Hydraulics Online Energy Expertise: Parker Olaer Fawcett Christie accumulators and accessories for hydraulic system energy management

Olaer Fawcett Christie produces hydraulic energy‑storage technology – accumulators, pulsation dampeners and associated equipment.

The company built its reputation on advanced bladder, piston and diaphragm accumulator designs that delivered reliable performance, long service life and stable system operation. In 2012, Olaer became part of Parker Hannifin, ensuring continued support and global availability of its product families.

Olaer’s expertise centred on hydraulic energy management. Its accumulators were adopted by OEMs and hydraulic system integrators for applications requiring shock absorption, energy storage, pulsation control and emergency power. The brand’s bladder accumulator technology became known for its fast response, high efficiency and dependable performance in demanding environments.

Today, Parker continues to manufacture and support the original Olaer product lines, including bladder accumulators, piston accumulators, diaphragm accumulators, pulsation dampeners and charging kits. These products are used worldwide across hydraulic systems in manufacturing, energy, marine, mobile machinery and industrial processing.

Although Olaer Fawcett Christie no longer operates as an independent brand, its legacy continues through Parker’s global manufacturing network. The Olaer name remains strongly associated with high‑quality accumulator technology that delivers stable operation, long service life and dependable performance in hydraulic systems of all sizes
