ENGINEERING & DESIGN
Pre-Charge Verification
Measuring N2 gas pressure (P0) using specialized charging sets ensures proper shock absorption and energy storage.
FLOWART // ACCUMULATOR & N2 CHARGING
Hydraulic Accumulator Service & N2 Gas Pre-Charge
Accumulators provide peak flow supplementation, shock absorption, and emergency power. Regular Nitrogen (N2) pre-charge monitoring is essential for safety and efficiency.

Frequently Asked Questions
Natural micro-permeation, worn gas valves, or bladder degradation reduce pre-charge pressure.
Only pure dry Nitrogen (N2) gas must be used. NEVER use oxygen or compressed air due to explosion risk!
Pre-charge pressure should be checked every 6 months or whenever shock absorption degrades.
