The Driving Force in Your Cooling Water System T u b u l a r C a s i n g P u m p s

More than 120 years’ tradition in the design and construction of pumps, valves and relevant systems for industrial and process-engineering applications, building services, water, environmental and power engineering. Over six decades in the production of tubular casing pumps for fossil-fueled and nuclear power plants. That adds up to many years of experience and comprehensive know-how in pump engineering. With more than 12,500 employees at 30 production facilities and more than 100 sales companies and offices around the world, we are genuinely customeroriented, thoroughly flexible and fully cognizant...

(e.g., bearing temperatures) and its vibration and noise levels. Alternatively, model experiments can be run and the results extrapolated to full size by approved methods. With regard to the efficiency of cooling water pumps, it is particularly important to optimize their inlet conditions, in which case model inlet experiments yield reliable data for use in optimizing the geometry of the intake chambers. In addition to the competent advice and guidance rendered, you naturally can also count on us to install and commission your cooling water pumps. And afterwards, our Service Division will remain...

Maintaining a power plant’s full performance capacity despite variable operating conditions demands a lot of flexibility – and constant efficiency – on the part of the cooling water pumps. Major factors of influence include the existing inlet conditions and possible fluctuations in flow rate and head. In order to stay both cost-effective and situation-appropriate, KSB’s modular cooling water pumps are available with a choice of hydraulic variants and control modes. Moreover, the vertical tubular casing models are designed for wet or dry installation, and their discharge elbows can be installed...

The pump’s inlet conditions are a crucial factor for smooth operation. The nature of the inflow into the intake chambers as well as their design are of particular importance. An optimized intake chamber must feed the medium to the impeller uniformly and irrotationally all around. Owing to the correlation between the equipment costs on the one hand and the structure costs on the other, the pump supplier and building contractor need to jointly conduct a holistic situation analysis I n t a k e C h a m b e r M o d u l e • Open intake chamber, unlined h1 = minimum fluid level above the pump to preclude...

Pre-swirl control • pre-swirl control of approach flow • particularly well-suited to cases in which pronounced variation of head is anticipated in combination with relatively constant flow rates, e. g., to compensate for tidal flow or for combined operation (cooling tower/fresh water) C o n t r o l M o d u l e Speed control • can be used wherever the pump is driven by a variablespeed electric motor or diesel engine • optimal means of control for systems characterized by low static head, as it allows fine-tuning and pump operation at peak efficiency Blade pitch adjustment/control • infinitely...

For a cooling water pump to achieve high efficiency, all its various components must interact without a hitch. Consequently, KSB’s modular system includes an appropriate choice of bearings, casings and materials for a broad diversity of service conditions. Good performance means safety, reliability, availability, quality and economic efficiency - not to forget know-how, experience and competence. KSB’s modular system is built up around just such characteristics. For standardized and tailor-made solutions. Give us a call. We’ll help you keep your cool.
