Safety, Compliance, and Performance: The Importance of Accumulator Maintenance

At Rotec, we provide a total life-cycle solution for your hydraulic systems. As the only Parker Certified Accumulator Service Centre in the South West, we are uniquely equipped to keep your operations running safely and efficiently.

What is a Parker Certified Accumulator Centre?

Being a Parker Certified Centre means Rotec has been rigorously audited and approved to provide the highest level of technical service. For our customers, this certification offers several tangible benefits:

Original OEM Parts: We have direct access to genuine spare parts, including Parker, QHP, and Hydac, ensuring your equipment is restored to its original manufacturer specifications.
Expert Recertification: We are authorised to perform full recertifications, including hydrostatic testing and volumetric stretch testing.
Parker Tracking System (PTS): We can use digital tagging to track your assets. This means you can receive automated notifications when an inspection or replacement is due, taking the guesswork out of compliance.
Written Schemes of Examination: We have the expertise to prepare the legally required Written Schemes of Examination (WSE) to ensure you meet UK safety standards.

How Often Does Your Accumulator Need Maintenance?

Under the Pressure Systems Safety Regulations (PSSR) 2000, it is a legal requirement to regularly maintain your hydraulic accumulators. Generally, the following intervals are recommended:

Every 3–6 Months: Visual Inspection & Gas Pre-charge Check

Gas levels naturally permeate over time. Low pre-charge causes the bladder to over-flex, leading to premature failure.

Every 12 Months: External Examination

Checking for corrosion, paint blistering, or mounting issues, especially in harsh marine or construction environments.

Every 5–10 Years: Full Recertification & Internal Inspection

A legal requirement for many systems to verify the structural integrity of the pressure vessel.

Why Choose Rotec Hydraulics?

Maintaining an accumulator is not a DIY task. Opening a pressurized vessel without the correct training and tools can lead to catastrophic accidents, including fluid injection or explosions. Customers choose Rotec because of our:

State-of-the-Art Facilities: Our workshops feature dedicated test rigs capable of testing bladder accumulators from 0.5L up to 54L.
Specialist Accumulator Knowledge: Our engineers are trained by global Fluid Power experts, Parker Hannifin, in all aspects of accumulators.
Sector Experience: We regularly overhaul accumulators from all industries, and can tailor our overhaul accordingly. For example, applying marine-grade coatings to protect against saltwater corrosion for marine accumulators.
Safety First: We ensure your system is fully depressurised and safe before any work begins, protecting your staff and your investment.

Don’t Leave Your Compliance to Chance

A well-maintained accumulator reduces pump wear, saves energy, and prevents costly downtime. Most importantly, it keeps your team safe.

Rotec Completes Critical Refurbishment of Canal Lock Lift Bridge System

Rotec Hydraulics, a leading provider of hydraulic engineering solutions, have completed a recent project involving the removal, overhaul, and refitting of two critical hydraulic cylinders for a Canal Lock Lift Bridge.

The project, which also included the fabrication of a new bespoke clevis frame assembly and the replacement of hydraulic hoses, was executed to ensure the continued safe and reliable operation of the waterway infrastructure.

Due to the age and wear on the existing components, the overhaul was critical. Rotec’s work covered the entire lifecycle of the component replacement, from initial isolation to final commissioning:

Cylinder Removal and Preparation: Rotec engineers worked alongside the customer’s team to safely isolate and remove both hydraulic cylinders from the bridge structure, before transporting them to the Rotec workshop for overhaul.
Comprehensive Cylinder Overhaul: Involved stripping the cylinders, removing seized bolts and eyes, manufacturing new 4-inch rods, and performing repairs and refurbishment on the glands and pistons. The cylinder tubes were polished, and new seal kits were supplied and installed before the cylinders were re-assembled and tested.
Reinstallation and Commissioning: Following overhaul, the cylinders were delivered back to the site. Rotec provided installation assistance, topped up the system with new hydraulic oil, and oversaw the final onsite testing to ensure safe and optimal performance.

The project also encompassed the fabrication of a replacement frame for the cylinder base end clevis.

Clevis Frame Assembly: Rotec reverse-engineered measurements from the existing components to design and fabricate a new clevis frame assembly. The new frame was upgraded with larger side plates for increased durability. The fabrication underwent die-penetrant weld testing to confirm structural soundness.
New Components: The project included the machining and supply of a replacement clevis pin and four new pin locating plates.
Hydraulic Hose Assemblies: Rotec supplied and installed four new replacement hydraulic hose assemblies with stainless steel over braid, all of which were pressure tested prior to commissioning.

“Successfully refurbishing these critical cylinders and simultaneously fabricating a key structural component, all while minimising disruption, underscores our commitment to maintaining essential infrastructure,” commented Dale Lockart, Branch Manager of Rotec’s Stroud Service Centre.

The successful completion of the cylinder overhaul and clevis frame replacement ensures the continued operational efficiency and safety of the Canal Lock Lift Bridge for many years to come.
