Equipment and spare partsBrowse manufacturers Search by manufacturerDirect engineering supply of genuine VELJAN industrial hydraulics: VT6/VT7 vane pumps, cartridge kits, J9V axial piston pumps, VM vane motors, and control valves interchangeable with Denison Hydraulics.
High-pressure fixed displacement vane pumps engineered with hydraulically balanced rotors for industrial power units, molding machines, and heavy stamping presses. Manufactured strictly to former Denison Hydraulics standards, Veljan single vane pumps feature precision dual-lip vane dynamics that reduce mechanical friction against the internal cam ring contour under continuous high pressure. Designed for quiet operation in heavy plastic processing and metal forming machines, these units deliver high volumetric efficiency up to 94% across varied oil viscosities.
Factory-assembled replacement cartridge groups allowing complete pump overhaul and performance restoration without removing pump casing from machine base. Veljan factory-assembled cartridge assemblies provide rapid on-site maintenance without requiring line disconnection or alignment readjustment. Every drop-in kit incorporates high-tin bronze distribution port plates, micro-finished cam profile rings, and hardened rotors matched to dual-edge vane groups for stable displacement output under peak surges.
Dual-circuit vane pump units driven by a single common input shaft, designed for multi-actuator industrial hydraulic circuits requiring independent flow supplies. Configured with two autonomous pumping elements within a rigid cast housing, Veljan double vane pumps eliminate auxiliary drive splitters and streamline complex multi-actuator hydraulic circuits. Common suction porting simplifies fluid routing while dual independent high-pressure deliveries cater to differential flow demands across working cycles.
Three-circuit high-capacity vane pump stations driven by a unified heavy-duty drive shaft for multi-function metallurgical lines and heavy machine tools. Engineered for heavy continuous multi-function machinery such as metallurgical rolling stands and multi-station shearing machines, Veljan triple pumps integrate three balanced cartridge segments along a high-strength splined drive shaft. This design reduces electric motor footprint while ensuring steady parallel flow to clamping, primary actuation, and filtering loops.
Variable displacement swashplate axial piston pumps engineered for open-loop high-pressure hydraulic circuits demanding precise electro-hydraulic controls. Veljan J9V variable displacement axial piston pumps feature an adjustable swashplate with hydrostatically balanced bronze shoes operating against a nitrided steel cylinder barrel. Available with dynamic load-sensing and proportional pressure control options, these heavy-duty units cut energy dissipation during idle and throttling phases in press hydraulic powerpacks.
High-torque reversible vane hydraulic motors engineered for smooth bi-directional rotation across machine tools, winches, and conveyor systems. Operating with symmetrical hydraulic balance, Veljan VM series vane motors deliver identical bidirectional torque performance in forward and reverse rotation modes. Spring-loaded internal plungers maintain positive vane-to-ring contact even during low-speed crawling down to 50 RPM, preventing stick-slip motion in winch drives and heavy turntable indexers.
Subplate-mounted hydraulic pressure relief, reducing, counterbalance, and directional spool valves meeting ISO 4401 and CETOP standards. Veljan subplate mounted pressure and flow control valves conform to standard ISO 4401 and CETOP footprints for direct drop-in integration onto standardized hydraulic manifolds. Equipped with encapsulated IP65 wet-pin coils, these proportional and pilot-operated valves deliver responsive flow modulation and reliable pressure relief up to 350 bar.
Heavy-duty industrial hydraulic cylinders engineered for metallurgical rolling mills, hydraulic presses, and severe mining conditions. Engineered by the Veljan Hydrair division for grueling metallurgical and industrial mill environments, heavy tie-rod and welded hydraulic cylinders feature micro-honed seamless barrels and high-tensile alloy rods plated with hard chrome (25 µm minimum). Multi-stage polyurethane and chevron packing sets ensure leak-free performance under shock loads.
Our hydraulic application engineers provide thorough technical sizing and circuit verification: displacement calculation from 10 to 270 cm³/rev, operating pressures up to 320 bar, rotation direction (CW/CCW), drive shaft profiles (keyed cylindrical or SAE spline), and SAE 4-bolt mounting flange configurations. We deliver verified cross-reference codes for direct drop-in replacement of aging Denison Hydraulics and Parker pump units without requiring any pipeline or baseframe redesign.
VELJAN hydraulic components deliver rock-solid performance across heavy forging and stamping presses, plastic injection molding machinery, CNC machine tools, metallurgical rolling mills, industrial winches, and mobile drilling rigs thanks to minimal flow pulsation, low acoustic emission, and extreme cyclic endurance.
The hydraulically balanced vane cartridge concept allows plant maintenance crews to perform full pump overhaul directly on-site without disconnecting hydraulic fluid suction and pressure lines. Swapping a factory-calibrated cartridge group (rotor, vanes, cam ring, and side plates) requires under 20 minutes, drastically cutting unscheduled downtime.
Every VELJAN hydraulic pump and motor is precision-machined on automated CNC lines and subjected to 100% bench testing for volumetric efficiency, noise levels, and pressure integrity under full load. All shipments include manufacturer quality test certificates and comply with ISO 9001, ISO 4401 (CETOP), and CE industrial machinery standards.
We supply complete brand-new pumps, hydraulic motors, and full factory-assembled replacement cartridge kits across all displacement sizes, FKM/NBR seal overhaul packages, drive shafts, and mounting brackets directly from the manufacturer with dedicated international logistics and comprehensive 12-month warranty.
