Horizontal Split CaseFor more than 60 years the name RuhrpumpenTM has been synonymous worldwidewith innovation and reliability for pumping technologyRuhrpumpen is an innovative and efficient centrifugal pump technologycompany that offers a wide range of quality products to our clients.Ruhrpumpen is committed to global excellence with a complete range ofPumps, Fire Pump Packages and related products, such as DecokingSystems and Tools to support the core markets, namely Oil & Gas,Petrochemical, Power, Heavy Industry Applications, Mining and WaterServices.The broad product line complies with the most demanding qualityspecifications and goes beyond stringent industry standards such as API,ANSI, Hydraulic Institute, Underwriter’s Laboratories, Factory Mutual andISO 9001.Ruhrpumpen is a vertically integrated company with its own foundry,machine shop, pump manufacturing plants and service centers. Withstrategically located manufacturing plants, operating offices and servicecenters in many parts of the world, Ruhrpumpen is truly a global pumpcompany which also has the strength to focus on the local necessities ofeach client.CPOCPO ANSI Chemical Process PumpsThe CPO line is designed to meet or exceed ASME/ANSI B 73.1specifications. All CPO pumps are designed to provide superiorhydraulic performance superior reliability and low total cost ofownership.This rugged process pump is designed to operate dependablyand even in the toughest industrial applications.The CPO line features 31 hydraulics and an open impellerdesign that covers a wide range of service conditions (includinglow-flow region) while providing industry-leading low NPSHRperformance and high efficiencies.CPO is designed around a modular concept which allowsprovision of multiple hydraulics with a small number of powerframes. In addition these power frames are interchangeablewith models of other common pump manufacturers.CPO-L, Low Flow, High Head ModelRuhrpumpen offers its CPO-L Low Flow, High Head pump model. It’sradial vane impellers are specially designed to reduce the thrustload and seal chamber pressure normally associated with low flowapplication and it also complies with the ASME/ANSI B 73.1 Standard.The CPO-L is the low flow option of the CPO product line, designedto fill the gap on the low flow side of the CPO range map. With lowflow applications, it is important to reduce the radial load andpotential shaft deflection issues. Ruhrpumpen’s radial vane impellerand concentric pump casing for the CPO-L are specifically designedto reduce these issues at low flow or throttled operating conditions.The radial vane impeller with balance holes also reduces sealchamber pressures. This will lead to increased seal and bearing lifeand increased reliability.CPO-L2Tel: 866-777-6060Fax: 866-777-6383Springer Pumps, LLCwww.springerpumps.comInt'l: 001 267 404 2910
