Description
IGDL 50-19-1.5 (3~400 V) – multistage in-line circulation pump
The IBO IGDL 50-19-1.5 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 contractors – a proven solution for constructing and modernising 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 ensuring user comfort in high-rise buildings and extensive hot and cold water systems.
- Industry and manufacturing plants – reliable circulation of media in process systems, cooling circuits and systems supplying water to boilers, using a pump with high energy efficiency.
- Farmers and agricultural holdings – suitable for use in irrigation systems, water supply systems and systems supporting the operation of process 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, as well as operation with heat exchangers and air handling units.
- Industrial circulation systems, process systems for circulating process water 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 is not a water treatment device; when it is used for purposes requiring potable water, we recommend ensuring appropriate water treatment.
IGDL 50-19-1.5 features – description and technical data
The pump was designed for use in systems requiring both high efficiency and resistance to elevated fluid temperatures. It can operate with cold and hot water, provided that the medium is free of fibres and solid particles and that the hot water is soft, with a low content of dissolved calcium and magnesium compounds.
Construction and materials
The construction is based on durable materials ensuring long-term, 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 in domestic hot water (DHW) circulation systems. The motor housing is made of aluminum, allowing the unit to combine good heat dissipation with relatively low weight.
- Motor housing: aluminum.
- 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 media).
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 degree of tightness.
Motor and electrical parameters
The pump is equipped with a high-efficiency IE3 electric motor, resulting 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 designed for continuous use in typical water and heating systems.
- High-efficiency motor: IE3 efficiency class.
- 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 fibers, sand, and other solid particles, which is crucial for protecting the hydraulic components and seals. When operating with hot water, soft water is required, limiting the risk of limescale deposits and extending the service life of the pump and system.
- Medium: clean water, free of fibers 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 head), and for a temperature of 90°C – 0.7 bar (7 m water head). The inlet pressure and installation height relative to the water level must always be verified during the system design stage, taking into account pressure losses and the characteristics of the supply source.
Installation and operation
The pump should be installed to ensure easy service access, 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 specific installation's requirements is recommended.
For long-term operation, periodic installation inspections, leak checks, and checks of the seals' condition 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 50-19-1.5 circulation pump
Which installations is the IGDL 50-19-1.5 pump best suited for?
The pump is recommended for water-supply installations, pressure boosting in tall buildings, HVAC and heating systems, including central-heating and domestic-hot-water circuits, as well as industrial circulation systems in which the medium is clean water.
Can the IGDL 50-19-1.5 pump operate with hot water, including in a domestic hot-water circulation system?
Yes. Thanks to its construction with 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 inlet pressure requirements on the suction side?
For a medium 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 50-19-1.5 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 operating manual's recommendations. In hot-water installations, it is advisable to monitor the water hardness and the condition of the seals.
