Ship WP200 Air Compressor Complete Overhaul Spare Kit

WP200 & H264 Air Compressor Overhaul & Valve Repair Kit is a critical full-set maintenance component for marine air compressors. Assembled with high-quality valve plates, valve springs, sealing gaskets and core wearing parts, it restores standard valve sealing and stable gas intake and discharge. It features precise dimensional accuracy, excellent pressure resistance and long-lasting sealing performance, suitable for routine servicing, shipyard overhaul and fault repair under marine high-pressure cyclic working conditions.

A well-matched complete overhaul kit stabilizes compressor air output, prevents air leakage and pressure loss, reduces component failure risks and equipment downtime, and ensures efficient and reliable operation of marine WP200 and H264 air compressors. Please provide compressor model, specifications and part number before ordering to confirm compatibility.

Overhaul Performance Recovery for Marine WP200 Two‑Stage Water‑Cooled Piston Air Compressor

WP200 complete overhaul spare kit is the full‑range maintenance consumable package for SAUER WP200 marine two‑stage water‑cooled starting‑air compressor. The kit integrates suction & discharge valve assemblies, valve plates, valve springs, piston rings, full‑set gaskets, O‑rings and other core wearing components. Under long‑term harsh marine operating conditions, frequent high‑pressure reciprocating movement will trigger valve plate fatigue cracking, spring relaxation, piston ring wear, gasket aging and sealing surface abrasion. These defects cause compressed‑air backflow, reduced air displacement and slow pressure build‑up. Full replacement with this overhaul kit restores original assembly clearance, rated air output and stable pressure capacity of WP200 compressor unit.

Role in Vessel Compressed‑Air System Operation

Complete wearing components inside the overhaul kit guarantee accurate opening‑closing timing for first‑stage and second‑stage compression chambers. Reliable one‑way sealing eliminates internal and external air leakage inside the compressor. Well‑matched spare parts maintain continuous and qualified compressed‑air supply, delivering stable air source for main engine starting‑air system, pneumatic control circuits and other onboard auxiliary equipment during long‑distance open‑sea navigation and port berthing.

Materials for WP200 Air Compressor Complete Overhaul Spare Kit Components

High‑Fatigue Spring Steel, Wear‑Resistant Alloy & Composite Non‑Asbestos Sealing Material

Valve plates adopt heat‑treated high‑fatigue spring steel, resisting repeated bending impact under high‑frequency reciprocating cycles. Valve springs are made of anti‑corrosion spring steel to cope with onboard salt‑fog and humid atmospheric environment. Piston rings adopt wear‑resistant alloy material to reduce cylinder wall friction loss. Gaskets and O‑ring sealing elements adopt high‑temperature resistant non‑asbestos composite material, maintaining stable sealing performance under compressor working pressure and temperature. All spare parts follow SAUER WP200 OEM material standards.

Machining Tolerances and Surface Finish

Every component of WP200 overhaul kit is processed strictly in accordance with SAUER WP200 OEM drawing specifications. Valve plates go through precision cutting, heat treatment and surface lapping for flat sealing contact with valve seats. Piston rings keep precise opening clearance and outer‑diameter tolerance. Critical dimensions including spring free length, gasket thickness and sealing groove size are fully inspected. Fine‑finished mating surfaces eliminate fitting gaps and lower air‑leakage risks.

Applications for WP200 Air Compressor Complete Overhaul Spare Kit Replacements

Main Engine Starting‑Air Compressor Overhaul

Valve‑group assemblies, piston rings and sealing gaskets are key wearing parts for periodic overhaul of SAUER WP200 starting‑air compressor. Long‑term impact load may cause valve plate fracture, spring fatigue failure and piston‑ring abrasion, resulting in air back‑flow, insufficient air displacement and slow pressure rise. Installing the complete WP200 overhaul kit restores compressor suction‑exhaust performance to original design parameters.

Auxiliary Engine Air Compressor Maintenance

WP200 units serving for auxiliary engine air supply also need regular overhaul kit replacement. Especially for vessels sailing in coastal high‑salt‑fog zones or dusty port operating conditions, timely replacement of full set of consumables ensures stable compressed‑air supply for main and auxiliary engines during port berthing and open‑sea navigation.
