RMI PRESSURE SYSTEMS

ADVANCE CONTROL SOLUTION

RMI believes that power without control creates waste. Their intelligent expert control systems provide configurable, and optimisation of system performance as operating conditions change. Cutting-edge technology such as ODIN (On Demand Intelligence) developed for mining, monitors the longwall hydraulic system and anticipates the required movement of the powered roof supports. Modulating the pump's speed in anticipation of system changes creates a significantly more responsive and economic system.

POSITIVE DISPLACEMENT PUMPS

RMI specialises in supplying positive displacement pump, which also known as a piston pump or reciprocating pump. The rotating motion of the motor is converted into a reciprocating motion that drives the pump pistons. The water flow delivered by this type of pump changes with the number of pistons (plungers), piston surface areas, pump stroke length and also the speed of the pump. The pump can also delivery near-constant feed flow rate with practically the same efficiency as pressure changes, i.e. a very flat pump curve.

​

RMI's pump can achieve 99.5% of volumetric efficiency at the rated pressure and speed and 96% of mechanical/hydraulic efficiency. This gives an impressive overall efficiency of over 95%.​ One of the core value of RMI is to save energy and eliminate waste. RMI systems use the latest control philosophy to suit the specific application and maximum the productive and uptime of the system. RMI system is known as very reliable, thanks to the advance control system, and often provide a system availability of 99%. RMI's engineering team has a vest of experience in adopting variable speed control technology to suit different applications. Parallel pumping is also a critical strength of RMI, meaning all pumps are running at the same speed in a multiple pump system, to suit actual demand. Such a control method is not only saving massive energy, by running the pump to adapt precisely to the demand flow, but the technology is also minimising the wear and tear of the system, which in turn maximising the reliability and productive, as well as reducing the overall product life ownership cost.
