Norm-Centrifugal Pumps PN 10 Series NT
Pump dimensions acc. to DIN EN 733 with additional sizes Technical requirements acc. to DIN ISO 9905
Application For pumping pure water, industrial water, sea water, condensate, oils, brines, lyes, hot water. The liquids to be pumped must not contain any abrasive particles nor chemically attack the pump materials. Main fields of application In cooling and heating circuits in circulating, water supply, water treatment, irrigation, desalinization, dedusting and spray painting installations as well as in air-conditioning, refrigerating, swimming pool and industrial engineering. Design and series construction Horizontal volute casing centrifugal pump with axial inlet, single-flow, single or two-stage, in process design. Series construction according to the modular system. Shaft bearing in a bearing housing which can be optionally provided with a support foot. With bearing housing size 585 and 700 the foot belongs to serial equipment, with bearing housing size 228 it is generally not available. Stable mounting with feet cast on volute casing. The additional two-stage pump sizes correspond in their outer dimensions to the respective single-stage sizes. Due to the two-stage design good efficiencies and low NPSH values are achieved at high delivery heads. Capacity With the sizes according to DIN EN 733, the pump capacity exceeds the required rated power considerably. By additional sizes, the performance range acc. to DIN EN is increased. Performance data Flow Delivery head Temperature of the liquid pumped Inlet pressure Outlet pressure

Inlet pressure plus maximum delivery head must not exceed the outlet pressure.
Branch positions and flanges Suction branch: axial Delivery branch: radially upwards Flanges: Flange s: up to DN 150 acc. to EN 1092-2 PN 16 DN 200 and above acc. to EN 1092-2 PN 10 Shaft coupling and safety guarding Safety guarding according to DIN EN 294 is supplied as soon as the scope of supply includes pump, base plate and shaft coupling (acc. to DIN 740 with or without spacer element). The safety standards acc. to DIN EN 809 are met.
VM 538 GB/05.06 – Ident-No. 795 213
Bearing and lubrication By two groove ball bearings acc. to DIN 625, grease-lubricated for the whole service life, bearing clearance C3. Dismantling of the insert unit
When using the spacer coupling the insert unit can because of the process design be dismantled towards the motor side, whereas the volute casing and the motor may remain on the base plate and the pipes on the volute casing. Combination of structural components The table on page 3 shows the combination possibilities of structural components of all NT sizes. The modular system allows reduced stockkeeping of spare parts. Explosion protection The pump fulfils the requirements according to EC Explosion Protection Directive 94/9/EG (ATEX 100a) for equipment of equipment group II, category 2 G. Categorisation into temperature classes according to EN 13 463-1 depends on the temperature of the pumped liquid. The max. permissible temperature of the pumped liquid for the respective temperature classes are shown in the specific order data sheet. Note: In Note: In case of the operation of a category 2 pump, the unacceptable heating of the pump surfaces caused by a possible operational fault must be prevented by a control mechanism.

Series NT Negligible axial thrust by fine adaptation of the relief bores.
Pressure safe casing parts designed for high reliability of operation.
Flanges according to DIN EN 1092-2 PN 10/16, other flange designs possible.
Connection dimensions and capacities according to DIN EN 733.
Shaft sealing by mechanical seal or gland packing according to the operating conditions. Groove ball bearings rigid and lubricated for the whole service life.
No offset of the shaft because of one-piece bearing housing.
Optimized hydraulic parts according to DIN EN 733 with very good efficiencies and NPSH values.
Two-stage sizes with their outer dimensions correspond to the respective single-stage sizes.
Large delivery heads with two-stage sizes (2/25-200/01, 2/32-200/01, 2/40-250/01, 2/50-250/01). The connection dimensions correspond with the single stage design.

Adaptation to changing operating conditions possible by turning down the impeller.
Large selection of materials.
Process design; when dismounting the pump the volute casing remains in the piping.
By additional pump sizes performance range according to DIN EN 733 is increased.
Reduced stockkeeping of spare parts due to use of as much non-variable parts as possible (modular system).
