Forte Water Pump Spring Seal FP20, FP30C (Kentavr, Sadko, Energomash)

Mechanical Seal (Oil Seal) for Water Pumps 20/21x45 mm (with Ø 35 mm Ceramic Stationary Ring)

Mechanical seal kit (mechanical seal with spring and ceramic stationary ring) is designed to seal the working chamber (volute) and protect the engine of gasoline and diesel water pumps with a capacity of 5.5 – 6.5 hp. It consists of a rotating spring-loaded part with a graphite/metal ring in a rubber sleeve and a stationary ceramic mating ring in a rubber seal.

Key Advantages and Features:

• High Tightness and Wear Resistance: The ceramic-graphite sealing pair ensures minimal friction and prevents pumped water from leaking into the engine housing.
• Spring Compensator: The built-in steel spring compensates for shaft runout and natural wear of the friction surfaces.
• Oil and Gasoline Resistant Rubber (NBR): Elastic elements do not degrade when in contact with mildly aggressive liquids, dirty water, and technical impurities.
• Complete Replacement Kit: Supplied as an assembly with the rotating unit and the stationary mating ring.

Compatibility with Water Pumps (for clean and slightly dirty water, 2" and 3" inches):

• Forte: FP20C, FP30C, FPTW30 (as well as 5.5–6.5 hp models);
• Kentavr: VBM2, KDM-50, LBM-80GKR;
• Sadko: WP-8030, WP 50;
• Yato, ODWERK: GP50 and analogues;
• Oleo-Mac: FS 45 TL;
• Energomash: BR-8760VD;
• Other brands: Brigadir, Champion, Viper, Hyundai, Kipor, Lifan, Rato, and most Chinese water pumps with Honda GX160 / GX200 (168F / 170F) type engines and a Ø 20 mm shaft.

Technical Specifications:

Package Includes:

1. Mechanical seal spring unit — 1 pc.
2. Ceramic stationary ring in rubber sleeve — 1 pc.

Installation Tip: When installing the mechanical seal, it is strictly forbidden to allow dirt, sand, or oil to get onto the mirror surfaces of the ceramic-graphite pair. Press the stationary ring into the housing without using impact tools, using a soap solution to facilitate the rubber seating.
