Application:
The 2641720 diaphragm-type mechanical lift pump is purpose-built for Perkins T4.236 and AT4.236 turbocharged diesel engines (4.0 L, 4-cylinder) that drive Massey Ferguson 399, 550 and 650 agricultural tractors, MF 7200 combine harvesters, JCB 3CX backhoe loaders and 530-70 telehandlers, plus FG Wilson P22-6 and Pramac GSW85P skid-mounted generator sets. It mounts on the left-hand timing-gear cover and draws fuel from the tank to the high-pressure injection system across engine speeds from 750 r/min idle to 2 400 r/min rated.
Technical specifications:
Cast-iron body with integral hand-priming lever delivers 95 L/h at 300 kPa and 2 000 r/min; inlet and outlet ports are 8 mm hose-barb fittings. Four-bolt mounting pattern (58 mm × 58 mm PCD) is driven directly by the camshaft eccentric. Diaphragm diameter is 78 mm, stroke 5 mm, and the internal bypass valve limits pressure to 350 kPa. All sealing gaskets are FKM (Viton) for biodiesel compatibility up to B20 and arctic-grade diesel down to −40 °C.
Material & performance features:
Powder-coated cast-iron housing resists salt-spray and stone-chip corrosion; multi-layer fabric-reinforced nitrile diaphragm faced with PTFE ensures low swell and extended flex life. Induction-hardened medium-carbon steel lever and push-rod resist wear, while a stainless-steel return spring prevents sag in humid climates. A translucent sight-bowl sediment filter with 80 µm paper element traps water and debris, and the spring-loaded priming lever allows rapid manual bleeding after service. Lightweight, maintenance-free sealed bearings and quiet operation suit continuous-duty agricultural, construction and standby-power applications.
