HOUSTON, May 3, 2010 – Parker, the global leader in motion and control technologies, will display the latest addition to Amstrong RMI’s S range of plunger pumps – the S500 – at the Offshore Technology Conference.
The 60 Hz S500 features a five-plunger design that offers several advantages over the traditional three-plunger configuration, including lower forces on the crankshaft and associated bearings and a 40-percent reduction in per-plunger fluid velocity. These benefits contribute to greater pump reliability and reduced downtime.
The robust, five-plunger design, which also produces lower hydraulic noise and pressure pulses, reduces the impact of surges on other critical equipment within the system, increasing life expectancy. The pump also features ceramic ramps with a lead bronze big end and small end bearing, as well as stainless steel stuffing boxes.
Variable speed drive options can be matched to pump-motor and application requirements, offering improved efficiency over constant speed systems by matching system volume requirements in real time. Pumps run slower during low-flow system demands and ramp up to full volume when needed, resulting in longer product life and less noise.
Motor power runs between 400 and 547 HP, while pump flow ranges between 123 and 315 GPM with pressure ranges between 2821 and 722 PSI.
