Pressure sewer networks in residential and industrial developments rely on the Lowara Flygt MF3102.170 HT261 for high-head wastewater transfer. This free-standing grinder pump is placed directly on the bottom of the wet well and features an integrated grinder device for solids reduction. It is engineered for pressurized transport where debris must be macerated before discharge through small-bore infrastructure.
Operating with a 4.4 kW three-phase motor at 415v, the unit achieves a maximum flow of 355 L/Min and reaches a maximum head of 42.5 m. Drawing a rated current of 8.6 Amps, the motor supports up to 30 starts per hour in level-regulated stations. The unit is rated for continuous submerged duty in pressure sewer applications.
Solids reduction is facilitated by an integrated grinder device featuring a Hard-Iron cutter wheel and a stationary cutter plate. This arrangement reduces solid waste to a pumpable consistency, preventing blockages in high-pressure discharge lines. The grinder mechanism is designed for sustained performance when processing wastewater with varied debris concentrations.
Mechanical build features gray iron (GJL-250) major castings and housing for structural stability. The unit utilizes a dual mechanical seal system with corrosion-resistant carbide faces to protect the internal electrical assembly from liquid ingress. Motor protection is provided by Class H insulation and thermal contacts with a 125°C opening threshold.
