– Guaranteed suction height of 8 meters*.
– Silicon carbide mechanical seal: 4-5 times more resistant than standard carbon ceramic mechanical seal.
– Ductile iron (FCD) for impeller & volute casing provides 10 times more erosion resistance than cast iron.
* At 0 m above sea level
- Durability The housing of the Koshin STH-50X motor pump is made of an aluminium alloy. The material is not subject to corrosion, temperature influences or deformation, which increases the service life of the device.
- Efficient operation. The four-stroke engine with an output of 2.9 hp helps to pump 600 litres of liquid per minute.
