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. 796 2

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 1363-1 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. 796 2 3
