What Accumulators does

Accumulators, Inc. is a privately held Houston, Texas-based manufacturer specializing in hydro-pneumatic accumulators — pressure-storage devices that use compressed nitrogen gas to store hydraulic energy and discharge it on demand across bladder, piston, and diaphragm configurations. The company's technology stack centers on gas-compression and fluid-displacement mechanics, with proprietary extensions including patented float accumulators for extreme-temperature and subsea/offshore service, transfer barrier accumulators for hydrostatic pressure compensation, and a comprehensive accessory ecosystem spanning gas bottles, safety blocks, nitrogen gas boosters, charging/gauging equipment, mounting hardware, racks and manifolds, and maintenance tools.

The business operates as a sales-led B2B industrial company targeting oil and gas, wind energy, off-road and mobile equipment, and subsea/offshore verticals, with customers including Fortune 500 oil and gas companies, the US Department of Defense, and the US Coast Guard. Revenue is generated primarily through quote-based direct sales of core and specialty accumulator units, supplemented by aftermarket parts, factory and on-site repair, specialty coatings (Phenolic, Electroless Nickel, Marine Epoxy, All Stainless), and training programs. Distribution combines direct enterprise sales with a worldwide network of distributors, with no e-commerce or self-serve channel; orders originate via website RFQ tool, phone, fax, or email. Pricing is custom and quote-based, with multi-year contract billing cadence and no publicly disclosed tiers.

Operations are consolidated at an 11-acre purpose-built West Houston campus opened in 2016, housing advanced logistics, assembly, testing, and training capabilities. The company is independently owned and operated with no venture capital or private equity backing, was co-founded in 1987 by Murry Allewitz and Jeffry Schneider, and is currently led by Jeffry Schneider (CEO), Scott Schneider (President and COO, joined 2006 from McMaster-Carr), and EVP Richard T. Kendall (50+ years industry experience). Quality and design credentials include ISO 9001, ASME U and R stamps, DNV, ABS, Lloyd's, CRN, CE, and AS1210 approvals, enabling specification into oil and gas, defense, maritime, subsea, and pharmaceutical-adjacent applications.

Core offering

Accumulators, Inc. designs, manufactures, and sells hydro-pneumatic accumulators—bladder, piston, and diaphragm types—that use compressed nitrogen gas to store hydraulic energy and release it on demand for industrial hydraulic systems. The product portfolio is supported by a range of accessories (gas bottles, safety blocks, racks and manifolds, charging/gauging equipment, mounting equipment, maintenance tools, and nitrogen gas boosters), specialty variants (Float Accumulators, Transfer Barrier Accumulators, coated/special-service units), and factory/on-site repair, refurbishment, coating, and training services sold to oil and gas, wind energy, defense, and industrial equipment customers.

Product overview

Accumulators, Inc. is an independently owned manufacturer specializing in hydro-pneumatic accumulators for industrial hydraulic applications. The core product portfolio consists of three main accumulator types—Bladder Accumulators, Piston Accumulators, and Diaphragm Accumulators—each using compressed nitrogen gas to store hydraulic energy. The product line is complemented by a comprehensive range of accessories including Gas Bottles, Float Accumulators, Transfer Barrier Accumulators, Safety Blocks, Nitrogen Gas Boosters, Charging and Gauging Equipment, Mounting Equipment, Racks and Manifolds, and Maintenance Tools. The company also provides value-added services including factory and on-site repair, flushing, specialty coatings (Phenolic, Nickel Plated, Marine Epoxy, All Stainless), and training programs. All products are designed, assembled, and tested in Houston, Texas with ASME certification and ISO 9001 quality standards.

Products and services

• Bladder Accumulators Durable and efficient hydro-pneumatic accumulators with a seamed molded rubber bladder mechanically attached to a high-strength metal shell; suited to blowout preventer systems, pulsation dampening, hydraulic power units, fluid volume compensation, wind energy, and other industrial applications. Sold to oil and gas, wind energy, and industrial customers.
• Piston Accumulators Highly customizable hydro-pneumatic accumulators using a polished and honed cylinder ID with a floating piston to separate gas and fluid sides. Handle hotter and colder temperatures than bladder types, support larger volumes, higher pressures, and higher temperatures, and are offered with quick quoting and delivery for industrial hydraulic customers.
• Diaphragm Accumulators Compact hydro-pneumatic accumulators with a one-piece molded rubber diaphragm mechanically sealed by a high-strength metal shell, offering a liquid/gas ratio up to 6:1. Targeted at low-volume pulsation dampening and fluid storage in off-road and mobile hydraulic markets; mountable in any orientation.
• Float Accumulators Patented hydro-pneumatic accumulators built for low-cycle applications requiring extreme temperatures or harsh environments, minimizing fluid contamination and maintenance damage, and particularly suited to subsea and offshore service. Must be mounted vertically.
• Transfer Barrier Accumulators Specialty bladder accumulators whose gas end incorporates a connection point for permanent fluid or inert gas connection via hose or tubing; used for subsea hydrostatic pressure compensation, separation of two immiscible fluids, and remote nitrogen precharge adjustment.
• Special Service Accumulators Custom accumulator variants with multiple coating options including Water Service (Phenolic coated), Nickel Plated, Extreme Service for offshore drilling, and All Stainless models; custom engineered for corrosive, offshore, and high-water-content hydraulic applications.
• Gas Bottles ASME code-stamped pressure vessels for storing high-pressure nitrogen gas or increasing usable volume of separate accumulators, available from 1 quart to 50 gallon capacity and up to 10,000 PSI pressure rating.
• Safety Blocks Multi-functional isolation valves installed between accumulators and operating systems, integrating 90-degree ball valves, manual relief valves, and optional pressure gauges to provide maintenance isolation and emergency shut-off.
• Nitrogen Gas Boosters Devices that boost nitrogen gas pressure directly from cylinders to outlet pressures up to 10,000 PSI using shop-air driven or direct-nitrogen configurations, with automatic stop/restart control at set pressure to deliver non-contaminated outlet gas.
• Charging and Gauging Equipment Equipment and kits for precharging accumulators with nitrogen gas and monitoring system pressure, available in kits for 3000, 5000, 6000, and 10000 PSI pressure ratings and including permanent-mount pressure monitors.
• Mounting Equipment Rubber-lined mounting collars, bases, and brackets for safely securing bladder, piston, and diaphragm accumulators in various orientations.
• Racks and Manifolds Multi-accumulator mounting systems that combine accumulators in parallel configurations to provide the fluid volume needed for BOP closing systems, emergency power, and other high-demand hydraulic applications.
• Maintenance Tools Tools for precharging, maintaining, and repairing accumulators, including pull rods, spanner wrenches, valve core tools, torque wrenches, and complete maintenance kits.
• Coatings and Special Service Options Internal and external coating configurations including Phenolic, Electroless Nickel, Marine Epoxy, and All Stainless options, plus other special service configurations for corrosion protection in offshore, chemical, and high-water-content hydraulic applications.
• Factory and On-Site Repair Services Full refurbishment, bladder and seal replacement, coating services, inspection, recertification, and nitrogen precharging for accumulators and competitor products, delivered in-factory at the Houston campus or on-site.
• Training Programs Hands-on and webinar training courses covering basic accumulator knowledge, application sizing, repair, maintenance, troubleshooting, and corporate overview seminars, leveraging the company's expanded on-campus training capabilities.
