Raw sewage transport in small-scale infrastructure stations is the primary application for the Lowara Flygt MF3069.170 HT250. This free-standing grinder pump is installed directly on the bottom of the wet well and features an integrated grinder device for solids reduction. It is specifically suited for sewage conveyance where organic waste requires maceration before discharge through pressurized piping.
Hydraulic delivery is driven by a 2.4 kW three-phase motor producing a maximum head of 35 m and reaching a maximum flow of 270 L/Min. Operating at 415v with a rated current of 5.1 Amps, the motor supports up to 15 starts per hour in level-controlled utility wells. The unit is designed for reliable submerged service in semipermanent installations.
Solids reduction is achieved through an integrated grinder device utilizing a martensitic stainless steel cutter wheel and cutter plate. This arrangement reduces incoming debris to a pumpable consistency, preventing blockages and ensuring continuous operation. The grinder mechanism is engineered for sustained performance when processing sewage with varied organic content.
The pump features gray iron (GJL-200) major castings and housing for mechanical stability. A dual mechanical seal system with carbide faces protects the internal stator assembly from moisture ingress. Motor protection includes winding-embedded thermal contacts with a 125°C opening threshold for automatic safety shut-off during overheating events.
