Double Vane Pump
Veljan System Saver Double Vane Pumps provide a sophisticated, all-in-one solution for hydraulic systems requiring two independent flow circuits from a single unit. By integrating essential pressure and flow control valves directly into the pump housing, these units eliminate the need for complex external plumbing and manifold blocks. Built on the high-performance fixed displacement pin vane design, the System Saver Double Pump handles pressures up to 4650 psi (320 bar). This integration significantly reduces the overall installation footprint and potential leak points, making it the ideal choice for compact mobile equipment and space-constrained industrial machinery.
Reliable Dual-Stream Performance and Efficiency:-
Engineered for maximum uptime, these double pumps utilize a rigid bearing arrangement and hydraulic pressure compensation to ensure an outstanding operational life. The signature double-lip vane design provides superior resistance to particle contamination across both flow streams, while dry-lubricant-coated cam rings facilitate excellent cold-start capabilities. With a typical volumetric and mechanical efficiency of 94%, the System Saver Double Pump minimizes heat generation and energy consumption. This high efficiency ensures that both integrated circuits maintain stable, high-pressure performance even at low speeds, protecting downstream components from pressure spikes and ripple.
Streamlined Maintenance and Installation Flexibility:-
The System Saver Double series features a modular cartridge design, allowing for the rapid replacement of internal kits or flow-rate adjustments without major disassembly of the pump or its integrated valving. This "plug-and-play" modularity simplifies inventory management and drastically reduces maintenance downtime. The unit offers exceptional mounting flexibility with various porting configurations and shaft options, including specialized seals for direct gearbox mounting. Compatible with mineral oils and fire-resistant fluids like water glycols, these pumps provide a versatile, pre-engineered power source that simplifies the design and assembly of high-performance hydraulic systems.
