Confronting the immense demands of deep submerged installations, the UNILIFT AP50B.50.11.3V Unilift AP 35B and 50B pumps are single stage pumps with a vortex impeller designed to transport high-volume wastewater challenges. This commercial submersible effluent pump operates flawlessly in extreme environments, ensuring industrial facilities maintain continuous fluid evacuation without facing catastrophic flow blockages.
Constructed of premium EN 1.4301 AISI 304 stainless steel, the protective housing delivers superior resilience alongside a heavy-duty composite base plate. The intelligent architectural layout includes an intermediate oil chamber pre-filled with safe non-toxic special oil, actively preserving the integrity of the crucial double shaft seal from highly aggressive groundwater transfer scenarios.
Examining hydraulic throughput, the large 50 mm free passage vortex impeller effectively transports dense suspended solids and dirty water to secure sustained velocity paths. This commercial-grade mechanical configuration perfectly optimizes multi-inlet circulation loops, pushing an approximate 14 m maximum head and roughly 480 L/Min maximum flow out of a 50 mm discharge port.
Addressing intense operating loads, the heavy-duty motor features an advanced insulation class F rating for superior heat dissipation. Driven by a powerful 1.31 kW Three Phase 415v electrical architecture, this system drastically reduces ongoing maintenance overhead while ensuring exceptional reliability across the most rigorous commercial duty cycles.
Features
- Standard deployment utilizes long-life deep-groove greased-for-life ball bearings to handle heavy rotational loads
- Delivered with a standard 10 m mains cable ready for manual electrical integration
- Engineered for applications requiring an external thermal protection mechanism
- Designed strictly as a manual pump without an automated level switch component
- Verified for maximum aquatic defense by an IP68 enclosure class rating
