Denison Vane Pumps: Single, Double, and Triple Configuration Differences

Blog | July 11th, 2018

Vane pumps work on a well-recognized principle. Mounted off-centre, a rotor spins in its pump housing. A number of bladed, or vanes, are fitted around this central section, and it’s those rotating elements that impart fluid energy. Applied to Denison vane pumps, the principle is the same, but the device architecture is more refined. Starting with single configuration units, what differences divide this hydraulic pumping family?

Denison Vane Pumps: Single Configuration

Hydraulic pumps are versatile beasts. Proving that point, Denison hydraulic pumps adapt to different application demands. By way of illustration, single configuration layouts utilize a cleaner single cartridge design. It delivers a minimum rotational speed of 600-RPM, which jumps up to a high of 4650-RPM when its maximum velocity is called upon for a high-powered fluid transmission application. Then, moving across to a double or triple configured Denison vane pump, everything changes, for those mechanisms have access to cartridges, drop-in vane modules that alter the pump’s flow characteristics.

Drop-in Double and Triple Configurations

By installing different cartridge designs, the flow and pressure handling capabilities of this hydraulic pump alter. There are B, C, D, and E cartridges, which raise the pressure handling parameters of the pump while its flow rate drops. Also, just by moving the cartridges into different configurations, a high flow, low-pressure mechanism can be constructed. Frankly, this easy conversion feature beats out many other hydraulic pump types, which makes sense because drop-in cartridges are common in this fluid-driven field.

Denison-Designed Physical Differences

A single configuration device is smaller, more compact than larger two and three cartridge pumps. For mounting convenience, there are only a mere 4 positions available. Meanwhile, the double configuration mechanism allows thirty-two different mounting options, and the triple pump type delivers an impressive one-hundred and twenty-eight. Gifted with higher pressure containing capabilities and lower flow rates (or vice-versa), multi-stage modular variants also feature volumetric efficiency improvements and lower noise levels. Subsequently, the mechanism’s lifespan improves while undesirable thermal energy buildups dissipate faster. Essentially, the cartridges can be manipulated in ways that significantly reduce energy losses.

Single configuration Denison vane pumps are efficient and capable. All the same, imagine the benefits a hydraulic circuit receives when a double or triple pump configuration installs in the same system. Maintenance costs drop because a new cartridge is easier to replace than an entire pump housing. Better yet, the numerous drop-in configurations add a healthy measure of device customization to the hydraulic circuit. For example, if an actuator is constantly misbehaving, a cartridge swap or substitute can take over and tune the pump’s operational profile until it behaves in an acceptable manner.
