Product Overview
Generating a maximum operational head limit of 52 m, the TP 80-520/2 single-stage inline pump handles high-friction hydronic distribution loops. Rated flow capacity reaches 1882 L/Min powered by an efficient 18.5 kW electric motor in continuous service.
Constructed with an EN-GJL-250 cast iron casing, the housing body features cataphoresis electrocoating surface treatment for internal corrosion protection. The internal hydraulic assembly contains a precision bronze impeller fitted with bronze wear rings and a maintenance-free mechanical shaft seal. Net product weight measures 187 kg for fixed mounting placement in mechanical plant rooms.
The motor operates on a 415 V three-phase supply rated at 34.5 Amps nominal operating current. Operating liquid temperatures span from -25°C to 120°C under maximum working pressures up to 16 bar. In-line opposite port geometry with DN 80 flanged connections enables mounting directly into straight pipework lines or onto foundation bases.
Motor protection features an IP55 enclosure rating with Class F thermal insulation and integrated PTC thermistors. Top-pull-out structural design enables removal of the motor head and impeller assembly without dismantling the pump housing from connected system pipework lines during scheduled servicing routines.
