ApplicationFor the circulation of heat-transfer liquids such as hot oil or hotwater in heat transfer plants. The fluids to be handled must notcontain abrasive particles and must not chemically attack thematerials used.

Design / InstallationUncooled volute casing centrifugal pump with axial inlet, inlinedesign, single stage close coupled with magnetic coupling. Thehydraulic coverage corresponds to DIN EN 22858 / ISO 2858.

Separated by a stationary mounted containment shell, the torquetransmission from the outer to the inner rotor is accomplishedwithout contact by means of special alloy magnets. The outermagnetic rotor is mounted on to the shaft of the electric motor.The hollow inner magnets rotor is directly connected to a sym-metrical double flooded impeller, resulting into an almost zeroaxial thrust. Because the impeller is mounted between two slee-ve bearings, the resulting radial forces in the sleeve bearings arereduced by 50% for ALLMAG - irrespective of the pump series(patent pending).

Horizontal and vertical mounting is possible.

Performance data at 50 Hz

Q up to 80 m3/h pd up to 16 bar➀

H up to 55 m DNd from 25 to 50t up to 350 °C in thermal oil

up to 183 °C in hot water

➀ Inlet pressure plus internal pressure at maximum delivery head (= 0-flow)must not exceed the stated pd value.

The mentioned performance data are only to be viewed as a pro-duct/performance overview. The exact operating limits are speci-fied in the quotation and/or in the order acknowledgment.

For actual flow rates, please see hydraulic coverage and/or indi-vidual hydraulic curves. As a protection against overheating whenoperating at low flow rates, a minimum flow rate is to be maintainedaccording to the following formula:

Qmin. = 0.3 x Qη opt.

The maximum transmissible power of the magnetic coupling =appr. 30 kW at 2900 1/min. Magnets are available in lengths of20, 30, 40, 60 and 80 mm.

FlangesConnection flange: dimensions according to EN 1092-2, PN 16and/or EN 1092-1.

DriveBy three-phase squirrel-cage induction motor with fixedball bearing. Up to 2,2 kW 220/380V, including 3 kW andabove 400/660V, IP55.Where the client supplies the motor, the following must beobserved:# The motor must contain a fixed bearing on the drive side# The end plate of the motor should be made from grey cast iron# The drive-sided bearing may experience temperatures of up to

approx.90 °CThe maximum ambient temperature on site must not exceed40 °C. Non-restricted heat removal must be assured at any time.

Explosion protectionThe pump fulfils the requirements according to ECExplosion Protection Directive 94/9EG (ATEX 100a) for

equipment and equipment group II, category 2 G. Categorisationinto temperature classes according to EN 13463-1 depends onthe temperature of the pumped medium. The max. permissibletemperature of the pumped medium for the respective temperatureclasses are shown in the below table:

➀ corresponds to the pump’s temperature limitType of protection b = Monitoring of ignition sourcesType of protection c = Safe design

The temperatures specified above are based on a max. ambienttemperature of 40°C.

Note: In case of the operation of a category 2 pump, the unac-ceptable heating of the pump surfaces caused by a possible ope-rational fault must be prevented by a control mechanism. In caseof an operation with know parameters (Q, H, υ, ρ = const.), apump performance controller can be supplied with the pump todetect any operational faults.
