| | Pumps name: Pumps name contain all information about pump material, performance and applied options. This name will be used in all documentation related to the pump. Every pump is also marked with a matriculated number: each pump has its own number. | |

| | Before starting any selection, define the product viscosity, the pressure and the delivery needed and the operation temperature, than proceed to the pump selection. On our experience, an informed and trained customer can easily understand the quality of our product. In this way, following we will try to teach you most important arguments about pumps. Anyway theses "lessons" are just simplified resume of more complex subject. | |

| | The selection of the pump dimension is mainly limited by the viscosity range of the pumped product. The entire selection operation can be easily resumed in this law: the higher the viscosities the less the speed rotation. Naturally this is not the only parameter that must be considered in the pump selection, but can help us focalise what is needed, because give us a rotation speed limit. Temperature influences on the viscosity in inverse ratio, so the same liquid represents different viscosities depending on the temperature of the environment: the higher the temperature the less its viscosity. | _i e_ The delivery capacity of a gear pump suppliers depends also to the work pressure. The entire selection operation can be resumed in a short law: the higher the pressure the higher the delivery losses. The delivery losses can be determinates using the Curves in this catalogue. Viscosity influences also the delivery losses percentage. Pressure must be considered also in the seals selections. Each seal has its own pressure limits, over which it can't work! As example a lip seals will work up to 10 BAR, other else a industrial mechanical seal will work up to 30 BAR. If in doubt, please don't hesitate to contact ouroffice. | |

| | The configuration depends on cost and plantconstruction:thisisjustyourchoice and there are no limitations.You can choose between foot or lantern mounting. | |

| | Pressure is important especially in the calculation of the professional electric motor dimension. Since this time we have just considered the rotation speed of the electric motor, but the absorbed power level is important too in determination of its dimensions.The low for this is that: the higher the pressure the higher it's the absorbed power of the electric motor. Absorbed power is calculated in Kilo-Watt (KW).Viscosities levels influence also the power need by drive unit to spin gears of the pump: the higher the viscosity the higher the absorbed power. | | | |
| | Now, once the pump size and work condition are fixed, we can proceed to selection of products that completely match your requirements. The pump series differ especially for constructions materials,so select the pumps checking its compatibility with the pumped fluid. | The easiest and important point in determination of pump size: the size it self. Find the size that will deliver your product according to operating parameters. Capacity of a gear pump is calculated in cubic centimeter per revolution. | |
