CPPHeavy Duty, Single Stage

ANSI Chemical Process Pump

For more than 60 years the name Ruhrpumpen has been synonymous worldwidewith innovation and reliability for pumping technology

Ruhrpumpen is an innovative and efficient centrifugal pump company that offers operators of Pump Systems a wide range of quality products. Ruhrpumpen is committed to worldwide excellence, with a complete range of pumps to support core markets such as Petrochemical, Oil & Gas, Power, Heavy Industry Applications, Mining and Water. Our broad product line complies with the most demanding quality standards and industry specifications such as: API, ANSI and Hydraulic Institute Standards.

The CPP-21 line is designed to meet or exceed ANSI B 73.1 specifications. All CPP-21 pumps are designed around a single, basic hydraulic and mechanical design concept which ensures efficiencies across a wide spectrum of operating conditions, unparallel application flexibility and superior interchangeability.

This rugged process pump is designed to operate dependably and even in the toughest industrial applications.

The CPP-21 line features 35 sizes to precisely meet service conditions within a wide range of hydraulic parameters including low flow high head parameters. The line was also designed to accommodate many different optional features such as wear rings on casing and impeller or water jackets for stuffing boxes and bearing housings.

Ruhrpumpen is proud to introduce it’s newest CPP-L Low Flow, High Head pump model. It’s radial vane impellers are specially designed to reduce the thrust load and seal chamber pressure normally associated with low flow application and it also complies with the ANSI B 73.1 Standard.

Ruhrpumpen’s quality program and in-house foundry, along with the latest testing equipment, ensures that the pumps we manufacture will provide long operating life, even under the most severe conditions.

C-FRAME

C-Frame assures proper alignmentand better seal life.

ANSI Chemical Process Pump

Introducing our new CPP-L, Low Flow, High Head Models

CPP-L DESCRIPTION

DESIGN FEATURES

- The CPP-L is the low flow option of the CPP-21 product line.

- Designed to fill the gap on the low flow side of the CPP-21 range map.

- Complies with the ANSI B 73.1 Standard, this pump can be used to replace existing equipment without any problem. There will be no need for piping or base changes.

- Ruhrpumpen’s CPP-L series is designed with a circular concentric casing together with a radial vane impeller to minimize shaft deflection and reduce excessive radial loads and thus prolonging bearing and seal life.

- CPP-L utilizes external impeller adjustment to restore pump efficiency and reduce downtime.

CPP-L

LOW FLOW, RADIAL VANE IMPELLER FOR THE CPP-L

- With low flow applications, it is important to reduce the radial load and potential shaft deflection issues. Ruhrpumpen’s radial vane impeller and concentric pump casing for the CPP-L are specifically designed to reduce these issues at low flow or throttled operating conditions. The radial vane impeller with balance holes also reduces seal chamber pressures. This will lead to increased seal and bearing life and less unplanned system downtime.
