Calpeda CTM 60 0.33kW Single Phase Periphreral Bare Pump (Max 40LPM/400kPa)

The Calpeda CTM 60 Peripheral Pump is a compact, high-pressure surface pump designed for transferring clean water in residential, commercial, and light industrial applications. Built with a peripheral impeller design, this pump is capable of generating strong pressure at relatively low flow rates, making it ideal for pressure boosting, water transfer, and circulation systems where consistent pressure is required.

Manufactured by Calpeda in Italy, the CTM 60 features a durable cast iron pump casing and a precision-machined brass impeller for reliable performance and long service life. Its close-coupled construction integrates the pump and motor into a compact unit, reducing installation space while improving overall reliability. The small footprint makes this pump particularly suitable for installations inside equipment, machinery, or tight plant rooms.

Powered by a 0.33kW single-phase motor, the CTM 60 operates on standard 230V power and includes built-in thermal protection to safeguard the motor from overload. Designed for continuous duty operation, it delivers dependable performance in pressure boosting systems, water supply systems, cooling equipment, and light circulation applications.

COMPARISON

• CT vs CTM
  • CT models are three-phase pumps (230/400V)
  • CTM models are single-phase pumps (230V) with an internal capacitor and thermal protection.
• 60 vs 61
  • Refers to the nominal impeller diameter used in the pump.
  • Performance curves are extremely similar, but the 61 version generally provides slightly higher head characteristics across the curve
