SHURFLO accumulator tank 24 oz pre-pressurized, 30 PSI pre-charge — smooths pressure, reduces pump cycling

The PENTAIR SHURFLO 182-200 is a 24 oz pre-pressurized accumulator tank engineered to stabilize freshwater pressurized systems by storing water under a 30 PSI factory pre-charge and smoothing pressure fluctuations up to 125 PSI.

This compact accumulator tank is built to make freshwater pump systems run quieter, cycle less often, and deliver steadier flow. It uses an internal diaphragm and a factory-set air pre-charge to hold a small volume of pressurized water that reduces rapid on/off pump cycles, diminishes faucet pulsation, and lowers pressure spikes. Because it cuts repeated pump starts, the tank is especially useful for battery-powered, mobile, and off-grid systems where conserving power and extending pump life matter.

How does the SHURFLO accumulator reduce pump cycling and protect my pump?

The accumulator provides a buffer of pressurized water between the pump and the system so small draws are met from the tank instead of starting the pump. This reduces the number of full pump starts and the stress those starts place on switches and motor windings.

• Stores 24 oz of pressurized water to cover short draws
• Diaphragm separates air and water to prevent waterlogging
• Fewer pump cycles extend switch and motor life

Will this tank improve water flow and stop faucet pulsing?

Yes — the internal diaphragm and pre-charge smooth out rapid fluctuations in pressure that cause pulsing or surging at fixtures. The result is a steadier stream and more comfortable use at taps and shower heads.

• Reduces short-term pressure swings that produce pulsation
• Delivers more consistent flow during intermittent draws
• Helps maintain steady delivery for multi-fixture use

Is the 182-200 compatible with my system pressure range and applications?

The accumulator is factory pre-charged to 30 PSI and designed to work in systems requiring 20–125 PSI, making it suitable across many RV, marine, industrial, and utility freshwater systems. Its compact footprint and durable construction allow flexible mounting in confined or mobile installations.

• Factory pre-charged at 30 PSI for immediate use
• Compatible with pumps and systems rated from 20–125 PSI
• Compact 24 oz size fits tight spaces in RVs and boats

How will this tank help save power and reduce noise in off-grid setups?

By meeting small draws from stored pressurized water, the SHURFLO accumulator prevents frequent pump startups that consume battery power. Fewer starts also reduce mechanical noise and vibration from pressure switch-controlled pumps, improving onboard comfort.

• Minimizes repeated motor starts to conserve battery energy
• Less switching reduces audible pump noise and vibration
• Ideal for solar, battery, and quiet marine installations

Who is this for: The PENTAIR SHURFLO 182-200 accumulator tank is aimed at RV owners, boaters, off-grid homeowners, and technicians managing small to medium freshwater pressure systems who want quieter operation, fewer pump cycles, and steadier water delivery. It's a practical add-on for anyone seeking a low-maintenance solution that improves pump longevity and fixture performance without major system changes.
