Calpeda CTM 61 0.33kW Single Phase Periphreral Bare Pump (Max 40LPM/400kPa)

The Calpeda CTM 61 Peripheral Pump is a compact, high-pressure pump designed for transferring clean water in residential, commercial, and light industrial applications. With its peripheral impeller design, the pump can generate relatively high pressure at low flow rates, making it ideal for boosting pressure, small water supply systems, and circulation duties where space is limited.

Featuring Calpeda’s patented compact construction, the CTM 61 integrates the pump and motor within a single-piece casing for improved durability and reliability. The pump body is manufactured from robust cast iron with a brass impeller and mechanical seal, providing excellent resistance to wear while maintaining consistent performance.

Operating on single-phase 230V power, the CTM 61 includes a built-in thermal protector and capacitor inside the terminal box for safe and reliable operation. Its compact footprint and quiet operation make it particularly well suited for installation in pressure boosting systems, cooling equipment, and machinery where reliable water circulation is required

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
