threaded horizontal discharge.
