Allweiler® Self-Cooling Centrifugal Pumps

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 coiling. Shanley Pump and Equipment holds current in-house stock of NTT/CTT pumps with nodular cast iron casings.

Centrifugal Pumps are pumps which convert mechanical energy into hydraulic energy by the centripetal force on the liquid. A rotating impeller increases the velocity of the fluid internally while working with the casing of the pump which acts to convert this increased velocity into a pressure increase for flow.

The *Allweiler® NTT Series Centrifugal pump for heat transfer oils 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 due to its self-cooling design during operation.

The NTT series pumps have 150 pound raised face flanges and are available for immediate delivery CTT Flange options are available upon request.
