Product Overview
Driven by an integrated 15 kW drive motor, the TPE3 80-520 single-stage inline centrifugal pump provides continuous liquid circulation across commercial HVAC networks, chilled water loops, and facility hydronic circuits. Its in-line structural layout incorporates matching DN 80 inlet and outlet flanges to streamline plant room pipework installation.
At full duty speed, hydraulic throughput reaches 2052 L/Min with a maximum head threshold of 37.5 m. Casing construction uses robust electrocoated cast iron (EN-GJL-250) to resist internal surface oxidation. Fluid transfer is driven by a Cast iron impeller paired with an industry-standard BQQE shaft seal. Physical net weight is 140 kg.
Power requirements specify a 3 x 380-480 V Three-phase electrical supply rated for 15 kW output, with full-load running current measuring 26.7 Amps. Operating liquid temperatures span from -25°C to 120°C across active HVAC circuits. Standardized DN 80 suction and DN 80 discharge flanged ports facilitate direct line insertion.
The drive motor is housed within an IP55 rated enclosure featuring Class F winding insulation to protect against thermal stress. Built-in frequency control with an integrated PI controller enables automatic variable speed adjustment according to active hydronic load. Maintenance operations utilize a service-friendly top-pull-out design, allowing complete rotor disassembly while the cast iron housing remains fixed in the pipe run.
Features
- Top-pull-out structural layout enables complete drive head and impeller extraction without disconnecting the pump casing from system piping.
- High-efficiency motor design delivers optimized hydraulic throughput with minimal electrical power consumption across variable duty cycles.
- EN-GJL-250 cast iron volute housing provides robust pressure containment up to 16 bar in demanding hydronic circulation loops.
- Corrosion-resistant Cast iron impeller rotor is precision-balanced to minimize operational vibration and extend bearing lifecycle.
- Standardized DN 80 flanged connections comply with EN 1092-2 for seamless drop-in integration into commercial pipe headers.
- Maintenance-free BQQE mechanical shaft seal prevents fluid leakage and maintains seal integrity under elevated working pressures.
- IP55 motor enclosure protection guards internal electrical components against ambient dust accumulation and water splash ingress.
