CPI offers all the accessories necessary to get the most out of our divider blocks and to keep your compressor and lubrication system running at peak efficiency.

Lubrication - Divider Blocks for Methanol Applications

Methanol injection pumps are often used in wellhead and pipeline applications where seasonal drops in ambient air temperature result in the freezing of liquids falling out of the gas stream. By injecting methanol at various points, the potential for freezing is reduced or eliminated.

Lubrication - HP+ Divider Blocks

Divider blocks (also known as distribution blocks or divider valves) provided by CPI, part of the Howden group precisely distribute correct lubrication, reducing the size of lubricator boxes and maximizing lubrication system efficiency.

Lubrication - HVLP (High Volume Lubricator Pump)

The HVLP (High Volume Lubricator Pump) is designed to deliver precise quantities of lubrication oil to engines, compressors and other industrial applications.

Lubrication - Lube Guard Pump Assembly

The lube guard pump assembly provides protection for the lubrication system by verifying that the camshaft is rotating while also indicating a low oil level condition in the lubrication box.

Lubrication Product Guide

CPI provides industry leading lubrication system products and services, partnering with our customers to develop individual solutions to their unique lubrication needs.

Materials for Pump Wear Parts

CPI materials for pump wear parts are proprietary polymer alloys designed for pump bushing wear rings, guide bushings and thrust washers in liquid pumps.

Metallic and Non-Metallic Wear Products

To meet the needs of today’s compressor operations, we offer our packing and wiper rings and piston and rider rings in both metallic and non-metallic materials and in an array of designs to handle both common and more problematic applications.

Oil Wiper Rings

To provide positive control of lubrication, oil wiper rings are essential in preventing oils from causing contamination of gases and leading to failure of other critical parts within a compressor.

Packing Cases

The packing case is critical to the efficient operation of the piston rod packing and the sealing of the cylinder.

Poppet Valves

Best suited for low differential pressures and slower speed compressors, poppet valves are high lift valves with low pressure drop across the sealing elements.

Shutdown Devices - PROFLO® PF1 & PF1 24V

The Proflo® PF1 monitoring device provides shutdown protection for your compressor and collects operation data by monitoring the cycle times of the divider block system.

Solutions for common high-speed compressor issues

High-speed midstream natural gas compressors work harder and faster than most, accelerating valve and component wear. The CPI, part of the Howden group, Philadelphia Service Center has been solving problems with these compressors for years and specializes in solutions that extend the life of your components and compressor.

Valve Reconditioning and Replacement Parts

184 Material Ring Success

BOG (Boil-Off Gas) Natural Gas is a very demanding application on the sealing components of a reciprocating compressor due to the extremely low 1st stage suction temperatures, together with the very dry (low-dewpoint, bone-dry) gas condition. For this application CPI installed one of our well-known dry gas material grades CPI 184, which has proved to be very successful.

192 Material Pressure Breaker Eliminates Blow-by Issues

Customer was experiencing excessive packing blow-by and premature failure across all compressors using the B-1584-K packing set. The suggested solution by the OEM required a significant customer investment per compressor. CPI was asked to explore a possible solution in utilizing the OEM packing case B-3084. Operating Conditions: 250 PSI Inlet to 1200 PSI Discharge.

CPI - Ethylene Production

Eliminating Cooling from Packing Cases by Upgrading to CPI Polymer Alloy Packing Ring Materials.

Crude Nitrogen Compressor

Piston and rider runtime improvement in crude nitrogen compressor. Piston and rider ring lives have historically been known to be below 4000 hours.

Cylinder Valve Seat Repair

During service, a suction valve had become loose, causing significant damage to the suction valve, valve unloader assembly, valve chair and the cylinder valve seat surfaces.

EMISSIONGUARD™ TR²

The customer wanted to improve lifetime in this application’s particularly demanding conditions. The supercritical CO2 is a bio solvent, so within the compressor this acts as a cleaning agent, removing the transfer film from the piston rod surface, where it is essential to create the transfer film in dry running conditions, in order to achieve the optimum running life and sealing performance.

Hi-Flo™ Valves Increase Valve Life from 6 Weeks to 34 Months in midstream natural gas processing.

PUMPGUARD™ Refinery Case Study

Due to CPI’s long standing relationship with a major refinery in Spain built upon material successes with compressor solutions on site, this customer approached CPI to see if we could help to solve a recurring pump problem.

Unloaders & Actuators

CPI Unloader Diaphragm Actuators are used for replacing old style leaking or worn out unloader actuators, to remove membrane actuators in situations of membrane failure or insufficient stroke, or to replace manual hand-wheel style unloaders for automation.

Vertical Pump Problem Solving

Six years ago, the head of maintenance at a major refinery in France first tested CPI PUMPGUARD™ materials on their pump bearings on a barrel pump. The customer usually used an alternative leading non- metallic product but was finding the cost high.
