DELAVAN Product Lines We Repair
Our engineers are trained on the full DELAVAN product range. Below are the major product families we service.
Delavan Fuel Pump Assemblies
Rotary vane and gear pump systems for fuel delivery in power generation and industrial engines. Common issues include internal seal wear, cavitation damage, and fuel contamination leading to flow degradation and pressure loss.
Delavan Hydraulic Actuators & Servos
Linear and rotary actuators for precision control in industrial automation and marine propulsion. Repair focuses on spool stiction, seal leakage, electrical connector corrosion, and response lag in closed-loop systems.
Delavan Pressure Regulators & Relief Valves
Pilot-operated and direct-acting pressure control systems for hydraulic circuits. Failures include stuck spools, cracked valve bodies, spring relaxation, and external leakage at inlet/outlet ports.
Delavan Flow Control Systems
Needle valves, flow dividers, and proportional flow control units for precise metering in aerospace-derived industrial applications. Common issues are needle valve scoring, internal contamination, and electronic driver failures.
Delavan Fluid Filtration & Breather Assemblies
High-efficiency fuel and hydraulic fluid filters with integrated moisture control. Repair and replacement addresses element saturation, differential pressure indicator stiction, and seal degradation affecting system cleanliness.

Common DELAVAN Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DELAVAN equipment arriving at our workshop.
- ✓Fuel pump cavitation and internal erosion damage — Low inlet pressure, fuel contamination, or extended operation with inadequate fuel supply. Delavan pump internals are precision-machined and vulnerable to cavitation pitting when suction conditions degrade.
- ✓Hydraulic actuator spool stiction and sluggish response — Varnish buildup from thermal degradation of hydraulic fluid, corrosion products, or mineral deposits on Delavan spool surfaces. Stiction causes delayed or inconsistent actuation in precision control loops.
- ✓Pressure regulator external leakage and loss of set pressure — Seal degradation in Delavan regulators due to hydraulic fluid incompatibility, thermal cycling in Indian industrial climates, or corrosion of poppet/spool seating surfaces. Loss of system pressure impacts downstream equipment.
- ✓Electronic proportional valve driver circuit failure and no solenoid response — Moisture ingress through corroded connectors, high-temperature component failure on the driver PCB, or open coil windings in Delavan proportional solenoids common in humid Indian industrial environments.
- ✓Flow control proportional valve blockage and erratic metering — Particulate contamination in Delavan needle valve bores, oxidation of fuel or hydraulic fluid at elevated temperatures, or microscopic debris lodged in precision orifices used for flow metering.
- ✓Fuel filter element rapid saturation and pressure drop warning — Delavan filter elements reach bypass conditions prematurely due to upstream contamination sources, water accumulation from condensation in storage or operation, or degraded desiccant breather elements allowing moisture ingress.

What is the typical turnaround time for Delavan fuel pump repair?+
Standard Delavan fuel pump repairs average 7-10 working days from arrival, including disassembly inspection, seal replacement, honing, assembly, and full-flow pressure testing. Critical power plant pumps qualify for expedited 4-5 day repair. We maintain stock of common Delavan seal kits and wear components to minimize lead time. Rush service with overnight delivery available for emergency situations affecting Indian power generation or marine operations.
Can Synchronics repair Delavan proportional solenoid valves and their electronic drivers?+
Yes. We repair Delavan electro-hydraulic proportional valves including solenoid coil replacement, driver circuit repair/replacement, spool polishing, and seal rebuild. We test coil resistance, measure solenoid force, and validate proportional response linearity on calibrated test benches. Electronic driver modules are repaired or exchanged depending on component availability and cost-benefit analysis specific to your equipment vintage and application.
Do you stock Delavan replacement parts and seals?+
Synchronics maintains inventory of high-turnover Delavan components including seal kits, vane and gear sets for fuel pumps, proportional solenoids, filter elements, and pilot-operated valve cartridges. For obsolete or slow-moving parts, we source from authorized Delavan distributors or qualified aftermarket suppliers. We always verify cross-reference compatibility before installation to ensure OEM-level reliability in your industrial systems.
Which Indian industries most commonly use Delavan systems and what are your repair certifications?+
Delavan equipment is extensively used in Indian power generation plants, oil refining, petrochemical facilities, marine shipyards, and aerospace component suppliers. Synchronics is ISO 9001:2015 certified and maintains detailed repair records with component traceability documentation.
