IMAS Circulating pump brass - IM25-4S-180B
The IMAS IM25-4S-180B is a three-speed hot water circulator pump designed for circulating clean water and liquids that do not contain chemicals. It is suitable for domestic central heating and air-conditioning systems operating in closed or open pressurized circuits.
The pump features three selectable operating speeds, with power consumption of 38W, 53W and 72W, allowing its performance to be adjusted according to the requirements of the installation. It delivers a maximum flow rate of 4.0 m³/h and a maximum head of 4 m.
The hydraulic pump body is manufactured from brass and incorporates a wet-rotor motor. The motor housing is made of die-cast aluminium, while the impeller is manufactured from technopolymer. The hardened stainless steel motor shaft is supported by graphite bearings and lubricated directly by the pumped liquid.
The rotor protective sleeve, stator sleeve and sealing flange are made of stainless steel. The pump also features a ceramic thrust ring, ethylene-propylene sealing rings and a brass air vent plug.
Designed for hot-water circulation, the IM25-4S-180B can handle liquid temperatures up to 110°C and a maximum operating pressure of 10 bar. It operates from a single-phase 230V/50Hz power supply and features IP44 protection and Class F insulation.
The pump has an installation length of 180 mm, 1½" threaded connections and must be installed with the motor shaft in a horizontal position.
