IGDL 50-16-1.1 (3~400 V) – multistage in-line circulation pump
The IBO IGDL 50-16-1.1 pump is an efficient, multistage pump for cold and hot water, intended for supplying and boosting pressure in water, heating, and industrial systems wherever reliable water circulation across a wide temperature range is required.
For whom
- Installers and contracting companies – a proven solution for constructing and modernizing water, heating, and HVAC systems in residential and commercial buildings, ensuring stable operating parameters.
- Managers of multi-family residential buildings and commercial facilities – effective water pressure boosting and user comfort in high-rise buildings and extensive hot and cold water systems.
- Industry and manufacturing plants – reliable circulation of fluids in process systems, cooling circuits, and water supply systems for boilers, using a pump with high energy efficiency.
- Farmers and agricultural holdings – can be used in irrigation systems, water supply systems, and systems supporting the operation of technological equipment.
Application
- Water supply and pressure-boosting systems in high-rise buildings, supplying water supply installations and domestic water distribution systems.
- HVAC and heating systems, including the circulation of cold and hot water in central heating and domestic hot water circuits, cooperation with heat exchangers and air handling units.
- Industrial circulation systems, process water circulation systems, and systems supporting the operation of production equipment.
- Agricultural irrigation, watering systems, and the transport of clean water from reservoirs, tanks, and storage systems.
The pump is suitable wherever reliable circulation of clean water is required for domestic, industrial, heating, and irrigation applications. The pump does not treat water; when it is used for applications requiring potable water, we recommend ensuring appropriate water treatment.
IGDL 50-16-1.1 features – description and technical data
The pump is designed to operate in systems requiring both high efficiency and resistance to elevated fluid temperatures. It can handle cold and hot water, provided that the medium is free of fibers and solid particles, and that the hot water is soft water with a low content of dissolved calcium and magnesium compounds.
Construction and materials
The construction is based on durable materials that ensure long-lasting, trouble-free operation. The pump casing, diffuser, intermediate wall and rear cover are made of AISI 304 stainless steel, ensuring high corrosion resistance and enabling safe operation with domestic water, including domestic hot water (DHW) circulation systems. The motor housing is made of aluminium, allowing the unit to combine good heat dissipation with relatively low weight.
- Motor housing: aluminium.
- Rear cover, intermediate wall, diffuser, pump casing: AISI 304 stainless steel.
- Pump casing support: steel.
- Mechanical seal: graphite, silicon carbide, FKM seal (resistant to higher temperatures and the effects of many fluids).
Thanks to the use of a high-quality mechanical seal with graphite and silicon carbide components and an FKM seal, the pump is adequately protected against leaks and designed to operate with elevated fluid temperatures while maintaining a high level of tightness.
Motor and electrical parameters
The pump is equipped with a high-efficiency IE3 electric motor, which results in lower energy consumption while maintaining the required operating parameters. The motor has an IP55 protection rating, providing effective protection against dust ingress and water jets, and insulation class F, allowing operation at elevated winding temperatures. The motor's operating mode is intended for continuous applications in typical water and heating systems.
- High-efficiency motor: efficiency class IE3.
- Power supply: 3~400 V, 50 Hz.
- Protection rating: IP55.
- Insulation class: F.
- Operating mode: continuous.
Operating conditions and performance parameters
The pump is designed to operate with clean water free of fibres, sand and other solid particles, which is crucial for protecting the hydraulic components and seals. When operating with hot water, soft water is required, which reduces the risk of limescale deposits and extends the service life of the pump and installation.
- Medium: clean water, free of fibres and solid particles.
- Hot water: soft water required (low content of dissolved calcium and magnesium compounds).
To ensure trouble-free operation and prevent cavitation, the minimum inlet pressure on the suction side must be maintained according to the fluid temperature: for temperatures up to 75°C – 0.4 bar (4 m water column), and at 90°C – 0.7 bar (7 m water column). The inlet pressure and installation height relative to the water level must always be verified at the installation design stage, taking pressure losses and the specific characteristics of the supply source into account.
Installation and operation
The pump should be installed to ensure easy access for servicing, stable mounting, and proper system venting. Before starting the system, make sure that the medium meets the manufacturer's requirements and that the required minimum inlet pressure values on the suction side are maintained. The use of shut-off valves, mesh filters, and protective fittings selected according to the requirements of the specific installation is recommended.
For long-term operation, periodic system inspections, leak checks, and inspections of the seals and the motor's electrical parameters are recommended. Regular maintenance in accordance with the operating manual helps maintain the device's high hydraulic and electrical efficiency for many years.

Frequently asked questions (FAQ) – IGDL 50-16-1.1 circulating pump
What types of installations is the IGDL 50-16-1.1 pump best suited for?
The pump is recommended for water-supply installations, pressure boosting in high-rise buildings, HVAC and heating systems, including central-heating and domestic-hot-water circuits, as well as industrial circulation systems using clean water as the medium.
Can the IGDL 50-16-1.1 pump operate with hot water, including in a domestic hot-water system?
Yes. Thanks to its construction featuring AISI 304 stainless steel components and a seal resistant to elevated temperatures, the pump is suitable for hot-water circulation, including domestic hot-water systems, provided that the water-quality and hardness requirements are met. However, the pump is not a water-treatment device.
What are the requirements for inlet pressure on the suction side?
For a fluid temperature of up to 75°C, the minimum inlet pressure on the suction side is 0.4 bar at a 4 m water column height. For a temperature of 90°C, the required minimum inlet pressure is 0.7 bar at a 7 m water column height.
How should the IGDL 50-16-1.1 pump be maintained during operation?
Proper operation requires using clean water, periodically checking the filters, system tightness, and the motor's electrical parameters, as well as following the instructions in the manual. For hot-water installations, it is advisable to monitor the water hardness and the condition of the seals.
