The PU Series pumps are submersible solids handling pumps designed with semi-vortex type impeller for passing solids and stringy materials in residential, commercial, and industrial sewage and site drainage. Available in single-phase, 1/5-1HP, 115V, 230V, and three-phase 1/3-5HP, 208-220V, 460V, and 575V. Corrosive resistant materials of construction. Automatic (A) and Auto-Alternating (W) versions are available in all sizes.
Features
- Semi-vortex, FRP (Fiberglass Reinforced Plastic), impeller passes solids and stringy material without clogging and increases wear resistance when pumpage contains abrasive particles.
- Double inside mechanical seals with silicon carbide faces, running in an oil-filled chamber and further protected by a lip seal, provides for the most durable seal design available.
- Highly efficient, continuous duty, air-filled, copper wound motor with class E, insulation minimizes the cost of operation.
- Built-in thermal & amperage sensing, protector prevents motor failure due to overloading, single phasing (in three phase units), or accidental run-dry conditions.
- Double shielded, permanently lubricated, high-temperature C3 ball bearings rated for a B-10 life of 60,000 hours, extends operational life.
- Utilization of application appropriate FRP & stainless steel components increases corrosion resistance in a wide variety of applications.
Applications
- Residential, commercial, industrial sewage, effluent, wastewater, and site drainage.
- Chemical spill containment.
- Decorative waterfalls, fountains, and fish ponds.
