Product Introduction
Our Koomey accumulator parts lineup encompasses all critical hydraulic, electronic, and sealing components for the complete accumulator unit, including stainless steel pressure gauges (0-3000 PSI / 0-6000 PSI), 5000 PSI check valves, 4-way selector valve repair kits, hydro-electric pressure switch repair kits, 15K piston pressure sensors, explosion-proof audible-visual alarms, rubber mud diaphragms, high-pressure hydraulic fittings, and fluid level indicators. Crafted from 316 stainless steel, high-grade nitrile rubber, brass corrosion-resistant alloys, and explosion-proof electronic components, each part undergoes pressure testing, leak verification, and dimensional inspection to match OEM performance standards.
Functional Capabilities
- Accurate Pressure Monitoring: Stainless steel pressure gauges and 15K pressure sensors provide real-time, precise pressure readings, ensuring operators track accumulator performance with ±1% full scale accuracy.
- Leak-Free Pressure Retention: 5000 PSI check valves and rubber mud diaphragms prevent hydraulic fluid backflow and leakage, maintaining stable accumulator pressure for reliable BOP operation.
- Reliable Valve Control: 4-way selector valve repair kits restore smooth valve operation, eliminating sticking or malfunction that disrupts hydraulic fluid distribution.
- Safety Alert & Protection: 24VDC explosion-proof audible-visual alarms alert crews to pressure anomalies or system failures, preventing uncontrolled well situations.
- Secure Hydraulic Connections: High-pressure brass fittings and stainless steel nipples ensure tight, durable connections, resisting vibration and corrosion in harsh oilfield environments.
- Fluid Level Monitoring: Gallon fluid indicators track hydraulic oil levels, preventing low-fluid damage to accumulator pumps and components.
Structural Design Features
- API Spec 16D Compliance: All components meet global BOP control system safety standards, ensuring regulatory approval for onshore and offshore drilling operations.
- Exact Koomey OEM Fit: Precision-machined dimensions and OEM part number matching ensure seamless replacement, cutting on-site installation time by up to 50%.
- High-Pressure Durability: Valves and gauges rated for 5000 PSI maximum working pressure, withstanding extreme hydraulic loads without deformation or failure.
- Corrosion Resistance: 316 stainless steel and brass construction resists oilfield moisture, chemicals, and H₂S exposure, extending service life to 8,000+ operating hours.
- Explosion-Proof Electronics: Audible-visual alarm systems and pressure sensors are certified for hazardous oilfield locations, ensuring safe operation in volatile gas environments.
Applicable Operating Conditions
These Koomey accumulator components are engineered to perform reliably in rigorous drilling scenarios, including:
- National/Koomey hydraulic accumulator units for BOP control systems
- Onshore/offshore drilling rigs with API 16D compliant well control equipment
- High-pressure hydraulic systems operating at 3000-5000 PSI for BOP actuation
- Hazardous oilfield environments requiring explosion-proof electrical components
- Routine accumulator maintenance, emergency BOP system repairs, and API 16D recertification
Maintenance & Service Recommendations
- Inspect pressure gauges and sensors for calibration drift every 2,000 operating hours; recalibrate or replace components to maintain ±1% pressure accuracy.
- Check check valves and mud diaphragms for wear, cracking, or leakage quarterly, replacing worn parts to preserve pressure retention and prevent fluid loss.
- Lubricate selector valve components and inspect repair kit seals every 3,000 hours to eliminate sticking and ensure smooth valve operation.
- Test explosion-proof alarm systems and pressure switches monthly, verifying functionality to detect system anomalies early.
- Clean hydraulic fittings and inspect for corrosion or damage every 6 months, replacing worn fittings to maintain tight, leak-free connections.
- Verify API 16D certification documentation for all parts prior to installation to ensure full regulatory compliance for well control operations.

Field Failure Repair Case Studies
Case 1: Koomey Accumulator Pressure Gauge Inaccuracy
A Koomey accumulator displayed erratic pressure readings due to a faulty 4″ 0-3000 PSI gauge (GA43000H). Installing a new stainless steel OEM-matched gauge restored accurate pressure monitoring and compliance.
Case 2: Check Valve Leakage & Pressure Loss
A 1/2″ check valve (401508) failed to retain pressure, causing gradual accumulator pressure drop. Replacing the 5000 PSI check valve eliminated leakage and restored stable pressure retention.
Case 3: Selector Valve Malfunction & Fluid Distribution Failure
A 4-way 1″ selector valve stuck in operation, disrupting BOP hydraulic fluid flow. Installing a selector valve repair kit (13304199) fixed valve sticking and restored normal fluid distribution.
