Koshin submersible pump with 50 mm nozzle for pumping muddy or dirty water with sand. Delivery 325 l/min, stainless steel housing.
A high quality electric submersible pump from the well-known Japanese manufacturer Koshin. It can work with muddy and dirty water with impurities of solids and sand with fraction diameter up to 6 mm.
Water is discharged through a 50 mm (2 in.) diameter outlet pipe.
The pump can be used in daily life for lifting water from wells, manholes, aquariums, fish farming and industry.
The motor is an asynchronous motor with capacitor, which ensures excellent water delivery performance and long service life of the device.
The pump has a robust and corrosion-resistant stainless steel housing and its compact size makes it easy to install in hard-to-reach places such as small wells and manholes.
Thanks to its excellent performance of 325 l/min, it can lift water up to a height of 14 m.
A 10 m electric cable is used for connection to the mains.
Please note that the shaft seal is the most important waterproof part of the pump, which is sealed with oil. It is recommended to use SHELL VITREA OIL 32. Check the oil after 1000 hours of pump operation (approximately every 3 months). If the oil is contaminated or water has penetrated, the oil seal (mechanical seal) must be replaced.
In addition to the pump, the scope of delivery also includes a coupling.
