How to select the right pump drive for an application – learning the basics. It can be quite difficult to find the right pump drives for your particular needs. There are many different types of power take-off units (PTOs), and it may seem overwhelming to try to choose the right one that fits your needs. jbj Techniques Limited make it easier for you. In this article, we’ll take a look at multiple power take-offs and pump drives, and how you can select the right type of pump drive for your application. Whether you’re running an industrial plant, or simply looking for the right power take-offs for your heavy machinery, heavy plant, mobile applications, this guide is sure to help you select the right pump drive for your needs. Six basic considerations for selecting a pump drive: Let’s begin with the basics. When engineering any new pumping or hydraulic system with pump drives and power take-offs, there are six basic things you must consider – before you begin creating blueprints, plans, and other project details. Here’s a quick overview of each one. 1} The number and type of pumps required. No two projects are the same. The type of pumps – and the number that you need – will vary in each and every engineering project. This depends on the performance statistics and overall dimensions of the pumps, as well as the pipework through which the fluid will travel. With both of these factors understood, it should be quite easy to establish a maximum centre distance, and choose units that will deliver

Pumps may be stressed past their operating limits, resulting in eventual product failure. 2} Maximum torque output requirements for each pump. After you have done the basic mathematics to determine the type of pumps that you need, it is time to consider your maximum torque output requirements. You will need to make sure that this number is below the maximum value of each of your pumps, to ensure smooth and steady operation....

How to select the right pump drive for an application – learning the basics. » Inertia of the machine to be driven A high-inertia machine will typically put more stress on a gearbox, due to the heavy torque loads and weight applied to the unit during each rotation. The heavier the pump or other machine is, the more robust the gearbox will have to be. Special bearings and housing designs may be required to accommodate these high loads on the input shaft. This guide is a helpful resource for analysing inertia, engine type, horsepower, and more. » Peak torque requirements Care should be taken not...

How to select the right pump drive for an application – learning the basics. » Allow multiple pumps or other devices to be driven with one prime mover. Splitter gearboxes allow for multiple types of pump to be driven by a prime mover with a high enough capacity. This includes traditional pumps, vane pumps, screw pumps, and more. Of course, their usefulness is not only limited to pumps – they can drive a variety of other devices as well. » Reduce planning complexity and prime mover requirements. By using a single engine and a multiple power take-off, the mechanical operations of a given product...

How to select the right pump drive for an application – learning the basics. Con » Can’t be used to unite multiple prime movers. This is one of the biggest drawbacks of a single pump drive. Being able to use one pump drive to accept power from multiple motors is very useful when designing and implementing projects. » Not ideal for parallel pumping. Parallel pumping is gaining acceptance in the world of hydraulics and plant design. It allows for less stress on each individual pump, and faster delivery of fluids via smaller pipes. Compared to multiple power take-offs, single pump drives are not ideal...
