1. Product Overview
We supply full range of brand new original EVAC marine vacuum sewage system spare parts, covering hot-selling part numbers: EVAC 6543035, EVAC 5327004, EVAC 6545510, EVAC 6540931, EVAC 5437587, EVAC 5957600, EVAC 6551993, EVAC 6541213, EVAC 6580439, EVAC 5442201.
As a world-leading brand in marine vacuum wastewater treatment solutions, EVAC equipment is widely installed on various ocean-going vessels, offshore platforms, cruise ships and luxury yachts to realize centralized collection, vacuum transportation and standardized harmless treatment of domestic sewage on board, complying with IMO international marine environmental protection emission regulations.
All spare parts are manufactured in EVAC Finland factory, strictly following international marine industry production specifications. Each component has passed salt spray corrosion test, air tightness test, cyclic pressure aging test and marine vibration reliability test. Adopting marine-grade stainless steel, brass and high-strength anti-corrosion engineering plastic materials, these replacement parts can resist long-term erosion of seawater, salt fog, oil mist and humid cabin environment, effectively avoid equipment vacuum leakage, sewage pipeline blockage, valve sealing failure and other common on-board faults.
Once the vacuum sewage system fails to operate normally, the ship will face the risk of being detained and fined by port environmental supervision departments, so using original EVAC genuine spare parts is the core guarantee for safe navigation and compliant operation of vessels.
These series spare parts are core wearing and vulnerable components of EVAC vacuum sewage collection system, including vacuum control valves, sealing assemblies, pipeline connectors, sewage detection sensors, pressure regulating components and other key accessories. They realize stable negative pressure collection of domestic wastewater from cabins, galleys and washrooms, and transport sewage to the on-board sewage treatment device through closed vacuum pipelines, helping shipping companies meet international MARPOL environmental protection emission standards.
We keep all above listed model numbers in sufficient stock, support small-batch trial orders, ship emergency spare parts replenishment and large-scale shipbuilding project centralized procurement, and provide one-stop marine spare parts technical matching, after-sales maintenance guidance and 12-month global warranty service.

5. Key Product Advantages
5.1 100% Original Genuine & Strict Marine Grade Inspection
All spare parts are imported from EVAC Finland factory, each product is equipped with unique traceable serial number and factory inspection report, no refurbished or counterfeit products. Every batch passes salt spray, high-low temperature alternating aging and cyclic sealing tests to adapt to high humidity, high salt fog and frequent vibration cabin environment.
5.2 Original Standard Size, Direct Replacement to Reduce Ship Downtime
Ultra-low dimensional tolerance ensures plug-and-play installation without cutting, punching or pipeline transformation. It greatly shortens berthing maintenance cycle, avoids shipping schedule delay and economic loss, and quickly restores the rated operating efficiency of sewage vacuum system.
5.3 Excellent Anti-Corrosion & Sealing Performance, Avoid Port Penalty
Marine anti-salt-fog raw material plus multi-channel sealing design effectively solves vacuum air leakage, sewage backflow, pipeline blockage and other common faults. Original spare parts ensure the vessel complies with MARPOL international environmental protection regulations to avoid detention and heavy fines.
5.4 Global Valid Marine Certifications for Smooth Customs Clearance
All products are approved by CE, RoHS, DNV, GL classification society certifications, meeting equipment access standards of all global ports. We can provide complete set of customs documents including commercial invoice, packing list and certification copies.
