Pumps for heat transfer technology Centrifugal pumps Regenerative turbine pumps Series TOE-G and TOE-M Series NPY-MK and CY-MK Consistent design modular system with spiral housings Tried and tested and compact close-coupled pumps with top/top housings and magnetic coupling Choose from six different designs with mechanical seal or magnetic coupling. Developed for circulating organic or synthetic heat transfer oils in heat transfer systems in accordance with DIN 4754, as well as hot water. Developed for transporting and circulating organic or synthetic heat transfer oils and hot water....

Find the right pump for your system Choose the best solution from six ranges Each heat transfer system is unique in its own way - on some, the sealing principle is key, on others the vertical installation frame or perhaps the special properties of the medium. Series TOE-G with mechanical sealing With the heat transfer pumps from Speck Pumpen you can choose from six ranges with different characteristics and find the best solution for your system. Different characteristics Series TOE-M with magnetic coupling »» Water up to 160 °C »» Water up to 180 °C on request »» Oil up to 350 °C In...

Minimal spare parts stock and flexibility thanks to the modular system Thanks to the modular system with consistent design, many components are identical and interchangeable across the six ranges. This means minimal spare parts stock. Series TOE-G with mechanical sealing And it also guarantees complete flexibility, as replacing pumps and components or retrofitting to a different design is easy. Interchangeable housings two bearing brackets for all frame sizes Only »» Bearing bracket 360 for 12 frame sizes identical and interchangeable »» Bearing bracket 470 for 7 frame sizes identical and...

High operational safety, optimal design and service-friendly Robust construction Optimised for synthetic heat transfer oils Clever temperature management Torsion-resistant casing cover Dry-run safety function for the mechanical seal Synthetic heat transfer oils are being used more and more frequently due to the benefits they offer. However, low-boilers develop in the synthetic oils over time in form of gas bubbles, can lead to dry-running on the mechanical seal. Optimised cooling of ball bearings, mechanical seal and sleeve bearings The air flow generated by the fan blade on the coupling...

Also suitable for critical applications Optimal design Mechanical seal with quench For media, which are prone to crack pro­ duct formation on the sealing surfaces of the mechanical seal, versions with quench are available. Energy efficiency High energy efficiency secures a lasting competitive edge. Speck Pumpen offers the important criteria for energy-optimised design: Seamless range of sizes, highly efficient impellers, switching of impellers for the best design at the operating point and natural motors in accordance with IE2. Simple installation All six series are extremely...

Longer lifetime There are effects, which have little or no relevant impact on smaller designs, but lead to increased wear in larger pumps. Speck Pumpen offers larger pumps with special designs to guarantee a longer lifetime: Housing with centreline mounting and double spirals. Centreline mounting relieves strain from the bearings and coupling Double spirals remove strain from the sleeve bearings Radial forces are applied directly on the sleeve bearings. The forces increase with higher impeller diameters and higher speeds. This is why the sleeve bearings on larger pumps with single spiral...

Regenerative turbine pumps with magnetic coupling Extremely compact, robust, durable and safe Type-related properties Due to their design, regenerative turbine pumps have different properties than centrifugal pumps and are the better choice for certain applications. The peripheral impeller transfers the hydraulic output through momentum exchange. They achieve relatively high pressures with smaller volume flows, which means that the characteristic curve also runs relatively steep. They belong to the pump types which offer the option of changing the conveying direction through right-left run....
