Next-Gen Architecture, Quiet Operation
Max Speed 3,500 rpm and 200 Bar
Leveraging our expertise in high pressure direct injection pump design and precision engineering, we crafted the SP1250-200 to set the technical standard for flexible packaging, lightweight design and quiet operation. Alongside high-volume output at 200 Bar and unsurpassed engine start times, the SP1250-200 delivers unprecedented performance with an efficient, fuel saving design.
QuietTech
Patented design features combined with hybrid materials and advanced coatings abate hydraulic and acoustic noise.
Numerous Engine Applications
Versatile features enable this pump to be used in twin-turbo V6 and V8 engines and naturally aspirated V8 engines.
Flexible Design
Highly-customizable features enable simplified integration with most engines and flex fuel compatibility.
Efficient Performance
Next-generation pumping architecture delivers excellent low-speed efficiency, class-leading start times and a low-mass design.
Unique Features
QuietTech™ Control Valve
- Ultra low noise design incorporates hybrid materials, dampened impact surfaces and sealing surface finishing techniques for superior noise reduction.
- Reduces reciprocating mass and impact surfaces with improved part count.
- Increases debris resistance.
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 Plunger Sleeve Mount and 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.
Low Mass Non-Metallic Outlet Valve
- Minimizes high-pressure pulsations with non-metallic discharge check valve.
- Pressure relief and discharge check valves enable simplified pump housing.
