Type S3 Bottom-Repairable Accumulator, 1 Gallon, SAE-20 Port

Description & Features

The Type S3 Bottom-Repairable Accumulator offers a robust solution for industrial fluid energy management. With a 1-gallon capacity and SAE-20 port, it provides reliable performance in demanding applications.

Manufactured by Accumulators Inc, this accumulator features a buna-N bladder and a standard material shell, ensuring durability and long-term use. The design factors exceed the requirements of all standard codes, and each vessel is individually tested and registered.

Key benefits include supplementing pump flow, reducing installed power, providing a standby source of fluid energy, shock absorption, and surge dampening. The bottom repairable style integrates pressure relief design for enhanced safety and cannot be disassembled under pressure.

The operating temperature range for the buna-N bladder is 35deg;F to 160deg;F (optimal) and -10deg;F to 210deg;F (peak). It withstands a maximum operating pressure of 3000 PSI, making it suitable for various high-pressure environments.

With an outer diameter of 6.7 inches and a length of 17.00 inches, this accumulator is both compact and efficient.

Question by: Keith H on Oct 28, 2025, 5:46 PM

what's the temperature range on the bladder for this accumulator? got a application that runs pretty hot

Answer by: Customer Support on Oct 29, 2025, 5:56 PM

Buna-N bladders on these units handle an optimal range of 35°F to 160°F for regular continuous operation. If your system pushes past that, the peak tolerance goes up to 210°F, though you want to stay in the optimal band whenever you can to get the most life out of the bladder. On the cold end, it'll handle down to negative 10°F at peak. So if your application is running hot but staying under 210°F, you're within the rated limits.

got a system that spikes a bit when a valve snaps shut. is this 1 gallon bladder accumulator meant to help with that kind of surge?

Answer by: Customer Support on Sep 19, 2025, 7:28 AM

For surge and shock control, this style is commonly used for shock absorption and surge dampening, along with supplementing pump flow and providing a standby source of fluid energy.

Question by: Peggy B on Sep 10, 2025, 4:44 PM

what gas do you precharge this thing with, and is there anything I gotta watch out for before running it?

Answer by: Customer Support on Sep 12, 2025, 7:02 AM

Dry nitrogen gas is the only approved precharge for this accumulator. Running it without a proper precharge will damage the bladder and can create a serious safety hazard. Before any maintenance or service work, you need to release all system pressure and all stored pressure first. The bottom repairable design includes an integrated pressure relief feature, but it still cannot be disassembled while under pressure, so that step is not optional.

Question by: Merle K on Oct 31, 2025, 10:20 AM

Will this accumulator work alright in a hydraulic system that sees pressures up to 3000 PSI?

Answer by: Customer Support on Nov 1, 2025, 4:34 PM

This Type S3 accumulator is designed to handle a maximum operating pressure of 3000 PSI, making it suitable for your high-pressure hydraulic system.

Question by: Gene P on Nov 17, 2025, 2:43 PM

got a 3000 psi hydraulic setup. is this accumulator rated to handle that, or am i pushin it?

Answer by: Customer Support on Nov 19, 2025, 6:28 AM

Constraint-wise, the maximum operating pressure on this Type S3 is 3000 PSI, so it is intended to run up to that limit.
