The HBT90.18.186RSU is engineered for flexibility, providing maximum theoretical conveying capacities of 93 m³/h in low-pressure mode and 54 m³/h in high-pressure mode. This adaptability allows operators to select the optimal setting for different job requirements, with corresponding concrete delivery pressures of 10 MPa (low pressure) and 18 MPa (high pressure).

The unit ensures fast and efficient concrete delivery with pumping times of 27.3 min⁻¹ in low-pressure mode and 15.8 min⁻¹ in high-pressure mode. Its pumping mechanism is built around concrete cylinders with a bore and travel.

Powering the pump is a BF6M1013--25T3R/1 diesel engine with a rated power of 186 kW at a rated engine speed of 2100 r/min. This engine adheres to the "Non-road country three" emission standards, ensuring reliable performance while meeting specific regulatory requirements.
