WFB-12P-CU Valveless Pump for Marine Diesel Additive Dosing

 

Reliable Additive Dosing for Marine Diesel Engines

Marine diesel engines require precise fuel additive dosing to maintain performance, protect injectors, and meet emissions standards. Combustion enhancers, lubricity improvers, and fuel stabilizers are commonly used to address the challenges of low-sulfur fuels and harsh operating conditions at sea.

The WFB-12P-CU valveless plunger pump is specifically designed for this application, delivering stable, consistent dosing of combustion enhancers into shipboard fuel systems.

Application Overview

Equipment: Diesel additive injector
Location: Onboard ships / marine engine rooms
Flow Rate: 60–600 ml/min
Connection: 1/4" BSP male
Medium: Diesel combustion enhancer / fuel additives
Quantity: 1 pump per system

Additive dosing systems on vessels typically meter combustion enhancers into the fuel line to improve ignition, clean injectors, and prevent deposits. While high precision is not the primary requirement, long-term stability and reliability are essential for uninterrupted marine operations.

Why the WFB-12P-CU Valveless Plunger Pump?

1. Stable, Clog-Free Operation
   Traditional pumps with mechanical valves are prone to wear and clogging when handling chemical additives. The valveless ceramic plunger design eliminates these failure points, ensuring consistent flow over extended periods. This stability, rather than ultra-high precision, is exactly what marine additive dosing demands.

2. Compact and Portable
   Marine additive injectors are often portable units moved between engine rooms or vessels. The WFB-12P-CU's compact footprint fits easily into small cabinets, making it ideal for applications where the dosing unit needs to be frequently carried around.

3. Cost-Effective
   Customers have eva luated multiple suppliers and confirmed that the WFB-12P-CU offers competitive pricing without compromising quality. It delivers the performance of more expensive systems at a fraction of the cost, ideal for fleet-wide adoption.

4. Corrosion Resistance
   The pump's wetted parts are constructed from high-quality materials including SiC ceramics and stainless steel, providing excellent chemical resistance for handling various fuel additives.
