在与泵的开发和生产相关的所有领域中，液压工程师必须处理的任务在最近几十年发生了显着的变化：从或多或少不受限制的部件设计到由制造技术决定的设计角色。这些总的趋势伴随着与市场需求变化有关的发展。这是针对三种特定的泵类型进行证明的。以供暖循环泵为例，从各个方面阐述了节能要求的后果。不断增长的环境意识是一个挑战，扩大目前有效的操作限制的无密封泵和智能监控系统的发展。指出锅炉给水泵的发展与机组的大型化密切相关。可用性和可靠性，以及就大型泵而言的效率，一直是并且仍然是主要标准
As in all areas relevant to the development and production of pumps the tasks the hydraulic engineer has to deal with have undergone a remarkable change in recent decades: from a more or less unrestricted design of components to design roles dictated by manufacturing techniques. These general trends are accompanied by developments related to changes of the market requirements. This is demonstrated for three particular pump types. The consequences of the demand to save energy-with all the different aspects-are described for the example of heating circulation pumps. The still growing environmental awareness is a challenge for an enlargement of the presently valid operation limits of sealless pumps and for the development of intelligent monitoring systems. It is demonstrated that the developments in the field of boiler feed pumps are closely related to the growing unit sizes. Availability and reliability, and as far as very large pumps are concerned the efficiency, have always been and still are the dominant criteria
