3000 AND 6000 PSI BASIC PERMANENT MOUNT PRESSURE MONITORS

  • These units are intended to be mounted permanently on the valve stem of the accumulator to monitor hydraulic system pressure. Nitrogen precharge may only be measured when hydraulic line pressure is zero PSI.
  • We recommend the use of a liquid-filled gauge for high-cycle shock applications.
  • Accumulator gas valve must be removed prior to installation. Ensure all accumulator pressure has been removed before beginning installation.
  • Custom and digital assemblies are available

Nitrogen Regulator

We recommend a nitrogen regulator to anyone precharging an accumulator. The regulator ensures that nitrogen is added to your accumulator at a safe rate, which protects the bladder from damage as well as keeps the air temperature inside your accumulator from rising during compression. Use of a nitrogen regulator is an essential safety factor.

We stock several different types of nitrogen regulators compatible with our accumulators. Please contact us for more information.

Most hydraulic accumulators need to be precharged with dry nitrogen gas before operation. Accumulators, Inc. nitrogen gas boosters are designed to boost gas pressure directly from nitrogen cylinders to outlet pressures as high as 10000 psi. Our unit ensures maximum outlet pressure will be maintained even if the pressure in the nitrogen cylinders drops as low as 500 psi.

Our booster is a driven by a typical industrial-style shop-air compressor, typically between 70 and 100 psi. If compressed air is not available, the booster can also be driven directly by the nitrogen cylinders. In the shop-air drive mode, non-contaminated outlet gas is assured through complete dual-vented separation from the drive section. The high pressure section of the booster is cooled by the drive exhaust gas and requires no lubrication. Valves and gauges are stainless steel and are line-mounted to the booster, which features a painted, aluminum tube frame with carry handles.

CONTROLS INCLUDED

  • Single acting double drive gas booster configuration.
  • Automatic control to stop/restart the booster when the outlet pressure exceeds set point; pre-selected pressure up to 6000 psi (adjustable, depending on model).
  • Manual start and stop
  • High pressure air controls (HP regulator, relief valve, inlet & regulated outlet gauges and on/off valve)
  • Adjustable safety relief valve
  • Gas inlet and outlet gauges

SPECIFICATIONS

  • Dimensions: 30”L x 12”D x 12”H
  • Weight: 60 pounds
  • Maximum outlet pressure: 6000, 7500, or 10000 psi
