ACCULITE
BLADDER ACCUMULATOR

Steelhead Composites AccuLite Series Low Pressure Accumulators range in size from 10 gallons (44 liter) to 40 gallons (151 liter). This unique 300 psi (21 bar) accumulator is a superior alternative to steel accumulators for low-pressure reservoirs used in weight-restricted and mobile applications.

AccuLite series accumulators are all-Aluminum pressure vessels with a rubber bladder inside. The bladder is pre-charged with Nitrogen gas before the accumulator assembly is put in to hydraulic service. A poppet valve in the fluid port prevents extrusion of the pre-charged bladder through the fluid port.

AccuLite series accumulators consist of a fluid port on one end and a gas port on the other. The large fluid port allows easy maintenance and replacement of the rubber bladder. A pneumatic valve on the gas port facilitates periodic re-charging of the Nitrogen gas in the bladder.

FEATURES & BENEFITS
EASIER TO INTEGRATE

Lower weight results in less requirement on structural connections and reduced vibration on ancillary equipment

CORROSION RESISTANT

Increased vessel life in corrosive environments due to naturally corrosion resistant aluminum with powder coated exterior

LIGHTWEIGHT

One-third to one-fourth the weight of traditional steel accumulators
