WESPC 554/126 Front Crankshaft Oil Seal for Perkins 4000 Series Diesel Engine

WESPC 554/126 Front Crankshaft Oil Seal for Perkins 4000 Series Diesel Engine

Application:

WESPC 554/126 water pump is engineered for Perkins 4.236 and 4.248 diesel engines, which are widely used across agricultural tractors, construction machinery, generator sets, and industrial systems. This pump is mounted on the front of the engine block and driven by the crankshaft via belt or gear. It circulates coolant through the engine and radiator, maintaining optimal operating temperature and preventing overheating during continuous-duty and high-load operation.

Agricultural machinery:

Commonly installed in Massey Ferguson 200 and 300 series tractors, as well as other OEM platforms using Perkins 4.236 engines. The WESPC 554/126 water pump ensures consistent coolant flow during field operations, protecting engine components from thermal stress and supporting long service intervals.

Construction equipment:

Suitable for compact loaders, telehandlers, and site dumpers powered by Perkins 4.236 engines. The pump withstands vibration and dust exposure, maintaining coolant circulation in rugged environments and ensuring reliable engine performance during excavation, lifting, and transport tasks.

Generator sets:

Applied in 30–80 kVA diesel generator platforms powered by Perkins 4.236 engines, including units from FG Wilson, Olympian, and other industrial genset manufacturers. The WESPC 554/126 water pump supports efficient heat dissipation during prolonged operation, reducing the risk of thermal shutdown and ensuring stable power delivery.

Industrial systems:

Used in stationary diesel-driven systems such as irrigation pumps, compressors, and mechanical drives requiring robust cooling performance. The pump’s impeller and housing design optimize coolant flow rate and pressure, supporting 24/7 operation in high-temperature environments.

Technical specifications:

Pump type: centrifugal water pump Mounting: front engine block, belt or gear driven Inlet diameter: approx. 35.00 mm Outlet diameter: approx. 30.00 mm Impeller material: cast iron or reinforced composite Housing: precision-machined cast iron Seal type: mechanical seal with high-temperature elastomer Flow rate: approx. 100–130 L/min (varies by engine speed) Operating temperature: -30°C to +120°C Inspection: pressure-tested for leakage, flow rate, and dimensional accuracy

Material & performance features:

Manufactured using corrosion-resistant cast iron with reinforced impeller blades for high-volume coolant circulation. The mechanical seal is designed to prevent coolant leakage under variable pressure and temperature conditions. Engineered for long-term durability in agricultural, construction, and industrial environments. Produced under ISO/TS16949-certified quality control standards.

Interchange part number:

554/126; verified fitment for Perkins 4.236 and 4.248 series engines. Compatible with standard rebuild procedures across tractors, loaders, generator sets, and industrial systems.
