Collection: Heavy Duty Truck

We supply hydraulic pumps and engine components for heavy-duty trucks, commercial vehicles, and on-highway applications. Whether you operate a fleet of dump trucks, tanker trucks, flatbed carriers, or specialized heavy vehicles, HE PUMP has the replacement parts you need to minimize downtime and keep your trucks running. Our products cover the full range of heavy truck hydraulic and engine systems — from PTO-mounted hydraulic pumps for dump bodies and truck-mounted cranes, to engine water pumps, oil pumps, and fuel transfer pumps for diesel engines. Every part is manufactured to OEM-compatible specifications for drop-in fitment, with 12-month warranty coverage on all products.

Heavy Duty Truck Hydraulic Applications

Hydraulic systems are critical to heavy-duty truck operation. We supply pumps for all major hydraulic applications:

• Hydraulic PTO Systems: Pumps for dump truck lift cylinders, tanker loading/unloading arms, and truck-mounted cranes — PTO-mounted gear pumps delivering high flow for demanding work cycles
• Power Steering: Hydraulic gear pumps for heavy vehicle steering systems — loss of steering pump function makes heavy trucks unsafe or impossible to drive
• Brake Systems: Hydraulic pumps for air-over-hydraulic brake systems on medium-duty and heavy-duty trucks requiring hydraulic pressure assist
• Wet Kit / Hydraulic Circuits: Pumps and components for wet line kits used by trailer-mounted hydraulic equipment
• Lift Gates & Tail Gates: Hydraulic pumps for delivery truck lift gate systems

Truck Engine Compatibility

Our heavy-duty truck pump inventory covers the most common on-highway diesel engines:

• Caterpillar: C11, C13, C15, C18 (on-highway truck engines) — classic CAT truck engines known for durability and torque
• Cummins: ISX15, ISX12, ISM, QSM, QSX series — the most widely used heavy truck diesel engines in North America
• Volvo/Mack: D11, D13, D16, MP7, MP8, MP10 series — modern heavy truck engines with integrated emissions control
• Scania: DC09, DC13, DC16 series — European heavy-duty truck and bus engines
• Mercedes-Benz: OM471, OM473, OM501 series — Mercedes heavy truck and commercial vehicle diesel engines

Engine Component Applications

Heavy-duty truck diesel engines demand reliable lubrication, cooling, and fuel delivery. We supply:

• Engine Water Pumps: Coolant circulation pumps for heavy truck diesel engines — overheating destroys expensive engine components rapidly
• Engine Oil Pumps (Lube Pumps): Lubrication system pumps for heavy truck diesel engines — low oil pressure at highway speeds can cause catastrophic engine failure
• Fuel Transfer Pumps (Lift Pumps): Fuel delivery pumps for heavy truck diesel engines — ensures consistent fuel supply to high-pressure injection system

Signs of Pump Failure in Heavy Trucks

Heavy-duty truck pump problems create safety risks and costly roadside breakdowns. Watch for these warning signs:

• Dump body won't lift: PTO pump has failed — truck cannot unload cargo, creating delivery delays
• Hard steering: Steering pump failing — heavy trucks become unsafe to drive
• Engine overheating: Water pump failure — highway operation with failed water pump can destroy an engine in minutes
• Low oil pressure at highway speed: Oil pump worn — catastrophic engine failure imminent if not addressed immediately
• Loss of engine power: Fuel transfer pump failing — engine starves for fuel under load
