PROPELLER PUMPS

The IRON propeller pump series QT/QTe is primarily operating in anti-heeling applications. The pump job is signified by bi-directional operation, low head and flow variating from smaller to larger capacities.
The QT anti-heeling pump series from IRON are based on the propeller principle, allowing to reverse the rotation hence controlling the flow-direction from side to side of the vessel. This by means of motor controls, and only one valve, simplifying the lay-out of the anti-heeling system significantly.

Since IRON Pump A/S first pioneered the anti-heeling pump back in 1952, the company has supplied several thousand anti heeling pumps for all kinds of anti-heeling applications. Setting standard for not only quality but for sure also reliability and flexibility in the market has led to the QT pumps by IRON can be found in almost all kinds of larger vessels throughout the world.

Being a ship designer, AHS manufacturer, shipyard engineer or the-like, take the advantage of including the QT anti-heeling pump as 3D part in your system design, and discover the possibilities the QT design offers regarding installation flexibilities. The 3D parts are available in most used formats.


QTe
The QTe is the latest developed edition to the QT series. It has been designed to meet market requirements for improved performance, small foot-print and still be easily maintained.

The motor has been placed horizontally on top, driving the pump with belts. The hydraulic part is easily accessible by removing the two intermediate sections, placed in both ends. This enables access to the wear-parts such as belts, bearings, and the mechanical seal, without removing the motor or lifting the pump from its bed.

The QTe design makes it possible to fit in spaces where other anti-heeling pumps are too large. The compact design both in height and in length between flanges makes it ideal for optimizing deck space in newbuilds, and for retrofitting in areas where no other pump fits, saving cost of pipe and valve modifications. 

The simple design not only provides a rigid and robust construction but also facilitates quick inspection and service. The wide use of standard components ensures reduced cost of spare parts. The belt drive allows variations in gear ratio hence adapting pump configuration to suit the performance requirements best possible way. It also allows simple modification in case the demands should change over time, only by changing belt and cam wheel, and perhaps the number of impellers.

Options
• Flanges configuration available in DIN, ANSI and JIS.
• Pressure gauge panel
• Enhanced motor cooling
• Service-kits, consisting of belt, bearings, seals and gaskets.
• Venting device for removing air inside the pump
• Leakage indicator

Easy. The compact in-line design allows for easy service and for installation in narrow spaces, like in between the frames or stringers.


Low Risk. The belt drive design results in a compact pump with low risk and low cost operation, throughout the pump’s entire lifespan. If a mechanical seal fails, the pump can easily be repaired and up and running again in no time with as little as a service kit. The entire pump can be serviced leaving the the main installation or motor untouched.


Efficiency. All standard motors can be mounted to achieve best possible efficiency and accommodate customer demands and preferred brands. Motors can be supplied for, and delivered with, frequency converters for further improvements.


As of today, 2021, we have supplied more than 3000 QT’s into operation on:


• Ferries
• Ro-Ro’s
• Cruise ships
• Container ships
• Heavy lifters
• Others

With an IRON anti-heeling pump, you step up securing that your cargo operations will be performed without interruptions due to heeling and trimming.
