Full Description

Product overview

The Pedrollo F 65/250B is a 37 kW (50 HP) single-impeller centrifugal pump on a 400 V three-phase supply, built to EN 733 dimensions with flanged suction and delivery. It covers 400 to 2500 l/min with a working head of 87 m down to 62 m across that range, at 2,900 rpm.

Standardised dimensions mean it drops into an existing EN 733 installation from any manufacturer. The close-coupled monoblock design puts the impeller directly on the motor shaft, so there is no coupling or baseplate to align. Suits water supply and pressure boosting in commercial buildings, HVAC and cooling circulation, irrigation and agricultural supply, and industrial transfer of clean water. Install indoors or under cover.

Frequently asked questions

What does EN 733 mean?

EN 733 (formerly DIN 24255) sets the dimensions, flange sizes and duty points for standardised centrifugal pumps. A Pedrollo F of a given size fits the same pipework as any other EN 733 pump of that size.

Are the flanges included?

No. Counter flanges, nuts, bolts and gaskets are available separately — ask us when ordering.

What is the -I version?

The same pump with the body cast in AISI 316 stainless steel and a stainless impeller, for aggressive, treated or sea water.

What is the difference from the F4?

The F runs at 2,900 rpm (2-pole) for higher head. The F4 runs at 1,450 rpm (4-pole) for quieter running and lower NPSH at lower head.
