Product Overview
Facilities managing wastewater transfer in pressurised systems require specific hydraulic configurations for sewage discharge without external cooling jackets. This Grundfos APG.50.65.3 model is designed for pumping wastewater and sewage in pressurised systems. It is suitable for submerged installation on an auto-coupling system or with a ring stand for free-standing use. The unit has a 3-phase motor.
Constructed from Cast Iron EN-JL1040, the housing surrounds internal components. The CUTTER SYSTEM impeller, manufactured from Cast Iron EN-JL1040, processes solids within the fluid stream. The unit weighs 104 kg and operates in liquids up to 40 °C. Casing follows ASTM 35 B standards. The design employs a vertical configuration to minimize the footprint in wet pits.
The 6.5 kW motor operates on a 415v supply with a rated current of 13.4 Amps. The pump achieves a maximum head of 52 meters and a maximum flow of 526 L/Min through a 50 mm discharge outlet. Power input P1 is 7.5 kW with a rated output power P2 of 6.5 kW. The electrical configuration requires a 3-phase 50 Hz source with a power factor of 0.81.
Thermal protection is provided by Class F insulation with an IP68 enclosure rating. The pump supports installation depths up to 10 meters. Double mechanical shaft seals provide containment with an oil chamber pre-filled with non-toxic special oil. Integrated greased-for-life ball bearings support the shaft.
