Flygt Concertor Smart Wastewater Pumping System

Overview

The Flygt Concertor is the world’s first wastewater pumping system with fully integrated intelligence, engineered by Xylem to replace the traditional separation between pump, motor and control cabinet with a single self-optimizing unit. Built around an IE4 premium-efficiency motor, Xylem’s patented second-generation N-hydraulics and an onboard power electronics module, the Flygt Concertor senses real-time operating conditions inside the wet well – flow, head, and clogging risk – and automatically adjusts pump speed and cleaning cycles to match. The result is a pumping system rated across the 2.2–7.3 kW power band that field trials show can cut station energy consumption by up to 70 percent while virtually eliminating unplanned callouts for rag and debris blockages.

Working closely with plant engineers in the region, Seven Star LLC proudly supplies the Flygt Concertor smart wastewater pumping system to municipal utilities, EPC contractors, and industrial operators across the Sultanate of Oman and the wider GCC. Every unit shipped from our Muscat facility is backed by Xylem-certified spare parts availability, full commissioning support, and local technical documentation, giving asset owners in Muscat, Sohar, and Salalah a single accountable source for both the pump and its integrated controls.

Operating Principle

Unlike conventional wastewater pumps that pair a fixed hydraulic profile with an external variable-frequency drive, the Flygt Concertor pump embeds its power electronics directly inside the motor housing, communicating continuously with Xylem’s adaptive control algorithm. The pump reads torque and current signatures at the impeller in real time; when the algorithm detects early signs of ragging or clogging, it triggers the second-generation N-technology self-cleaning function – a brief reverse-and-forward pulse sequence that clears the flow passage without operator intervention. Because the hydraulic response curve is generated in software rather than fixed in casting geometry, a single Concertor unit can be reconfigured to match a wide performance envelope, reducing the spare-pump inventory a utility needs to keep on the shelf by up to 80 percent.

This closed-loop, sensor-driven operation has direct practical consequences for the wet well itself: because clogging events are pre-empted rather than reacted to, sump walls stay cleaner between maintenance visits, cutting vacuum-truck cleaning costs by as much as 80 percent, and station cabinets can shrink by up to 50 percent since much of the control logic that once required external panel space now lives inside the pump. For plant engineers, that translates into fewer confined-space entries, lower lifecycle cost, and a pumping asset that reports its own health rather than waiting to be diagnosed after a failure.

Engineering Design of the Flygt Concertor

The Flygt Concertor pump is built on a cast-iron submersible volute housing with a hardened, adaptive N-hydraulic impeller sized to pass large solids without pre-screening, matching the raw, unscreened sewage conditions typical of GCC collection networks. The stator, integrated power electronics, and cooling jacket are sealed within a single IP68-rated enclosure, removing the external junction box and terminal points that are usually the first failure mode in a corrosive wet-well atmosphere. A tandem mechanical seal arrangement with an intermediate oil chamber protects the motor from moisture ingress, while a stainless-steel lifting handle and standard guide-rail coupling footprint allow the unit to be installed or withdrawn from grade level without dewatering the station.

Interface and communication are handled through the Concertor’s onboard control top or, on system-level installations, through the companion Concertor XPC station manager, which presents pump status, energy consumption and alarm history on a local HMI and can gateway that data to a SCADA network or Xylem’s remote monitoring cloud. Cabling is simplified to a single power-and-communication run per pump, and the electronics accept a wide voltage range suitable for the variable grid conditions found across Oman’s industrial and municipal networks. This design lets contractors commission a Concertor DP, N, or XPC variant using the same mechanical footprint, simplifying spares planning for multi-station projects.

Key Features

The Flygt Concertor pump concentrates a decade of Flygt wastewater engineering into a single field-proven package. Its standout capabilities include:

• IE4 premium-efficiency motor integrated with onboard power electronics, delivering up to 70 percent lower energy consumption than conventional fixed-speed wastewater pump stations.
• Second-generation adaptive N-hydraulics with self-cleaning pulse sequencing that keeps the flow passage clear of rags, wipes, and fibrous solids without manual intervention.
• Real-time condition monitoring of torque, current, insulation resistance, and vibration, enabling predictive maintenance instead of reactive callouts.
• Flexible performance envelope that lets one Flygt Concertor pump size cover a broad flow-head range, cutting spare-inventory requirements by up to 80 percent.
• Compact IP68-rated sealed enclosure that eliminates the external terminal box and reduces control cabinet footprint by up to 50 percent.
• Standard guide-rail coupling and lifting handle for rapid installation and withdrawal without dewatering the wet well.
• Compatibility with the Concertor XPC station manager and Xylem’s remote monitoring platform for SCADA integration and cloud-based fleet oversight.
• Tandem mechanical seal with oil-barrier chamber, rated for continuous submersible duty in raw, unscreened municipal and industrial wastewater.

Industrial Applications

The Flygt Concertor pump is specified wherever raw or partially screened wastewater must be lifted reliably with minimal maintenance access, including municipal sewage lift stations, combined sewer overflow structures, industrial effluent sumps, and pumping stations serving hotel and residential developments along the coast. Its self-cleaning hydraulics make it particularly well suited to stations with intermittent flow and high rag content, a common condition in fast-growing GCC urban districts where informal solids disposal into the sewer network is still a challenge for utility operators.

With fast quotation turnaround and technical support, Seven Star LLC distributes and supports the Flygt Concertor pump across district cooling plant drainage systems, RO desalination pretreatment sumps, hospital and hospitality wastewater networks, and municipal projects within the Sohar and Salalah economic zones.
