GP BASIC BO + OHI C.O. 25-60/130 – IBO direct-circuit pump group
GP BASIC BO is a pump group by IBO with a direct circuit, supplied with an energy-efficient OHI C.O. 25-60/130 circulation pump. It distributes the heating medium between the heat source and receiver without changing its temperature, while integrated thermal insulation reduces heat loss from the system.
Who it’s for
- Boiler room and heating system installers – the factory-assembled group, complete with insulation, thermometers, and union fittings, shortens heating circuit installation time.
- Systems that do not require a change in the medium’s temperature – the direct circuit transfers the medium at the source temperature straight to the receiver.
- Heat buffer charging systems – high flow capacity (Kvs 10 m³/h) supports high-flow circuits.
- Technical service – integrated thermometers and shut-off valves allow the circuit to be isolated and inspected without draining the system.
Applications
- Charging domestic hot water tanks.
- Charging heat buffers.
- Radiator systems.
- Underfloor heating systems.
- Circuits in which the medium is transferred without changing its temperature.
The GP BASIC BO pump group with an OHI C.O. 25-60/130 pump (230 V) is mounted on a wall or manifold, on the heating-medium side.
GP BASIC BO group features – description and technical data
The group body is made of steel and brass, and the entire unit is covered with front and rear thermal insulation made of expanded polypropylene, which reduces heat loss from the circuit. The group has two analog thermometers integrated with the shut-off valves, enabling simultaneous temperature readings on the supply and return lines and flow shut-off without draining the system. W the return shut-off valve is a check valve that prevents uncontrolled reverse flow, and the union fittings make installation easier.
The GP BASIC BO direct circuit transfers the medium at the source temperature to the receiver without mixing. The group is supplied with an energy-efficient OHI C.O. 25-60/130 circulation pump featuring a permanent-magnet motor (efficiency class EEI ≤ 0.23), AUTO/ECO mode, and three fixed-speed settings. The group’s flow coefficient is Kvs 10 m³/h.

Frequently asked questions (FAQ) – GP BASIC BO pump group
What is the GP BASIC BO pump group used for?
The IBO GP BASIC BO distributes heating fluid through the system circuit, operating with the included OHI C.O. 25-60/130 circulation pump. It is used for loading domestic hot water tanks and thermal storage tanks, as well as in radiator and underfloor heating systems.
Which GP BASIC version should I choose – BO, 3D-S, or 3D-T?
The choice depends on the application and how the temperature is controlled. GP BASIC BO (direct circuit) transfers the fluid at the source temperature without changing it and is used for loading domestic hot water tanks and thermal storage tanks, as well as in radiator and underfloor heating systems. GP BASIC 3D-S (three-way valve with an IBO STER-D actuator) is designed for radiator and underfloor heating systems with automatic temperature control via a signal from an external controller. GP BASIC 3D-T (thermostatic valve) is designed for radiator and underfloor heating systems with manual temperature adjustment in the 25–55°C range.
Does the GP BASIC BO group change the fluid temperature?
No – the GP BASIC BO operates in a direct circuit and transfers the fluid at the source temperature directly to the consumer. The GP BASIC 3D-S and GP BASIC 3D-T versions are designed to change (mix) the temperature.
What pump is included with the GP BASIC group?
The unit is supplied with an energy-efficient OHI C.O. 25-60/130 circulation pump (130 mm port spacing), featuring a permanent magnet motor with an efficiency class of EEI ≤ 0.23 and a 230 V power supply.
How do I install the GP BASIC pump group?
Install the unit on a wall or manifold in a dry, frost-protected location. The upper connection has a G1" female thread. Before starting up the system, fill it with the operating fluid and bleed it.
Where can I buy the GP BASIC BO pump group?
The manufacturer does not sell directly. The GP BASIC BO pump group is available from retail partners, plumbing wholesalers, and authorized online distributors.
What warranty does the GP BASIC BO pump group have?
The IBO GP BASIC BO pump group comes with a 24-month (2-year) manufacturer's warranty. Warranty and post-warranty service is provided by Dambat.
