Shurflo Marine Pumps and Fittings at Fisheries Supply
This brand page helps boaters select, configure, and maintain high-performance Shurflo marine pumps and water system fittings. Sourced directly through Fisheries Supply, these components ensure optimal engineering for reliable onboard fresh water delivery, deck washdown, waste maceration, and livewell circulation systems.
Shurflo: A Trusted Name in Marine Pumps
Shurflo is an established global manufacturer specializing in high-quality marine pumps engineered explicitly for the rigorous demands of fresh water, washdown, livewell, and waste management systems on boats. Fisheries Supply maintains a comprehensive, long-term inventory of Shurflo marine products, stocking a broad selection of specialized pumps and structural accessories configured for precise marine duty applications.
Core product lines features industry-standard models including Shurflo high-flow livewell pumps, the robust Shurflo Macerator series, and specialized Shurflo water filters. For pressurized plumbing demands, the well-known freshwater and washdown lines, such as the Aqua King and ProBlaster pump series, utilize marine-grade materials and components engineered to withstand demanding, corrosive environments aboard boats.
Key Technical Features of Shurflo Marine Pumps
Most Shurflo marine pumps are engineered for extended service lifecycles and straightforward mechanical installation across a wide range of hull profiles. The integrated engineering features detailed below ensure boat owners can maintain dependable water pressure and flow with minimal system maintenance.
- Multi-Position Mounting: Enables versatile pump orientation during installation to maximize space efficiency within tight marine lockers and utility compartments.
- Thermal Overload Protection: Built-in automatic safeguards designed to prevent electric motor damage or failure resulting from overheating conditions.
- Quiet 12V DC Operation: Engineered specifically for typical direct current (DC) boat electrical systems, offering reduced acoustic noise and minimized pump cycling profiles when paired with proper isolation mounts.
- Self-Priming Capability: Allows positive-displacement diaphragm pumps to efficiently lift water from vertical positions above the supply source, simplifying overall plumbing layout.
- Internal Bypass Mechanisms: Available on specific freshwater models to manage internal fluid flow and backpressure, delivering smoother operation and eliminating the absolute necessity of a bulky accumulator tank.
- 1 to 3-Year Limited Warranty: Reflects robust manufacturing construction standards, with specific warranty terms scaled according to the selected pump model class.
Types of Shurflo Pumps for Marine Applications
To support distinct fluid transfer operations across a boat, Shurflo designs and manufactures specialized pump categories optimized for targeted onboard systems:
| Pump Category | Primary Function | Key System Benefit |
|---|---|---|
| Freshwater Pumps | Supplies pressurized potable water to galleys, sinks, heads, and showers. | Consistent domestic fixture pressure mimicking residential delivery. |
| Waste & Macerator Pumps | Empties holding tanks and evacuates blackwater or greywater systems where permitted. | Dual-blade design grinds waste down for efficient high-volume transfer. |
| Washdown Pumps | Delivers high-pressure raw water streams onto decks and cockpits. | Efficient clearing of debris, mud, and organic material from gear and surfaces. |
| Livewell Pumps | Circulates continuous raw oxygenated water through bait tanks and livewells. | Maintains optimal environment to keep baitfish and catches healthy. |
Marine Pump Fittings, Drive Kits, and Maintenance Accessories
Securing a reliable marine plumbing layout requires compatible physical fittings, dedicated service kits, and operational accessories. Beyond our primary inventory of Shurflo marine water system pumps, Fisheries Supply stocks essential replacement spares and upkeep gear to ensure uninterrupted system uptime.
A critical preventive maintenance component for your freshwater or washdown systems is a genuine Shurflo valve and drive assembly kit. Because these primary lines utilize positive-displacement diaphragm designs rather than flexible rubber impellers, carrying a dedicated diaphragm repair kit or replacement check-valve assembly ensures you can rebuild the pump head in the event of particle damage or winterization splitting.
Essential Shurflo Accessories Include:
- Water Filters & Strainers: Essential protective screens installed on the intake side that trap suspended solids, sand, and marine debris before they can foul the pump's internal check valves.
- Vibration-Dampening Mounts: Heavy-duty mounting rubber feet designed to secure the pump body while dampening operational noise and structural vibration against the bulkhead.
- Inline Pressure Switches: Calibrated, ignition-protected electronic switches that sense line pressure drops to automate pump cycling for consistent flow delivery.
Frequently Asked Questions
What Shurflo pump do I need for a boat freshwater system?
A Shurflo freshwater pump is the right choice for pressurized potable water at boat sinks, galley faucets, heads, and showers. Match the pump voltage, gallons per minute, pressure rating, and port size to the existing marine plumbing system, then choose Aqua King II or another Shurflo water system pump that fits the demand.
Which Shurflo pump is best for washing down a boat deck?
A Shurflo washdown pump is best for cleaning mud, fish blood, salt, and debris from decks, cockpits, anchors, and gear. Look for Shurflo ProBlaster II or Blaster II models when the job requires higher pressure, raw water handling, and compatibility with hose nozzles, strainers, and marine pump fittings.
Can I use a Shurflo pump for a livewell or bait tank?
Yes, Shurflo livewell and bait pumps are designed to circulate raw water through bait tanks and livewells. Choose Shurflo Bait Sentry, ProBaitmaster II, or high-flow livewell pumps by voltage, gallons per hour, port size, and whether the system needs continuous circulation for baitfish or catch preservation.
What Shurflo parts help protect a marine water pump?
Shurflo strainers, water filters, check valves, pump fittings, and replacement diaphragm kits help protect marine water pumps from debris, pressure loss, and premature wear. A twist-on in-line strainer before the pump is especially useful because it traps sand, scale, and small particles before they reach internal check valves.
How do I choose the right Shurflo pump fitting size?
Choose Shurflo pump fittings by matching the pump port, hose inside diameter, and plumbing connection type. Common marine configurations include 1/2 inch ports, 3/4 inch fittings, straight adapters, swivel-nut adapters, hose barb connections, and quick-connect fittings for Shurflo Aqua King, ProBlaster, and Extreme Series pump installations.
What is a Shurflo macerator pump used for on a boat?
A Shurflo macerator pump is used to move waste from marine holding tanks where discharge is legally permitted and the plumbing system is configured correctly. The pump grinds blackwater or greywater solids into smaller particles, helping evacuate tank contents through compatible hose, fittings, valves, and marine waste-system components.
