This new model is based on the existing 150‑315 and 200‑315 designs and shares all standard components, except for a newly designed investment‑cast pump casing and impeller. The maximum available motor power is 90 kW (4‑pole). By using the same Ø70 mm mechanical seal and existing O‑rings, no additional spare parts are required for customers already operating MFP3 & MCP3 pumps.
Designed with efficiency in its DNA, the 125‑315 delivers MEI ≥ 0.4 and reaches efficiencies close to 80% across a wide operating range of 150–400 m³/h and 25–50 m head (50 Hz, water), while maintaining a flat efficiency curve even with trimmed impellers.
The pump is available for sale immediately, with deliveries starting in April 2026. Prices, curves, and technical documentation will be included in CAPDATA version 46, released on Monday, January 26, 2026.
