High Output, Single-Pump Solution
Max Speed 3,500 prpm and 200 Bar
Stanadyne’s SP1550-200 offers the greatest flow output at 200 Bar of our high pressure direct injection pumps. Designed for unmatched reliability on high displacement engine applications, a single SP1550-200 out performs the dual-pump strategies of the competition, saving on space, weight and installation time.
Efficient Performance
Next-generation pumping architecture delivers excellent low-speed efficiency, class-leading start times and a low-mass design.
Numerous Engine Applications
Versatile features enable this pump to be used in engines up to 680 HP, twin-turbo V6 and V8 engines, high displacement V6 and V8 engines and naturally aspirated V8 engines.
Flexible Design
Highly-customizable features enable simplified integration with most engines and flex fuel compatibility.
Unique Features
Patented Dual-Spring Design
- Separates tappet and plunger spring loads to reduce spring induced plunger side loading.
- Promotes fluid film replenishment at plunger to bore interface.
- Increases robustness to poor quality fuels.
Patented Floating Sleeve Mount & Plunger
- Minimizes plunger to bore clearance for better engine start times and class-leading low speed efficiency.
- Eliminates plunger bore distortion due to mounting loads.
- Minimizes debris generation.
- Excellent seizure resistance.
Patent Pending Auxiliary Pressure Relief Valve
- Prevents over-pressurization of the fuel system.
- Fail safe feature for high volume, high pressure applications.
