APPLICATION

CONSTRUCTION

The volute pumps of the series ZDH / ZHN are part of the general programme of heat transfer and circutation pumps. They are primarily used for circulation of hot water in closed pipe and vessel systems.

Casing pressure

Therefore their fields of application are energy production, heat transport and industry and here mainly in systems where hot water as heat carrier is given preference, despite its high system pressure, over oil as heat carrier.

ZDN: max 25 bar from - 30 °C to + 185 °C ZHN: max 16 bar from - 30 °C to + 120 °C max 14 bar from + 120 °C to +180 °C Please note: casing pressure = inlet pressure + zero head max test pressure = ZDN 33 bar; ZHN 21 bar

Position of branches: Suction branch axially, discharge branch radially pointing upwards.

Flanges: ZDN: The flanges correspond to DIN 2534/PN 25. Flange design ANSI 300 is possible. ZHN: The flanges correspond to DIN 2533/PN 16. Flange design ANSI 150/300 is possible.

Hydraulics: First Hydraulics. Code of this design: A./C. Second Hydraulics. Code of this design: B.

DESIGN ZDN: Horizontal, single-stage volute pumps with connections to DIN 24 256 / EN 22 858 in back pull out design. ZHN: Horizontal, single-stage volute pumps with connections and main dimensions to DIN 24255 / EN 733 in back pull out design. The series ZDN / ZHN is especially designed for troublefree pumping of hot water; up to 185 °C, with uncooled mechanical seals. The pumps have the following remarkable features: • by a special conception gas accumulations in the mechanical seal chamber are pumped independently to the ventilation. Thus a dry operation of the mechanical seal is excluded. • the back pull out design allows the disassembly of the complete bearing unit towards the drive side so that it is not necessary to detach the pump casing out of the pipe system. If a spacer type coupling is used also the loosening of the motor becomes superfluous

133.64801.52.01 E

Bearing: One grease-lubricated antifriction bearing to DIN 625 and one liquid-surrounded sleeve bearing. Code of this design: .A

Sense of rotation: Clockwise, when seen from the drive on the pump.

Shaft sealing: The shaft is sealed by an internally flushed, uncooled standard mechanical seal. Code B27: sliding material WC/carbon for hot water without abrasive admixtures temperature range up to 185 °C pressure range up to 25 bar Code BJ3: sliding material SiC/carbon for hot water without abrasive admixtures temperature range up to 180 °C pressure range up to 16 bar Other shaft seals upon request.

Heat barrier / shaft seal / bearing / feet arrangement Heat transfer plants have reached a high technical standard. Consequently the demands on the pumps for handling heat carriers have increased regarding operating reliability, environmental protection, maintenance and operating costs. On the basis of many years’ experience and latest technical know-how the ZDN/ZHN fully meets these demands. The temperature reduction makes it possible to use safely an uncooled mechanical seal up to a pumping medium temperature 185 °C resp. 180 °C.

On delivery the point ( . ) as the fourth place of the type designation is replaced in the factory by a letter. If we are informed of the motor type being selected, the coupling can be ready drilled on motor side, and we can supply the contact safety device for the coupling and the shims for equalizing out the center height. Any changes in the interest of the technical development are reserved.
