CMMS Implementation for Positive Displacement Pumps

We design the asset hierarchy with equipment classification levels that distinguish PD pump types (reciprocating, rotary, metering, progressive cavity) and sub-types where maintenance requirements differ. Equipment records capture pump-specific attributes: pump type, displacement, speed, port size, elastomer material, process fluid, and operating conditions. BOMs are structured by pump type with the correct component breakdown — valve assemblies with seat and plate part numbers for reciprocating types, stator and rotor with elastomer grade for PC pumps, diaphragm assemblies with material specification for metering pumps. Failure coding uses ISO 14224 as the framework, extended with PD pump-specific failure modes: valve seat erosion, stator wear, diaphragm rupture, packing leakage, pulsation dampener failure. PM task libraries are built per pump type with appropriate task content and frequencies. Work order templates capture failure location (which valve, which stage), failure mode and mechanism, parts consumed, and next recommended action. KPI dashboards track reliability metrics by pump type, service, and elastomer material to support material selection optimization.
