Calpeda BT61 03C15T - BTM 61E 230/50 HZ with Tropicalize motor

Model: Calpeda BT61 03C15T – BTM 61E 230/50 HZ (Tropicalized Motor)

The Calpeda BT61 03C15T – BTM 61E 230/50 HZ is a close‑coupled peripheral (regenerative) pump from the reliable Calpeda T Series, designed for clean liquid applications requiring compact size and high pressure relative to flow. This pump features a turbine (peripheral) impeller and a patented compact construction with a single‑piece motor casing and integrated pump wall.

The BTM 61E model is engineered to prevent water from entering the motor from the outside, improving durability and operational safety. Its reduced dimensions make it especially suitable for cooling systems, air‑conditioning equipment, circulation systems, and boiler feed applications where space is limited.

Designed for clean, non‑abrasive, non‑explosive, and non‑aggressive liquids, the Calpeda T Series peripheral pump is commonly used for pressure boosting in water networks (in accordance with local regulations) and for continuous‑duty industrial and commercial applications.

The pump is equipped with a 2‑pole induction motor (50 Hz) and is available in three‑phase 230/460 V or single‑phase 115 V / 230 V versions, with thermal protection and an integrated capacitor inside the terminal box. The motor features Class F insulation and IP44 protection, ensuring reliable operation under continuous duty conditions.
