APPLICATION

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

Therefore their fields of application are

energy production,

heat transport and

industry

and here mainly in systems where hot water as heat carrier is givenpreference, despite its high system pressure, over oil as heat carrier.

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 andmain dimensions to DIN 24255 / EN 733 in back pull outdesign.The series ZDN / ZHN is especially designed for troublefree pumpingof hot water; up to 185 °C, with uncooled mechanical seals. Thepumps have the following remarkable features: • by a special conception gas accumulations in the mechanical

seal chamber are pumped independently to the ventilation. Thusa dry operation of the mechanical seal is excluded.

• the back pull out design allows the disassembly of the completebearing unit towards the drive side so that it is not necessary todetach the pump casing out of the pipe system. If a spacer typecoupling is used also the loosening of the motor becomessuperfluous

CONSTRUCTION

Casing pressure

ZDN: max 25 bar from - 30 °C to + 185 °CZHN: max 16 bar from - 30 °C to + 120 °C max 14 bar from + 120 °C to +180 °CPlease note:casing pressure = inlet pressure + zero headmax 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.

Bearing:

One grease-lubricated antifriction bearing to DIN 625 and oneliquid-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 standardmechanical seal.Code B27: sliding material WC/carbon

for hot water without abrasive admixturestemperature range up to 185 °Cpressure range up to 25 bar

Code BJ3: sliding material SiC/carbonfor hot water without abrasive admixturestemperature range up to 180 °Cpressure range up to 16 bar

General comments:

For equipping heat transfer plants, which are operated with hot water, a complete programme of additional series is available for an outputrange up to 1200 m3/h:

series ZLN volute pumps to DIN 24255/EN 733, tmax 160 °C

series ZEN volute pumps to DIN 24256/EN 22858, tmax 230 °C PN 40

series ZLI PN 25 hot water design, volute pump on the basis of DIN 24255/EN 733 as INLINE-construction, tmax 150 °C

series ZTN design with base plate tmax 350 °C for heat transfer oil.

Pumps for heating / cooling operation on request.

Technical documentation on these programmes will be supplied on 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 carriershave increased regarding operating reliability, environmentalprotection, maintenance and operating costs. On the basis of manyyears’ experience and latest technical know-how the ZDN/ZHN fullymeets these demands.The temperature reduction makes it possible to use safely anuncooled mechanical seal up to a pumping medium temperature185 °C resp. 180 °C.
