Automatic demand diaphragm pumps that start when a faucet opens and stop once pressure builds again. Flow runs from 2.3 GPM on the compact Revolution 4028-100-E54 to 5.3 GPM on the 5059-1310-D011, so the number of fixtures running at once decides the size. Unlike the task pumps next door, these models are plumbed permanently into RV, boat and utility water systems, and the group also includes 2088 series pumps with a 115VAC version for use near an outlet.

What sets SHURFLO diaphragm pumps apart
PSI automatic switching on demand
Most pumps in the range are automatic demand designs: a built-in pressure switch starts the motor when a tap opens and stops it when pressure recovers. The Revolution 4028-100-E54 shuts off at 50 PSI and restarts at 40 PSI, the SLV10-AA40 turns on at 25 PSI and off at 40 PSI, and the 8000-543-238 cycles between 85 and 100 PSI.
Self-priming capability measured in vertical feet
Self priming diaphragm chambers lift liquid to the pump without pre-filling the line. Lift differs by model: up to 12 vertical feet on the 2088-343-135, 10 vertical feet on the 8000-543-238, 8 feet on the 8000-543-936 and 5059-1310-D011, and 6 feet on the 4048-153-E75 and Aqua King II.
Chemical resistant valves and diaphragms
Sprayer models pair Viton valves with a Santoprene diaphragm, the combination used on the 8000 series, the 2088-343-135 and the 5059-1310-D011. The SLV10-AA40 goes further with no metals in the fluid path, which matters when the liquid should not touch metal parts.
Bypass and run dry protection
An internal or mechanical bypass reduces cycling at low flow on the Revolution 4008-101-E65, the 4028-100-E54 and the Aqua King II, which has an adjustable one. Several pumps also run dry without damage, including the 8000-543-936 and the 4048-153-E75, so an empty tank does not damage the pump.
What the pumps and fittings are made of
Wet parts follow the job. Fresh water pumps such as the 4048-153-E75 get durable construction from a Santoprene diaphragm, EPDM seals, a polypropylene housing and stainless steel hardware, while sprayer pumps swap in Viton valves for chemical resistance. The oil change and winterizing pump uses a nylon housing and a Geolast diaphragm for oils, transmission fluid and antifreeze.
Fittings come in two plastics: the 244 series wingnut swivels are nylon, and the 234-3946 elbow has a polypropylene barb. Strainers such as the 255-323, 255-313 and 255-213 carry a 50-mesh stainless steel screen and come apart for cleaning, so rinse the screen whenever the bowl shows debris.
Two limits are worth writing down. The Aqua King II handles water up to 130°F, and the 155002-43 carbon paper cartridge filters up to 2,500 gallons before it needs replacing.

Match the pump to your flow before you order
GPM, PSI, voltage and port sizes for every SHURFLO pump, strainer, fitting and repair kit in one catalogue.
Compare the rangeWho needs which pump, and when
A motorhome running shower and kitchen together
A shower and a kitchen tap open at the same time call for more flow. The 4048-153-E75 moves 4.0 GPM at 55 PSI through a four-chamber diaphragm, self-primes up to 6 feet and ships with a 50 mesh strainer and two hose barbs for installation.
Rinsing salt off the deck after a day offshore
Anchors and decks come back coated in salt and grime. The Blaster II, a marine diaphragm pump 12V boat systems can power, delivers 3.5 GPM at 45 PSI, works with fresh or salt water and has run dry protection for when the intake loses water.
Spraying a field or lawn from a 12V battery
Spot spraying on a farm or lawn rig usually runs off a vehicle battery. The 8000-543-936 gives 1.8 GPM at 60 PSI, primes up to 8 vertical feet and has an integrated check valve. If your sprayer needs more pressure, the 8000-543-238 reaches 100 PSI.
Winterizing a camper and changing the oil
End-of-season jobs mean moving antifreeze, engine oil or transmission fluid. The 8050-305-426 clips to a battery with 8 ft leads and alligator clips, pumps up to 1.55 GPM and has thermal overload protection with automatic restart. Thick, high viscosity gear oils are outside its range.
About this pump and parts guide
This site is an independent catalogue of 12V water pumps and the parts around them. It covers four groups: RV fresh water pumps from the 2.3 GPM Revolution 4028-100-E54 to the 5.3 GPM 5059-1310-D011, marine and sprayer pumps, strainers and fittings, and repair kits.
The pumps share a demand diaphragm layout, but they split clearly by use. Fresh water models keep consistent water pressure at taps and showers; washdown, livewell and 8000 series sprayer pumps are built around a single task; the SLV10-AA40 and the oil change pump cover low-volume transfer.
The parts side matters as much as the pumps. Strainers, wingnut swivel fittings, pressure switch kits, housings and Piranha cartridge kits let a pump be repaired or re-plumbed instead of replaced, as long as the part number matches your model.
Each product card lists flow, pressure, ports and fit for its own part number, so you can compare models side by side before following a link.
