Grundfos TPE3 100-230 Cast Iron Variable Speed Three Phase Inline Centrifugal Pump with Cast Iron Impeller

Driven by an integrated 5.5 kW drive motor, the TPE3 100-230 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 100 inlet and outlet flanges to streamline plant room pipework installation.

At full duty speed, hydraulic throughput reaches 1960 L/Min with a maximum head threshold of 14.7 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 124 kg.

Power requirements specify a 3 x 380-500 V Three-phase electrical supply rated for 5.5 kW output, with full-load running current measuring 10.5 Amps. Operating liquid temperatures span from -25°C to 120°C across active HVAC circuits. Standardized DN 100 suction and DN 100 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

• 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.
• Class F thermal motor insulation permits continuous operation under elevated fluid temperatures ranging from -25°C to 120°C.
• Equal suction and discharge port diameters enable straightforward inline installation without requiring custom pipe reducer spools.
• Integrated variable frequency converter with PI controller modulates motor RPM dynamically to balance flow demand and lower energy usage.
• 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.
