Peterson Oil Pump, R4, Dry Sump, 4 Stage
The Peterson R4 dry sump pump delivers a four-stage pressure and scavenge configuration in a compact, aluminum housing. Its low-profile design supports easier mounting in tight engine bays, with a 3/8 inch hex drive for straightforward installation. The aluminum construction enhances weight savings while providing adequate strength for demanding applications. This model focuses on a balanced pressure and scavenge balance to maintain stable oil pressure at higher RPM ranges.
Peterson Oil Pump, R4, Dry Sump, 4 Stage (Driver Side)
This driver-side version of the Peterson R4 4-stage dry sump pump keeps the same essential four-stage configuration with a compact footprint. The low-profile design facilitates mounting in constrained spaces, while the aluminum body preserves strength and heat dissipation. User-friendly hex drive ensures a reliable drive connection, making it a practical choice for performance installations requiring precise oil management.
Peterson Fluid Systems Oil Pump, Dry Sump, R4, 5 Stage
Although a five-stage option, this Peterson pump expands on the R4 family by providing additional scavenge capacity for higher-demand systems. Aluminum construction helps with weight reduction and heat management, while the manufacturer’s mounting interfaces support versatile installation. The packaging dimensions provide an idea of the unit’s footprint, which is useful when planning for space in custom setups where a larger scavenge capacity is beneficial.
Moroso 22344 4 Stage Tri Lobe Dry Sump Pump
The Moroso 22344 features a four-stage tri-lobe dry sump design with independent timing gears for the scavenging sections to maintain clearance at high RPM. The pressure section is a spur gear style aligned with Moroso’s billet wet-sump lineage. This setup supports stable oil pressure with higher RPMs and offers flexibility through variable spring rates to optimize performance and readability of oil pressure under varied conditions.
Moroso 22380 4 Stage Tri Lobe Dry Sump Pump
Moroso’s 22380 combines a 4-stage tri-lobe scavenging system with a 1.500 inch high-pressure spur gear section, designed for reliable oil delivery at high RPM and heavy loads. It includes multiple spring rates and an external bypass for ease of adjustment, enabling precise tuning for different engine builds and running conditions. The V-Band mounting capability offers robust, secure attachment in performance applications.
Miumoon 1500W Primary Sump Pump Backup System
While not a four-stage dry sump pump per se, this backup sump system from Miumoon integrates with primary sump operations to protect basements against flooding and power outages. It provides up to 1500 watts of output, automatic battery switching, built-in charging, and protection features. This unit complements a dry sump setup by ensuring oil and water management remain uninterrupted during electrical outages and extreme weather events. It is suitable for basement protection and handles switching between power sources automatically.
Buying Guide
Key purchase considerations for 4-stage dry sump pumps include stage balance, mounting compatibility, and material quality. A compact, low-profile design helps when space is limited in performance vehicles. Aluminum construction is common for lightweight strength and heat dissipation. Ensure the drive interface (such as 3/8 inch hex drive) matches your drive system. Tri-lobe scavenging arrangements can offer improved scavenging efficiency at high RPM, but may require more precise timing and maintenance. Consider whether you need a driver-side or passenger-side mounting option to fit your engine bay layout. Finally, verify available mounting options (bellhousing vs. V-Band) and any included bypass or spring tuning features that influence oil pressure stability across RPM ranges.
Performance-focused buyers should assess system compatibility with your engine architecture, including space for belhousing and hanger brackets, as well as alignment with your existing oil path hardware. For newer builds, opt for lightweight alloys to minimize rotational inertia while maintaining durability. When selecting a dry sump pump, evaluate accessory availability, such as fittings, adapters, and bypass components, to reduce installation complexity and the risk of leak paths. For backup scenarios, consider complementary systems like battery backup options to maintain continuous operation during outages.
