WESPC Primming Pump 130506300 For Engine 403D-07 402D-05 404D-22

Application:

The 130506300 priming pump is a hand-actuated lift pump that sits directly on the fuel filter head of Perkins 400 Series engines, specifically the 402D-05, 403D-07, 403D-11 and 403D-15 models used in compact tractors such as the Massey Ferguson 1726E and 1734E, mini-excavators, skid-steer loaders, mobile lighting towers, welders and 20–60 kVA generator sets. It is also found on earlier 4.236 and 4.248 family engines when those engines have been updated with the 400 Series filter housing, so its service range spans agricultural, construction, materials-handling and stationary power markets from the late 1990s to the present day.

Technical specifications:

The pump body is a one-piece aluminium die-casting, overall length 63 mm, barrel diameter 28 mm, with a moulded acetal resin plunger. A single Viton O-ring and fluoropolymer back-up ring on the plunger rod provide leak-free operation at fuel temperatures up to 100 °C and suction pressures down to –0.6 bar. The unit delivers 0.8 cm³ of fuel per full stroke, generating 1.2 bar discharge pressure with three to four strokes after filter change, thereby filling the filter canister and low-pressure gallery in less than 15 seconds. The pump is M14 × 1.5 threaded into the filter head and sealed by a captive copper crush washer; weight 65 g.

Material & performance features:

The aluminium casting is hard-anodised to MIL-A-8625 Type II for corrosion resistance in high-humidity environments, while the plunger rod is stainless steel for zero galling and long-term chemical compatibility with ultra-low-sulphur diesel and biodiesel blends up to B20. Internal check valves are moulded from ethanol-resistant fluorocarbon elastomer, giving rapid re-prime after filter service and eliminating the need for external bleeding screws. All sealing elastomers are certified to SAE J30R9 for fuel immersion, ensuring reliable cold-start capability down to –30 °C.
