The Piston Accumulator – Kocsis KTI Series, including models A40-0231-3K-B-16S, A40-0578-5K-B-16S, A60-1155-3K-B-20S, A60-2310-5K-B-20S, A70-3465-3K-B-20S, A90-4620-3K-B-32S, A120-11550-3K-B-32S, and other Kocsis piston accumulator configurations, is a gas-charged hydraulic energy storage device designed for industrial hydraulic systems, oil & gas equipment, offshore drilling, marine machinery, hydraulic starting systems, and high-pressure applications.
Manufactured by Kocsis Technologies, Inc. (KTI), these piston accumulators store hydraulic energy by compressing nitrogen gas within a pressure-rated cylinder. A movable piston separates the compressed gas from the hydraulic fluid, allowing stored hydraulic energy to be released when required for pressure stabilization, emergency hydraulic power, engine starting, or industrial equipment operation.
Kocsis piston accumulators are available in different pressure ratings, capacities, bore sizes, materials, and connection configurations. Standard product families include 3,000 psi, 5,000 psi, and 10,000 psi configurations, with additional high-pressure and custom-engineered options available for specialized applications.
Unlike bladder-type accumulators, piston accumulators use a precision-fitted sliding piston to separate the gas and hydraulic fluid chambers. This construction allows piston accumulators to be manufactured in various capacities and pressure ratings, making them suitable for demanding industrial applications where hydraulic energy storage, equipment reliability, and pressure control are important.
STX Engineering Solutions supports oil & gas, drilling, offshore, marine, power generation, and industrial customers in Kemaman, Terengganu, Malaysia with the sourcing and supply of Kocsis KTI piston accumulators, A Series and ACB Series hydraulic accumulators, replacement pistons, accumulator seal kits, hydraulic starting system components, and related industrial equipment.

Kocsis Piston Accumulators vs Bladder Accumulators
Piston accumulators and bladder accumulators are both used for hydraulic energy storage, but differ in their internal construction and operating characteristics.
Piston Accumulators use a movable piston to separate compressed nitrogen gas from hydraulic fluid. They are commonly used in hydraulic starting systems, industrial hydraulic equipment, and applications requiring specialized pressure ratings, larger capacities, or particular installation configurations.
Bladder Accumulators use a flexible elastomeric bladder to separate compressed gas from hydraulic fluid. They are commonly selected for applications requiring rapid response, pulsation dampening, hydraulic shock absorption, and pressure stabilization.
Kocsis Technologies manufactures both piston and bladder accumulator configurations, including the A Series and ACB Series piston accumulators and BR Series and TR Series bladder accumulators.
Piston and bladder accumulators should not be considered directly interchangeable without verifying the pressure rating, capacity, discharge performance, mounting arrangement, and hydraulic system compatibility.
Kocsis Hydraulic Starting System Components
Kocsis piston accumulators are commonly used alongside other hydraulic starting system components in industrial engine and marine applications.
Depending on the equipment configuration, associated components may include:
Kocsis Hydraulic Starters – Convert stored hydraulic energy into mechanical rotation for starting compatible industrial engines.
Kocsis Hydraulic Hand Pumps – Manually operated pumps used to recharge hydraulic starting system pressure.
Kocsis Recharging Pumps – Mechanically driven hydraulic pumps used to restore system pressure.
Kocsis Control Valves – Components used to regulate hydraulic fluid flow during starting operations.
Kocsis Soft Engage Valves – Components supporting controlled engagement of hydraulic starter equipment.
Kocsis Piston Accumulators – Store hydraulic energy for starting and industrial hydraulic applications.
Kocsis Replacement Pistons and Seal Kits – Components used during accumulator maintenance and overhaul.
Hydraulic Reservoirs and Accessories – Supporting components used in compatible hydraulic starting systems.
Correct component selection should be based on the existing equipment model, part number, and manufacturer technical documentation.
