Application Sections
Mobile Machinery Hydraulic Diagnostics
Modern agricultural and construction machinery relies on complex hydraulic circuits for lifting, steering, and auxiliary functions. Diagnosing issues quickly is critical to minimise downtime and avoid costly repairs. UK service engineers often work in challenging conditions where portable, accurate tools are essential. Monitoring flow, pressure, and temperature helps identify pump wear, valve malfunctions, and system inefficiencies. Real-time data supports preventive maintenance and ensures compliance with OEM specifications. This application underpins reliability and productivity for mobile fleets.
Relevant products:
- HydraPro Hydraulic Test Kits - Comprehensive kits for on-site pressure and flow testing.
Key benefits:
- Rugged design for field use
- Quick-connect fittings for fast setup
- Accurate gauges for reliable diagnostics

Accumulator Gas Charging & Pressure Regulation
Hydraulic accumulators store energy and dampen pressure fluctuations, but incorrect charging can lead to system failure. UK maintenance teams require precise pressure control during charging and testing. Stable regulation prevents over-pressurisation and ensures safety compliance. This process is vital for mobile plant and industrial hydraulic systems.
Relevant products:
- Drastar 092 Series Pressure Regulators - High-flow regulators for accurate pressure control during gas charging.
Key benefits:
- Push-lock handle for secure adjustment
- Excellent stability under varying inlet pressures
- Compact design for service rigs
Case Drain Monitoring
Monitoring case drain pressure is a proven method for detecting early pump wear. Excessive pressure can indicate internal leakage or component failure. UK service engineers use this data to schedule repairs before catastrophic breakdowns. This application improves reliability and reduces maintenance costs.
Relevant products:
- Lake Case Drain Flow Monitors - Detect abnormal flow in return lines to prevent pump damage.
Key benefits:
- Simple visual indication of flow
- Robust construction for harsh environments
- Helps predict pump failure early
Hydraulic Oil Temperature Management
Overheating hydraulic oil leads to varnish formation and reduced component life. Monitoring temperature ensures coolers operate effectively and prevents thermal stress. UK machinery often works in variable climates, making temperature control essential for reliability.
Relevant products:
- Temperature Transmitters - Provide accurate oil temperature readings for system protection.
Key benefits:
- Fast response for dynamic conditions
- Durable in high-pressure environments
- Easy integration with control panels
Filter Differential Pressure Checks
Hydraulic filters protect sensitive components, but clogged filters can cause pressure drops and system inefficiency. Monitoring differential pressure helps schedule filter changes before damage occurs. This application supports preventive maintenance and reduces downtime.
Relevant products:
- CS Instruments Pressure Transmitters - Reliable sensors for differential pressure monitoring.
Key benefits:
- High accuracy under vibration
- Compact design for tight spaces
- Compatible with mobile and fixed systems
OEM Hydraulic Powerpack Commissioning
Commissioning new hydraulic powerpacks requires precise verification of flow and pressure. UK OEMs depend on accurate instrumentation to validate performance and meet customer specifications. This process ensures systems operate safely and efficiently from day one.
Relevant products:
- Dynasonics TFX 5000 Ultrasonic Flow Meter - Permanent installation for continuous flow monitoring during commissioning.
Key benefits:
- Non-invasive clamp-on design
- Handles a wide range of pipe sizes
- Reduces installation time and cost
Hydraulic Test Bench Operations
Test benches simulate real-world conditions to validate hydraulic components. Accurate pressure and flow control is essential for repeatable results. UK service centres rely on robust regulators and indicators for safe and efficient testing.
Relevant products:
- Drastar 092 Series Pressure Regulators - Provide stable pressure control for test bench applications.
Key benefits:
- High Cv for large flow capacity
- Excellent repeatability for consistent results
- Compact footprint for bench setups
Field Service Troubleshooting
Quick diagnostics in the field prevent costly downtime. UK engineers need portable tools that deliver accurate data under challenging conditions. This application supports fast decision-making and efficient repairs.
Relevant products:
- HydraPro Hydraulic Test Kits - Essential for pressure and flow checks on-site.
Key benefits:
- Lightweight and portable
- Comprehensive range of gauges and hoses
- Built for rugged environments
