RDP Series reciprocating plunger pumps from Ruhrpumpen are used for high-pressure duties across industries where low leakage, high reliability and reduced running noise are paramount. They meet API 674 third edition and ISO13710. Available in triplex and quintuplex formats, they can handle pressures up to 14,500 psi at temperatures between minus 104 and 392 F. Leakage is reduced by using a high-quality seal arrangement with condition monitoring. Its stiffness reduces running noise and vibration, often eliminating the need for acoustic enclosures. It delivers a service life of 20 years while easily accessible service points reduce scheduled maintenance time. 918/627-8400; www.ruhrpumpen.com.
