Welcome to the Stenner Pump Company Injection Pumps category, your go-to source for premium replacement parts in the automotive fuel system lineup. Here, you'll find specialized peristaltic pumps and check valves designed for precise fuel injection, ensuring optimal performance and reliability in demanding applications. Whether you're maintaining a high-performance vehicle or tackling fuel system repairs, Stenner products stand out for their durability and accuracy, helping you avoid common issues like leaks or inconsistent flow.
Why Choose Stenner Pump Company for Injection Pumps?
Stenner Pump Company has built a stellar reputation over decades for engineering robust peristaltic pumps that excel in metering applications. What sets them apart is their use of roller-style peristaltic technology, which minimizes shear and pulsation while handling viscous fluids effectively, ideal for fuel injection systems in automotive settings. These pumps are constructed with corrosion-resistant materials, ensuring longevity even in harsh environments. Unlike generic alternatives, Stenner's designs prioritize precision, with adjustable flow rates and high-pressure capabilities up to 100 PSI, making them a trusted choice for professionals and DIY enthusiasts alike.
As part of the broader Fuel Injection category, Stenner pumps integrate seamlessly into comprehensive fuel system overhauls. Their self-priming nature and dry-running tolerance reduce maintenance needs, saving time and effort on repairs.
Key Features to Look for in Stenner Injection Pumps
When shopping in this category, focus on these standout attributes:
- Adjustable Flow Rates: Models range from 0.5 to 17 gallons per day (GPD), allowing customization for specific fuel delivery needs.
- Pressure Ratings: Consistent 100 PSI operation supports high-demand automotive applications without faltering.
- Peristaltic Design: Tube-based pumping prevents contamination, crucial for clean fuel injection.
- Check Valves: Essential accessories like the MCDBINJ and UCDBINJ models ensure one-way flow, preventing backpressure issues.
- Electrical Compatibility: 120-volt options for straightforward integration into standard automotive setups.
These features make Stenner pumps versatile for everything from daily drivers to specialty vehicles. If you're upgrading your entire setup, consider pairing with other components from our Fuel System selection.
Comparing Top Stenner Models in This Category
This category features five key products, blending check valves and peristaltic pumps to cover various needs. Let's break them down to help you decide:
The Injection Check Valve 1/4in. models (MCDBINJ and UCDBINJ) are compact essentials for maintaining directional flow in injection lines. The 5 MCDBINJ offers robust sealing for standard 1/4-inch lines, while the UCDBINJ provides similar reliability with slight variations in fitting compatibility. Ideal for quick replacements without overhauling the entire system.
For full pumping solutions, the 85MHP17 Peristaltic Pump shines with its higher capacity: adjustable from 0.8 to 17 GPD. It's perfect for applications requiring greater volume, like larger engines or continuous fuel metering.
The 45MJH2A1S and 45MJH2A4S models (both rated 0.5 to 10 GPD at 100 PSI, 120 volts) offer precision for moderate demands. The A1S variant emphasizes versatility in head adjustments, while the A4S (also known as 45MHP2) adds enhanced tubing life for prolonged use. Choose the 85MHP17 for max flow, or the 45-series for efficiency in smaller systems.
Comparing them head-to-head: If space is tight, go for check valves alone. For active pumping, the 45-series suits most automotive fuel injections due to balanced output, but scale up to 85MHP17 for high-performance builds. All models share Stenner's hallmark reliability, but match flow rates to your engine specs for best results.
Common Use Cases for Stenner Injection Pumps
