Pedrollo FCR 15-30 Horizontal Stainless Multistage Pump

Pedrollo FCR 15-30 pump explained

The Pedrollo FCR 15-30 is a family of horizontal multistage centrifugal pumps made of stainless steel AISI 304, rated up to 800 l/min (48 m³/h) and up to 120 m of head, with a 12 bar working-pressure limit. It includes the FCR 15, FCR 22 and FCR 30 sizes, each with several stage counts. Seven Star LLC supplies the FCR in Oman and the GCC as an independent supplier in Muscat.

In a code such as FCR 22/4, the 22 is the hydraulic size (nominal flow class) and the 4 is the number of stages. Some codes carry an R after the stage count (FCR 15/2R, FCR 15/3R, FCR 30/2R), which the datasheet lists as separate models with their own motor power, so quote the full code. The datasheet lists FCR 15/2R at 2.2 kW with 44 m, FCR 15/5 at 7.5 kW with 120 m, FCR 22/2 at 3 kW with 39 m, FCR 22/5 at 7.5 kW with 98 m and FCR 30/4 at 7.5 kW with 80 m.

FCR 15-30 technical specifications

The values above come from the manufacturer technical data for the series. Individual models inside the FCR 15-30 range differ in power, head and current, so always confirm the exact model code before ordering.

How the FCR 15-30 works and what limits it

All wetted parts, including pump housing, impellers, diffusers and cover, are stainless steel AISI 304, the shaft is AISI 431 and the motors are three-phase IE3 with IP 55 protection. Operating limits are suction up to 7 m, liquid -15 to +90 °C, ambient up to +40 °C and 12 bar. The manufacturer notes silent operation and energy efficiency as the main advantages.

In a multistage centrifugal pump the liquid passes through several impellers in series, each stage adding head to the stage before it. The number of stages therefore sets the head, while the impeller width and motor power set the flow. The stage count is part of the model code, so a longer code number means a higher head at the same pipe size. Stable pressure, quiet running and a compact footprint are the practical benefits compared with a single-stage pump of the same head, and the pump gives its best efficiency when operated close to the middle of its curve.

FCR 15-30 models and performance data

The heads in this table are read from the first point of the manufacturer 50 Hz performance table and fall as flow increases, so use the full curve for the real duty point. Where a 60 Hz version is needed, ask us: the manufacturer states that 60 Hz motors are available on request for many models.

Where the FCR 15-30 fits: related Pedrollo pumps

Compare with the vertical HT-PRO, which has similar stainless construction and reaches 160 m, and the MK vertical pumps for smaller domestic duty. The VSP builds an FCR hydraulic into a variable-speed unit.

Selecting a FCR 15-30 pump: checklist

• Select size 15, 22 or 30 from the flow
• Select the stage count from the head needed
• Check the 12 bar working-pressure limit against the shutoff head plus inlet pressure
• Confirm the liquid temperature between -15 and +90 °C
• Three-phase supply required, IE3 motor

Installing and maintaining the FCR 15-30

Place the pump on a level, rigid base and tighten the anchor bolts evenly so the pump body is not stressed by the piping. Support the suction and delivery pipes independently, fit isolating valves on both sides to allow servicing, and add a non-return valve on the delivery side. Prime the pump fully before starting, because the stages must be filled with liquid to avoid running dry. Check the motor rotation on three-phase units, fit overload protection matched to the nameplate current, and make sure the pump never runs against a closed delivery for more than a short time. For pressure boosting, size the tank and pressure switch (or use a variable-speed controller) so that the number of starts per hour stays within the motor limit.

FCR 15-30 applications in Oman and the GCC

In Oman and the GCC the FCR can feed building boosting sets, industrial wash systems, irrigation systems with an autoclave tank and cooling or process water where stainless steel is preferred for its corrosion resistance. For hotel and commercial buildings, the horizontal layout fits in plant rooms with limited height.

In hotels, hospital blocks and industrial sites around Muscat, Sohar and Salalah, multistage pumps run for long hours at steady pressure. Rooftop tanks can warm the water significantly, so check the temperature limit, and keep plant rooms ventilated. Chlorinated or desalinated supply water is normally acceptable only if the wetted material suits it, so state the water source on your enquiry.
