1 PN 16/PN 25 Volute Centrifugal-s for Heat Transfer Media Thermal Oil up to 00 C Hot Water up to 7 C Series NTWH/CTWH Series NBWH/CBWH Series NIWH/CIWH Application For circulating heat transfer media such as thermal oil or hot water in heat transfer systems (DIN 75 and 752). The media to be pumped may not contain any abrasive constituents or chemicalliy attack the pump material. Series The NTWH, NBWH, and NIWH series of pumps are designed for organic and synthetic heat transfer oils up to 350 C. Series CTWH, CBWH, CIWH can be used up to 00 C. The series NTWH, NBWH and NIWH (PN16) can be used with hot water at temperatures of up to 13 C and series CTWH, CBWH and CIWH (PN25) at temperatures of up to 7 C. Size CTWH -/1 (ALLHEAT 0) is approved for pumping heat transfer oils only. The application limits with regard to temperature, pump series and housing material are specified in the table "Application limits" and in the diagram "Pressure/temperature limits depending on the housing materials". Design Series NTWH/CTWH: Process models of a horizontal volute centrifugal pump. Single-flow, single-stage with optimised bearing support (consisting of housing cover incl. throttle/cooling section and bearing support). Shaft bearing consisting of a silicon carbide or carbon sliding bearing lubricated by the pumped medium on the pump side and a grease-lubricated deep groove ball bearing on the drive side. Volute casing with cast-on pump feet. Series NBWH/CBWH: Block model of a volute centrifugal pump. Single-flow, single-stage with optimised bearing support (consisting of housing cover incl. throttle/cooling section and bearing support). Plug-in shaft and motor shaft are rigidly connected to each other. Shaft bearing consisting of a silicon carbide or carbon sliding bearing lubricated by the pumped medium on the pump side and the grease-lubricated deep groove ball bearing of the drive motor. Motors with axial thrust bearings. Spiral casing with cast-on pump feet. Horizontal or vertical installation, however, not with motor arrangement facing downwards. Series NIWH/CIWH: In-line model of volute centrifugal pump, other details as for series NBWH/CBWH. Shaft sealing Uncooled, balanced or unbalanced, maintenance-free mechanical seals acc. to DIN EN The shaft seal is dependent on the direction of rotation. A safety gland and a subsequent throttle/cooling section are provided upstream of the shaft seal.

Due to the modular design, spare parts management is simplified. Dismantling of insert unit NTWH/CTWH Where a shaft coupling with a spacer element is used, the insert unit can be removed towards the motor side, whilst the volute casing and the motor may remain on the base plate and the pipes connected to the volute casing. Dismantling of drive unit NBWH/CBWH/NIWH/CIWH During dismantling of the drive unit, the volute casing can remain in the pipeline. Shaft coupling and contact protection Elastic shaft coupling acc. to DIN 70 with or without spacer element. A coupling protection is supplied as a contact protection acc. to DIN EN 29 (DIN 31), where the scope of delivery includes a pump, base plate and shaft coupling. Couplings with spacer element in rotationally flexible, double cardanic design (proper base plate required). We recommend the use of double cardanic couplings under the following operating conditions: In case of changing temperatures of the pumped medium In case of changing ambient temperatures or ventilation In case of plants that are sensitive to vibration When series NTWH and CTWH have impeller diameters 315, 00, and 500 and t 7 C, the double-cardanic coupling is standard. Size CTWH -/1 (ALLHEAT 0) is available with a double cardanic spacer coupling only. Base plate series NTWH/CTWH Two base plate types are available: channel steel, U-profile; and base plates with drip channel made from cast iron or steel, welded (material type depends on ). The coupling types and base plate versions can be combined with each other. Use our ALL2CAD interactive system to obtain the installation dimensions. Accessories The pump can be equipped with an optional pressureless quench fluid buffer in order to protect the mechanical seal from oxidation with sensitive heat transfer liquids. Leaks and the bearing can be monitored with ALLWEILER Smart Equipment. VM 5 GB/0.10 Ident-No

It must also be ensured that any heat can be freely dissipated into the atmosphere. Block and in-line pumps of series NBWH, CBWH, NIWH, CIWH Driven by surface-cooled IEC three-phase cage motors with axial thrust bearing, model IM V1, protection type IP55, insulation class F, performances and main dimensions acc. to DIN Attention: Motors provided by the client must contain a axial thrust bearing on the drive side for block or in-line pumps. Explosion protection The pump fulfills the requirements according to EU explosion-protection directive 9/9/EC (ATEX a) for devices in device class II, category 2 G. Classification into temperature classes according to EN depends on temperature of the pumped liquid. Refer to proposal or order documentation for the maximum permissible temperature of pumped liquid for the respective temperature classes. Note: When operating the pump in category 2, suitable measures must be provided to prevent impermissible warming of the pump surfaces during disturbance. VM 5 GB/0.10 Ident-No
