About the programme
ROS-RYB pumps are designed, machined, assembled and tested as one programme: the same team that sets the duty envelope runs the endurance bench.
The range grew out of one problem — small turbine engines stalling when air reaches the fuel line. The three-gear head was the answer, and it now carries across twelve models from a 120 g 3S pump to a 28 V unit holding 1.0 MPa to 12 000 m.
Every model is released against a written technical-status sheet: mass, voltage, current, outlet pressure, flow, duty cycle, temperature and altitude limits, fuel specification and leak criteria. Those are the numbers on this site, and they are the numbers we are held to.
No certification claims are made on this site. If your programme requires a specific standard, tell us and we will confirm what can be supplied.
