The *Allweiler® NTT Series Centrifugal Pump for heat transfer applications is an ideal solution for the handling of organic heat-transfer oils. The NTT"s unique self-cooling design eliminates the need for additional cooling in any form due to its self-cooling design during operation.

At Shanley Pump and Equipment, Inc. we stock a complete line of *Allweiler® NTT thermal oil pumps. These are horizontal centrifugal pumps that are capable of pumping thermal oil at 660° degrees F (350°C) at up to 6,400 GPM with up to 430" feet of head and require no additional cooling.

The oldest German pump manufacturer, founded in 1860, Allweiler GmbH is today the European market and technology leader in fluid handling solutions for shipbuilding, power generation and special industrial applications. Our product portfolio is unrivaled in the industry and includes centrifugal, propeller, screw spindle and progressive cavity pumps, as well as complete pump systems. We also manufacture peristaltic pumps and macerators. In addition to our Allweiler-branded pumps and systems, we sell the pumps and solutions of our sister company Zenith - gear pumps.

We’ve built our success on putting our customers’ needs as the top priority in the development of every individual Allweiler product. Our customers benefit from a deep knowledge of pump technologies and expertise in fluid handling applications that has grown over generations. They know our pumps are precisely manufactured to address specific applications areas and trust the quality and reliability of Allweiler pump performance. We back our pumps with expert, personal, onsite and comprehensive services.

Allweiler"s NTT single-channel centrifugal pumps have a practical modular design and are designed for mounting a drive unit with a base plate (cast iron or steel), DIN EN 733. Ideal for pumping high-temperature oils in various industries. The lineup is represented by a wide selection of dimensions for the selection of the optimal option. One- or two-stage design, mechanical shaft seal, efficient self-cooling. The outlet is directed radially upward, the suction is coaxial, the bearings are maintenance-free. On request, it can be equipped with a spacer coupling. Three-phase squirrel-cage motors on feet are used as a drive in the standard.

The NTT, NBT and NIT product series are ideal for moving mineral-based thermal oils. Their mechanical seals are located behind a heat barrier, where they are protected from high temperatures. The result is that simple standard gaskets (antimony-carbon/SiC) have a very long service life when used in the pumps. All three types are also available as two stage versions with the same external dimensions, making them ideal for small flow rates with high delivery head.

The ALLHEAT series gives plant operators centrifugal pumps that were designed specifically for high-temperature applications employing low-viscosity heat carriers like synthetic thermal oils and hot water. These pumps have unrivalled versatility; they forgo external cooling and are extraordinarily durable in continuous operation. Very little heat is lost by the entire system and maintenance intervals are usually longer than twelve months even when operated continuously under difficult conditions. The CBWH and CIWH series are the world"s only block-type pumps with an air-cooled shaft seal that pump hot water above 183 °C/361 °F without external cooling. Due to their maximum oil temperature of 400 °C/752 °F, CTWH, CBWH, and CIWH 350°C/662 °F are also ideal for modern applications like solar power stations.

The fluids pumped must have lubricating properties and should not contain any solids or particles, as the non drive end bearing and mechanical seal is lubricated by the pumped liquid.

These pumps are further equipped with a safety stuffing box and throttling area in front of the mechanical seal. In case of a seal failure this prevents the pumped liquid from emerging in a hazardous quantity or manner. With drain connection adequate piped up, the safety requirements of DIN 4754 are exceeded. (The pumps have a drain connection to ensure that any seepage past the shaft sealing can be safely drained through this connection).

We can service all manufacturers pumps, sourcing spares from the OEM and utilizing reverse engineering when parts are out of stock or obsolete on older units.

The German company ALLWEILER over its long history has come a long way from a small factory for the production of hand pumps to a large concern with representative offices in all parts of the world. The main secret of success is the use of high quality and reliable materials. That is why the company has a foundry that produces blanks for ALLWEILER pumps. The ALLWEILER company specializes in the production of pumps of the following types: centrifugal, vortex, screw, eccentric screw, screw, two- and three-screw, hose, propeller, rotary, rotary with a magnetic drive. The company"s products have found application in almost all areas of industry: oil production, energy, chemical industry, sea transport, water treatment and water treatment.
