The Pedrollo FG-50/125A is a bare shaft EN 733 centrifugal pump for coupling to your own motor. With a 4 kW (5.5 HP) 2-pole motor it delivers up to 1200 l/min and 23.5 m head; it can also be driven by a 4-pole motor for a quieter, lower-head duty.

Pump end only, supplied without motor, coupling or baseplate. Cast iron body and impeller, flanged connections. Counter flanges available on request.

Product overview

The Pedrollo FG-50/125A is a bare shaft single-impeller centrifugal pump built to EN 733 dimensions, with flanged suction and delivery and its own bearing housing. Driven by a 4 kW (5.5 HP) 2-pole motor at 2,900 rpm it covers 300 to 1200 l/min with a working head of 23.5 m down to 13 m. Driven at 1,450 rpm by a 4-pole motor the duty drops to roughly half the flow and a quarter of the head; the 4-pole figures are in the specification table.

A bare shaft pump is the choice when the motor has to be something other than a standard close-coupled unit: a diesel engine on an irrigation or fire set, an ATEX motor, a specific make of motor the site standardises on, or where the pump and motor must be separately serviceable. The pump mounts on a baseplate with a flexible coupling and guard. Pedrollo supply the pump end; we can quote the motor, coupling and baseplate to suit.

Frequently asked questions

Is a motor included?

No. The FG is the pump end only. You need a motor of the size shown (2-pole or 4-pole), a flexible coupling, a coupling guard and a baseplate. Ask us to quote a complete set.

Which motor size do I need?

For 2-pole (2,900 rpm) drive: 4 kW. For 4-pole (1,450 rpm) drive: 0.55 kW. The figures are in the specification table.

Are the flanges included?

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

How does it compare with the F and F4?

Same EN 733 hydraulics. The F and F4 are close-coupled monoblock pumps with the motor built in; the FG is the pump end alone for you to drive.
