Siemens Dematic NMD 20 110Z 3 4Hp Centrifugal Pump

Calpeda NMD 20/110Z/A is a close-coupled, three‑phase centrifugal pump with a cast‑iron housing built for reliable water handling in residential and light commercial service. The 0.55 kW motor (about 3/4 HP) runs on 230/400 V, 3‑phase at 50 Hz (approximately 2900 rpm), with a 60 Hz variant available under the same model family at 254/440 V, 3‑phase. The unit uses threaded inlet and outlet connections sized 1-1/4 in and 1 in respectively, enabling straightforward installation on standard piping. As a beltless, direct‑drive design, it couples the impeller directly to the motor and features a cast‑iron pump casing and lantern bracket for durability. In performance terms, the NMD 20/110Z/A delivers up to around 39 m of head and can move up to about 70 L/min (4.2 m³/h) under typical operating conditions, making it suitable for circulating and transferring clean water in small to mid‑size installations.
